What are the common control methods for sugarcane pests and diseases?

Sugarcane tastes sweet and is a fruit we enjoy, 1and it is also one of the main raw materials for making white sugar, with a very large planting area in our country. However, during the growing process it is often troubled by many pests and diseases, which reduce the yield and quality of sugarcane. Below, Qinnong Web brings you the common control methods for sugarcane pests and diseases. Let's take a look together.

1. Pineapple disease

Seeing this disease may make you feel it is strange - pineapple is a fruit, so how can it be related to a disease? Actually it is not so. Pineapple disease is named pineapple disease because after sugarcane is infected, the sugarcane gives off a pineapple-like fragrance. It is caused by pathogens remaining in the soil. The pathogens invade through the cut of the seed cane. When the disease begins, the cut of the seed cane turns red; as the disease worsens, the internal tissues of the seed cane all become infected and turn black. In mild cases the seed cane grows thin and weak and develops poorly, and in severe cases it causes the death of the seed cane.

Control methods: This disease occurs under low temperature and high humidity or long periods of cloudy and rainy weather. The control method is mainly prevention. Measures are taken to make sugarcane sprout and emerge early, chemicals are used to disinfect and sterilize the cut of the seed cane, and after the disease occurs, chemicals are used promptly for treatment.

2. Red rot

Red rot, like pineapple disease, is also caused by pathogens. It mainly harms the stem and leaves. It is difficult to detect in the early stage of the disease. It begins by forming white round patches in the internal tissues of the stem, and as the disease worsens, the leaves begin to turn white and die.

Control methods: Red rot mainly occurs under high temperature and high humidity, relatively high planting density, and excessive application of nitrogen fertilizer. Choose varieties with strong disease resistance, disinfect and sterilize the seeds before planting, promptly pull out and destroy diseased plants when found, and then spray chemicals for control.

3. Smut

Smut is a fungal disease. When it occurs, a section of black spike-like matter grows from the top of the stem. This black spike is short and straight, with no branches. After sugarcane is infected with this disease, it grows slender, affecting yield.

Solutions: This disease occurs in dry and barren conditions or under high temperature and high humidity as well as in the rainy season, and it is mainly spread through the air. Choose varieties with strong disease resistance, soak the seeds in 0.5% methoxyethylmercury chloride for disinfection and then plant. After planting, strengthen fertilizer and water management, apply more phosphorus and potassium fertilizer to promote sugarcane growth and strengthen disease resistance. After the disease is found, promptly pull out and burn the plants, immediately spray chemicals for control, and avoid continuous cropping.

4. Borers

Borers, also called sugarcane stem borers, have extremely strong reproductive capacity and no obvious dormant period. They harm sugarcane in all four seasons, often boring into the interior of sugarcane, causing the sugarcane to become hollow, and in the seedling stage they easily form dead hearts. Even after growth, the plants are extremely weak and very easy to break. Their damage also easily causes the invasion of other diseases, and they are extremely harmful to sugarcane.

Solutions: Borers can safely overwinter in sugarcane fields, so after harvest, promptly remove and burn all the residual branches, leaves, and stems in the sugarcane field, then flood the sugarcane field and soak it for 2-3 days to thoroughly eliminate the source of the insects. Disinfect the seed cane before planting. When damage is found, promptly pull out the affected sugarcane or carry out chemical control.

The above are the common control methods for sugarcane pests and diseases brought by Qinnong Web. The introduction to sugarcane pests and diseases ends here. The control of sugarcane pests and diseases is mainly based on prevention, and management should be strengthened at ordinary times so as to avoid losses when pests and diseases occur.
