Description

Technical Field

[0001] The present invention relates to an evaporation inhibitor for a plant treatment agent, an evaporation inhibitor composition for a plant treatment agent, an efficacy enhancer composition for a pesticide, a plant treatment agent composition and a plant treatment method. Background Art

[0002] In recent years, problems affecting food supply, such as the decrease and aging of the agricultural employment population, and the increase in natural disasters affected by climate change, are increasing. In particular, improving the productivity of safe and secure food is an important issue. Against this background, for the purpose of mechanization and automation of food production, especially crop production, and reduction in the use of pesticides, the development of pesticide spreading technology using industrial multi-axis aircraft (drones) is underway. As the characteristics of drone spreading, there are the advantages of shortened operation time, reduced operations, reduced pesticide use and reduced water use due to improved spreading accuracy, and the ability to operate after sunset. On the other hand, since the spraying is carried out from a high spreading height with a low amount of water, the distance to reach crops, etc. becomes longer, so there are also issues such as evaporation of droplets during falling, significant reduction in the coverage of pesticides, and easy drift of pesticides washed away by the wind. In addition, it is not only effective in solving problems such as the decline and aging of the agricultural employment population in Japan, but also in expanding the cultivated area in dry regions where food shortages are serious, it can achieve low-water application, so there is great demand for the development of drone spraying technology.

[0003] Pesticides are used for the purpose of increasing the yield and protecting useful plants such as crops, and expelling harmful plants and pests such as weeds. Previously, a pesticide efficacy enhancer composition for fully exerting the effect of pesticides has been developed. For example, in Japanese Patent Publication No. 2012-184187, a pesticide efficacy enhancer composition is disclosed, which contains one or more compounds (A) selected from specific ethoxylate compounds, specific polyoxyethylene fatty acid esters, specific polyoxyethylene sorbitan fatty acid esters, specific (poly)glycerol fatty acid esters and specific alkyl saccharides, and one or more compounds (B) selected from alcohols having a straight or branched alkyl group with 8 to 14 carbon atoms. In International Publication No. 2018 / 173184, a pesticide efficacy enhancer composition containing (A) a specific polyoxyethylene fatty acid ester, (B) a specific aliphatic alcohol and (C) a specific fatty acid is disclosed.

[0004] On the other hand, when applying pesticides in fine droplets by aerial dispersion or the like, it is desirable that the droplets contain the pesticide at a high concentration and have a small particle size. However, since the water in such fine droplets is easy to evaporate, they may not exhibit the pesticide effect as designed, or may be further dispersed due to further miniaturization and thus may be dissipated into the surrounding environment. Therefore, it is desirable to suppress the evaporation of water in the droplets as much as possible. Japanese Patent Application Laid-Open No. 61-122202 discloses an evaporation inhibitor, characterized in that it is an evaporation inhibitor for a spray mixture of a pesticide in the form of a wax-containing aqueous dispersion or a self-emulsifying organic solvent solution and is dispersed by a low-volume method, and comprises 15 to 50% by weight of a wax or a wax mixture, 4 to 20% by weight of a nonionic and / or anionic emulsifier, 19.5 to 81% by weight of water and / or an organic solvent selected from hydrocarbons, esters and ketones having a boiling point of 70 to 280° C., 0 to 5.5% by weight of other adjuvants, and 0 to 5.0% by weight of an amine or a base. Summary of the invention

[0005] Efficient application of pesticides and other plant treatment agents leads to improved productivity of crops and other plants. As a countermeasure, there is a demand for technology that can efficiently spread pesticides and other plant treatment agents at high concentrations and low water volumes from aircraft such as drones.

[0006] The present invention provides an evaporation inhibitor for plant treatment agents, which can effectively enhance the efficacy of plant treatment agents such as pesticides, and can improve the coverage of plant treatment agents such as pesticides by applying plant treatment agents such as pesticides with high concentration and low water volume, such as by spreading them using drones.

BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Figure 1 It is a schematic diagram which shows the spreading position of the pesticide composition in Example 1 etc.

[0035] Figure 2 This is a schematic diagram showing the spreading position of the pesticide composition in Example 7. DETAILED DESCRIPTION

[0036] The evaporation inhibitor for plant treatment agents of the present invention can effectively enhance the effectiveness of plant treatment agents such as pesticides because it can inhibit the evaporation of water during spreading. In particular, it can exert the excellent coating improvement ability of plant treatment agents such as pesticides for high-concentration and low-water-volume spreading using drones.

[0037] The details of the mechanism of action of the evaporation inhibitor for plant treatment agents of the present invention are not certain, but can be considered as follows.

[0038] When spreading pesticides and other drugs applied to plants, water is generally used as a solvent and a dispersion medium, and a sprayer, a sprinkler, and other spreading devices are used to apply the target plants. For example, if it is a pesticide, the amount used is suppressed to the smallest possible amount in consideration of the impact on the environment. In order to efficiently attach to the part where the pesticide is effective, a component that improves the spreadability is sometimes added. For example, in order to make the pesticide adhere to the entire leaf surface, a method can be adopted in which the pesticide is directly attached to the entire leaf surface, or a method can be adopted in which the pesticide is attached and then infiltrated and expanded, that is, spread to cover the entire surface. In order to directly attach to the entire surface, it is necessary to increase the amount of spreading, which is wasteful and not suitable for the above purpose. In the case of spreading it, it is sufficient to use a spreading component with high infiltration and expansion, but after the pesticide is spread, before it is attached to the leaves, the solvent such as water and the dispersion medium evaporate, and it will be concentrated at the moment of attachment to the leaves, the viscosity increases, and it becomes difficult to infiltrate and expand. In particular, the falling distance, the influence of wind, and the size of the droplets (the surface area of ​​the droplets) lead to an increase in the floating time after spreading, which becomes a factor in the evaporation of solvents such as water and the dispersion medium. It can be inferred that by containing the evaporation inhibitor for plant treatment agents of the present invention, the evaporation of the solvent and the dispersion medium after spreading can be suppressed, and the high wetting and spreading properties after adhering to the leaves can be maintained. In addition, since the evaporation inhibitor for plant treatment agents of the present invention exhibits its effect in an amount that is very small compared to the content that can completely cover the surface of the droplets, it is inferred that the effect is not exhibited by covering the surface of the droplets, but by forming a complex with other components such as pesticides, etc., although the details are unclear, it forms a structure that is not easy to evaporate, thereby exhibiting the effect. In addition, since such an effect can be obtained, it is inferred that the evaporation inhibitor for plant treatment agents of the present invention can further exert this effect when using a drone with a high spreading height, a high pesticide concentration, a small spreading amount, and a wind that can be generated by itself.
