dc.description.abstractField assessments were carried out in seven districts of eastern and northern Uganda to establish pest infestation of cowpea (Vigna unguiculata) and the extent of insecticide usage to control these pests. More than 60 % of the farmers in eastern Uganda applied insecticides to control cowpea pests whereas no farmers in the northern region used chemieels for this purpose. The extent of pest infestation at different crop growth stages appeared to influence pesticide application, with mostlarmers spraying during the vegetative (30 %) and flowering (50 %) stages. and only a few at podding (10 %). There was evidence 01 ineffective/uneconomical use of insecticides. On-farm trials indicated that insecticide protection at all crop growth stages gave the best control. leading to yield gains 01 more than 50 %. Spraying during vegetative and flowering stages was also effective. giving yield gains of about 40 %. A three-spray programme (at vegetative growth. flowering and podding) was most profitable in the short rainy season at Serere (marginal return = 6.08) and second best in the long rainy season at Kabanyolo (marginal return = 4.35).
