Abstract

Herbicidal injury caused by 6-(trisubstituted phenyl)-4-amino-2-pyridinecarboxylates in direct seeded and transplanted paddy rice is reduced with the use of beflubutamid, bispyribac, carfentrazone, cloquintocet, cyhalofop, daimuron, dichlormid, dimepiperate, fenchlorazole, fenclorim, fluxofenim, furilazole, halosulfuron, isoxadifen, mefenpyr, norflurazon, oxabetrinil, pyriclor, sulcotrione, AD67 and mixtures thereof.

Claims

1. A composition for protecting direct seeded and transplanted paddy rice from the harmful effects of a 6-(trisubstituted phenyl)-4-amino-2-pyridinecarboxylate herbicide of the formula (I)

2. The composition of claim 1 in which the 6-(trisubstituted phenyl)-4-amino-2-pyridinecarboxylate herbicide is a 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)-2-pyridinecarboxylic acid derivative or a 4-amino-3-chloro-6-(2,4-dichloro-3-methoxyphenyl)-2-pyridinecarboxylic acid derivative.

3. The composition of claim 1 in which the weight ratio of the 6-(trisubstituted phenyl)-4-amino-2-pyridinecarboxylate herbicide to the safener is between about 1:

8 and about 1;

32.

4. The composition according to claim 1, where the active safener or compatible herbicide capable of safening is bispyribac and wherein the weight ratio of the 6-(trisubstituted phenyl)-4-amino-2-pyridinecarboxylate herbicide to the safener is from about 1:

1 to about 1;

3.2.

5. The composition according to claim 1, where the active safener or compatible herbicide capable of safening is cyhalofop and wherein the weight ratio of the 6-(trisubstituted phenyl)-4-amino-2-pyridinecarboxylate herbicide to the safener is from about 1:

1.3 to about 1;
