To ensure a successful pre-sowing seed treatment and lay a solid foundation for the healthy growth of Miao Qi, Miao Quan, and Miao Zhuang, it is essential to implement effective disease and pest prevention measures. Proper seed treatment not only enhances germination rates but also significantly reduces the risk of crop damage caused by diseases and pests. Therefore, it's crucial to promote and adopt these practices widely.
For rice seeds, the first step is to select an appropriate seed treatment agent, followed by drying the seeds for 1–2 days. One effective method is soaking the seeds in Tricyclazole solution: mix 20% Tricyclazole powder at a ratio of 750 times (i.e., 50 grams of powder per 37.5 kilograms of water) and soak the seeds for 12 hours. Afterward, rinse the seeds thoroughly with water before sowing. This helps prevent rice blast disease effectively.
Another option is using Strong Chlorine solution: prepare a 10% strong chlorine crystal solution at a dilution of 500 times (10 grams of medicine per 5 kg of water), soak the seeds for 12 hours, then rinse and sow. This treatment helps prevent rice blast, bakanae disease, and stripe disease.
For further protection, Kwong Ku Ling solution can be used: mix 3% Kwong Ling water agent at a ratio of 500 times (10 grams of medicine per 5 kg of water), soak the seeds for 24 hours, then rinse and sow. This method is particularly effective against rice blast disease.
For corn seeds, similar steps are taken. First, choose a suitable seed treatment agent, then dry the seeds for 1–2 days. One common method is soaking in Carbendazim solution: use 50% Carbendazim powder at a 1000-fold dilution (5 grams of powder per 5 kg of water), soak for 48 hours, then plant directly. This helps prevent corn blackhead disease.
Another method is dusting the seeds with Rust Powder: mix 15% rust powder at a ratio of 5 grams per 1 kilogram of corn seeds. This helps protect against corn smut.
For controlling underground pests and rodents, Methamidophos can be applied as a seed dressing. Mix 50% Methamidophos EC at a rate of 50 grams per 0.5 kg of seed, treating 5 kg of seeds. After application, let the seeds sit for half an hour before planting. However, if the seeds are already coated, this method should not be used again.
By following these detailed seed treatment procedures, farmers can significantly improve crop health and yield, ensuring a strong start for their plants. It's important to always follow the recommended dosages and safety precautions when handling chemical treatments.
