Abstract

Gandhi bug Leptocoryza varicornis is one of the major pests of rice crop which reduces the crop yield. Foliar spray of single and binary combination of vermiwash with biopesticides prevents loss of panicle and increase the crop yield. Significant decrease in Leptocoryza varicornis population was observed after foliar spray of vermiwash with neem oil followed by aqueous garlic and annona leaf extract. The combination of neem oil with vermiwash caused complete removal of the L. varicornis infestation. The vermiwash (obtained from buffalo dung and municipal solid wastes) with neem oil or garlic bulb extract is better alternative to manage the Gandhi bug population in rice crop during panicle formation stage which ultimately enhances the yield. The organic farming is the boon for farmers. The aim of present study to enhance the growth, productivity of rice crop and decreased its pest infestation by the used of vermibiotechnology with different biopesticides.
