Claims
- 1. A method of protecting sorghum, rice, soybean and wheat crops from the phytotoxic action of 1,3,5-triazine, haloacetanilide, or pyridyloxyphenoxyacetate or -propionate herbicides, which comprises adding to the herbicide or applying to the locus of the crops, as antidote, a compound of the formula ##STR79## wherein Ar is 1-naphthyl or ##STR80## in which each of R.sub.1 and R.sub.2 is hydrogen, halogen, lower alkyl, lower alkoxy or nitro, and Q is halopropynyl,
- in a plant-protecting amount.
- 2. A method according to claim 1 in which, in the compound,
- Ar is ##STR81## in which R.sub.1 is hydrogen, chlorine or methyl, and R.sub.2 is hydrogen, chlorine, bromine, methyl, methoxy or nitro, and Q is iodopropynyl.
- 3. A method according to claim 1 in which the herbicide is selected from the group consisting of N-(1-methyl-2-methoxyethyl)-N-chloroacetyl-2-ethyl-6-methylaniline, 2,4-bis(isopropylamino)-6-methylthio-s-triazine, 2-ethylamino-4-(1,2-dimethyl-n-propylamino)-6-methylthio-s-triazine and .alpha.-[4-(3,5-dichloropyridyl-2-oxy)-phenoxy]-propionic acid propargylthiolo ester.
- 4. A method according to claim 2 in which the compound is 4-bromophenylacetonitrile-oxime-iodopropynyl ether.
- 5. A method according to claim 4 in which the herbicide is N-(1-methyl-2-methoxyethyl)-N-chloroacetyl-2-ethyl-6-methylaniline and the plant is sorghum.
- 6. A method according to claim 4 in which the herbicide is 2-ethylamino-4-(1,2-dimethyl-n-propylamino)-6-methylthio-s-triazine and the plant is rice.
- 7. A method according to claim 3 in which the compound is para-anisolacetonitrile-oxime-iodopropynyl ether.
- 8. A method according to claim 7 in which the herbicide is 2,4-bis(isopropylamino)-6-methylthio-s-triazine and the plant is soy beans.
- 9. A method according to claim 7 in which the herbicide is .alpha.-[4-(3,5-dichloropyridyl-2-oxy)-phenoxy]-propionic acid propargylthiolo ester and the plant is wheat.
