Technical Field

The invention relates to the technical field of agriculture, and particularly relates to a herbicide composition.

Background

In agricultural production, undesirable vegetation (weeds) can develop seriously, endangering the growth of target crops such as crops, forest trees and the like, and affecting the normal use of undesirable vegetation plots (e.g., uncultivated areas, railways, highways, forest fire-protection tunnels, industrial sites, yards and the like). Herbicides are the most economical, fast and effective method for controlling unwanted plants.

The single herbicide is easy to generate drug resistance or has a limited control spectrum when used, and the harm of plants in the actual production can not be well solved.

Quinclorac is a specific selective herbicide for preventing and killing barnyard grass in paddy fields, belongs to hormone quinoline carboxylic acid herbicides, has similar weed poisoning symptoms to auxin effects, is mainly used for preventing and treating barnyard grass, and has long working life which is effective in 1-7 leaf periods. The rice has good safety.

Atrazine is a systemic selective pre-and post-emergence herbicide. Root absorption is dominant, and stem and leaf absorption is less. The weeding effect and selectivity are the same as those of simazine, and the weeding composition is easy to drip to deeper soil by rainwater, is also effective to some deep-rooted weeds, but is easy to generate phytotoxicity. The lasting period is also longer. It has wide herbicidal spectrum and can prevent and kill several annual gramineous and broad-leaved weeds. The herbicide is suitable for preventing and killing weeds of crabgrass, barnyard grass, green bristlegrass, nutgrass flatsedge, alopecurus, polygonum, chenopodium album, cruciferae and leguminous plants such as corn, sorghum, sugarcane, fruit trees, nursery gardens, woodlands and the like, has good selectivity on corn (because a detoxification mechanism exists in the corn body), and also has a certain inhibition effect on certain perennial weeds.

Fluroxypyr-meptyl (standing) fluroxypyr-meptyl belongs to a systemic conduction type post-emergence stem and leaf treatment herbicide, is quickly absorbed by weeds after application, enables sensitive plants to have the reaction of typical hormone herbicides and conduct to all parts of the whole plant, enables the plants to be deformed and distorted, and finally dies. The weeding composition is suitable for preventing and killing broadleaf weeds in wheat, barley, corn, grapes, orchards, pastures, forest lands, lawns and the like; such as cleavers, polygonum convolvulus, purslane, black nightshade, bindweed, polygonum, amaranth and the like, and is ineffective to gramineous weeds. The method is characterized in that: 1. can prevent and kill various broad-leaved weeds such as cleavers, polygonum convolvulus, purslane, black nightshade, chickweed, vetch, bindweed, weasel flower, polygonum cuspidatum, polygonum hydropiper, amaranthus retroflexus, dayflower, elsholtzia, Thalathus, vetch, descurainia sophia and Convolvulus arvensis, and is ineffective for gramineae and cyperaceae weeds. 2. Is safe to crops, and in the body of drug-resistant crops, the talarone can be combined with the conjugate to lose toxicity. 3. The compound herbicide is easy to degrade in soil, has short half-life period and cannot cause phytotoxicity to succeeding crops (but data show that the application of the tyluron and the tribenuron-methyl to prevent and control weeds in wheat fields is unsafe to the following broadleaf crops such as cotton, soybean, peanut, pepper and the like).
