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
