Abstract

The invention discloses a herbicide for controlling weeds in zoysia japonica and belongs to the technical field of pesticide herbicides. The herbicide comprises flazasulfuron and mesosulfuron, and the weight ratio of flazasulfuron to mesosulfuron is (1-60):(1-60). Flazasulfuron and mesosulfuron are compounded, the weeding effect is good, the herbicide is safe to the zoysia japonica, the gain function is high, the weed killing spectrum is wide, the prevention effect on broad leaf weeds can be enhanced, and the effect is faster and better. Meanwhile, compared with an existing single agent, the fast-acting property is improved; compared with a single agent, the two effective ingredients are compounded together, the synergistic effect is achieved, due to the fact that the two ingredients are different in action mechanism, the two ingredients have no cross resistance, the application amount of the pesticide is reduced, and pollution to the environment is relieved.

Description

technical field [0001] The invention relates to the technical field of pesticide herbicides, in particular to a herbicide for controlling weeds in zoysia weeds. Background technique [0002] Rubisulfuron-methyl is a contact-type selective herbicide. Under the condition of light, in the process of chlorophyll biosynthesis, it can cause the accumulation of toxic intermediates by inhibiting protoporphyrinogen oxidase, thereby destroying the cell membrane of weeds. Leaves quickly dry and die. Fluasulfuron-methyl was absorbed by plant leaves within 15 minutes after spraying, and it was not affected by rain. Weeds showed poisoning symptoms after 3-4 hours and died within 2-4 days. Rubisulfuron-methyl is mainly used to control broad-leaved weeds and sedges such as pig scorpion, wild sesame, popona, velvetleum, flat storage, Chenopodium, red heart Chenopodium, empty tube morning glory, ferret petal flower, sorrel leaf Polygonum, Weeds such as Polygonum sativa, Polygonum curliculus...
