Field experiment was conducted to study the persistence of pretilachlor in soil and its residues in post harvest straw and grain.

Field trials were conducted for the validation of integrated pest management (IPM) package for the castor and pigeonpea intercropping system in rainfed agro-ecosystem for the state of Andhra Pradesh, India during 2002 and 2003 seasons.

Thirty genotypes of sesame seeds collected from different geographical regions of India were analyzed for organochlorine pesticides viz HCHs, DDTs and endosulfan.

In the light of increased awareness on unwanted effects of conventional insecticides and concern for ecofriendly plant protection, avermectins have emerged as new group of insecticides.

Dissipation of chlorpyriphos on cauliflower was studied following applications at recommended dose and double dose for the two consecutive years 2004 and 2005 to work out the safe preharvest waiting period.

The degradation of insecticides chlorpyrifos, fipronil, endosulfan, cyhalothrin and deltamethrin at 5-10 mg kg in wheat grains during storage and processing was investigated.

Wider area validation and economic analysis of adaptable IPM technology in egg plant Solanum melongena L. in a farmers' participatory approach was carried out in adopted villages Raispur and Harsawan, Ghaziabad District, UP during 2003-04, 2004-05 and 2005-06 in an area of 30 acres covering 30 farming families.

A field experiment was conducted during kharif 2007 in the vegetable farm of the Division of Entomology, IARI, New Delhi in Randomized Block Design with ten treatments including a control. Seed treated with imidacloprid (3 g ai kg-1 seeds) or foliar spray either of thiamethoxam/acetamiprid/imidacloprid @20 g ai ha-1 effectively reduced leafhopper population, Amrasca biguttula.

The efficacy of carbosulfan was evaluated during kharif, 2005-06 against rice stem borer, Scripophaga incertulas in comparison with chlorpyriphos. The results revealed that all the insecticidal treatments reduced the insect population significantly over untreated control and incurred significantly higher yield.

Three application of diafenthiuron at normal (600 g ai ha-1) and double the normal dose (1200 g ai ha-1) were made at 21 days interval during 2 season field trials.
