A peasant in Huaiyang County, Zhoukou City, Henan Province, inquired. What kind of herbicide will be used after wheat? How to prevent and treat pests and diseases?
Zhou Xiaojing (Master of Plant Protection), an assistant agronomist of Sinochem Fertilizer Henan Branch: There are many types of herbicides currently available on the market for wheat weed control, but the main components can be roughly divided into 4 types: tribenuron, thiophene sulfone, Isoproturon and 2-methyl-4-chlorophenoxyacetic acid, of which tribenuron is most commonly used, and often used in combination with ethyl flufenazone, bensulfuron methyl, 2.4-D and its ingredients. In order to expand weeding spectrum and increase weeding effect, it is best not to use tribenuron-methyl in dicotyledonous crops such as peanuts, but to use phentosulfuron-methyl, and the specific dosage should be based on the characteristics of the medicine and strictly according to the instructions. , if necessary, consult relevant experts.
In terms of pest control, the diseases that are prone to occur in the early spring are wheat spiders and wheat aphids. The main pesticides used to control wheat spiders include dicofol, avermectin, omethoate, etc. The main agents for controlling wheat aphids are: once-in-a-life, imidacloprid, etc. . With the warm weather, there are many occurrences of midge, sheath blight, powdery mildew, and rust. There are many drugs used to control wheat diseases and insect pests in Sinochem's products, such as: 2.5% of Lambda-cyhalothrin and 480g/L of imported chlorpyrifos emulsifiable concentrate have good control effect against wheat aphids, red spider, and wheat midge; Sinochem The quick-dissolved boron, polymerized boron potassium and other micro-fertilizer products can effectively improve the disease resistance of crops, increase production, and improve quality. These products are not only of good quality but also affordable, and are very suitable for the majority of farmers.
The valve is a series of gas emergency shut off solenoid valves, specially designed as gas pipe breaker for emergency use. It can be connected with gas leaking detection sensor, fire alarm circuit or other intelligent sensor modules so that on site or remote shut down on gas supply (manually or automatically) is possible, hence ensuring the safety on gas usage. The valve features an auto-close when strong vibration is detected. After close, manual operation is required to turn on the valve. This feature meets safety regulations in the event of an accident.
