ABSTRACT OF THE DISCLOSURE There are described compounds exerting an antidotal activity belonging to the classes of the 2-thiazolines-2-substi- tuted and 2-oxazolines-2-substituted, useful in the defence of agrarian cultivations from the toxic action of non-selective her- bicides. Such compounds have the formula Image (I) wherein Y is an alkyl C1-C4 substituted by one or more halogen atoms selected from the group consisting of Cl, Br and F; R1, R2, R3 and R4, like or unlike one another, are hydrogen or an alkyl C1-C4. The compounds are endowed with an antidotal action towards non-selective herbicides in important agrarian cultivations. Furthermore, the invention relates to a method of defending agrarian cultivations from the toxic action of non- selective herbicides, consisting in administering the captioned compounds to the cultivations, and to the compositions of agrarian use containing said compounds.
