Vegetable chemical weeding technology

First, celery, carrots, parsley and other umbelliferous vegetable fields: before sowing, 40% herbicide ether per acre 600-650 grams; or 50% chlorpyrifos 100-130 grams; 0% weeding 300 grams of ether plus 50% of the grass and 65 grams of mixed use, 75-100 kilograms of water, spray the soil. It is also possible to combine the preparation of the ground with 50% of Fluorine 150-200 grams per acre before spraying, and spray 75-100 kg of water. After the seeds are applied, the seeds can be sown. If they are germinated, they should be applied 7 days in advance to prevent phytotoxicity. The efficacy lasts for 60-90 days and the effective rate is 90-100%.

Second, eggplant, pepper, tomato, potato and other solanaceous vegetable fields: 1, live broadcast: 25% per acre of amine grass phosphorus emulsifiable concentrate 200 grams; or 40% grass killing net wettable powder 125 grams, 100 kg of water, 5 days to 7 days before transplanting, use 48% of trifluralin per acre, or 200 grams of diltiazem, 50 kg of water, and spray on the ground. Spray at 24 o'clock with a taro or scorpion loose soil 1 cm - 3 cm deep to mix the medicine with the soil. The field can last for 2 months to 3 months. Generally, once the application is applied, the grass growth period can be controlled without the occurrence of grass.

Third, cucumber, pumpkin, melon, watermelon, bitter gourd, gourd and other melons: Cucumber is more sensitive to pesticides, but can use 25% ampicillin emulsion; or 48% dilamine EC, 100-150 g per acre 150-200 kg of water is sprayed on the soil. Other melons are generally applied after transplanting seedlings or after live seeding. Pumpkins and melons must be sprayed on the ground or directional spray on 100 kg of water, with 6-8 leaves and vines 20 cm long, using 48% trifluralin 100 g or 48% cable 200 g. Immediately after the loose soil 1 cm -3 cm deep, the efficiency can be 90-100%, the efficacy can be maintained for 3 months.

4. Cauliflower, cabbage, Chinese cabbage and other cruciferous vegetable fields: after transplanting the seedlings, use 25% herbicide ether wettable powder per acre 500-700 g to water 75-100 kg, directional spray on the surface Or spray 45-100 kg of water with 45% trifluralin 150-200 g; or spray 75-100 kg of water with 50% chlorpyrifos 100 g. After spraying, combined with loose soil 2 cm -3 cm deep, the agent is mixed with the soil, the efficacy can reach 30-40 days, and the effective rate is 95-100%.

5. Vegetable beans, lentils, cowpeas, edamame and other vegetable plots: Before the sowing, use 48% of Fluorin 100 grams of water to 100 kg of water, and spray the soil. The soil is then 1 cm - 3 cm deep and seeded after 3 days. After the seedlings are applied after the sowing, the soil can be sprayed with 50% of the grass and 100 grams of water to 75-100 kg of water, without loosening the soil.

6. Watering vegetables, rapeseed, cabbage, spinach, leeks and other vegetable fields: After sowing seeds and covering fine sand in the vegetable field, use 60% of butachlor 100g per acre for 75-100kg of water, and spray it in 畦Face. To cover straw or thin spray, it can be carried out as usual, with an efficiency of 95-100%.

Seven, note: 1, according to the area of ​​quantitative application, spray evenly, do not leak application, do not re-apply; 2, after application, keep the soil moist, in order to play the drug effect. On windy days, it is not advisable to spray on heavy rainy days. 3. Wash the detergent before use. Wash the different kinds of chemicals before use. Otherwise, it may cause phytotoxicity. 4. Herbicides cannot be mixed with fertilizers or other pesticides. To prevent phytotoxicity. For mixed use, it should be applied after the test; 5, using chemical herbicides to weed, in addition to melons and vegetables, generally still need to loosen the soil to improve the elimination effect and vegetable yield.

Maxacalcitol (22-Oxacalcitriol) is non-calcemic vitamin D3 analog and ligand of VDR-like receptors. IC50 value: Target: Maxacalcitol (22-Oxacalcitriol)suppresses parathyroid hormone (PTH) mRNA expression in vitro and in vivo. Maxacalcitol exhibits similar effects to calcitriol in osteoblast-like cells. Maxacalcitol(22-Oxacalcitriol) inhibits tumor growth of osteosarcoma in vitro in combination with all-trans retinoic acid

Eldecalcitol (ED-71; 2.beta.-(3-Hydroxypropoxy)-1.alpha.,25-dihydroxyvitamin D3) is an analog of 1,25-dihydroxyvitamin D3 that improves bone mineral density. IC50 value: Target: Vd analog Eldecalcitol (ED-71; 2.beta.-(3-Hydroxypropoxy)-1.alpha.,25-dihydroxyvitamin D3) is more efficacious than alfacalcidol in preventing vertebral and wrist fractures in osteoporotic patients with vitamin D sufficiency, with a safety profile similar to alfacalcidol
