Abstract

The present invention generally relates to the use of synergistic amounts of Bacillus thuringiensis subsp. kurstaki and chlorantraniliprole for the control of Diamondback Moth, Beet Armyworm, Sugarcane Borer, Soybean Looper and Corn Earworm. Specifically, the synergistic ratio of Bacillus thuringiensis subsp. kurstaki to chlorantraniliprole is from about 1:0.001 to about 1:3.

First claim

The invention claimed is:

1. A method of controlling a crop plant pest selected from the group consisting of Diamondback moth ( Plutella xylostella ), Beet armyworm ( Spodoptera exigua ), Sugarcane borer ( Diatraea saccharalis ), and Corn earworm ( Helicoverpa zea ) comprising applying a pesticidally effective amount of Bacillus thuringiensis subsp. kurstaki and chlorantraniliprole to a plant, wherein Bacillus thuringiensis subsp. kurstaki and chlorantraniliprole are applied at a weight ratio of about 1:0.001.

2. The method of claim 1 wherein the effective amount of Bacillus thuringiensis subsp. kurstaki is from about 50 to about 4,500 grams per hectare.

3. The method of claim 2 wherein the effective amount of Bacillus thuringiensis subsp. kurstaki is from about 100 to about 1,300 grams per hectare.

4. The method of claim 3 wherein the effective amount of Bacillus thuringiensis subsp. kurstaki is from about 150 to about 1,250 grams per hectare.

5. The method of claim 1 wherein the effective amount of chlorantraniliprole is from about 20 to about 150 grams per hectare.

6. The method of claim 5 wherein the effective amount of chlorantraniliprole is from about 30 to about 130 grams per hectare.

7. The method of claim 6 wherein the effective amount of chlorantraniliprole is from about 50 to about 110 grams per hectare.

8. The method of claim 1 wherein the crop plant pest is Diamondback moth ( Plutella xylostella ).

9. The method of claim 1 wherein the crop plant pest is Beet armyworm ( Spodoptera exigua ).

10. The method of claim 1 wherein the crop plant pest is Sugarcane borer ( Diatraea saccharalis ).

11. The method of claim 1 wherein the crop plant pest is Soybean looper ( Chrysodeixis includens ).

12. The method of claim 1 wherein the crop plant pest is Corn earworm ( Helicoverpa zea ).

13. The method of claim 1 wherein the plant is selected from the group consisting of crop plants producing 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.

14. The method of claim 13 wherein the plant is genetically modified.

15. The method of claim 13 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.

16. The method of claim 15 wherein the plant is genetically modified corn.

17. The method of claim 13 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.

18. The method of claim 17 wherein the plant is genetically modified soybean.

19. A method of controlling Soybean looper ( Chrysodeixis includens ), comprising applying a pesticidally effective amount of Bacillus thuringiensis subsp. kurstaki and chlorantraniliprole to a plant, wherein Bacillus thuringiensis subsp. kurstaki and chlorantraniliprole are applied at a weight ratio of about 1:0.08.
