Abstract

The present invention generally relates to the use of synergistic amounts of Bacillus thuringiensis subsp. aizawai and Bacillus thuringiensis subsp. kurstaki for the control of diamondback moth, beet armyworm, sugarcane borer, soybean looper, corn earworm, cabbage looper and southwestern corn borer, wherein the ratio of Bacillus thuringiensis subsp. kurstaki to Bacillus thuringiensis subsp. aizawai is from about 1:0.001 to about 1:3.5.

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 ), Soybean looper ( Chrysodeixis includens ), Corn earworm ( Helicoverpa zea ), and Cabbage Looper ( Trichoplusia ni ) comprising applying an effective amount of Bacillus thuringiensis subsp. aizawai and Bacillus thuringiensis subsp. kurstaki to a plant, wherein the ratio of Bacillus thuringiensis subsp. kurstaki to Bacillus thuringiensis subsp. aizawai is from about 1:2.5 to about 1:3.2 when applied to Diamondback moth, Beet armyworm, Sugarcane borer and Cabbage Looper.

2. The method of claim 1 wherein the amount of Bacillus thuringiensis subsp. kurstaki and Bacillus thuringiensis subsp. aizawai is from about 5 to about 400 grams per hectare.

3. The method of claim 1 wherein the amount of Bacillus thuringiensis subsp. kurstaki and Bacillus thuringiensis subsp. aizawai is from about 10 to about 350 grams per hectare.

4. The method of claim 1 wherein the amount of Bacillus thuringiensis subsp. kurstaki and Bacillus thuringiensis subsp. aizawai is from about 25 to about 300 grams per hectare.

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

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

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

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

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

10. The method of claim 1 wherein the crop plant pest is Cabbage Looper ( Trichoplusia ni ).

11. The method of claim 1 wherein the plant is selected from the group consisting of root vegetables, tuber vegetables, bulb vegetables, leafy non- brassica vegetables, leafy brassica vegetables, succulent legumes, dried legumes, fruiting vegetables, cucurbit vegetables, citrus fruits, pome fruits, stone fruits, berry fruits, tree nuts, cereal grains, forage grasses, fodder grasses, herbs, spices, bedding plants, ornamental flowers, and oil seed vegetables.

12. The method of claim 11 wherein the plant is genetically modified.

13. The method of claim 12 wherein the cereal grains are selected from the group consisting of barley, buckwheat, pearl millet, proso millet, oats, corn, rice, rye, sorghum species, sudangrass, teosinte, triticale, wheat, wild rice and hybrids of two or more of the cereal grains.

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

15. The method of claim 11 wherein the succulent or dried legumes are selected from the group consisting of Lupinus beans, Phaseolus beans, Vigna beans, broad beans, chickpea, guar, jackbean, lablab bean, lentil, Pisum sativum , pigeon pea, soybean, sword bean, peanut and hybrids of two or more of the succulent or dried legumes.

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

17. The method of claim 1 wherein the plant is selected from the group consisting of artichoke, asparagus, coffee, cotton, hops, malanga, peanut, pomegranate, sugarcane, tobacco, turf, and watercress.
