Problems solved by technology

Temperature has no effect on the final effect of weeding, but affects the speed of its efficacy
Generally, when the temperature is low, the drug effect is slow, and the plant will stop growing after poisoning, but it will not die immediately; the plant will die soon after the temperature rises.

Abstract

The invention provides a safe and phytotoxicity-free herbicide composition and combined application of the same and a pesticide for simultaneous killing of weeds and pests. The herbicide composition contains fluroxypyr or fluroxypyr-mepthyl, mesotrione and atrazine, wherein a weight ratio of fluroxypyr or fluroxypyr-mepthyl to mesotrione to atrazine is 0.1-10: 0.1-10: 0.1-40. The composition can be prepared to form a dispersable oil suspension. The pesticide comprises preparations and a compound preparation of triflumuron and diflubenzuron. The herbicide composition and the pesticide are used together for preventing and treating annual and perennial gramineous plants and broad-leaf weeds and pests like corn borers, armyworms, termites, mole crickets and wireworms in a corn field.

Description

technical field [0001] The present invention relates to a safe and harmless pesticide herbicide composition and its combined application with insecticides, which not only kills weeds but also kills insects, and more particularly relates to a compound containing fluroxypyr or fluroxypyr isocyanate Composition of octyl ester, mesotrione, atrazine, triflubenzuron or diflubenzuron and application thereof for controlling annual and perennial grasses and broad-leaved weeds, corn borers, armyworms, and termites in cornfields , mole crickets, day lily worms and other pests. Background technique [0002] fluroxypyr (4-amino-3,5-dichloro-6-fluoro-pyridine-2-oxyacetic acid) or isooctyl fluroxypyr (4-amino-3,5-dichloro-6 -Fluoro-pyridine-2-oxo-octyl acetate) belongs to pyridine systemic conduction type post-emergence herbicide. After the drug is quickly absorbed by the plants, the sensitive plants will respond to typical hormone herbicides, and the plants will be deformed and twisted....
