Fungicidal composition
View Patent ↗A treatment of N-(phenylethyl)succinamic acid or its salts provides enhancement of fungicide activity of a fungicide azole compound, and thus, a fungicidal composition comprising a fungicide azole compound and N-(phenylethyl)succinamic acid or its salts is effective for controlling plant diseases and may also enhance plant growth.
1. A fungicidal composition comprising 5 to 100 grams of a fungicidal azole compound per 100 kilograms of seed and 0.5 to 99 times by weight the amount of the fungicidal azole compound of at least one compound selected from the group consisting of N-(2-phenylethyl)succinamic acid (PESA) and salts thereof.
2. The fungicidal composition according to claim 1 , wherein the fungicidal azole compound is at least one azole selected from the group consisting of azaconazole, bitertanol, bromuconazole, cyproconazole, difenoconazole, diniconazole, epoxiconazole, fenbuconazole, fluquinconazole, flusilazole, flutriafol, hexaconazole, imazalil, imibenconazole, ipconazole, metconazole, myclobutanil, penconazole, prochloraz, propiconazole, prothioconazole, simeconazole, tebuconazole, tetraconazole, triadimefon, triadimenol, triticonazole, and triflumizole.
3. The fungicidal composition according to claim 1 , wherein the fungicidal azole compound is metconazole.
4. The fungicidal composition according to claim 3 that further comprises clothianidin and metalaxyl.
5. The fungicidal composition according to claim 1 , wherein the amount of the fungicidal azole compound is 0.3 to 30% by weight, and the amount of PESA or its salts is 0.02 to 20% by weight of the fungicidal composition.
6. The fungicidal composition according to claim 1 , comprising 0.3 to 30% by weight of the fungicidal azole compound, 0.02 to 20% by weight of N-(2-phenylethyl)succinamic acid or its salts, 50 to 99.5% of a carrier and 0.25 to 25% by weight of at least one auxiliary for formulation.
7. A method for enhancing fungicidal activity comprising applying the composition of claim 1 to a plant or soil.
8. The method according to claim 7 , wherein the fungicidal azole compound is at least one azole selected from the group consisting of azaconazole, bitertanol, bromuconazole, cyproconazole, difenoconazole, diniconazole, epoxiconazole, fenbuconazole, fluquinconazole, flusilazole, flutriafol, hexaconazole, imazalil, imibenconazole, ipconazole, metconazole, myclobutanil, penconazole, prochloraz, propiconazole, prothioconazole, simeconazole, tebuconazole, tetraconazole, triadimefon, triadimenol, triticonazole, and triflumizole.
9. The method according to claim 7 , wherein the fungicidal azole compound is metconazole.
10. The method of according to claim 9 which further comprises applying clothianidin and metalaxyl.
11. The method according to claim 7 , which comprises applying N-(phenylethyl)succinamic acid or its salts in combination with a fungicide azole compound to seed.
12. The method according to claim 11 , wherein the fungicidal azole compound is at least one azole selected from the group consisting of azaconazole, bitertanol, bromuconazole, cyproconazole, difenoconazole, diniconazole, epoxiconazole, fenbuconazole, fluquinconazole, flusilazole, flutriafol, hexaconazole, imazalil, imibenconazole, ipconazole, metconazole, myclobutanil, penconazole, prochloraz, propiconazole, prothioconazole, simeconazole, tebuconazole, tetraconazole, triadimefon, triadimenol, triticonazole, and triflumizole.
13. The method according to claim 11 , wherein the fungicidal azole compound is metconazole.
14. A method for enhancing plant growth when an azole fungicide is used comprising applying the composition of claim 1 to a plant or soil.
15. The method according to claim 14 , wherein the fungicidal azole compound is triadimenol.
