Abstract

The invention discloses a novel anti-transpiration wetting synergistic tank mixing auxiliary agent, which is prepared from the following ingredients in percentage by mass: 30 to 65 percent of fatty alcohol, 0 to 8 percent of polyvinylpyrrolidone, 0 to 50 percent of diethylene glycol, 10 to 30 percent of ethoxylated castor oil, 5 to 20 percent of ethyl lactate and the balance of water. Through the synergistic effect of polyvinylpyrrolidone and ethoxylated castor oil, the transpiration loss of liquid drops in a high-temperature environment is effectively reduced, it is ensured that more liquid medicine reaches a target, and the deposition amount is increased by 30%-50%. Ethoxylated castor oil improves the emulsion stability of fatty alcohol in water, diethylene glycol monomethyl ether improves the overall stability of a system, and ethyl lactate solves the problem of low-temperature condensation, so that the product can be kept stable under different environmental conditions. The optimized surface active component combination significantly improves the wetting ability of the liquid medicine to a target, promotes rapid permeation of the liquid medicine, and enhances the drug effect. The pesticide dosage is reduced, the resistance problem is relieved, the national pesticide and chemical fertilizer zero growth policy is met, and remarkable environmental and economic benefits are achieved.

Description

Technical Field

[0001] The invention relates to the technical field of agricultural chemicals, and in particular to a novel anti-transpiration wetting synergistic tank mix adjuvant. Background Art

[0002] With the increasing sophistication of agriculture, tank-mix synergistic technology has become an industry hotspot. Current challenges include: the development of weed and insect resistance, which is driving increased demand for high-efficiency synergistic adjuvants; the national policy of zero growth in pesticides and fertilizers; the transfer of rural land, which is driving the development of large-scale agricultural and agricultural service companies, and the reliance of large-scale agriculture on planting and plant protection technologies to increase yields; and the promotion of new application technologies such as precision agriculture and drones. However, drone-based spraying suffers from limited water delivery and crop penetration problems. Evaporation at high temperatures prevents most droplets from reaching their targets, resulting in ineffective efficacy.

[0003] Currently, the tank-mix adjuvants on the market are divided into mineral oil, vegetable oil (including essential oils), methyl ester oil, silicone, surfactants and other types according to the active ingredients. However, they generally have defects such as severe phytotoxicity, poor wetting and permeability, and insufficient anti-transpiration performance. In particular, the lack of anti-transpiration function has become a gap in the industry and cannot meet the needs of modern precision agriculture. Summary of the Invention

[0004] The object of the present invention is to provide a novel anti-transpiration and wetting synergistic tank mix adjuvant to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a new anti-transpiration wetting synergistic barrel mix adjuvant, composed of the following components in mass percentage: 30-65% fatty alcohol, 0-8% polyvinyl pyrrolidone, 0-50% diethylene glycol, 10-30% ethoxylated castor oil, 5-20% ethyl lactate and the balance water.

[0006] Among them, polyvinyl pyrrolidone can greatly enhance the anti-transpiration effect of droplets when the spray liquid is formed, ensuring the amount of liquid deposited on the target; ethoxylated castor oil improves the emulsification stability of fatty alcohols in the diluent, making the fatty alcohols more evenly dispersed during the spraying process and improving the anti-transpiration performance of the droplets; diethylene glycol improves the stability of the entire system; ethyl lactate, as an anti-low temperature additive, helps the entire solution to be less likely to condense at low temperatures and increase the low-temperature product stability.

[0007] Preferably, the mixture is composed of the following components in percentage by mass: 47% fatty alcohol, 7% polyvinyl pyrrolidone, 8% diethylene glycol, 28% ethoxylated castor oil, 5% ethyl lactate and 5% water.

[0008] Preferably, it is composed of the following components in percentage by mass: 30% fatty alcohol, 45% diethylene glycol, 10% ethoxylated castor oil and 15% ethyl lactate.

[0009] Preferably, the mixture is composed of the following components in percentage by mass: 60% fatty alcohol, 20% ethoxylated castor oil, 15% ethyl lactate and 5% water.

[0010] Preferably, the fatty alcohol is preferably a straight-chain fatty alcohol with 8 to 12 carbon atoms, more preferably a straight-chain fatty alcohol with 10 to 12 carbon atoms; the polyvinyl pyrrolidone is preferably a K15 series product with a molecular weight of 10,000; and the ethoxylated castor oil is preferably a product with a polyethylene oxide number of 36.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention effectively reduces transpiration losses of droplets in high-temperature environments through the synergistic effect of polyvinylpyrrolidone and ethoxylated castor oil, ensuring that more liquid medicine reaches the target and increasing deposition by 30%-50%. Ethoxylated castor oil improves the emulsification stability of fatty alcohols in water, diethylene glycol monomethyl ether enhances the overall stability of the system, and ethyl lactate solves the problem of low-temperature condensation, allowing the product to remain stable under various environmental conditions. The optimized combination of surfactants significantly improves the wettability of the liquid medicine on the target, promotes rapid penetration of the liquid medicine, and enhances its efficacy. This reduces pesticide usage and alleviates resistance issues, complying with the national policy of zero growth in pesticides and fertilizers, and providing significant environmental and economic benefits.
