How to use carbofuran? Which crops can use carbofuran? How to use carbofuran safely? Please introduce that the crops that carbofuran can act are rice, cotton, tobacco, sugar cane, soybean, peanut, corn, vegetable and so on. The following details introduce the methods of using carbofuran in various crops for reference. The use of carbofuran in rice can control rice borer, rice planthopper, rice thrips, rice leafhopper, rice gall midge, rice leafminer, rice water weevil, rice chironomid, etc.: application in the root zone: 2.5-3.0 kg of 3% carbofuran granules per mu before sowing or transplanting seedlings, and the residual period can reach 40-50 days. It can also be applied before sowing in late rice seedling field, especially for the control of rice gall midge. Water surface application: 1.5-2.0 kg of 3% carbofuran granules per mu, 15-20 kg of fine soil mixed well, evenly sprinkled on the water surface to keep shallow water, and can also control leeches. In order to increase the uniformity of distribution, 3% of the above dosage of furan granules can be evenly mixed with 10 times the amount of semi-dry soil to form poisonous soil, which can be evenly scattered on the surface of the water. When the water retention is good, the duration can be up to 30 days. Sowing ditch application: in the upland rice planting area, 3% furan granules and rice seeds were simultaneously applied into the sowing ditch, with a dosage of 2.0-2.5 kg per mu. Dry raised rice seedlings: 7-10 days before transplanting, 3% furan granules are applied to the seedling field, 7-10 kg per mu, that is, 10-15 g per square meter, to control rice leafminers occurring in Honda. The use of carbofuran in cotton can control cotton aphids, cotton thrips, ground tigers and nematodes, etc.: when sowing cotton, 1.5-2.0 kg of 3% carbofuran granules per mu are applied synchronously with the seeds. It is accurate and safe to apply medicine with a quantitative dispensing device in a motorized seeder. Root side topdressing: generally use furrow application or hole application method for topdressing, furrow application with 3% carbofuran granule 2-3 kg per mu, 10-15 cm from the cotton plant along the ridge, the depth is 5-10 cm, and the soil is covered immediately after application. It is appropriate to apply 0.5-1.0 grams of 3% granule per hole, and the effect is better if it can be watered after topdressing, and the effect can only be brought into play after 4-5 days of application. Seed treatment: cotton seeds should be delinked with sulfuric acid or foam sulfuric acid, and mixed with 35% carbofuran seed treatment agent 28ml and water per kilogram of cotton seed. The use of carbofuran in tobacco cultivation can control tobacco armyworm, tobacco aphid, tobacco root-knot nematode, tobacco leaf moth, small land tiger, mole cricket and other underground pests. Application at seedling stage: 15-30 grams of 3% carbofuran granules per square meter, evenly sprinkled on the seedling bed, and then turned into the soil 8-10 cm. One week before transplanting tobacco seedlings, the pesticide should be applied again on the soil surface, and then watered to wash the effective components of carbofuran into the root zone of tobacco seedlings, which can protect tobacco seedlings from pests in the early stage after transplanting. Honda application: when transplanting tobacco seedlings, 1-1.5 grams of 3% furan granules were applied in the transplanting hole. Sugarcane planting uses carbofuran method to control sugarcane pests: carbofuran is effective against sugarcane borer, golden needle worm, sugarcane aphid, sugarcane thrips and sugarcane nematode. Soil application method can be adopted to apply granules in the sowing ditch. 3% carbofuran granules 2.2-4.4 kg per mu, covering the soil after application. Planting soybean and peanut using carbofuran method soybean aphid, soybean root miner and soybean cyst nematode: control in sowing ditch with 3% carbofuran granule 2.2-4.4 kg per mu, covering soil after application. Peanut aphid, Spodoptera litura and root-knot nematode: the banded application method was adopted during the sowing period, with a bandwidth of 30-40 cm, 4-5 kg of 3% carbofuran granules per mu, and turned into 10-15 cm after application. In the adult stage of peanuts, side trenches can be applied, 33 grams of 3% furan granules are applied every 10 meters long ditches, and then covered with soil. Corn planting uses carbofuran method to control corn pests: 3% carbofuran granules are put into the corn leaf core (trumpet mouth) one by one according to the dose of 3-4 grains per plant in the corn trumpet mouth period, which can achieve good pest control effect. In addition, 35% carbofuran seed treatment agent 28 ml per kilogram of corn seeds mixed with 30 ml water can effectively control underground pests. The carbofuran method used in growing vegetables can control beet and vegetable pests: 35% carbofuran seed treatment agent is used for seed dressing of sugar beet, rape and other crops, and to control many kinds of pests such as beetles, weevil, thrips, aphids and so on. Carbofuran has strong adhesion. It has the advantages of uniform, not easy to fall off, good film forming, fast drying, luster, slow release and so on. Sugar beet seeds per kilogram with 35% carbofuran seed treatment agent 23-28 ml, add 40-50 ml water to mix well, then mix the seeds. If you can also prevent beet blight, you can add 50% Fumishuang wettable powder 8 grams, 70% soil bacteria wettable powder 5 grams and 5 milliliters of yield-increasing bacteria concentrate to mix seeds, it is best to use a medicine mixer. Rape seeds are mixed with 35% carbofuran seed treatment agent 23-28 ml per kilogram, water 30-40 ml plus 50% thiram wettable powder 8 g, 70% soil bacteria wettable powder 5 g and yield-increasing bacteria concentrate 5 ml, which can cure both diseases and insect pests and cultivate strong seedlings.
