Embodiment 1

[0038] Example 1: Mix 7 parts of tembotrione, 13 parts of chlorotoluron, 8 parts of lignosulfonate, 12 parts of sodium lauryl sulfate and 60 parts of diatomaceous earth, stir evenly in a stirring tank, and After pulverizing and mixing uniformly, the wettable powder of the herbicidal composition of the present invention is obtained.

Embodiment 2

[0039] Example 2: Mix 10 parts of tembotrione, 15 parts of chlorotoluron, 15 parts of nonylphenol polyoxyethylene ether, 10 parts of saponin powder, 40 parts of diatomaceous earth, and 10 parts of sodium sulfate, and stir evenly in a stirring tank , after passing through a jet mill and mixing evenly, the wettable powder of the herbicidal composition of the present invention is obtained.

Embodiment 3

[0040] Example 3: Mix 5 parts of tembotrione, 20 parts of chlorotoluron, 11 parts of naphthalenesulfonate formaldehyde condensate sodium salt, 15 parts of alkylnaphthalenesulfonate and 49 parts of white carbon black, and stir evenly in a stirring tank , after passing through a jet mill and mixing evenly, the wettable powder of the herbicidal composition of the present invention is obtained.

Abstract

The invention relates to weeding composition containing tembotrions and chlortoluron. A preparation of the weeding composition contains tembotrions and chlortoluron at a ratio of parts by weight of (55:1): (1:50), the total part by weight of effective components in the weeding composition preparation accounts for 1%-60% of the total part by weight of the whole preparation, and the weeding composition can be prepared to form pesticide preparation formulations such as wettable powder, a suspending agent, missible oil, microemulsion, an emulsion in water, a granule and a water dispersible granule. The weeding composition has a remarkable synergistic effect, the persistent effect of a single dosage of each component is improved, herbicide resistance of weeds is remarkably delayed, the repeated use times of herbicide, the herbicide use quantity and the agricultural cost are reduced, and the weeding composition is safe to crops, is easily decomposed in the environment after the lasting period, improves safety of next-stubble crops and has significance on ecological environmental protection.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing tembotrione and chlorotoluron. Background technique [0002] Triketone is a new type of triketone herbicide, which is also an HPPD inhibitor, and is mainly used for weeding in corn fields. Its chemical structural formula is: [0003] . [0004] Chlorotoluron, chemical name N-(3-chloro-4-methylphenyl)-N',N'-dimethylurea, is a selective systemic conduction urea herbicide. Chlorotoluron is mainly absorbed through the root system of plants, and has contact killing effect on leaves. It is an electron transport inhibitor of plant photosynthesis. Mainly used for wheat, barley, corn, highland barley fields, control of A. arvensis, bluegrass, wild oats, chickweed, cow chickweed, tongue grass, foxtail, crabgrass, barnyardgrass, amaranth, iron amaranth, purslane Annual weeds such as , fudica, quinoa, cocklebur, and pona have some effe...
