Technical Field
The invention relates to the field of synergistic additives, in particular to a synergistic additive for improving the drug effect of a weeding pesticide and a preparation method thereof.
Background
The existing weeding pesticide preparation mainly acts on target plants (weeds) to be cleared in a spraying mode in the using process, and the existing weeding pesticide is gradually prepared according to the characteristics of the target plants to be cleared, so that the pesticide cannot have a strong destructive effect on normal crops, but the general properties of plant histiocytes are not specifically improved, the pesticide applying effect is not ideal or the using amount is more than the normal using amount, the cost is increased, and the harm is caused to the normal crop environment and a pesticide applying operator. In order to solve the problem, before the weeding pesticide is used, a synergistic additive for improving the binding force of the pesticide and the target plant is generally added to improve the pesticide effect of the pesticide on the target plant.
The prior synergistic auxiliary agent for the herbicide preparation is mainly various permeation enhancers, aiming at accelerating the permeation of the pesticide into the plant, so that the synergistic auxiliary agent can produce undifferentiated permeation to the target plant and normal crops. Although the killing effect of the target plant can be improved within a short time, under the strong permeation enhancing effect, the osmotic pressure of cell water of the target plant and the normal crop can be influenced, after the method is applied for a period of time, the osmotic absorption of pesticide by the target plant cell is deteriorated, the drug effect is reduced, and meanwhile, the normal crop withers due to the water loss of the cell, so that the growth, the maturity and the fruit quality of the normal crop are influenced.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: overcomes the defects that the target plants are deteriorated in drug property and normal crop growth is influenced after the application for a period of time, which are caused by the single permeation-enhancing action of the conventional synergistic additive, and provides the synergistic additive for enhancing the drug effect of the herbicide, which maintains the normal osmotic pressure of plant cells, and the preparation method thereof.

The synergistic auxiliary agent comprises 90% of trimethylglycine, 3.5% of calcium dodecanesulphonate, 3.0% of azone and the balance of solvent oil.
The synergistic auxiliary agent comprises, by weight, 10% of trimethylglycine, 1.5% of calcium dodecanesulphonate, 2.0% of azone and the balance of solvent oil.

The effective component proportion is preferably that the synergistic auxiliary agent component comprises 45 percent of trimethylglycine, 3.5 percent of dodecane basic calcium sulfonate, 2.0 percent of azone and the balance of solvent naphtha.
The synergistic auxiliary agent comprises 50% of trimethylglycine, 2.5% of calcium dodecanesulphonate, 2.5% of azone and the balance of solvent oil.
Specifically, the solvent oil is one or more than two mixed oils of soybean oil, corn oil, castor oil and rapeseed oil. The vegetable oil is selected as the solvent oil, has good affinity with the outside of the plant, is rain-wash resistant, and is relatively safe to normal crops.
The synergistic additive for improving the drug effect of the weeding pesticide and the preparation method thereof are characterized in that 1.5-3.5% of basic calcium dodecanesulfonate and 2.5-4.5% of azone are mixed and uniformly stirred in a 45-degree water bath according to the mass percentage, then the mixed solution is added into 10-90% of trimethylglycine while being stirred, the solvent oil is used for supplementing the residual amount, and the synergistic additive is obtained after filtration.
The synergistic auxiliary agent is used as an infiltration-assisting synergist and is prepared from the following components in a mass ratio of 1: and 5, adding the herbicide into the herbicide, and uniformly mixing for use.
