1. Broadening herbicide spectrum: The chemical composition, structure and physicochemical properties of various herbicides are different, that is, the ability and range of herbicides of various herbicides are not exactly the same. In general, the combination of herbicides can often increase the scope of weeding. For example, the atrazine-acetochlor mixture widely used in corn fields can effectively control broad-leaved weeds and part-time grass weeds.
2. Improve the herbicidal effect: Synergistic herbicide mixed formulations are mostly composed of different types of herbicides. Using synergistic effects of herbicides can increase weeding efficacy, reduce the amount of pesticides per unit area, and reduce the cost of medication.
3. Extended application period: When two or more herbicides that have control effects on weeds at different growth stages are used, the application period may be prolonged. For example, the combination of acetochlor and nicosulfuron can effectively prevent unearthed and unearthed weeds, and can be used before and after seedling emergence.
4. Reducing the phytotoxicity to crops: Many herbicides have poor selectivity between crops and weeds. If they are not paid attention, they may cause phytotoxicity to crops and increase their selectivity between crops and weeds. Improve crop safety. For example, if fluoxetine is used alone in soybean fields, it is easily absorbed by beans due to its high water solubility, and mixed with trifluralin can increase the herbicidal effect while also avoiding the effects of oxathione on soybeans. Phytotoxicity.
5. Reducing residual toxicity: For example, atrazine is an excellent herbicide in corn fields. It is safe for corn and has a good effect on most weeds. However, due to its long residue period, it will have an impact on the crops of the next crop. The combination of acetochlor and the like can reduce the use of atrazine and significantly reduce the phytotoxicity of the crops on the bottom.
6. Delaying the development and development of drug resistance: Mixing herbicides is the most basic method for effectively preventing, delaying and controlling weed resistance. The use of a certain percentage of mixed herbicides can significantly reduce the frequency of emergence of drug-resistant weeds, thereby reducing the occurrence and development of herbicide resistance.
7. The effect of increasing production is significant: weeds have a particularly serious impact on crops. When they occur seriously, they can cause crops to reduce production. Therefore, controlling weeds and crops to win light, water, and fertilizer can improve grain quality, increase yield and quality, and thus increase production.
