50% Butachlor: Apply 100-170 ml per acre before sowing. Ensure the seedbed is in a wet state, and after sowing, cover the seeds with a thin layer of soil (0.5-1 cm) followed by a plastic film. Three days prior to sowing, lightly spray the bed with a shallow water layer, but avoid standing water. Before the 2-3 leaf stage, apply the herbicide when the rice has 2-3 leaves. After application, drain the field for 2 days, then reapply water for 5-7 days. After transplanting, maintain a 3 cm water layer for 3-7 days. Important notes: Keep the bed in a wet-dry cycle, avoid flooding before the Qimiao irrigation. After irrigation, keep the water shallow. Ensure the bed surface is level and the herbicide is evenly distributed.
Killing Crickets: At the 2-leaf stage, apply 25 g per mu of the insecticide. If the rice has more than 2 leaves, increase the dosage by 5 g per additional leaf. For example, 3 kg of rice requires 10 kg of water mixed with 5 g of the product. Spray the solution on dry ground, then irrigate with 2-3 cm of water 2-3 days after application. Keep the water for 5-6 days. Precautions: Avoid using this during the early stages of rice germination. Do not mix with paclobutrazol or uniconazole. Allow a gap between applications.
96% Hedaizhuang: Use 100 ml per acre for barnyard grass at the 2-leaf stage. Mix the herbicide with a shallow water layer and apply it to the soil. Retain the water for 5-7 days. Note: Ensure the water level does not submerge the young rice leaves. After transplanting, apply 100-200 ml depending on the growth stage. During the 2-4 leaf phase of barnyard grass, maintain a water layer for 7 days. This helps control weeds effectively while protecting the rice plants.
These practices are essential for optimal weed and pest control in rice fields. Always follow the recommended dosages and application methods to ensure the health of your crop and the environment. Regular monitoring of the field conditions will help you adjust the timing and amount of water and chemicals as needed. Proper preparation and careful execution of these steps can significantly improve yield and reduce losses due to weeds and pests.
