Mak Student’s Push-Pull App to Help Farmers Control Maize & Sorghum Pests
By Jane Anyango
Makerere University student Paul Mugisha in collaboration with a team of scientists from the International Centre of Insect Physiology and Ecology (ICIPE), Keele University and Leeds University has developed a mobile app to help maize and sorghum farmers to control pests without using pesticides.
Paul Mugisha is undertaking a Master of Science in Plant breeding and Seed systems at Makerere University’s Department of Agricultural Production, School of Agricultural Sciences under the College of Agricultural and Environmental Sciences (CAES). Mugisha is also the Chief Executive Officer (CEO) Agape Innovations Ltd.
The purpose of this app is to enable a farmer to do push-pull on his garden without interacting with an extension agent but purely using his mobile phone which does not only solve the problem of scarcity of extension workers, but also, prevents the spread of COVID-19.
The new app code-named, “the Push-Pull App”, was launched and made available for use on Google play store on 9th August, 2021 by an international team of scientists to support farmers across Africa to use innovative, environmentally-friendly techniques for evading crop pests.
In a press release issued during the launch, scientists noted that African smallholder farmers face major challenges from insect pests such as fall armyworm, and weeds such as striga that can destroy their crops. Fall armyworm is a serious threat to food security and livelihoods and already affects at least 400,000 hectares, causing crop losses worth an estimated $3 billion a year.
In the release, the “Push-Pull technology” was described as a novel method of crop management and a solution which can massively reduce farmers’ losses from pests and increase their harvest sizes, whilst avoiding the need to use harmful and expensive chemical pesticides.
The media release in part states that the “Push-Pull technology” is a scientific method of planting crops like maize and sorghum, alongside particular species of forage grasses and legumes that repel pests and supress weeds.
“It was developed by scientists at ICIPE in Kenya and partners and is designed to protect the plants against devastating pests like the fall armyworm and the striga weed, with the companion plants also improving soil fertility. But a major challenge is how to communicate advice and information about this to millions of smallholder farmers in sub-Saharan Africa, to get as many of them using the technique as possible.

To help address this challenge, a new mobile phone app has been launched by Agape Innovations Ltd, in collaboration a team of scientists from the University of Leeds, University of Keele and ICIPE.
The app is part of a larger project called, “Scaling up Bio control Innovations in Africa”, funded by the Global Challenges Research Fund, which seeks to understand how biocontrol methods have been used across Africa and to encourage their uptake”, part of the media release states.
The Principal Investigator (PI) Dr Steve Sait, from the University of Leeds’ School of Biology, said the Push-Pull method of pest control is decades old and is used successfully by thousands of smallholder farmers across Africa.
“We hope that this collaboration, and this new app, can help us extend knowledge of this technique to potentially millions of other farmers who could be benefitting from it. Compared to chemical pesticides, Push-Pull costs less money to the farmer, results in less damage to their crops, and it avoids harming other insect species that play valuable roles in the ecosystem.”
The PI said, research by the scientists behind the Push-Pull technique, including Keele’s Professor Toby Bruce, has proven that odours released by the companion plants can effectively repel fall armyworm and protect crops against the pest.
Early adopter farmers according to the scientists have had great success with this technique, reporting five times less fall armyworm damage and a doubling or even tripling of crop yield, showing the huge potential this has for farmers and crop-producing smallholders.In addition he said, It also reduces the environmental impact of farming by protecting against pests without using pesticides, as well as improving soil quality without inorganic fertilisers.
Dr. Steve Sait explained that the Push-Pull App has been developed by Agape innovations and is available on Android phones, designed to work on the basic smartphones that are being increasingly used by smallholder farmers in Africa.
The App he adds, gives farmers information they need to get started with Push-Pull farming, and is not only free but 100% available offline, meaning a lack of internet connection in rural regions will not affect its function.
“The ultimate goal is to provide a resource for farmers that is informed by science, protects their crops and improves their harvest, which they can access any time of day from anywhere in the world”.
Professor Toby Bruce from Keele University’s School of Life Sciences said the team was excited to see if this App can serve as a vehicle for taking practical information to the farmer.
“It is designed to share key details about how to get started with Push-Pull. We hope this will increase the number of farmers taking up this innovative approach that provides real benefits by improving crop protection and food security.”Prof. Toby Bruce said.
Makerere University student- the App designer Mr.Paul Mugisha, who is also CEO of Agape Innovations Ltd underscored the significance of ICT in addressing farmers’ challenges in critical challenging times involving natural calamities.
“With the world going digital and uncertainties like Covid-19 amplifying the challenges of physical interactions, ICT is so vital in today and tomorrow’s agriculture. At Agape, we built the Push-Pull app as a global tool to equip a farmer with all that is needed for a successful push-pull garden.
Embedded with audio, visual and graphical expressions we are certain that the Push-Pull app will be relevant to maize and sorghum farmers worldwide for both today and tomorrow in controlling FAW, Striga and Maize stalk borer”, Mr. Mugisha explained.
Mugisha said, in this Push and Pull technology, maize is intercropped with legumes, and forage grasses are planted around this intercrop as a border around the garden. The legume intercrop produces chemicals that repels the pests from the garden (push) while the forage grass in the boundary produces chemicals that attracting insect pests (pull). In addition, the chemicals released by the intercrop roots also cause abortive germination of the parasitic striga weed, providing effective control of this stubborn weed. The legume also fixes nitrogen into the soil thus boosting soil productivity..
More about the PUSH-PULL App
What is Push-Pull App?
PUSH-PULL app is a mobile application that serves as a guide to a farmer whose interest is to control pests in maize and sorghum (like fall army worm and maize stem borer) without using chemicals and also improve the soil conditions without using artificial fertilizers.
The PUSH-PULL app acts as an extension agent on a farmer’s mobile phone providing information about a farming method called push-pull that was developed by scientists at ICIPE, a method that uses natural means for pest control and soil improvement.
What problem is PUSH-PULL app trying to solve?
With PUSH-PULL app, a farmer can access information at anytime of the day be at 6 am on a Sunday morning or at Thursday mid-night, something that is not possible with an extension agent. With this app, a farmer can access information anywhere, whether in his car, in his garden or on his way to the shop. Information is conveniently available for the farmer. With this app, farmers all over the world can access the information on their phones. Whether in Cambodia, Ecuador or in Burkina faso, push-pull information is available

Makerere Hosts Inaugural Falling Walls Lab Competition as Innovators Pitch Solutions to National Challenges
Students and researchers from Makerere University and other institutions pitched 12 innovations addressing challenges in healthcare, clean energy, agriculture, waste management and community resilience during the inaugural Falling Walls Lab Kampala, held at the School of Public Health Auditorium, Makerere University.
The competition brought together emerging innovators to present solutions to practical challenges through a three minute pitch, followed by questions from a panel of judges.
Modelled on the Falling Walls format that originated in Berlin, the event required each participant to identify a “wall” a problem or barrier, and demonstrate how their innovation seeks to break it down.
Mudhasi wins with newborn jaundice screening device
Andrew Mudhasi of Makerere University emerged as the overall winner with a score of 90 per cent for a low cost medical device designed to improve newborn jaundice screening across different skin tones.
Mudhasi explained that the device uses optical sensor technology and a skin tone targeting algorithm to provide a rapid reading, with the aim of helping nurses and clinicians identify jaundice more efficiently.
During questions from the jury, Mudhasi said the device had not yet been tested on actual babies but had undergone laboratory testing using simulated skin tones.
He reported an accuracy rate of 94 per cent when the device was compared with laboratory spectrophotometers.
The innovation is intended initially for use in clinics and hospitals, with Mudhasi saying the team is also considering a version that could eventually allow mothers to screen babies at home.
Mudhasi’s innovation has previously received recognition at the African Business Concept Challenge and the iF Design Student Award, according to his presentation.
Rhonda’s innovation tackles diaper waste
Rhoda John of the University of Nairobi emerged in second place with 89.6 per cent for an innovation addressing the problem of used diaper waste.
Under the theme “Breaking the wall of diaper waste and drug soils,” Rhonda explained that her team extracts sodium polyacrylate, the absorbent polymer found in diapers, and replaces the sodium with potassium.
The resulting potassium based superabsorbent material is designed to act as a “water battery” in soil by absorbing and retaining water for plants during dry periods.
John said testing showed a 99 per cent increase in germination and a 23 per cent increase in drought resistance.
The innovation also seeks to reduce the amount of used diapers ending up in landfills and the environmental effects associated with their decomposition.
During the question and answer session, John explained that her team was working with government environmental officials in Nairobi on a pilot collection system to address the challenge of gathering used diapers at scale.
Mahera takes third place with herbal peptic ulcer treatment
Stuart Mahera of Makerere University finished third with 86.2 per cent for a herbal formulation targeting peptic ulcers.
Presenting under the theme “Breaking the wall of Nature and Modern Medicine,” Mahera argued that conventional treatment for peptic ulcers can involve multiple medicines and may be associated with side effects and antimicrobial resistance.
His proposed formulation, MARAC capsules, is intended as a monotherapy, combining properties required for peptic-ulcer treatment in a single capsule.
Mahera said his team had carried out quality control work, including characterisation and dose quantification, and had conducted preclinical trials on laboratory mice.
He also told the jury that an application had been submitted to the National Drug Authority as the team awaits the next stage of the regulatory process.
According to Mahera, the proposed seven day treatment would cost about Shs21,000, compared with the existing 14 day treatment approach.
Innovators present solutions to practical challenges
The remaining presentations covered a wide range of challenges.
Esther Nakungu of Utamu University presented Agri-Track, a digital record keeping solution intended to improve visibility, accountability and management of farm operations and financial information.
Dr. Jimmy Chachiga, a Makerere University participant, presented a solar photovoltaic cooker with a heat storage system designed to provide a cleaner and more reliable cooking option during both sunny and non sunny periods.
His presentation focused on reducing dependence on biomass fuels and addressing the challenges associated with intermittent solar energy.
Abdul Noor Luttamaguzi, a PhD student and senior government fisheries officer, presented a mobile application aimed at helping fish farmers and extension officers report, track and manage disease outbreaks.
Henry Duke Tamale presented a herbal cream targeting antibiotic resistant biofilm infections associated with diabetic foot ulcers.
Marvin Seruwu proposed adapting existing near infrared brain monitoring technology to help detect extra-axial brain bleeds in health facilities where access to CT and MRI equipment is limited.
His proposal seeks to repurpose existing technology towards a diagnostic need that could be particularly important in settings where advanced imaging facilities are not readily available.
Kennedy Kisame presented a poultry alert and diagnosis system combining satellite weather information with computer vision disease detection. The proposed system could be accessed through a smartphone application, SMS or USSD, making it potentially usable by farmers with limited internet access.
Frank Atwiine proposed a solar powered mobile diagnostic van designed to bring ultrasound and other diagnostic services closer to rural communities.
Johnson Makmot, a software and blockchain developer, presented a platform that combines GPS tracking and blockchain-based tokens to incentivise and verify plastic-waste collection in Kampala.
Dr. Nelson Ndugu, from a partner university, presented an artificial intelligence tool designed to translate agricultural research publications into local Ugandan languages and generate voice notes for radio-based extension delivery.
The final presentation came from Dr. Juliet Akola, a Ugandan post doctoral researcher at Mangosuthu University of Technology in South Africa.
Akola presented a community digital resilience initiative focused on mapping risks in Kampala’s informal settlements, including flooding, fire, poor sanitation, waste management and inadequate infrastructure.
Her proposal seeks to combine local community knowledge with geographical information systems and link identified risks to action plans involving municipalities and other stakeholders.
Nawangwe calls for more investment in innovation
Closing the event, Prof. Nawangwe congratulated all the participants and described their presentations as an important beginning for Makerere University, Uganda and the wider region.
Drawing on his experience attending the Falling Walls conference in Berlin, the Vice Chancellor said initiatives of this nature are important because innovation will play a major role in determining the future of countries.
He encouraged participants to make their pitches more precise by clearly identifying the problem they are addressing, explaining their proposed solution and demonstrating what they have already achieved.
Prof. Nawangwe also welcomed the participation of innovators from other universities and countries, noting that the Kampala event had attracted participants beyond Makerere.
He thanked the Africa Office of the Falling Walls Foundation for its role in bringing the initiative to Makerere and encouraged continued support for innovation.
The Vice Chancellor further linked innovation to Uganda’s growing youth population and the need to develop home-grown solutions to address challenges such as youth unemployment.
The inaugural Falling Walls Lab Kampala ultimately provided a platform for innovators to move ideas beyond the classroom and laboratory and demonstrate how research, technology and creativity can be applied to challenges affecting communities.

CAES Freshers Urged to Embrace Academic Excellence to Become Agents of National Transformation
Orientation is an important first step in helping newly admitted students transition into a new academic and social environment. Beyond introducing students to institutional structures and services, orientation provides an opportunity to set expectations, clarify responsibilities and inspire students to approach their university journey with purpose. For the 2026/2027 intake at Makerere University’s College of Agricultural and Environmental Sciences (CAES), the orientation emphasized the importance of making the most of the university experience, pursuing academic excellence, and developing the knowledge, skills, and values needed to become responsible citizens, innovative professionals, and agents of national transformation.
The CAES Freshers’ Orientation, held on Thursday, 6th August 2026, at the School of Agricultural Sciences (SAS) Quadrangle, provided newly admitted students with an opportunity to familiarize themselves with the College’s academic programmes, administrative structures, technological resources, library services, counselling and other student support services. Beyond introducing the freshers to the University environment and the resources available to support their academic journey, the orientation emphasized the broader purpose of university education. Students were encouraged to view their time at Makerere not merely as a pathway to academic qualifications, but as an opportunity to develop relevant competencies, build character, discover their potential and acquire the knowledge and skills necessary to address real-world challenges and make meaningful contributions to society.
CAES: A College of Opportunities
Welcoming the freshers to CAES, the Principal, Prof. Gorettie Nabanoga, urged them to recognize the significance of the opportunity they had received to study at Makerere University and to use their time at the institution wisely.
Prof. Nabanoga reminded the students that university represents a critical stage in their journey towards becoming responsible and productive citizens. She cautioned them against letting the excitement, newfound freedom and social opportunities distract them from their academic responsibilities.
“You are at the tail end of your journey to becoming important citizens, and therefore you need to use your time at the University effectively,” she said, urging the students to begin thinking about what they wish to become from the very beginning of their university education.
She emphasized that success at university requires discipline, commitment and a clear sense of purpose. The freshers were encouraged to take ownership of their education and make deliberate decisions that would contribute to their personal and professional growth.
According to Prof. Nabanoga, CAES is strategically positioned to prepare graduates who can respond to some of the most pressing challenges facing Uganda and the wider world, particularly in food production, agriculture, environmental sustainability and entrepreneurship.
“CAES is at the centre of national development. No life exists without food and a conducive environment,” she noted, describing CAES as a “college of opportunities” where students are equipped with the knowledge and skills to become change agents.
“At CAES, we focus on skilling you to become change agents to feed nations and to protect the environment, and to become job creators,” she said.
Prof. Nabanoga further encouraged the freshers to take advantage of the expertise available within the College, particularly by actively engaging with their lecturers and seeking guidance whenever they encounter academic or other challenges.
She also underscored the importance of investing in young people as future leaders and contributors to national development, noting that sustainable transformation requires a generation equipped with the skills, values and capacity to take on leadership and other critical responsibilities.
CAES Human Capital Critical to National Development
Speaking on the relevance of CAES to Uganda’s development agenda, the Deputy Principal, Prof. Bamutaze, highlighted the College’s responsibility to produce the human capital required to drive the country’s socio-economic transformation.
He noted that Uganda’s development priorities, including agro-industrialization, tourism and mineral-based development, require innovative, skilled and dynamic human resources capable of turning opportunities into tangible solutions.
“The country desires innovative and dynamic people who can contribute to its socio-economic development,” he said.
Prof. Bamutaze encouraged the freshers to take their education seriously and use their time at Makerere to develop the competencies, creativity and innovative mindset needed to respond to emerging national and global challenges.
Students Urged to Become Problem Solvers
The Dean of the School of Agricultural Sciences, Dr. John Baptist Tumuhairwe, explained that the School is committed to producing graduates capable of identifying challenges and developing practical solutions.
He urged the students to make academic excellence a guiding principle throughout their university journey, emphasizing that consistent effort, discipline and commitment would be critical to their success.
Dr. Tumuhairwe also stressed the importance of respect, encouraging students to respect themselves, their colleagues, lecturers, administrators and the wider University community.
He cautioned the freshers against behaviours and activities that could undermine their academic progress and future prospects, particularly betting, drug abuse and irresponsible sexual behaviour.
The Dean further encouraged the students not to underestimate the programmes they had been admitted to. He noted that every programme presents opportunities for success when students remain committed, focused and willing to work hard.
He urged the freshers to take ownership of their academic journeys rather than judging their programmes solely on the basis of perceived popularity or immediate career prospects.
Freshers Encouraged to Settle Down and Focus on Excellence
Representing the Dean of the School of Food Technology, Nutrition and Bioengineering, Prof. Ivan Muzira Mukisa encouraged the freshers to settle into university life quickly and begin working towards academic excellence from the outset.
He cautioned them against wasting time and urged them to develop productive habits early, noting that the routines and discipline established during the first year can significantly influence their academic performance throughout their university journey.
Prof. Mukisa emphasized the importance of effective time management and encouraged students to strike a healthy balance between academic responsibilities and social activities.
He also highlighted the value of teamwork, noting that the ability to work collaboratively is an important skill both within the University and in the professional world.
The students were further encouraged to seek guidance whenever they encounter difficulties instead of struggling with challenges on their own. They were reminded to make use of the academic and student support structures available within the College and University.
Similarly, the Dean, School of Forestry, Environmental and Geographical Sciences, Prof. Revocatus Twinomuhangi urged the students to focus on academic and professional success.
Freshers Introduced to University Services and Policies
