PURPOSE:To prolong the period suitable for application, by incoporating a mxture of N-chloroacetyl-N-(2,6-diethylphenyl)-glycine ethyl ester with Simetryne and further 2-methyl-4-chlorophenoxybutyric acid. CONSTITUTION:A herbicide containing N-chloroacetyl-N-(2,6-diethylphenyl)- glycine ethyl ester and Simetryne :2,4-dimethylamino-6-methylthio-1,3,5-triazine which show a powerful control effect on weeds in the germination period and initial growth period and 2-methyl-4-chlorophenoxybutyric acid at a weight ratio in the range of 1-2:1.5:0.8. The herbicide shows a reliable control effect in any period of the growth of weeds about 15-25 days after the rice-planting even in a much smaller amount than in use of simple drugs, and is particularly effective against barnyard grasses in the period of the three to four leaves which have not been easily controlled in the past and further exterminates perennial weeds, e.g. an arrowhead or bulrush, completely. |
