If you find that your seeds have worms, it's important to take immediate action. Following the principle of "safe, economic, and effective" pest control, you should implement measures as soon as possible to minimize damage and loss. In agricultural practices, common methods for controlling seed pests include physical, mechanical, and chemical approaches.
Physical control involves using natural or artificial means such as high or low temperatures, radiation, or other energy sources to disrupt the reproductive and physiological functions of the pests. This can lead to the death of larvae by either preventing their growth and reproduction or denaturing proteins in their bodies. For example, exposing seeds to sunlight or freezing can reduce moisture levels, making the environment less favorable for pests and directly killing them.
Mechanical control uses tools like windmills, sieves, or manual labor to separate pests from the seeds. These methods not only help in removing the pests but can also kill them through physical impact or movement.
Chemical control involves the use of toxic substances such as aluminum phosphide, chloropicrin, or dichlorvos. These agents interfere with the pests' normal bodily functions, making it impossible for them to survive or reproduce. While chemical treatments are efficient, fast, and cost-effective, they must be used carefully. Improper application can harm seed germination or pose risks to human health. Therefore, it's crucial to follow proper safety protocols when handling these chemicals. It’s advisable to involve experienced personnel to ensure safe and effective application, reducing the risk of accidents and ensuring optimal results.
