Abstract

The invention discloses 2-pyridine-oxyl(sulfide) benzoyloxy enoates compound with general formula(I, II); wherein X is H or S; R1 is H, halogen, or 4,6- dimethoxy pyrimidine-2- radicel or one of the following groups; methyls on N-O bonds and double bonds are in maleinoid form or anti form; R2,R3,R4,R6,R7 are selected from H or alkyl from C1-C6; R5 is alkyl from C1-C6, alcoxyl-alkyl from C2-C6, alkenyl from C3-C6 or alkynyl from C3-C6; radicals of R6 and R7 are in maleinoid form or anti form; R8 is alkyl from C1-C6, alkenyl from C3-C6 or alkynyl from C3-C6. The compound (I, II)is of activity in weeding and is safe to crops like soybean, cotton, earthnut, cole, corn, etc.

Description

technical field The invention belongs to the field of herbicides, and in particular relates to a 2-pyrimidinyloxy (thio) benzoyl enoate compound and an application thereof. Background technique Due to the succession and change of weed populations and the emergence and rapid development of resistance to chemical pesticides, people's awareness of ecological environment protection has been continuously strengthened. The emphasis on the issue of whereabouts continues to increase. With the gradual reduction of the world's arable land, the continuous growth of the population and the increase in the demand for food, people are forced to rapidly develop agricultural production technology, improve and improve the farming system, and need to continuously invent new and improved herbicidal compounds and compositions. EP223406 reported that certain 2-pyrimidinyloxy (thio) benzoate compounds have herbicidal activity and are safe to peanuts and sunflowers. CN1749236A and CN1927811A dis...
