Problems solved by technology

However, the weeds in the wheat field are mainly gramineous weeds and broad-leaved weeds, and the overall control effect of the compound herbicide of dicamba and dimethyltetrachloride is relatively low, while the control effect of pinoxaden on grassy weeds excellent

Embodiment 1

[0048] Get 2% of dicamba, 5% of dimethyltetrachlor, 13% of pinoxaden, 5% of sodium lignosulfonate, 6% of sodium dodecylbenzenesulfonate, and add kaolin to 100% by weight. The raw materials are pre-mixed, and then added to an ultrafine airflow mill equipped with a freeze dryer for ultrafine pulverization until the particle size is 5-10 microns, and the compound herbicidal composition is obtained, wherein dicamba, dimethyltetrachloride and azole The mass percent content of the triclofenac is 20%, and the dosage form of the compound herbicidal composition is a wettable powder.

Embodiment 2

[0050] Get 1% of dicamba, 10% of dimethyltetrachlor, 19% of pinoxaden, 3% of calcium lignosulfonate, 5% of sodium lauryl sulfate, and add diatomaceous earth to 100% by weight. The raw materials are pre-mixed, and then added to an ultrafine airflow mill equipped with a freeze dryer for ultrafine pulverization until the particle size is 5-10 microns, and the compound herbicidal composition is obtained, wherein dicamba, dimethyltetrachloride and azole The mass percent content of the three of mecloclodin is 30%, and the dosage form of the compound herbicidal composition is a wettable powder.

Embodiment 3

[0052] Take dicamba 5%, dimethyltetrachlor 15%, pinoxaden 30%, sodium lignosulfonate 8%, sodium dodecylbenzenesulfonate 4%, xanthan gum 5%, ethylene glycol 2% , add water to 100% by weight, add the above substances into the grinder in the order of water, sodium lignosulfonate, sodium dodecylbenzenesulfonate, dicamba, dimethyltetrachloride, and pinoxaden and grind for 4 hours , and then add xanthan gum and ethylene glycol to grind for 30 minutes to obtain a compound herbicidal composition, wherein the mass percentage of dicamba, dimethyltetrachlor and pinoxaden is 50%, and the compound herbicidal composition The dosage form of the substance is a suspension.

Abstract

The invention discloses a compound weeding composition. Effective components of the compound weeding composition include dicamba, agroxone and pinoxaden, wherein a weight ratio of dicamba to agroxone to pinoxaden is 0.5-5: 1-15: 1-30; besides, the compound weeding composition also contains a dispersing agent, an emulsifier, a wetting agent, an antifreezing agent, a thickening agent, a disintegrating agent, a binder, filler, a solvent and other auxiliaries; the dosage form of the compound weeding composition can be wettable powder, suspending agent, water dispersing granules and emulsion oil. The weeding effect of the compound weeding composition is significantly improved by comparing with that of single dosage, and the compound weeding composition can be applied to prevention and elimination of broad-leaf weed, nutgrass flatsedge and grassy weed in wheat fields; thus the compound weeding composition can enlarge herbicide controlling spectrum, improve prevention effects, retard weed resistance, reduce consumption of dicamba, decrease using cost, and improve wheat safety.

Description

technical field [0001] The invention belongs to the technical field of pesticides, especially the field of herbicides. Specifically, it relates to a compound herbicidal composition containing three active ingredients of dicamba, dimethyltetrachlor and pinoxaden. The herbicidal composition can be applied to Weeding in a wheat field. Background technique [0002] Wheat is the main food crop in our country. Grass is very common in wheat fields. Many farmers are worried that weeds will affect the yield of wheat. In recent years, with the continuous expansion of wheat planting area, weed damage is also increasing. The resulting economic loss ensures more stable growth of wheat and reduces labor intensity. At the same time, chemical weeding has been gradually accepted by people because of its convenience, quick effect, and long control time. [0003] In recent years, with the increase of herbicide varieties and the widespread promotion of chemical control technology in agricultur...
