Buy wheat field herbicides , mainly used to control the bluegrass in the field. Which kind of medicine is used under the current low temperature conditions?
There are few herbicides suitable for the treatment of grass weeds in the treatment of wheat stems and leaves. Among them, only isoproturon has better control effect on bluegrass. Other pharmaceuticals, including the Swiss Syngenta Crop Protection Co., Ltd.'s newly launched Ai Xiu 50 g / liter of oxazolin ester emulsifiable concentrate for the control of weeds in wheat fields, are poorly effective against bluegrass.
Isoproturon has been used in production for many years, and many places of bluegrass have also developed strong resistance to this drug. Applying medicinal herbs for a small amount of time, and increasing the dosage of the drugs, is conducive to improving the control effect. In addition, the medicine will reduce the anti-freezing ability of the wheat seedlings, and it is easy to cause phytotoxicity to the wheat seedlings after the application of the severe frost weather. The above-mentioned field suggests that after the temperature rises, try to use the "cold tail warm head" early when the grass age is small, and increase the dosage when the grass age is large. Pay attention to the weather forecast to ensure that the lowest temperature below 0 °C does not occur within 1 week after application. When the soil in the field is relatively moist, the application is beneficial to improve the control effect. At low temperature, it should also pay attention to the selection of high-quality isoprolongol products, such as 50% isoproturon WP of Suzhou Baodai Pesticide Co., Ltd. (telephone), which is beneficial to improve the herbicidal effect and reduce the risk of phytotoxicity. When the application conditions are suitable (for example, the wheat seedling is more robust and the temperature is higher), if the field grass is relatively large, the 50% isoproturon WP can be increased to about 250 grams.
