| Abstract: | Eight novel triazinyl phenylthiomethanesulfonyl ureas (2,3) were prepared by reacting phenylthiomethanesulfonamides (1) with 4,6- dichloro - 2 - triazinyl isocyanate using potassium carbonate as catalyst, and then treated further with sodium methoxide in methanol. At 1000g(a.i. )/ha preemergence and 500g(a. i. )/ha postemergence the compound 3d showed 100% and 60% control of Raphanus S L respectively. |
