Description

Technical Field

[0001] The present invention relates to the technical field of agricultural chemicals, and in particular to a novel insecticide-enhancing tank-mix adjuvant. Background Art

[0002] With the increasing sophistication of the agricultural industry and the excessive use of pesticides in China, tank mix synergy has become a hot topic in the industry in recent years. The main reasons are as follows:

[0003] The development of weed resistance and insect resistance has led to an increasing demand for synergistic tank-mix adjuvants.

[0004] The country's policy of zero growth in pesticide and fertilizer production has prompted the industry to seek more efficient adjuvants to reduce pesticide use. Rural land transfer has fostered the development of large-scale agricultural and agricultural service companies. The key to large-scale agricultural development lies in increasing yields through planting and plant protection technologies, which places higher demands on the performance of tank-mix adjuvants.

[0005] The promotion of precision agriculture and new application technologies, such as the large-scale use of drones, requires suitable tank-mix adjuvants to ensure the effectiveness of the agents.

[0006] Currently, the existing technology uses mineral oil adjuvants to block the pest's spiracles, suffocating the insects and killing them with physical insecticides, which are widely used on citrus crops. However, this mineral oil adjuvant has serious pesticide damage issues that are difficult to avoid during use, resulting in substantial economic losses for end-user farmers each year. Furthermore, some existing surfactant-based tank-mix adjuvants, such as sorbitan fatty acid ester surfactants, have poor low-temperature stability, making them inconvenient to use in low-temperature environments, limiting their scope of application. Therefore, there is an urgent need for a tank-mix adjuvant product that has a similar physical insecticide mechanism but is safer and easier to use at low temperatures. Summary of the Invention

[0007] The object of the present invention is to provide a novel insecticide synergistic tank mix adjuvant to solve the problems raised in the above background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a novel insecticide-enhancing barrel-mix adjuvant, composed of the following components in mass percentage: sorbitan fatty acid ester: 60-75%, triethylene glycol monobutyl ether: 4.5-9%, dimethyl adipate: 0-10%, N,N-dimethyldecylamide: 0-10% and diethylene glycol: 0-20%.

[0009] Preferably, the invention is composed of the following components in percentage by mass: sorbitan fatty acid ester: 65%, triethylene glycol monobutyl ether: 5%, dimethyl adipate: 7%, N,N-dimethyldecylamide: 5% and diethylene glycol: 18%.

[0012] A preparation method of a novel insecticide synergistic barrel-mix adjuvant comprises the following steps: weighing sorbitan fatty acid ester, triethylene glycol monobutyl ether, dimethyl adipate, N,N-dimethyldecylamide and diethylene glycol in proportion, mixing the mixture, and stirring the mixture to obtain the novel insecticide synergistic barrel-mix adjuvant.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The present invention utilizes the synergistic effect of dimethyl adipate, triethylene glycol monobutyl ether, N,N-dimethyldecylamide, and diethylene glycol to lower the freezing point of the sorbitan fatty acid ester surfactant, significantly improving ease of use at low temperatures while maintaining the product's physical insecticide mechanism of suffocating pests by blocking their spiracles. This improves ease of use compared to similar products, particularly addressing the inconvenience of use at low temperatures. DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] The invention provides a novel insecticide synergistic barrel-mix adjuvant, which is composed of the following components in percentage by mass: 60-75% of sorbitan fatty acid ester, 4.5-9% of triethylene glycol monobutyl ether, 0-10% of dimethyl adipate, 0-10% of N,N-dimethyldecylamide and 0-20% of diethylene glycol.

[0017] A preparation method of a novel insecticide synergistic barrel-mix adjuvant comprises the following steps: weighing sorbitan fatty acid ester, triethylene glycol monobutyl ether, dimethyl adipate, N,N-dimethyldecylamide and diethylene glycol in proportion, mixing the mixture, and stirring the mixture to obtain the novel insecticide synergistic barrel-mix adjuvant.

[0018] Example 1:
