Symptoms of Fusarium Wilt

Wilt disease, also known as blight, is a disease caused by fungi or bacteria that can cause serious damage to plants. This disease often occurs suddenly, causing severe spots on the leaves of the plant, and causing the leaves, fruits, and rhizomes of the plant to wither and gradually die. For some economic crops, it causes relatively large economic losses. Let’s take a look at this

Symptoms of Fusarium Wilt

Prevention and control methods include destroying diseased parts, rotating crops; pruning and thinning plants to improve ventilation; using disease-free seeds or rootstocks and disease-resistant varieties; controlling fungal pests to prevent them from spreading the disease among plants; avoiding top watering or working among wet plants, and applying fungicides when necessary. For bacterial diseases (such as fire blight), applying non-volatile copper agents or streptomycin weekly during the wet season when the branches and leaves are expanding is effective. To prevent and control yellowing and wilt diseases, use 300-500 times of methyl K·10-15g of fungicide, add 40g of "Kuanxin" foliar nutrient solution from Xi'an Zhongsheng Chemical, and spray it all over the crops that are just beginning to become ill; at the same time, use 600-700 times of 80% carbendazim to irrigate the roots. Practical application has proven that it is simple and practical. Compared with other drugs, it has the dual benefits of low prevention and control cost and fast cure effect, and it has a one-time cure effect on yellowing and wilt diseases.

Countermeasures

Trichoderma has antagonistic effects on many important plant pathogenic fungi, has a wide range of prevention and control, and has broad application prospects. As a biological control fungus, Trichoderma has the following advantages: 1. It has strong saprophytic properties and a wide range of adaptability; 2. It has a wide parasitic range and can be used for multiple purposes, which reduces the cost of prevention and control and is easily accepted by customers; 3. It can produce various antibiotics and lytic enzymes while parasitizing, reducing the drug resistance of pathogens and enhancing the antibacterial strength; 4. The chitinase gene of Trichoderma can be expressed in bacteria, fungi and plants, which is of great significance for preventing plant fungal diseases and promoting agricultural production.

1. Eradicate diseased plants in time and sterilize the original holes. 2. When watering, water the healthy plots and the diseased plots separately. 3. When irrigating, make sure the entire crop is fully rooted. 4. Do not water the plants within 3 days after using the medicine. If it rains or watering is necessary, use the medicine again in time after the rain or watering.
