The combination of the four methods of control of shallots
It is essential to follow the plant protection policy of "prevention first, integrated prevention and control" and actively promote the concept of "public plant protection and green plant protection." This approach prioritizes agricultural, biological, and physical control methods, along with the scientific and rational use of chemical controls. The use of highly toxic and persistent pesticides should be strictly prohibited.
Agricultural control involves using disease-resistant crop varieties, proper planting layouts, crop rotation, seed treatment, balanced fertilization, and improved field management. By maintaining healthy growing conditions, we can enhance the crops' natural resistance to pests and diseases. Keeping the farmland clean and reducing pest breeding grounds also plays a vital role in long-term pest management.
Biological control focuses on protecting and promoting the population of natural predators that help regulate pest numbers. Pesticide manufacturers recommend using products that are less harmful to beneficial insects, such as *Bacillus thuringiensis* and *agricultural streptomycin*. These options support a more sustainable and environmentally friendly approach to pest management.
Physical control methods include the use of "three lures" technology: installing solar-powered insecticidal lamps every 20–40 mu, placing 20–30 yellow or blue sticky boards per acre, and setting up two traps per acre with attractants to capture pests. These techniques effectively reduce pest populations without the need for chemicals.
Chemical control should be used as a last resort and applied strategically. For soil disinfection in fields with severe pest and disease problems, a mixture of 50% carbendazim or 70% dipyridamole WP (1–2 kg per acre) combined with 3% phoxim granules (1.5 kg per acre) mixed into fine soil is recommended. All fields should be evenly treated.
For weed control, herbicides like oxyfluorfen or diuron can be applied at the right time after sowing. When it comes to controlling major pests such as thrips, leaf miners, and cutworms, high-efficiency insecticides like cypermethrin, imidacloprid, and bio-pesticides like avermectin are effective choices.
For diseases like purple spot and leaf blight, early application of fungicides such as metalaxyl-manganese zinc and difenoconazole can prevent further spread. These treatments should be applied every 7–10 days, with 2–3 rounds of joint application. It's important to alternate between different chemicals to avoid resistance.
For downy mildew, early intervention with mancozeb, metalaxyl-manganese zinc, or dimethomorph can significantly reduce damage. In the case of gray mold, carbendazim, thiophanate-methyl, and pyrimethanil are commonly used for both prevention and treatment.
By combining these strategies, farmers can achieve effective and sustainable pest and disease management while minimizing environmental impact and ensuring food safety.
