The combinations of vermiwash with bio-pesticides-A boon for crop productivity

Abstract

Imbalance use of chemical fertilizers and pesticides has posed a serious threat to the environment, animal and human health and also cause disturbance to the soil ecosystem. The biological wastes include those wastes which are produced by living being, either in the form of agricultural wastes, municipal solid wastes, kitchen wastes or animal excreta. The biological wastes are serious problem for society. The vermicomposting is the suitable way for proper management of biological wastes and production of vermicompost. The vermicompost is the best alternative of synthetic chemical fertilizers because it is eco-friendly, less-expensive and no hazardous to human, animal and environment. The vermicompost prepared from the different combinations of feed materials of buffalo dung with gram bran and water hyacinth wastes with the help of earthworm Eisenia fetida and liquid biofertilizer vermiwash were extracted with the help of vermiwash collecting device. The different combinations of extracted vermiwash were mixed with different biopestcides like garlic bulb, neem plant part and neem based bio-pesticides. The effect of foliar application of vermiwash with bio-pesticides on the growth, flowering, and productivity of Cicer aritinum and Cajanus cajanas well as pest infestation of Helicoverpa armigera were observed. The foliar application of vermiwash with bio-pesticides increased the growth, productivity, early flowering and reduces the pest infestation of Helicoverpa armigera.The vermiwash with garlic bulb extract have significant growth, productivity, early flowering and minimize the pest infestation of Helicoverpa armigera followed by vermiwash with neem oil.
