Abstract

The experiment was carried out during Rabi season in the year 2015-16. Five crops viz. maize, sesamum, broad bean, niger and buckwheat, were used as border crop in tomato field. It was compared with alternate spray of dimethoate (0.05%) and lambda cyhalothrin (0.005%). Dimethoate was sprayed at 80 and100 DAT and lambda cyhalothrin was sprayed at 90 and 110 DAT. Lowest incidence in tomato was recorded in alternate spray of chemical pesticides. Amongst the different crop used as border crop, maize as border crop recorded
significantly lower incidence of Helicoverpa armigera than the other border crops. Farmers can adopt the practice of intercropping in tamato with maize to reduce the population of fruit borer.
