Efficay of Plant Extracts and Vermiwash on Dynamics of Thrips Population and Yield of Chillies
S. Sendur Kumaran
Abstract: Any program designed to change pesticide use patterns in chilli cultivation help reduce pesticide usage, incorporation of biorational materials and a knowledge of which materials can be safely integrated is critical and need of the hour for a number of reasons. With this Knowledge, Field trials were carried out during Rabi/summer 2014-15 at Krishi Vigyan Kendra, Kundrakudi to study the effect of Prosopis juliflora and Notchi leaf extracts in combination with vermiwash in different dilutions are studied to protect the crop damage against thrips (Scirtothrips dorsalis) and its contribution to the yield in chilli cv. Priyanka under micro irrigation situations. The results revealed that combined application of Prosopis juliflora leaf extracts @ 20 ml and Notchi leaf extract @ 20 ml and vermiwash at 12 ratio water recorded significantly lesser population of thrips with 228.20q/hec. of dry chilli per hectare followed by Notchi (vitex negundo) leaf extracts @ 20 ml in combination with vermiwash at 12 ratio water and registered significantly higher yield were at par with plants grown that received chemical pesticide.
