What is broad-leaved grass?

Broad-leaved grass, also known as dicotyledonous weeds, embryo has two cotyledons, herbaceous or woody, leaf veins reticulate, leaf blade wide, petiolate.

According to the life length of broadleaf grass, it can be divided into annual weeds and perennial weeds:

Annual broad-leaved weeds are seed propagation, and the germination depth in the soil is 0-5 cm. When using herbicides, the germinated weeds in shallow soil can be effectively controlled, such as Chenopodium, amaranth, Cardamine, wild watermelon seedlings and so on.

For the weeds germinated in the deep soil layer, because the seeds are below the drug layer, it is difficult to control with soil surface treatment herbicides, such as Xanthium sibiricum, duck metatarsus, abutilon and so on.

It can be removed with herbicides such as fluoxifen and prednisone, and can be tried in a small sesame field before use, and then used in a large area after there is no problem. The specific use of the herbicide should refer to the manual or consult the seller.

Among them, herbicide is relatively safe and has a better control effect on sedge.

Soil sealing treatment before seeding or transplanting of sesame can effectively reduce the occurrence of Gramineae weeds and broad-leaved weeds in the field.

Jinduer 960g / L Metolachlor EC was registered for pre-seedling spraying soil treatment in sesame field after sowing to control annual Gramineae weeds and some broad-leaved weeds. The recommended dosage of pure medicine per hectare is 720,936g.

After sowing sesame seeds before seedling or before transplanting, herbs such as herbaceous herbs can also be used for soil closure treatment. Field grasses, broad-leaved grasses and sedges can be controlled by spraying 90% high-efficiency herbaceous Dan EC 110-140 ml per mu and adding 40-50 kg of water.
