Problems solved by technology

[0004] However, the types and formulations of herbicides used for chemical control of weeds in sugarcane fields are seriously outdated. The majority of sugarcane farmers use the same herbicide for weeding operations for a long time. Due to the increase in weed resistance year by year, the dosage of sugarcane herbicides has increased rapidly. The same herbicide products with different contents and ratios are constantly on the market, so that the ideal method of chemical weeding in sugarcane fields gradually loses its advantages, resulting in the growth of weeds and a huge loss of sugarcane yield
Moreover, due to the continuous expansion of the planting area of ​​high-yield and high-sugar varieties of sugarcane, these high-sugar varieties are extremely sensitive to herbicide products commonly used in sugarcane, especially products containing 2-methyl-4-chloride sodium, atrazine, and diuron. Promote apps on it
At present, there is no suitable herbicide product for high-sugar sugarcane varieties

Abstract

The invention discloses a herbicide composition suitable for cornfields and sugarcane fields, which consists of methoxam, flupyridazen-methyl and fenmetrazone. The composition is safe to corn and sugar cane, can reduce the dosage of herbicide per unit area, improve the herbicide effect and reduce the drug cost. The composition can be formulated into emulsifiable concentrate, microemulsion, suspension concentrate, dispersible oil suspension concentrate, wettable powder or water dispersible granule, and is used for controlling annual weeds in cornfields and sugarcane fields.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a herbicide composition suitable for cornfields and sugarcane fields, a preparation method and application thereof. Background technique [0002] Herbicides reduce human labor to a certain extent. In recent years, herbicides have been widely used in corn fields and sugarcane fields in my country. [0003] However, for corn herbicides, herbicide poisoning occurs to varying degrees every year, especially since this year, this phenomenon has been on the rise, not only causing a decrease in corn yields, but even serious crop failures. It has been reported that nicosulfuron, sodium 2-methyl-4-chloride, and acetochlor have phytotoxicity on corn. Therefore, one of the key factors to ensure the safe cultivation of corn is the scientific use of herbicides. [0004] However, the types and formulations of herbicides used for chemical control of weeds in sugarcane fields are seriously o...
