摘要:
There are described compounds exerting an antidotal activity belonging to the classes of the 2-thiazolines-2-substituted and 2-oxazolines-2-substituted, useful in the defense of agrarian cultivations from the toxic action of non-selective herbicides. Utilization and preparation methods thereof are described as well.
