Composite herbicide containing bensulfuron methyl, pyrazosulfuron methyl and cafenstrole and preparation method thereof

Abstract

The invention discloses a composite herbicide containing bensulfuron methyl, pyrazosulfuron methyl and cafenstrole and a preparation method thereof, relates to the technical field of composite herbicides, and aims to solve the problems that the existing composite herbicide has a poor effect of removing perennial broad-leaf weeds, underground organs of the broad-leaf weeds are easy to survive and remain, the range of the herbicide is small, and the herbicide is difficult to use. And large-range weed killing is not facilitated. Comprising the following components in percentage by mass: 25-40% of bensulfuron methyl; 20%-30% of pyrazosulfuron-ethyl; 15%-35% of cafenstrole; 10%-25% of mole cricket attractant; 5%-10% of a surfactant; the mole cricket attractant is prepared from plant volatile substances, cane sugar and a flavoring agent, the plant volatile substances are one or more of alcohol compounds, terpenoids, aromatic compounds, ketone compounds and hydrocarbon compounds, and the flavoring agent is one or more of the alcohol compounds, the terpenoids, the aromatic compounds, the ketone compounds and the hydrocarbon compounds. The flavoring agent is one or more of wheat seedlings, grain seedlings, corn, sorghum, vegetable leaves and melon and fruit peels which are mixed and granulated.

Description

technical field [0001] The invention relates to the technical field of compound herbicides, in particular to a compound herbicide containing bensulfuron-methyl, pyrazosulfuron-methyl and mefentrazone and a preparation method thereof. Background technique [0002] Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, a class of substances used to eliminate or inhibit plant growth. [0003] However, the existing compound herbicides are relatively poor in removing perennial broad-leaved weeds, and the underground organs of broad-leaved weeds are likely to survive and remain, and the range of the herbicide itself is small, which is not conducive to killing large-scale weeds; therefore , does not meet the existing needs, and we propose a compound herbicide containing bensulfuron-methyl, pyrazosulfuron-methyl and metenzalam and a preparation method thereof. Contents of the invention [0004] The object of the present invention is to...
