Capsicum (Capsicum annuum L.) is the major offseason veggetable crop under protected cultivation and fetches premium price in market. However, the polyhouse environment is very congenial for the development of many diseases and pests, among which broad mite (Polyphagotarsonemus latus (Banks)) and powdery mildew (Erysiphe sp.) are of utmost importance that hinder capsicum productivity. Hence, a study was conducted on evaluation of miticides and fungicides against broad mite and powdery mildew at three locations viz., Rail, Bara and Sathwin in district Hamirpur during 2010. Sprays were done at the initiation of pest infestation. The miticides and fungicides were sprayed on alternate days to rule out any incompatibility. The observations on per cent plant infestations by broad mite and powdery mildew were recorded 10 days after the treatments and average of the different locations was worked out. The perusal of data revealed that mite infestation was lowest (13.33%) in chlorphenipyr treatment whereas the other two miticide treatments were statistically at par with each other. Per cent plant infestation due to powdery mildew was lowest in hexaconazol treatment (26.67%) followed by Sulfex powder (33.33%). Highest per cent increase in yield over control (71.43%) was recorded in chlorphenipyr and hexaconazol treatment which were significantly effective against both the pests.
