Sugarcane borers are very harmful. What are the control methods of sugarcane borer?

Sugarcane is one of the main raw materials in China's sugar industry. The key is to plant it in the south of China. Now the market demand in the market is still increasing. However, in the process of sugarcane planting, if the management method is unreasonable, various diseases and pests will easily occur, which will limit the yield of sugarcane and affect the economic benefits. What are the common diseases and pests of sugarcane, and what are the control methods? Let's master it together

1, pineapple disease

The key to the disease is that the seeds are sick. After the onset, sugarcane will present pineapple-like aroma, the wound will turn red, and the seedlings will turn black in the middle and late stages. The disease has a great influence on the germination of sugarcane seeds, which weakens the growth and development of seedlings and seriously leads to the death of sugarcane.

Control method: Cover sugarcane with agricultural plastic film to avoid the erosion of pests and diseases. At the same time, the seeds can be soaked with 3% hydrated lime powder, and the cut roots can be disinfected with triadimefon and sugarcane wine.

2. Head smut

After the disease, a gray-black whiplike substance grows on the top of sugarcane stem. The disease is mainly caused by the continuous high temperature and low temperature natural environment, which will affect the normal growth and development of sugarcane.

Prevention and control methods: When planting sugarcane, soaking seeds with 0.5% Methoxychloride, upgrading phosphorus and potassium fertilizer for sugarcane and implementing rotation planting can effectively reduce the occurrence of diseases.

3. Macular disease

The key to this disease is the withering of leaves, which affects the digestion and absorption of nutrients in sugarcane and produces irregular yellowish spots. With the growth and development of sugarcane, the yellow spots gradually increase, and will appear red in the middle and late stages.

Prevention and control methods: directly remove the accumulated water in sugarcane fields, do a good job in fertilizer management, select high-quality disease-resistant varieties, and spray Boleduo solution for prevention and control after the disease occurs.

4. Borer

Stem borers have long harmed sugarcane. Once the disease occurs, there will be dead seedlings, which will obviously destroy the sugarcane stalks and reduce the survival rate of sugarcane.

Prevention and control methods: solve the insect source, immediately eliminate the residual stems and branches in sugarcane fields, eliminate the overwintering insect source, select seedlings with strong disease resistance, apply sufficient fertilizer, and rotate with rice and sweet potatoes. After the onset, spraying 90% trichlorfon crystal 500 times solution sprayer or 25% chlorfenapyr 500 times solution sprayer for control, the actual effect is very good.

The above is the prevention and control of common diseases and pests in sugarcane. Farmers must master scientific pest control methods if they want to grow high-yield sugarcane. I hope the above contents can help everyone.
