Wholesale Industrial Grade Chemical Powder Pendimethalin Cas 40487-42-1 Pesticide Herbicide Pendimethalin 96%, 98%TC

Pendimethalin is a herbicide used for pre-seedling closure, mainly absorbed by the young shoots, young stems, and root systems of weeds, inhibiting cell division of young shoots and secondary root meristem tissues, thereby hindering the growth of weed seedlings and leading to weed death. Its application method is mainly spray treatment of soil. After application, dimethalin is easy to be adsorbed by soil particles, and will not become ineffective with water leaching to the deep soil. The duration of effect is moderate, generally 45-60 days. The higher the soil moisture content after pesticide application, the better the weed control effect, but the weed control effect is poor under drought conditions.

Sinobio Pendimethalin 96%, 98% CAS 40487-42-1

Product Name: Pendimethalin 96%TC
CAS NO.: 40487-42-1
Molecular formula: C13H19N3O4
Molecular weight: 281.31

EINECS: 254-938-2

Pendimethalin is a dinitrotoluidine herbicide, belonging to a low toxicity herbicide. It mainly inhibits the division of meristem cells and does not affect the germination of weed seeds. Instead, it acts after the young buds, stems, and roots absorb the herbicide during the germination process of weed seeds. The absorption site of dicotyledonous plants is the hypocotyl, while monocotyledonous plants are young buds. The symptom of its damage is that the young buds and secondary roots are suppressed to achieve the purpose of weeding.

Usage: Suitable for corn, soybean, peanut, cotton, vegetables (cabbage, celery, carrot, onion, garlic, etc.)
after sowing soil treatment before seedlings and orchard to prevent barnyard grass, cow's weed and
other annual grasses and broad-leaved weeds.
