Synergistic effect of spinetoram and methoxyfenozide for control of stem borer on rice
A method of protecting rice from infestation and attack by pests comprises contacting rice with a pesticidal composition that comprises a synergistically effective amount of spinetoram and methoxyfenozide. The pesticidal composition comprises methoxyfenozide in an amount of at least three parts by weight per one part by weight of spinetoram.
1. A method of protecting rice from infestation and attack by Chilo suppressalis , the method comprising:
contacting rice with a pesticidal composition to provide a synergistic effect against C. suppressalis , wherein the pesticidal composition comprises spinetoram and methoxyfenozide in a weight ratio of spinetoram to methoxyfenozide of between 1:1 and 1:10.
2. The method of claim 1 , wherein the pesticidal composition comprises spinetoram and methoxyfenozide in a weight ratio of spinetoram to methoxyfenozide of between 1:1 and 1:9.
3. The method of claim 1 , wherein the pesticidal composition comprises spinetoram and methoxyfenozide in a weight ratio of spinetoram to methoxyfenozide of between 1:3 and 1:10.
4. The method of claim 1 , wherein the pesticidal composition comprises spinetoram and methoxyfenozide in a weight ratio of spinetoram to methoxyfenozide of between 1:4.5 and 1:5.5.
5. The method of claim 1 , wherein the pesticidal composition further comprises a phytologically-acceptable inert carrier.
6. The method of claim 1 , wherein the pesticidal composition further comprises an additive selected from a surfactant, a stabilizer, an emetic agent, a disintegrating agent, an antifoaming agent, a wetting agent, a dispersing agent, a binding agent, dye, filler, or combinations thereof.
7. The method of claim 1 , wherein the pesticidal composition comprises spinetoram and methoxyfenozide in a weight ratio of spinetoram to methoxyfenozide of between 1:4.5 and 1:10.
8. The method of claim 7 , wherein the pesticidal composition comprises spinetoram and methoxyfenozide in a weight ratio of spinetoram to methoxyfenozide of between 1:4.5 and 1:9.
9. A method for effectively controlling striped stem borer infestation with a lower dosage rate of methoxyfenozide, the method comprising:
applying methoxyfenozide to an area infested by striped stem borer insects, wherein the methoxyfenozide is applied in conjunction with spinetoram in a weight ratio of spinetoram to methoxyfenozide of between 1:1 and 1:10,
thereby killing at least 90% of the striped stem borer insects in the area.
10. The method according to claim 9 , wherein the methoxyfenozide is applied in conjunction with spinetoram in a weight ratio of spinetoram to methoxyfenozide of between 1:3 and 1:10.
11. The method according to claim 9 , wherein the methoxyfenozide is applied in conjunction with spinetoram in a weight ratio of spinetoram to methoxyfenozide of between 1:4.5 and 1:5.5.
12. The method according to claim 9 , wherein the methoxyfenozide is applied simultaneously with spinetoram in a mixture of the methoxyfenozide and the spinetoram.
13. The method according to claim 9 , wherein the methoxyfenozide is applied in conjunction with spinetoram to an area comprising rice plants.
14. The method according to claim 13 , wherein the methoxyfenozide is applied in conjunction with spinetoram to a rice crop.
15. The method according to claim 9 , wherein the methoxyfenozide is applied in conjunction with spinetoram in an amount of 18 mg/L methoxyfenozide or less.
16. The method according to claim 15 , wherein the methoxyfenozide is applied in conjunction with spinetoram in an amount between 6.67 mg/L and 18 mg/L methoxyfenozide.
