Eight insecticide treatments, viz monocrotophos 36 SL, chlorpyriphos 20 EC, triazophos 40 EC, imidacloprid 200 SL, endosulfan 35 EC, Quinalphos 25 EC, methyl parathion 50 EC and cartap hydrochloride 4 G were evaluated for their efficacy against rice leaf folder Cnaphalocrocs medinalis (Guenee), yellow stem borer Scirpophaga incertulas (Walker) and whitebacked planthopper Sogatella furcifera (Horva

Imazethapyr, a selective herbicide belonging to imidazole group is used as pre and post emergence to control grasses and broadleaf weeds. Herbicides when applied post-emergence may also leave residues in plant material and soil, depending on the chemical structure, doses and their interaction with the soil properties.

Field experiments were conducted from 2001-2004 to develop management strategies for painted bug, Bagrada hilaris (Burm.) inflicting injury to mustard (Brassica juncea) at seedling stage grown in sandy loam soil of arid Rajasthan.

This study was carried out as an on-farm research for development and validation of IPM module in participatory mode by involving scientists, pesticide industry and farmers.

This article deals with the investigations to study the comparative efficacy of certain indigenous plants oils viz, castor, eucalyptus, sunflower and neem for safe storage of pigeonpea seeds against C. chinensis under laboratory conditions.

This paper reports the extraction and evaluation of marigold essential oil for its insect antifeedant activity.

The antagonistic potential of seventeen fungal isolates (15 Trichoderma harzianum and 2 Fusarium solani isolates) indigenous to the western Himalayan region of India, was evaluated in vitro and in glasshouse against two important stages (sclerotia and mycelium) in the infection cycle of three plant pathogens (Rhizoctonia solani, Sclerotina sclerotiorum and Sclerotium rolfsii).

A field experiment conducted at the College of Agriculture, CSKHPKV, Palampur, H.P. during 1999-2000 revealed that the synthetic pyrethroid treatments viz., deltamethrin, cypermethrin and fenvalerate gave significantly less fruit infestation of cucurbit fruit fly, Bactrocera cucurbitae Coq. upto 14 days of spray on summer squash compared to malathion.

Studies were conducted on the occurence of metabolic mediated resistance in cotton aphid, Aphis gossypil to selected insecticides viz., endosulfan, monocrotophos, dimethoate, phosphamidon, carbaryl and cypermethrin using synergist TPP suppressible metabolic resistance even at 1:5 ratio in respect of monocrotophos and cypermethrin.

Studied were conducted to monitor the terminal pesticide residues in unpolished, polished and parboiled rice. Fifteen rice varieties were collected from Regional Agricultural Research Station (RARS), Titabar of Assam Agricultural University during 2002. Each variety was tested in terms of unpolished, polished and parboiled form, for the presence of pesticide residues.
