Hydrophilic polymers have been prepared by grafting synthetic monomers on starch, a naturally occuring polysaccharide polymer for improving the water absorption and delaying its loss. Some polymers based on carboxymethyl cellulose developed recently have shown nearly 33000% m/m water absorption. These hydrogels can be used in diverse areas of agriculture such as dryland/rainfed agriculture, hi-tech horticulture and floriculture, nursery raising in soil less media, soil reclamation, agroforestry, artificial lawns and landscapes, terrace gardening etc.
Synthetic pesticides, neem emulsifiable concentrate (EW), Azadirachtin-A concentrate, neem oil microemulsion/microemulsion forming concentrate and processes of making dihydroazadirachtin-A concentrate under ambient conditions have been developed
A process for preparing an herbicidal composition comprising of neem leaves extract for the control of Phalaris minor weed without affecting the growth of wheat has also been developed
Natural and synthetic polymers, either alone or in combination with inorganic inert have been successfully developed as seed coats. Such coats have been developed employing botanical active ingredients ex. neem meliacins etc. Seed coats based on botanical pesticide will help in improving germination, viability, plantability of a seed or vigour of an agronomic plant that is grown from a treated seed that is planted in a pest infested location, by preventing the fungal/nematode/insect infestation that is a pest for the agronomic plant and against which a meliacin compound has bioactivity
Neem oil coated urea (NOCU), Pusaneem GOlden urea and Neem bitter coated urea has been developed. Field efficacy established on rice showed yield increase from 7-17%
Dillapoile, an undesirable constituent present on the tune of 20-40% in the essential oil of Anethum sowa ROxb., and its dihydro derivative prepared in laboratory have been developed as indigenous substitutes for the imported and internationally recognized synergist piperonyl butoxide (PBO)
Controlled release formulations of phorate have been successfully developed through its monolithic dispersions in polystyrene, polyvinyl chloride, polymethyl-methacrylate, polyethylene glycol and cellulose acetate, ethyl cellulose and starch xanthate. These formulations have been found to provide comparable pest control at one half to one fourth of the phorate content as compared to Thimet 10G, its commercial product
A technology fo rmosquito larvicidal preparations based on Rabdosea melissoides has been developed. The essential oil of r. melissoides and its phenolic and non-phenolic constitutents have been developed as potential mosquito larvicidal products.
Novel pesticidal oxime esters, alkane diol/polyol mono/di/poly alkanoates, 4-methyl-6-pentyl-a-pyrones have been developed as potent wide spectrum pesticidal products. The compounds are effective particularly as nematicides against Meloidogyne incognita and Rotylenchulus reniformis and fungicides against polyphagous fungi Rhizoctonis solani and Sclerotium rolfsi
Cost effective and indigenous know-how for conventional pesticides namely thiophanate-methyl and mancozeb have been developed and passed to NRDC for commercialization.
