Eliminate Leaf Folder from Rice crop

Leaf folder caterpillars fold a rice leaf around themselves and attach the leaf margins together with silk strands. They feed inside the folded leaf creating longitudinal white and transparent streaks on the blade, so it is necessary to eliminate leaf folder from rice crop. Hunkar 550 (non-systemic insecticide) is a combination of Chlorpyrifos 50% EC & Cypermethrin 5% EC.

Hunkar 550 (Chlorpyrifos 50% EC & Cypermethrin 5% EC)

• HUNKAR – 550 is a non-systemic insecticide with contact, stomach, and respiratory action.
• HUNKAR – 550 exhibits antifeeding activity.
• HUNKAR – 550 has quick knockdown property.
• HUNKAR – 550 has good residual activity.
• HUNKAR – 550 is safe to the environment and compatible with commonly used pesticides.

Heavy use of fertilizer encourages rapid multiplication of the insect. High humidity and shady areas of the field, as well as the presence of grassy weeds from rice fields and surrounding borders,  favor the development of the pest.

Expanded rice areas with irrigation systems, multiple rice cropping, and insecticide induced resurgences are important factors in the insect’s abundance.

Rice leaf folder occurs in all rice environments and is more abundant during the rainy seasons. They are commonly found in shady areas and areas where rice is heavily fertilized. In tropical rice areas, they are active year-round, whereas in temperate countries they are active from May to October. The adults are nocturnal and during the day, they stay under shade to escape predation. Moths fly short distances when disturbed.

How to prevent leaf folder outbreaks,

• Use resistant varieties. Contact your local agriculture office for an up-to-date list of available varieties.
• Follow rice with a different crop, or a fallow period.
• Avoid ratooning.
• Flood and plow field after harvesting if possible.
• Remove grassy weeds from fields and borders.
• Reduce the density of planting.
• Use balanced fertilizer rates.
• Use Hunkar 550 at a specified dose & instructions.
