Rice panicle neck disease is one of the most destructive rice diseases, significantly reducing both yield and grain quality, and causing serious economic losses to farmers. Timely application of **pesticides** is essential to control the spread of this disease, ensuring healthy rice production and high-quality harvests.
Symptoms of the disease typically appear during the heading and filling stages of rice growth. It is primarily caused by airborne pathogens that thrive under favorable climatic conditions. Infected rice plants often show signs of necrosis in the neck area of the panicle, which blocks the flow of nutrients to the grains. This results in white or empty ears, leading to significant yield losses. The damage can be severe if not addressed promptly.
The key period for prevention and control is during the heading stage of the rice plant. During this time, it's crucial to apply appropriate fungicides to prevent infection and minimize damage.
For treatment, several effective options are available. Farmers can use 25% of the active ingredient (mimiline), 75% tricyclazole, 40% Fujimil, 40% of a specific fungicide for panicle diseases, and 40% of a rice-specific formulation. These products should be applied according to the manufacturer's instructions to ensure maximum effectiveness.
The best time to spray pesticides is on a sunny day after the morning dew has dried. It’s important to avoid spraying if rain is expected within the next 10 hours. If it rains, reapplication may be necessary. Ensure that there is enough water in the spray solution to cover the entire crop. When applying, aim the sprayer nozzle upward and spray from the bottom up to improve coverage and penetration.
It is recommended to conduct at least two rounds of pesticide application for optimal control. The **Chinese Pesticide Network** advises farmers to rotate different types of pesticides regularly to prevent the development of resistant strains of the pathogen.
In addition to chemical control, proper field management, such as maintaining good drainage and avoiding excessive nitrogen fertilization, can also help reduce the risk of disease. Monitoring the fields regularly and taking early action when symptoms first appear can make a big difference in preventing widespread damage.
By following these guidelines and staying proactive in disease management, farmers can protect their rice crops and achieve better yields and higher quality harvests. Always refer to local agricultural extension services for region-specific recommendations and best practices.
