A Detailed Guide to Using Daoqingqing Herbicide

Daoqingqing herbicide is a chemical specifically used to control weeds in rice fields. It kills weeds faster and more thoroughly, making it a good helper for farmers in rice field weed control. So what is the usage method of Daoqingqing herbicide?

1. What is the usage method of Daoqingqing herbicide?

Before applying the herbicide, drain the water from the field, then use 120-150ml of Daoqingqing per mu diluted in 30 kg of water and spray it evenly on the stems and leaves. About 1-2 days after application, refill the field with water in time. If the field is dry, irrigate with a moderate amount of water before applying the herbicide.

2. What precautions should be taken when using Daoqingqing herbicide?

1. As the age and density of weeds increase, the dosage should be appropriately increased; applying the herbicide with a high-concentration fine spray method can improve the control effect.

2. Before application, drain the field water so that the weed stems and leaves are fully exposed above the water surface; refill the field with water 1-2 days after application, with the water depth not exceeding the rice seedling hearts.

3. Maintain the water layer for 5-7 days, then return to normal management.

4. If the field is dry at the time of application, to ensure the herbicide's effectiveness, irrigate with a moderate amount of water before applying.

5. Spray evenly; do not spray twice in the same spot or miss any spots; the use of stretcher-type sprayers or mist blowers is not recommended.

6. Do not use on weak or diseased rice seedlings caused by low temperatures, excessive rain, or heavily saline-alkali soil.

7. Do not mix with bensulfuron-methyl, pyrazosulfuron-ethyl, or similar chemicals.

8. Use with caution in hybrid seed production fields.
