| Abstract: | Brinjal (Solanum melongena) is a popular vegetable crop in Bangladesh cultivated all the year round. Infestation of different insect pests is a serious issue which hampers the production of brinjal. As the farmers in Bangladesh applying different chemical insecticides without following proper dosage or pre-harvest interval to control insect infestation, pesticide residue remains even after harvest and different health hazards are increasing after consuming these vegetables. The present study was conducted to assess some non-toxic botanicals against leafhopper (Amrasca biguttula biguttula) in brinjal which is one of the most devastating sucking insect pest in both summer and winter. Infestation of leafhopper was observed highest during vegetative stage. Application of neem oil performed best to reduce the mean number of leafhopper 5.73/plant in this experiment. Highest 57.73%, 50.83% and 49.19% reduction over control regarding to the number of leafhopper per plant was observed in case of neem oil application, tobacco leaf extract application and neem leaf extract application respectively. Application of neem oil and tobacco leaf extract gave 59.13% and 43.19% percent reduction over control regarding to the leaf infestation by leafhopper per plant respectively. Application of garlic extract, mustard seed extract and papaya leaf extract also observed effective to control the infestation of leafhopper in brinjal. As incidence of leafhopper has a negative impact on the yield of brinjal, use of botanicals can be a good alternative to control this insect. |
