Abstract

The invention relates to a herbicide composition containing pendimethalin, oxadiazon and chlortoluron. The herbicide composition is characterized in that the weight ratio of the pendimethalin to the oxadiazon to the chlortoluron preferably is 1-75:1-30:1-75 and most preferably is 3-9:2-7:2-8. The herbicide composition has the synergistic effect.

Description

technical field [0001] The invention belongs to the field of pesticide herbicide compounding, and specifically relates to a ternary compound herbicide composition containing pendimethalin, oxadiazone and chlorotoluron and its application. Background technique [0002] Pendimethalin, other names: Pendimethalin, Shitianbu, Bicaotong, is an aniline herbicide developed by BASF, and its chemical name is: N-(1-ethylpropyl)- 2,6-Dinitro-3,4-dimethylaniline. Its chemical structural formula is as follows: [0003] [0004] The mechanism and characteristics of pendimethalin are mainly to inhibit the division of meristem cells, and do not affect the germination of weed seeds. Instead, it works after the young shoots, stems and roots absorb the drug during the germination process of weed seeds. Dicotyledons The plant absorption part is the hypocotyl, and the monocot plant is the young shoot. Symptoms of its damage are suppression of young shoots and secondary roots. [0005] Oxad...
