Rice Pest Pheno - Forecasting
Portal
Though sporadic in occurrence, this pest causes heavy losses during sudden outbreaks. Serious infestations have been reported from Bihar, Uttar Pradesh, Orissa and Madhya Pradesh.
The pest survives mainly on rice and other related weeds such as Echinochloa colonum and Eleusine coracana during the early part of the season. Damage by cut worms remains unnoticed in the early stages of pest infestation and often leads to a serious situation at crop maturity.
The larvae cut the earheads in addition to damaging the foliage. When the pest population reaches high, there is excessive feeding and complete removal of whole leaves and plants. The rice panicles are cut off from the base, sometimes leading to complete loss of the crop.
In case of sudden infestation spray Chlorpyrophos 20 EC @ 500 ml per acre in the evening hours.
