Features

Effective against Diamondback Moths, Cabbage Caterpillars, Cabbage Loopers, Armyworms, Beet Armyworms, Cotton Bollworms, Corn Earworms, Tomato Leafminers, Fruit Borers, Leafrollers, Webworms, and other lepidopteran larvae.

After ingestion by larvae, Btk crystal proteins act on the insect midgut, disrupting gut membranes, stopping feeding, and causing larval death.

Mainly suitable for cabbage, broccoli, cauliflower, tomato, pepper, cucumber, melon, corn, cotton, soybean, peanut, rice, apple, grape, citrus, tea, tobacco, ornamentals, and forestry crops where locally registered

Application Guide

Application Crops	Target Pests	Recommended Application Rate	Application Timing
Vegetable Crops
Cabbage, Broccoli, Cauliflower, Chinese Cabbage, Lettuce, Tomato, Pepper, Eggplant, Cucumber	Diamondback Moths, Cabbage Caterpillars, Cabbage Loopers, Beet Armyworms, Webworms, Leaf-eating Caterpillars, Tomato Leafminers, Melonworms, Leafrollers	500–1,200 g/ha	Apply at egg hatch or early larval stage. Best results are achieved on young larvae before severe leaf damage occurs.
Field Crops
Corn, Cotton, Soybean, Peanut, Rice	Corn Earworms, Corn Borers, Fall Armyworms, Cotton Bollworms, Tobacco Budworms, Soybean Loopers, Armyworms, Rice Leafrollers, Stem Borers Before Boring	600–1,500 g/ha	2
Fruit Crops
Apple, Pear, Grape, Citrus, Peach, Mango, Pomegranate	Leafrollers, Codling Moths, Oriental Fruit Moths, Fruit Borers, Citrus Cutworms, Webworms, Tent Caterpillars, Lepidopteran Larvae	600–1,500 g/ha	Apply based on pest monitoring, egg hatch, or early larval activity. Ensure good canopy coverage because larvae must ingest treated foliage or fruit surfaces.
Cash Crops / Ornamentals / Forestry
Tea, Tobacco, Ornamentals, Nursery Crops, Forestry Trees	Tea Caterpillars, Tea Loopers, Tobacco Budworms, Cutworms, Armyworms, Leafrollers, Webworms, Tent Caterpillars, Forest Defoliating Caterpillars	800–2,000 g/ha	Apply at the early larval stage. For forestry or high-canopy crops, use sufficient spray volume to obtain uniform coverage of feeding sites.
