Opis

Rice is the source of livelihood for hundreds millions of households around the Globe. Several Asian and African countries are highly dependent on rice as a source of food and foreign exchange as well as government revenue. Global rice production must increase by 36 per cent by 2025 to feed estimated 4 billion rice consumers. But the rice production is limited by both biotic and abiotic stresses of which insect pests alone caused about 25 per cent losses. Rice leaf folder is considered second economically important insect after the stem borer. Of all insect control methods, the planting of pest resistant varieties is the most effective. Biochemical studies will be helpful in confirming the physiological antibiosis of the new germplasm. Weather factors are the major regulating causes for the insect pest populations under field circumstances. Effective crop protection is an integral component of efforts to increase and sustain rice, O. sativa yields. Many national and international organizations and farmer groups are promoting Integrated Pest Management. IPM uses pest-resistant varieties and biochemical bases of resistance and that's why can provide enormous benefits to rice farmers.
