This study investigated the effect of applying selected banana pest control treatments on management of banana weevils. The data was collected on 283 banana plants picked at random; from 29 farmers selected using a snowball sampling technique. Treatments used were ethnomedicinal products, synthetic chemicals, cultural practices in plantation planted from suckers and those planted from tissue culture. Since data was spatially collected, it was analyzed using Restricted Maximum likelihood Estimator (REML). REML was used to estimate the PCI after a square root transformation. The statistical analysis indicated a significant difference between plantations where synthetic chemicals, clean planting materials (tissue culture), cultural practices and ethnomedicinal products were used. There was also significant variation resulting from different varieties grown. However, there was no significant variation resulting from the response of different varieties to the different treatments. Results also indicated that garden where the cleaning materials had been used had the least percentage of banana weevil infection. This study found out that there was no significant difference in damage caused by banana weevils in banana plantations where synthetic chemicals and ethnomedicinal extracts were applied. Thus given the results, the study concluded that ethnomedicinal products can be used by farmers to manage banana weevils. The study recommends that further studies should be carried out to assess efficacy of the identified potential plants with pesticidal properties under controlled experiment.

Introduction - Cooked bananas, also known as matooke, are the main source of food in Uganda’s Central, Western, and Mt. Elgon regions. Recently, the production of bananas has been seriously threatened by numerous pests and illnesses. Nematodes and banana weevils are major pests, and bacterial infections and panama wilt are the most common diseases. There hasn’t been sufficient research that address women’s engagement in the usage of biorationals in the study area. A study that was conducted in the Central Ugandan districts of Masaka and Mpigi assessed the extent to which women used biorationals to treat pests and diseases that affects bananas, as well as farmers’ assessments of how efficient these treatments were. Methodology - Using both quantitative and qualitative data, social economic approaches were applied. A structure questionnaire and key informant interviews were used. A logistic model was used to determine the farmers’ perceptions of the effectiveness of biorationals in getting rid of banana weevils. The survey’s sample size was 144 house-holds, or one hundred forty-four. Organic farmers were identified using snow ball sampling, while the remain-ing farmers were chosen using a random sampling technique. The sample was chosen using an undisclosed population sampling method Results & Discussion - According to the logistic model, women were more likely than men to consider biorationals to be effective. Knowledge (awareness) of the product played a key role in farmers’ perception of and use of biorationals goods. Farmers with a secondary education embraced and evaluated the usage of biorationals as being extremely important Conclusion - According to this approach, women’s participation, farmers’ training in banana production, and the usage of livestock products are all crucial issues that need to be addressed in order to increase the use of biorationals in banana production.
