Author(s): Tomato, Groundnut Bud Necrosis virus (GBNV), Pesticides, Tamil Nadu.

Abstract: Tomato is one of the important vegetable crops cultivated in throughout the world. It is affected by many causal agents such as fungal, bacterial, viral and nematodes. Among viral diseases, tomato leaf curl and groundnut bud necrosis disease are causing considerable damage to the crop and yield. The groundnut bud necrosis virus is a Tospovirus group, which could be transmitted by many thrips species in the field on various crops. Result revealed that the maximum number of 4.0 thrips per plant was recorded in Krishngiri district and minimum number 0.8 thrips per plant was recorded in Perambalur district. Correspondingly, maximum GBNV incidence of 82 per cent was recorded in Krishnagiri district and the minimum of 44 per cent disease incidence was observed in Peramabalur district and usage of pesticide pattern revealed that the Imidacloprid 17.8 % SL (62.5 per cent), followed by Thiomethxam 25 % WG, Dimethoate 30 EC (50 per cent) and Azadirachtin 1% (37.5 per cent) pesticides are frequently used in major tomato growing districts of Tamil Nadu.
