Synergistic
The present invention generally relates to the use of synergistic amounts of Bacillus thuringiensis subsp. aizawai and chlorantraniliprole for the control of Diamondback Moth, Beet Armyworm, Soybean Looper, Corn Earworm, Cabbage Looper, and Southwestern Corn Borer. Specifically, the synergistic ratio of Bacillus thuringiensis subsp. aizawai to chlorantraniliprole is from about 1:0.00003 to about 1:3.
1. A method of controlling a crop plant pest selected from the group consisting of Plutella spp., Spodoptera spp., Helicoverpa spp., Trichoplusia spp. and Diatraea spp. comprising applying an effective amount of Bacillus thuringiensis subsp. aizawai and chlorantraniliprole to a plant, wherein the ratio of Bacillus thuringiensis subsp. aizawai to chlorantraniliprole is from about 1:0.00003 to about 1:3.
2. The method of claim 1 wherein the ratio of Bacillus thuringiensis subsp. aizawai to chlorantraniliprole is from about 1:0.001 to about 1:1.
3. The method of claim 2 wherein the ratio of Bacillus thuringiensis subsp. aizawai to chlorantraniliprole is from about 1:0.04 to about 1:0.8.
4. The method of claim 1 wherein the effective amount of Bacillus thuringiensis subsp. aizawai is from about 50 to about 4,000 grams per hectare.
5. The method of claim 4 wherein the effective amount of Bacillus thuringiensis subsp. aizawai is from about 100 to about 1,300 grams per hectare.
6. The method of claim 5 wherein the effective amount of Bacillus thuringiensis subsp. aizawai is from about 150 to about 1,250 grams per hectare.
7. The method of claim 1 wherein the effective amount of chlorantraniliprole is from about 20 to about 150 grams per hectare.
8. The method of claim 7 wherein the effective amount of chlorantraniliprole is from about 30 to about 130 grams per hectare.
9. The method of claim 1 wherein the crop plant pest is Plutella spp.
10. The method of claim 1 wherein the crop plant pest is Spodoptera spp.
11. The method of claim 1 wherein the crop plant pest is Chrysodeixis spp.
12. The method of claim 1 wherein the crop plant pest is Helicoverpa spp.
13. The method of claim 1 wherein the crop plant pest is Trichoplusia spp.
14. The method of claim 1 wherein the crop plant pest is Diatraea spp.
15. The method of claim 1 wherein the plant is selected from the group consisting of root and tuber vegetables, bulb vegetables, leafy non-brassica vegetables, leafy brassica vegetables, succulent or dried legumes, fruiting vegetables, cucurbit vegetables, citrus fruits, pome fruits, stone fruits, berry and small fruits, tree nuts, cereal grains, forage and fodder grasses and hay, non-grass animal feeds, herbs, spices, artichoke, asparagus, coffee, cotton, tropical fruits, hops, malanga, peanut, pomegranate, oil seed vegetables, sugarcane, tobacco, and watercress.
16. The method of claim 15 wherein the plant is genetically modified.
17. The method of claim 15 wherein the cereal grains are selected from the group consisting of barley, buckwheat, pearl millet, proso millet, oats, corn, field corn, sweet corn, seed corn, popcorn, rice, rye, sorghum (milo), sorghum species, grain sorghum, sudangrass (seed), teosinte, triticale, wheat, wild rice, and cultivars, varieties and hybrids thereof.
18. The method of claim 17 wherein the plant is genetically modified corn.
19. The method of claim 15 wherein the succulent or dried vegetable legumes are selected from the group consisting of Lupinus beans, Phaseolus beans, Vigna beans, broad beans, chickpea, guar, jackbean, lablab bean, lentil, Pisum peas, pigeon pea, soybean, immature seed soybean, sword bean, peanut, and cultivars, varieties and hybrids thereof.
20. The method of claim 19 wherein the plant is genetically modified soybean.
