Tomato (Solanum lycopersicum L.) is one of the most widely grown vegetable crops in the world; they are excellent source of various micronutrients and antioxidants. In Tamil Nadu the area under tomato cultivation is 38.78 lakh ha with the production of 841.21 million tonnes. In Tamil Nadu, the major tomato producing districts are Vellore, Salem, Dharmapuri, Coimbatore, Trichy, Thiruvannamalai, Madurai, Dindugul, Erode and Krishnagiri. PKM 1, Marutham, Paiyur1, COTH 2 and Sivam are the important varaities/hybrids grown in Tamil Nadu. Among various diseases, Fusariumwilt of tomato caused by Fusarium oxysporum f.sp lycopersici (Sacc.) Synder and Hansenis considered as one of the major constraints to tomato production. Many effective pesticides have been tested against the pathogen but not considered as long term solution. Therefore, the present investigations were undertaken with an objective to isolate and test effective B. subtilis and Trichoderma viride along with the new generation fungicide Azoxystrobin 23% SC against wilt disease of tomato and assess the molecular mechanisms involved in the disease suppression. Combined application of seed treatment with consortium (B.subtilis and T.viride) @ 10.0 ml / Kg of seeds+ seedling root dip of consortium (B.subtilis and T.viride) @ 500ml/10 lit of water + Azoxystrobin 23% SC as Foliar Spray @ 0.1% on 45 DAT significantly reduced the tomato Fusariumwilt to the minimum and increased the plant growth and yield parameters of tomato to the maximum under pot culture and field condition. Thus, the results of the present study have clearly proved that with the combination of seed treatment seedling root dip of consortium (B.subtilis and T. viride) along with the new chemical Azoxystrobin 23% SC, it is possible to reduce the amount of chemical being used and also to reduce the number of applications viz., with only one spray of the chemical at 45 DAT the tomato Fusarium wilt incidence could effectively be managed with enhanced fruit yield of Tomato.
