Common cornfield herbicide blends include acetochlor and atrazine, oxazin and atrazine, etc. What are the types of cornfield herbicide blends? Their respective characteristics are What? The following is a detailed analysis of the Chinese pesticide network .

1. Acetochlor and atrazine 1:1 mixture: The earliest production of this herbicide mixture is E-A mixture and acetaminophen suspension. It can be used for pre-emergence of corn after planting and early post-maize seedling control. Weeds and broadleaf weeds are safe for corn and crops. Similar products are butachlor + acetochlor + atrazine, butachlor + atrazine, alachlor + acetochlor + atrazine, metolachlor + atrazine, propisochlor +莠津津, etc.

2. Acetochlor and atrazine 2:3 mixture: This herbicide mixture can be used to control the annual grass weeds and broadleaf weeds in the corn field in the early stage after corn sowing, and in the early stage of corn seedlings, which is safe for corn; Safety in the post-wheat wheat may be reduced in particularly dry years. The similar performance varieties include chloromeron + acetochlor + atrazine, which can greatly improve the safety of the later glutinous wheat, but can not be used after corn seedlings.

3. Prochloraz and indomethacin mixture: It can effectively control annual grass weeds and broadleaf weeds in corn fields. In the post-emergence application, the herbicidal effect is stable after the sowing, and the degree of the affected by the moisture is small. However, when the rain is large, the leaching will reduce the herbicidal effect. In the corn growing season, the corneal can be induced by adverse environmental conditions such as high temperature and drought. harm.

4. Nicosulfuron and atrazine mixture: It is an ideal herbicide mixture, which can not only effectively control a variety of annual weeds, but also prevent perennial grass weeds and sedge weeds. , safe for corn and crops. However, it can not be mixed with organophosphorus pesticides before and after use, and can be mixed with pyrethroid insecticides.

5. Acetochlor, atrazine and paraquat mixture: both exogenous and closed herbicidal effects, can effectively control a variety of weeds in corn fields during corn growth period. There are many similar products, and there are also herbicide mixtures that replace paraquat with glyphosate.
