Management and cultural practices

1. Split nitrogen fertilizer application. Apply nitrogen fertilizer during seedling, tillering, and panicle initiation. Heavy infestation occurs with high doses of nitrogenous fertilizer. Do not apply too much nitrogen in your field and not more than in those of your neighbors. The moths are attracted to the green plants (Khan; et. al., 1988: pp. 129-174).
2. Practice proper sanitation. Clean border areas from weeds and grasses. They serve as alternate host.
3. Monitor for crickets. They are good predators of leaffolder eggs (Reissig; et. al., 1986: pp. 119 -127).
4. During the first 30 days after transplanting or 40 days after sowing, it is advisable not to control leaffolders as they will not cause significant economic loss. The rice crop can compensate from the damage when water and fertilizer are well managed (Reissig; et. al., 1986: pp. 119 -127).
5. Practice crop rotation such as planting leguminous crops after the rice harvest.
6. Avoid ratooning. The pupae might still be in the plant.
7. In irrigated rice fields, plow-in rice stubbles and other plant residues, then subsequently flood the field.
