What is the control method of sugarcane pest and disease and sugarcane shoot rot?

1. Choose disease-resistant varieties such as cinnamon sugar 57 624 and Yuetang 63 23.

2. Nitrogen, phosphorus and potassium should be applied reasonably and appropriately to avoid partial application of nitrogen fertilizer. Remove the stagnant water in the sugarcane field in time and reduce the humidity in the field. After the sugarcane is harvested, the diseased leaves and remnants of diseased plants left in the sugarcan field should be removed in time and burned in a centralized manner to reduce the source of infection.

3. For disinfection of sugarcane seedlings, you can use 50% carbendazim, chlorothalonil or methyl tobuzine 1000 times, or 50% benzolite 500 times, soak the seeds for 5 10 seconds.

4. Spray 1 000 times of 50% carbendazim wettable powder, or 1 000 times of 50% benmonyl wettable powder, or 1 1 100 times Bordeaux liquid spray, or 500 times of 30% basic copper sulfate suspension in the early stage of sugarcane shoot rot. Spray 1 time every 7 10 days, 3 4 times in a row. When spraying, it should be carefully sprayed on the head of the sugarcane tip to improve the control effect.

The disease is capable of affecting sugarcane seedlings, and is usually caused by the disease through the soil, and unstable environmental factors.

To prevent this disease, you can choose healthy and thriving plants to cultivate before planting. During the growth of seedlings, the film can be covered to reduce the contamination of diseases, and the sterilization treatment can be carried out with pesticides to prevent and control diseases, which can effectively solve such problems.

This disease is very harmful to sugarcane, usually can cause a large area of sugarcane death, especially in arid areas, causing huge losses, this phenomenon mostly occurs in China's sugarcane planting areas, is a very common disease.

For this disease, the first thing to do is to cultivate seedlings, soak the seeds through antibacterial agents before planting, and then choose a place where the land is not polluted for planting, apply more fertilizer and water frequently, remove the diseased plants in time, and effectively prevent and control this disease.

Brown streak disease mainly harms the leaves of sugarcane, and after being infected with this pathogen, it causes the leaves of sugarcane to turn yellow and cannot develop normally, which reduces the yield of sugarcane and affects the harvest.

Plants with antimicrobial genes can be selected for cultivation to increase the content of soil organic matter and maintain the ventilation of sugarcane fields. It was found that the concurrent branches and leaves were removed and sprayed with pesticides to resist, which could have a good effect.

Bromeliad disease is one of the common diseases of sugarcane, the temperature needs to be controlled at a constant temperature condition is small, and the use of carbendazim agent for disinfection, in the high temperature and humid environment sugarcane is prone to red rot and smut, the seeds need to be disinfected before sowing, and the later breeding needs to maintain a well-ventilated environment.

1. Bromeliads

Bromeliad disease is one of the disease prevention and control of sugarcane, sugarcane due to infection with pathogens, the diseased place will be red, if it is not carried out in time, the plant will turn red to black, and the sugarcane will emit a pineapple aroma, at this time you can spray carbendazim for disinfection and sterilization treatment, and at the same time increase the temperature.

2. Red rot

Red rot is also a common disease of sugarcane, mainly harming the stems and leaves of sugarcane, the disease will grow a lot of white round spots in the early stage of the disease, so the seeds need to be disinfected before sowing, avoid being in a high temperature and moisturizing environment, during which nitrogen fertilizer can not be applied excessively, and chlorothalonil solution can be sprayed every other month for disinfection.

3. Smut

Sugarcane suffering from smut is mainly due to the fungus attack, this disease mostly occurs in high temperature and high humidity environment, before planting the disease-resistant varieties, after which the seeds can be soaked with methoxyethyl chloride for disinfection, if sugarcane is found to have this disease, it needs to be removed in time and sprayed with special agents.

4. Worms

The reproduction ability of the borer is particularly strong, and can be propagated all year round, so that the sugarcane plant is prone to breakage, and the residual leaves and diseased branches can be disposed of in time after the sugarcane harvest, and the water is released to soak the field for 2 3 days, and the carbendazim solution is used for disinfection treatment, which can reduce the occurrence of this insect pest.

When sugarcane suffers from the harm of cotton aphid, it needs to be placed in the sun, and sprayed with dichlorvos, dimethoate and other pesticides for control, borers need to improve the ventilation environment, and need to be sprayed with pesticides such as emulsifiable concentrate and insecticidal double water agent for the prevention and control of thrips, thrips need to be sprayed with thiamethoxine and other pesticides for control, ground tigers need to replace new potting soil, and dichlorvos and other pesticides need to be poured into the soil for control.

1. Aphids

The growth rate of sugarcane is relatively fast, but it is easy to suffer from the harm of cotton aphid, if you ignore sugarcane for a long time, it will gradually erode the plant, it is best to cause it to wilt and die, then you need to put the plant in the sun, spray it with dichlorvos, dimethoate and other agents to prevent and control it.

2. Borers

If the sugarcane growth environment is not comfortable, then it is also easy to suffer from the damage of borer, the borer is known as the borer, after gnawing on the stem of sugarcane, reducing the yield of its plant, it is necessary to improve the ventilation environment, but also to spray the plant with pine molasition, insecticidal double water agent and other pesticides for control.

3. Thrips

In fact, thrips in sugarcane pest control, is also one of the most common insect pests, it will absorb the nutrients of the plant, so that sugarcane in the soil growth poorly, need to understand to give it fertilizer maintenance, but also to move to a ventilated, sunny environment, to spray it with thiamethoxam and other pesticides for control.

4. Ground tiger

Sugarcane has a strong ability to adapt to the environment, especially the drought tolerance of the plant, but if the growing soil is not suitable, it will suffer from the harm of the ground tiger, affecting the growth of plant roots in the soil, and it needs to be replaced with new soil immediately, and it is also necessary to water the soil with dichlorvos and other pesticides to prevent and control.
