A herbicide that does not harm cotton

Cotton needs to be weeded frequently, and weeding is inevitable with some herbicides. So what are the herbicides that don't hurt cotton? Let's take a look at the application of cotton herbicides.

1. Cotton herbicide

1. When weeding cotton fields, herbicides such as trifluralin, lasso, acetochlor, butachlor, diuron and dinochlor can be selected.

2. When weeding stems and leaves, you can choose herbicides such as stable kill, fine stable kill, cover grass, grass gram, gram wu zong, glyphosate, etc.

3. Before cotton sowing, 48% trifluralin emulsifiable concentrate can be used 100 ml-150 ml per mu mixed with 50 kg of water and sprayed evenly, and mixed with soil immediately after application.

4. Cotton after sowing before emergence, you can choose 43% lasso emulsifiable concentrate 200 ml-300 ml per mu mixed with 50 kg of water evenly sprayed.

5. After cotton seedlings grow to 4 leaves, they can be treated with 50 ml of 15% Wenshadi EC or 50 ml of 12.5% Gai Cao Neng EC mixed with 50 kg of water.

II. Methods for identifying cotton herbicides

1. Don't listen to advertisements. To use their own basic knowledge of various herbicides to identify, such as pendimethalin to Solanum nigrum (black beans, wild grapes) control effect is poor, but some advertising pendimethalin propaganda on the nominal kill black beans, not to say whether the product is false, at least exaggerated propaganda, please cotton farmers to avoid.

2. Query tags. Each pesticide label must have three certificates, otherwise it is unqualified. The easiest way to check is the pesticide registration certificate. Now pesticides generally only have the registration certificate at the beginning of PD. If the instructions, address, content, etc. are different, it must be counterfeit pesticides.

3. Look at the exterior. Look at the batch number and production date of the pesticide to see if it expires. If the production date is after January 1,2018, the label must have a QR code. A scan with mobile phone WeChat can display the registration certificate, content, common name, manufacturer and other information, otherwise it is a problematic herbicide. See if there are lumps in the bucket (bottle), whether there are too many precipitated things, too many lumps and precipitated things are problematic herbicides, inconvenient to buy.

Cotton herbicides need to be carefully selected and purchased, otherwise it will affect the normal growth of cotton and cause cotton yield reduction. But cotton herbicides should also be used, otherwise there will be too dense grass, affecting the normal growth of cotton.
