The values of ED50 were obtained for eight of the most promising derivatives of triazine for corn, oats, peas, and beans. According to degree of increase of toxic effect on corn, the tested preparations are arranged in the following order propazin, simazine, atrazine, ipazin, trietazin, khlorazin, atraton, and prometrin. For peas, beans, and oats the most toxic are simazine, atrazine, and propazin prometrin and atraton occupy intermediate places and ipazin and trietazin and especially khlorazin are the least toxic. The first signs of the toxic effect of triazine derivatives are not always the same and are determined by the chemical structure of the herbicide as well as by the peculiarities of the crop in question.
