Abstract :

In India the farmers mostly rely on a mixture of chemical pesticides to limit the losses from pests and disease. Inappropriate handling and unsafe spraying of the agrochemicals cause high risk of health hazards. Degraded pesticide resulted in soil and groundwater pollution has nutritionally imbalanced and unproductive lands. So to reduce the pesticide residue incidence an an eco-friendly alternative is the need of the hour. Therefore, Neem based pesticides are more attractive biopesticides in integrated pest management programs (IPM) as they diminish the risk of exposing natural enemies of pests. The usage of neem biopesticides has developed as promising alternate to chemical pesticides when used in IPM. Neem oil based formulations have been tried against M. incognita as seed and bare root dip treatment was carried out in tomato. Soil was treated with neem oil and compared with carbofuran and untreated control. Neem oil was applied at two different dosages (4 litres/ha and 5 litres/ha) and Carbofuran 3G @ 1 kg/ha. Neem oil was applied before planting by mixing with organic fertilizer (1000 kgs) and applied as soil drench before planting.
