Metolachlor can be mixed with many herbicides and used in dryland crops, vegetable crops and orchards, nurseries. In order to help farmers friends to better understand the knowledge of metolachlor, Xiaobian collected a lot of information. The following is an introduction to the range of use of metolachlor and its use: First, the scope of use Metolachlor is applied to dryland crops, vegetable crops, orchards and nurseries. It can prevent annual grass weeds such as goosegrass, crabgrass, foxtail, cotton grass, and broadleaf weeds such as amaranth and purslane. Mi Sha grass, oil sedge. Metolachlor is mainly absorbed by the shoots and conducts upward, inhibiting the growth of shoots and roots. The mechanism of action mainly inhibits the protein synthesis of the germinating seeds, and secondly inhibits the infiltration of choline into the phospholipids and interferes with the formation of lecithin. Because the ability of grass weeds to absorb metolachlor is stronger than that of broadleaf weeds, the effect of this herb on weed control is far better than that of broadleaf weeds. In addition, metolachlor is also used to: (l) Live sweet pepper, cabbage, radish, radish, Chinese cabbage, Chinese cabbage, rapeseed, watermelon, broccoli and other vegetable fields weeding, after sowing to the emergence of seedlings, 100 grams of 72% emulsifiable concentrate, spray with water Treat the soil. (2) Transplanting vegetable fields, such as cabbage, broccoli, sweet (spicy) pepper, etc. After transplanting the seedlings, 100 g of 72% emulsifiable concentrate is used in the mu, and the water is sprayed with water to treat the soil. Second, the method of use 1 spray with 72% metolachlor EC The amount of medicine used per mu varies depending on the type of vegetable crop. Before the cucumber is planted, or before the seedlings of the beans, onions, etc., use 100% to 200 ml of 72% metolachlor EC, 40 kg of water, and evenly treat the noodles. In tomato field, if it is post-emergence, use 8 to 12 ml of 72% metolachlor EC to evenly treat the noodles; if transplanted, use 72% of metolachlor EC 10 ml, water 2 After 1000 grams, evenly treat the kneading noodles, then transplant the tomato seedlings; if laying the mulch, use 100% of 70% metolachlor emulsifiable concentrate, evenly treat the kneading noodles, and then plant the seedlings. In the pepper field, if applying before the live broadcast, use 72% metolachlor EC 100-150 ml, evenly treat the kneading dough, and mix the soil after application; if it is applied before transplanting or before laying the film, use 72% 100 ml of metolachlor EC, evenly treated with noodles, planted with seedlings or planted with plastic film. In the eggplant field, before transplanting or before laying the film, use 100% of 72% metolachlor EC, evenly treat the noodles, plant the seedlings or plant the seedlings. In the potato field, 140-275 ml of 72% metolachlor EC was used to uniformly treat the noodles before sowing. In the live broadcast of sweet pepper, cabbage, rapeseed, large (small) cabbage, large (small) radish and broccoli seedlings, 100 ml of 72% metolachlor EC was used to evenly treat the noodles. After the sweet (spicy) pepper, broccoli, cabbage, etc. were planted, 100 ml of 72% metolachlor EC was used to uniformly treat the noodles. Before the cabbage was transplanted, 130 ml of 72% metolachlor EC was used to uniformly treat the noodles. Before the broccoli was transplanted, 75 ml of 72% metolachlor EC was used to uniformly treat the noodles. In the leek field, if applied immediately after sowing, use 72% metolachlor EC 100-125 ml to evenly treat the noodles; if the old leek is applied 2 days after the cutting, use 72% metolachlor EC 75 ~ I00 ml, evenly treated the noodles. In the garlic ground, the open field or the mulch film are applied within 3 days after sowing, the open field is used with 72% metolachlor emulsifiable concentrate 100-150 ml, and the mulch is used with 75-100 ml of emulsifiable concentrate to uniformly treat the kneading surface. After the celery is sown, the application is carried out, and 100% to 125 ml of 72% metolachlor emulsifiable concentrate is used to uniformly treat the noodles. Watermelon (straight) before sowing, or before transplanting seedlings or after transplanting, evenly treating the noodles with 72% metolachlor EC 100-200 ml, the film covering can reduce the dosage by 20%. Within 3 days after the sowing of ginger, 75-100 ml of 72% metolachlor EC was used to uniformly treat the noodles. 2 mixed spray In order to increase the control effect on broadleaf weeds in potato fields, mix 100-167 parts of 72% metolachlor EC and 20-40 grams of 70% oxazinone wettable powder per acre, after sowing , evenly treat the kneading dough with a mixed solution. 3 with 96% metolachlor EC spray Before the transplanting of the tomato, 130 ml of 96% metolachlor EC was applied per acre, and 30 kg of water was evenly sprayed on the surface, and then the tomato seedlings were planted by the leeches method. Before sowing seedlings such as melons, legumes, and cabbage, use 100% of 96% metolachlor emulsifiable concentrate per acre, and spray 50 kg of water evenly. Cabbage field, sprayed with soil before transplanting, sprayed with 45-60 ml of 96% metolachlor EC per acre.
