<p>HERBICIDE COMPOSITIONS OF EXTENDED SOIL SOIL LIFE Herbicidally active thiolcarbamates are employed in combination with certain allyl amine salts of thiocarbamic acid oompounds having the formula < IMG > wherein R4 and R5 are independently selected from the group consisting of allyl, alkyl substituted allyl, and lower alkyl groups having from about 1 to about 6 carbon atoms; R6 and R7 are independently selected from the group consisting of allyl, alkyl substituted allyl, and lower alkyl groups having from about 1 to about 6 carbon atoms; and X is oxygen or sulfur wherein at least one of R4 and R5 and at least one of R6 and R7 is an allyl group. In a typical application, the allyl amine salt of thiocarbamic acid compound is included in sufficient quantity to lessen the rate of soil degradation of the thiolcarbamate. As a result, the herbicidal effectiveness of the thiolcarbamate is enhanced and prolonged, rendering single application of the herbicide effective over a longer period of time.</p> |
