First, pests and diseases
The most prone pests in early spring wheat are: wheat spiders and wheat bran. The main pesticides for controlling wheat spiders include avermectin, omethoate, etc. The main agents for controlling wheat aphids are: once-in-a-net, imidacloprid, etc.
With the gradual warming of the weather, midge, sheath blight, and powdery mildew. Rust and other diseases also occur. At present, there are many pharmaceutical agents for controlling wheat diseases and insect pests, such as 2.5% of Lambda-cyhalothrin and 480 g/L of imported chlorpyrifos emulsified oil, which have better control effects on wheat aphids, red spiders, and wheat weedworms. Quick-dissolved boron, potassium polymer and other fertilizer products can effectively improve wheat disease resistance, increase production and improve quality. These products are not only expensive but also affordable, and are very suitable for the prevention and control of early spring wheat diseases and insect pests.
Second, grass damage
At present, there are many types of herbicides sold on the market, and the main components are the following four: tribenuron, thifensulfuron, an ice dragon, and chlorophenoxyacetic acid, of which tribenuron is most commonly used, and is often associated with ethyl carboxymethyl herbicide ether, Bensulfuron-methyl and its ingredients, such as chlorsulfuron, are used in combination to expand weed spectrum and improve weed control. However, it is better to use tribenuron-methyl instead of tribenuron-methyl in peanuts and other dicotyledonous crops. The specific dose should be used according to the specifications of the pharmaceuticals. Use should be strictly in accordance with the instructions. Never abuse blindly so as not to cause injury.
