Correct Methods and Operating Steps for Disinfecting Rice Seeds
Rice seedling raising is about to begin, and seed disinfection is the key to raising seedlings. Here are 10 seed disinfection methods. 1. Soak rice seeds in a 500-fold dilution of 50% carbendazim, 50% thiophanate-methyl, or 50% thiram for 48 hours (200 g of the solution mixed evenly with 100 kg of water can soak 60-70 kg of rice seeds), then remove them, sprout them, and sow, ...
Rice seedling raising is about to begin, and seed disinfection is the key to raising seedlings. Here are 10 seed disinfection methods.
1. Soak rice seeds in a 500-fold dilution of 50% carbendazim, 50% thiophanate-methyl, or 50% thiram for 48 hours (200 g of the solution mixed evenly with 100 kg of water can soak 60-70 kg of rice seeds), then remove them, sprout them, and sow. This is fairly effective at preventing rice bakanae disease and can also control rice blast, rice brown spot, and rice seedling blight, etc.
2. Soak seeds in a 200-fold dilution of 40% trichloroisocyanuric acid. First soak the seeds in clean water for 12 hours, then place them in the solution and soak for 12 hours, then rinse them clean with water, remove them, sprout them, and sow. This can prevent rice bacterial leaf streak and rice bacterial leaf blight.
3. Soak seeds in a 0.2% copper sulfate solution for 48 hours, then remove them, sprout them, and sow. This can prevent rice bakanae disease, rice false smut, etc.
4. Soak seeds in a 500-fold dilution of 40% formalin. First soak the seeds in clean water for 1-2 days (until they have absorbed enough water but have not yet germinated), take them out and let them dry slightly, place them in the solution and soak for 48 hours, then remove them, rinse them clean with water, sprout them, and sow. Disinfection by this method can prevent rice blast, rice bakanae disease, rice brown spot, rice false smut, etc.
5. Soak seeds in a 0.15% "Xianjunqing" solution for 48 hours, rinse clean with water, then sprout and sow. This can prevent rice white-tip nematode disease, rice bakanae disease, etc.
6. Soak seeds in a 2000-fold dilution of 10% "Yekujing" for 24-48 hours, remove them, sprout them, and sow. This can prevent rice bacterial leaf blight, rice bacterial leaf streak, etc.
7. Soak seeds in a 0.1%-0.2% potassium permanganate solution for 24 hours. This can prevent many fungal and bacterial seed-borne diseases.
8. Soak seeds in a 500-fold dilution of 10% "Jinzhongling" for 48-60 hours. This can prevent bakanae disease and also control rice white-tip nematode disease, rice blast, etc.
9. Soak seeds in a 2000-fold dilution of 25% "Shibaike" for 72 hours. This can prevent rice bakanae disease, rice brown spot, etc.
10. Take an appropriate amount of 70% hymexazol ("Tujunxiao") and dress the rice seeds before sowing at 0.4%-0.7% of the dry rice seed weight. Either dry dressing or wet dressing is fine. This can prevent rice seedling blight, etc.
