Protect Rice crop from insect and diseases

Farmers lose an estimated average of 37% of their rice crop to pests and diseases every year. In addition to good crop management, timely and accurate diagnosis can significantly reduce losses. If you are facing a problem in your crop and need help with diagnosis, seek advice from entomologists and Plant pathologists.Cultural practices are integral part of IPM. Summer ploughing, selection of healthy seeds, timely planting, raising of healthy nursery, removal of weed from field, balanced use of fertilizers as per recommendations are the important cultural practices that are followed for pest management in paddy.Mechanical practices comprise of removal and destruction of pest infested plant parts, clipping of rice seedling tips and collection of egg masses and larvae of pest and their placement in bamboo cages for conservation of biocontrol agents.Biocontrol agents like coccinellids, spiders, damsel flies, dragonflies should be conserved. Chlorpyriphos is used for root dip treatment of rice seedlings. Egg, masses of borers are collected and placed in a bamboo cage cum percher till flowering. It permits the escape of egg parasites and trap and kill the hatching larva.Pheromone traps are installed at the rate of 20 traps/ha to trap yellow stem borer at 10 days after transplanting.Chemical control measures are used under IPM as a last resort. Application of pesticides has to be need based and proper crop health monitoring, observing ETL and conservation of natural biocontrol agents has to be ensured before deciding in favour or use of chemical pesticides.
