UoN, MKU collaborate to train Machakos farmers on biological pest control

Farmers in Machakos County have been encouraged to adopt the use of biological pesticides as a means of mitigating climate change and addressing the environmental harm caused by the prolonged use of chemical pesticides in farming.

A training exercise for farmers was organised in the Kabaa area of Machakos County by the University of Nairobi in collaboration with Mount Kenya University (MKU) and other partners.

Speaking during the training, Prof. Cecilia Moraa Onyango, an associate professor in the Department of Crop Science and Crop Protection at the University of Nairobi, stated that the move will help farmers who spend excessive amounts on chemical pesticides save money, reduce their use of harmful pesticides, and increase their yields.

“Embracing biological pesticides offers a sustainable solution, reducing costs for farmers while simultaneously protecting our delicate ecosystem,” Prof. Onyango stated, emphasising the dual benefits of the transition.

Dr Allan Mweke a lecturer from MKU’s Department of Animal Health and Production, said the new farming technology of using biological pesticides will impact farmers struggling to boost production due to high level of resistant pests on farm produce and prolonged use of chemical pesticides besides reducing interceptions of Kenyan produce in international markets due to presence of harmful pesticides levels beyond acceptable maximum residue levels occasioning farmers and exporters huge losses.

“Biological pesticides provide a viable alternative, helping farmers overcome these resistant pest challenges and ultimately achieve higher, more consistent yields,” Dr. Mweke affirmed.

The training session, which saw the participation of over 300 farmers from across Machakos County, aimed to equip them with the knowledge and practical skills necessary to implement these environmentally friendly pest control methods.

The project titled: Advancement and adaptation of agricultural biologicals to meet sub-Saharan Africa smallholder farmers’ needs and build sustainable food systems (AgBio4SSA) is funded by National Research Fund and is part of a regional project aimed at promoting sustainable farming practices in Kenya, Tanzania and South Africa.

In a related development, MKU will be holding its Annual Tree Planting Exercise on Friday morning11th July 2025 at the Pavilion Graduation Square in Thika town. “We’re targeting to plant over 1,000 tree seedlings as we go green and celebrate our 27th Graduation Eve,” the university says in a statement while inviting this year’s graduates, students, lecturers, management and stakeholders to participate in the green environment exercise.

Last month, MKU Chancellor, Prof John Struthers announced the conferment of degree and various University Awards at the 27th Graduation ceremony will be held on August, 8, 2025.
