Ryegrass control in wheat fields
Oxaldoline has better efficacy against ryegrass, alfalfa, wild oats, green foxtail, hardgrass, acorns, Japanese acacia, and clubhead weeds. It is recommended for grass weeds 2 At the 5th leaf stage, sensitive weeds stopped growing 2 days after application, and the weeds began to yellow in 1 to 2 weeks, and weeds completely died in 3 to 4 weeks. Sulfoxanthrine to Bromegrass, Alopecurus, Japanese Acacia, Wild Oats, Rye Grass, Hard Grass, etc., and Gramineae, Wild Barnyardgrass, Amaranth, Sophora japonica Grass has better control effect. The drug is highly active and should be administered strictly in accordance with the recommended dose, application period and method. Within 2 days after application, there could not be large cold weather. When the minimum temperature was lower than 0°C, the medication should be stopped to avoid causing injury to wheat. Xifazosulfuron is able to control some broad-leaved weeds such as amaranth in wheat fields, acorns in Japan, bromegrass, ryegrass, wild oats, alfalfa grass and other broad-leaved weeds such as leeks, wild peas, and blue vegetables. In the early winter before winter or early winter, weeds before the 3 leaf stage early application, generally 15 to 20 days after sowing wheat application, in order to take full advantage of the characteristics of the drug killing, water consumption per mu is not less than 30 kg. The drug has good safety to wheat and can be applied before the jointing of wheat. The adaptability to low temperature frost is good, but it is better to apply the pesticide when the daily maximum temperature is higher than 8°C. The field cannot be accumulated for a long time after application. water. In the weeds before the 3-leaf stage, generally use 70% of chlorsulfuron-methyl per acre 3 to 4 grams, when the age of the grass can increase the amount of medication, 70% perchlorate with 5 to 6 grams of chlorsulfuron-methyl. Methylsulfuron can control some broad-leaved weeds such as annual grasses and weeds, such as barley, bluegrass, hard-grass, acorn, Japanese acacia, alfalfa grass, ryegrass, and clubhead. The drug has high technical requirements for pesticide application, and production must be strictly followed according to the instructions. It cannot be applied in the adverse environment where waterlogging ability, drought, disease, alkaline soil, etc. may cause the decline of wheat seedling viability and growth inhibition. Grasp at sunny noon approx. 5 °C above average daily temperature, do not appear in the short-term after the application of a large temperature-fallen weather, otherwise wheat will appear dwarfing, chlorosis and other phenomena.
