Description

Herbicidal composition containing isoxaflutole and imazapic and application thereof
Technical Field
The invention relates to a weeding composition, in particular to a weeding composition with isoxaflutole and imazapic as active pharmaceutical ingredients and application of the weeding composition in preventing and removing weeds in a sugarcane field, and belongs to the technical field of pesticides.
Background
An isoxazole herbicide of isoxaflutole is an organic heterocyclic selective systemic pre-emergence herbicide used for soil treatment in dry crop fields such as sugarcane, corn and the like, and mainly acts through the absorption and conduction of young roots of weeds. After the sensitive weeds are absorbed, the chlorophyll formation is destroyed by inhibiting the p-hydroxyacetone dioxygenase, so that the damaged weeds lose green and wither. When or after the isoxaflutole is applied, effective components remained in surface soil due to poor soil moisture content cannot timely play a role in preventing and removing weeds, but can still be kept for a long time without being decomposed, and the active components can still play a role in preventing and removing weeds even in case of rainfall or irrigation, and can kill and inhibit sensitive weeds growing to 4-5 leaves.
The action mechanism of the imazapyr belongs to an imidazolinone herbicide is as follows: inhibitors of acetolactate synthase (ALS) or acetohydroxy-Acid Synthase (AHAs), drugs are absorbed through roots, stems, leaves and conducted in xylem and phloem, accumulated in plant meristems, inhibit acetolactate synthase of plants, prevent biosynthesis of branched-chain amino acids such as valine, leucine, isoleucine, thereby disrupting protein synthesis, interfering with DNA synthesis and cell division and growth, and ultimately causing plant death. The imazapic is mainly used for preventing and killing most of broadleaf weeds, annual gramineous weeds and cyperaceae weeds in sugarcane fields and peanut fields.
When the isoxaflutole is used alone, the safety to crops is poor; the imazapic has a common weed death rate when preventing and removing weeds, the effect is mainly reflected in inhibition and has a long residual period, and economic crops such as beet, vegetables, rape and the like are not suitable to be planted in the next crop, and the imazapic also has influence on grain crops such as rice, corn, wheat and the like. With the increase of the medicament using time, the defects of weed drug resistance, large dosage and the like exist, the cost is increased, and the environmental pressure is increased. At present, no report on a herbicidal composition compounded by isoxaflutole and imazapic and application thereof is found.
