Huzhou Yong, Jingzhou City, Hubei Province, said on November 23 that spraying 40 pounds of 12% clethodim EC per acre prevented spraying of Poa field in the rape fields. Only the tips of the weeds turned yellow after spraying, and they began to recover after a few days. When weeding, weeds are in the 5-6 leaf stage. He asked why the clethodim could not get rid of the bluegrass, and there are no other herbicides that can control it. The clethodim is a selective, post-emergence, post-emergence herbicide that is suitable for use in soybeans, rapeseeds and other broad-leafed crop fields. It can be used to look at amacia, bluegrass, Japanese maimai, valerian, wild oats, green foxtail, and horses. Tang and other grassy weeds all have good control effects. The drug can be rapidly absorbed by plant leaves (usually absorbed by weeds 1 hour after application), transmitted to roots and growing points, and inhibits the biosynthesis of branched fatty acids in plants. After weeding, the weeds grew slowly and lost their competitiveness. Young tissue was yellowed early, and the rest of the leaves wilted until death. The rapeseed field uses clethodim, which is generally used in the 3 to 5 leaf stage of the grass weeds, with 12% clethodim EC 30 to 40 ml or 24% clethodim EC to 20 to 25 ml per mu. According to Chen Jian et al., Shanghai Nanhui District Agricultural Technology Promotion Center, in the 4 to 6 leaf stage of rapeseed, 3 leaf to 4 leaf 1 heart stage of grassy weed, use 240 g/liter of clethodim EC to achieve 15 ml/mu. , 20 ml, 25 ml, 40 ml, 12% clitorone EC 40 ml, add 50 kg of water spray, prevent precocious scab, look Mai Aunt, hard grass, grass and other grass weeds. The test results showed that the use of 240 g/l clethodim EC 15 to 40 ml per acre had a significant control effect on the weeds in rapeseed fields and had a long duration. Use of 240 g/l clethodim EC in 15 ml, 20 ml, 25 ml, and 40 ml per acre for control of grass weeds: 150.3 days after application, strain control efficacy was 30.31%, 43 The control efficacy of .72%, 62.69%, 62.11%, 45 days after application was 83.67%, 92.95%, 93.24%, 98.15%; 90 days after application The fresh weight control of Poa pratensis was 0, 29.95%, 15.69% and 81.73%, respectively. Control effectiveness increases with the amount of drug used. With the same amount of active ingredient, the efficacy of 240 g/l clethodim EC is better than that of 12% celeary ketone EC. The low and medium doses of 240 grams/liter clethodim EC had no obvious effect on bluegrass, but the effect of high dose on bluegrass was obvious. Therefore, in the rapeseed field, which is dominated by the early maturing pods, the spraying efficiency of 240 kg/liter clethodim EC 40 ml and 50 kg water per acre in the 3 to 4 leaf stage of weeds is good. In an interview with reporters, technical personnel of Jiangsu Longdeng Chemical Co., Ltd. said that in recent years, rapeseed fields in some areas of our province have been used for a long period of time and clethodim has been used, resulting in that the application of pesticide at the recommended dosage cannot effectively prevent the premature pods. In particular, in the earlier Sunan region where the use of clethodim was popularized, some plots need to be applied twice in order to ensure efficacy. Therefore, in the continuous application of clethodim for 5 to 6 years, the control effect can be reduced by appropriately increasing the amount of the drug. Generally, 12% of clethodim emulsifiable concentrate is increased to 60-80 ml, and 24% clenopyranyl chloride is increased to 40-50 ml to ensure efficacy. Precocious pods 2-5 leaf stage is the best period for removal. The control effect of grass age above the 5 leaf stage is decreased. Appropriate increase in the amount of pesticides has a certain control effect. The use of clethodim in Hubei Province is only 2 to 3 years, and the use of 12% clethodim EC in a dose of 40 ml per mu can ensure the control of Poa pratensis. The above-mentioned plots were used during the early stage of the 5-6 leaf stage of the early mature pods. When the pesticides were used, the grass age was too large and the drug resistance was enhanced, which may be the main reason for the decrease of the control effect.
Microblading, also known by a variety of names such as embroidery, microstroking, feather touch and hair like strokes, is a form of Permanent Makeup that provides a means to partially or fully camouflage missing eyebrow hair with the appearance of simulated hair using fine deposits of cosmetic tattoo pigments. The technique of implanting pigment after the creation of fine incisions in the skin may date back thousands of years [1] however the trend towards using the technique for eyebrows emerged in Asia and was known as feathering or embroidery prior to becoming known as microblading. Dr. Linda Dixon coined the term microstroking, which is used synonymously with microblading.
