In the process of sugar cane cultivation, if not managed properly, it is easy to cause various pests and diseases, resulting in reduced yields and economic benefits of sugar cane. It is therefore important to understand the characteristics and conditions of all pests and diseases that occur in sugarcane throughout the reproductive period. What are the common pests and diseases of sugarcane and how can they be controlled? Let's find out more!
1. Pineapple disease
It is mainly caused by seed infection. When the disease occurs, the cane will have a pineapple-like fragrance, the cuts will be red and the seedlings will turn black at a later stage. The disease is harmful to the germination of sugar cane seeds, and the growth of young seedlings is weak, resulting in the death of the cane.
Prevention and treatment: Mulch the sugar cane at planting time to prevent invasion by pests and diseases. Seeds can also be dipped in 3% lime water. After cutting, the roots need to be disinfected with a combination of carbendazim and cane stems.
2. Smut
This disease is caused by high temperatures and humidity and affects the normal development of the cane.
Prevention and treatment methods: When planting sugarcane, dip the seeds with 0.5% methoxyethyl mercuric chloride, apply phosphorus and potassium fertilizers on sugarcane and implement crop rotation, which can effectively reduce sugarcane diseases.
3. Maculopathy
It mainly causes the leaves to wither and affects the absorption of nutrients by the sugarcane and appears as irregular yellow spots.
Prevention and treatment methods: timely exclusion of waterlogged sugarcane fields, good fertilizer management, selection of high-quality disease-resistant varieties, and post-disease spraying of Poladox liquid for prevention and treatment.
Once the disease develops, it will cause serious damage to the stalks and reduce the survival rate of sugarcane.
Prevention and treatment methods: Eliminate the source of insects, timely remove cane stems and dead leaves to eliminate the source of overwintering insects, select seedlings with strong disease resistance, apply sufficient base fertilizer, and implement crop rotation with rice and sweet potatoes.
The above is a comprehensive introduction to the control of common pests and diseases of sugarcane. Farmers who want to plant high-yielding sugar cane must master the scientific pest control methods, I hope the above content can help you.
