What precautions should be taken for chemical weed control in corn fields?
What should be noted when using chemical weed control in corn fields? Please explain. Currently, chemical weed control in corn fields accounts for about 70% of the corn planting area. Most of the herbicides used in production are atrazine plus acetochlor or their compound formulations. However, because atrazine has a long residual effect and poses a threat to the safety of subsequent crops, it is not...

What precautions should be taken when applying herbicides to corn seedlings?
What should be noted when applying herbicides to corn seedlings? Here is an introduction to chemical weed control technology in corn fields, which saves labor, saves effort, requires low input, and delivers high benefits. In recent years, the area where post-emergence herbicides for corn are applied in China's corn-producing regions has been expanding year by year. Because some applicators lack adequate application skills, some fields have experienced herbicide damage of varying degrees and...

What is the best method for weed control at the corn seedling stage
What method is used for weed control in corn seedlings? Here is an introduction. For weed control in corn seedlings, you can refer to the following points: 1. Correctly choose a post-emergence herbicide: In experiments in recent years, herbicides with relatively good post-emergence weed control effects in corn include Gengjie, Qiancenghong, Miaohoubao, etc. before the corn reaches 5 leaves; after 8-10 leaves, when the plant height reaches 60 cm, ...

How to correctly apply herbicides during the maize seedling stage
How should herbicides be applied to maize seedlings? Please give guidance. For post-emergence chemical weed control in maize, herbicides must be strictly selected and mixed and applied according to the instructions. In plots with severe weeds, the dosage may be increased by 15-20% above the rate stated in the instructions. Method: for foliage treatment, it must be done before maize reaches the 6-leaf stage and before weeds reach the 2...

What are the precautions for chemical weed control in rapeseed?
What should be noted when using chemical weed control in rapeseed? Please give guidance. For chemical weed control in rapeseed, the higher the temperature, the faster the effect. The best control effect is achieved during the vigorous growth period of weeds (before the 3-4 leaf stage), that is, about 20 days after rapeseed transplanting. 1. It is strictly prohibited to use herbicides banned by the state. Such as metsulfuron-methyl, chlorsulfuron, tribenuron-methyl and their compound formulations...

How to carry out chemical weed control in rice seedling beds
How is chemical weed control used in rice seedling beds? Please give an introduction. Chemical weed control in rice seedling beds saves labor, saves effort, and gives good results. However, in production, if the method of use is improper, it will cause herbicide damage, and in severe cases the seedlings must be destroyed and re-raised. Therefore, chemical weed control in seedling beds must master the following use techniques: different seedling-raising methods require different selected herb...
