Abstract

The invention discloses a combined oil-suspended injection composition used for weeding, comprising the following components by weight percent: 2-20% of mesotrione, 2-10% of nicosulfuron, 15-50% of atrazine, 5-15% of emulsifiers, 1-3% of dispersant and the balance plant oil or esters of the plant oil. The composition of the invention has good synergistic effect and has especially obvious synergistic effect on broadleaf weeds. The composition also expands the weed control spectrum, reduces the drug consumption, improves the safety of the succeeding crops and can achieve stable weeding effects in arid regions or at low temperature.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to an oil suspension composition containing mesotrione. Background technique [0002] Atrazine is a systemic selective pre-emergence and post-emergence herbicide. It is mainly absorbed by roots, with little absorption by stems and leaves. It has both soil sealing and early post-emergence herbicide effects. Grass. Atrazine has a long duration in the soil, so it is not advisable to increase the dosage of atrazine arbitrarily, and it is not suitable to apply it in particularly dry areas, so as to avoid phytotoxicity to subsequent crops. [0003] Nicosulfuron is a sulfonylurea cornfield herbicide developed by Ishihara Sangyo Co., Ltd. in Japan. It can be absorbed by the roots, stems and leaves of weeds, and can effectively control gramineous weeds, some broad-leaved weeds and sedges. Stable herbicidal effect can still be obtained under drought conditions. [0004] Mesotrione is a highly eff...
