Abstract

The present invention relates to herbicide composition of monosulfuron ester compound as well as its application, which is compounded with two-element or three-element from herbicide monosulfuron ester or its natrium salt (0.1 to 90 percent) as main active component, and other herbicide (0.1 to 85 percent) of ethyl carboxylic fluorine grass ether, Starane, thifensulfuron-methyl, tribenuron-methyl, 2,4D as well as its ramification, Prometrex prometryn, acetochlor, atrazine, triallate, metolachlor, bensulfuron-methyl or 2 armour 4 chlorin natrium etc., and the herbicide composition can be made into breast oil, wettable powder, soluble powder, water emulsion, microemulsion agent, aqua, suspending agent, microcapsule agent or water disperse particle agent by adding proper amount auxiliary agent and carrier accepted in agriculture. The composition can be used to prevent single and double cotyledon weed in wheat, corn and millet field.

Description

technical field [0001] The present invention relates to the field of agricultural herbicides, in particular to a compound herbicide composition of monosulfuron ester compounds, including monosulfuron ester compounds and the following herbicides, aciflufen, citriron, and thiophene Promethazine, tribenuron-methyl, 2,4D and its derivatives, promethazone, acetochlor, atrazine, permethazine, avencam, metolachlor, bensulfuron-methyl or 2-methyl-4-chloride sodium, etc. Binary or ternary compound herbicides. Background technique [0002] Chinese patents CN 93101976-1 and CN 94118793.4 respectively disclose that sulfonylurea compounds have excellent herbicidal activity and safety, less dosage, fast degradation rate, less residue, and show greater selectivity in biological activity. Superiority, it can be used for weeding in crop fields. Pre-emergence soil surface spraying, or post-emergence stem and leaf treatment, can effectively control broad-leaved weeds. Monosulfuron ester (mo...
