Abstract
Derivatives of 2-imino-1,3-dithiolane, 1,3-dithiole, 1,3-dithiane, 1,3-dithietane and 1,3-oxathiole have been found to reduce herbicidal injury to crop plants due to thiocarbamate and acetanilide herbicides.
Claims26
A method of reducing injury to crop plants selected from the group consisting of rice, sorghum and wheat due to the application thereto of thiocarbamate herbicides which comprises applying to the plant locus a safening effective amount of a compound having the formula ##STR53## or an agriculturally acceptable acid addition salt thereof, wherein R is ##STR54## R.sub.1 is hydrogen or lower alkyl;
- X and Y independently equal hydrogen, lower alkyl, lower alkoxy or halogen;
- n is 0, 1, 2 or 3;
- provided that when n is 1 R.sub.1 cannot equal ethyl.
A mixture which comprises a herbicidally effective amount of a thiolcarbamate herbicide and a safening effective amount of a compound of the formula ##STR60## or an agriculturally acceptable acid addition salt thereof, wherein R.sub.5 ##STR61## R.sub.1 is hydrogen or lower alkyl;
- X and Y independently equal hydrogen, lower alkyl, lower alkoxy or halogen;
- n is 0, 1, 2 or 3;
- provided that when n is 1 R.sub.1 cannot equal ethyl.
