#RiceSeedDisinfection #RiceCultivation #SpiralBlight Title: Rice_RiceSeedDisinfection ◎ Rice Seed Disinfection (Early April) ⇒ Rice Seed Sowing (Mid-April) ⇒ Rice Planting (Mid-May) ※ Standard: Cultivation of mid-late maturing varieties in the central plains ■ Rice Seed Disinfection: Hot Water Steeping / Soaking / Wet Mushroom Treatment ● The purpose of rice seed disinfection is to prevent spiral blight, rice blast, and sesame seed spot. One, two, or three disinfection methods are used. ※ Soaking alone is generally used, but combining spiral and wet mushroom disinfection increases the disinfection effect. For eco-friendly cultivation methods where pesticides cannot be used, hot water disinfection is used. ● Hot water soaking method: Soak rice seeds in 60℃ water for 10 minutes (58℃→15 minutes) ※ The amount of water is 10 times the amount of seeds (20kg of rice seeds in 200ℓ of water). ● Immersion disinfection: Soak rice seeds in a 30℃ disinfectant solution for 48 hours. ※ Government-provided seeds (red seeds) have been treated with a disinfectant, so soaking them in 30℃ water for 48 hours is sufficient for disinfection. ○ If the rice seed bags are soaked directly, the disinfectant will not penetrate deep inside, so please transfer them to a mesh bag with holes before disinfection. ○ Immersion disinfectant: Spotak (oil), Byessiwang (oil), Ariswiffer (liquid), Keyman (liquid), Goodtime (water), Gyunmagigold (oil), etc. ● Moisture treatment: Mix the soaked and sprouted rice seeds with a disinfectant or spray it before sowing. ○ Moisture disinfectant: Keyman (liquid), Ariswiffer (liquid), Sapphire (liquid), Javara (water), Bangbangbyeok (liquid), Cnjoa (liquid), Shina (liquid), Giraseong (water) ■ Insecticide: Add insecticide to the disinfectant to control ear nematodes and rice leaf nematodes. ○ Insecticide: Smithion (oil), Samep (oil), Revaigit (oil), Reldan (oil), etc.
