Spinosad, a mixture of spinosyn A and spinosyn D, produced by a soil actinomycete Saccharopolyspora spinosa Mertz & Yao. It has been found to be effective for the control of a number of pests of tomato (Lycopersicon esculentum Mill.; synonyms of Solanum lycopersicum) namely, fruit borer (Helicoverpa armigera), leaf miner (Liriomyza spp.), white fly (Bemicia tabaci), etc. The persistence study of spinosad in/on tomato was carried out in the field of IARI, New Delhi.

Increasing the amount of percolating water from 20 mL(equivalent to 51.92 mm rainfall) to 160 mL (equivalent to 415.42 mm rainfall) increased the downward mobility of flubendiamide. Major portion of the soil applied formulation of flubendiamide (67.22%) was recovered from the top 0-5 cm soil layer after passing 160 mL water. After percolating 160 mL of water (equivalent to 415.42 mm rainfall) analytical grade flubendiamide leached down upto 15-20 cm depth and 68.06% of the applied insecticide was retained in the top 5-10 cm layer. Metabolite desiodo flubendiamide was detected in 20-25 cm...
