Background
Conventionally, various surfactants have been used in pesticide-containing compositions in order to sufficiently exhibit the effects of pesticides. For example, it is known that a pesticide-containing composition having a high effect on bipyridinium herbicides can be obtained by combining an anionic surfactant and a chelating agent (see, for example, international publication No. 95/31903). It is also known that a pesticide-containing composition having a high pesticidal effect can be obtained by blending a chelating agent with a cationic surfactant and adding another surfactant (see, for example, international publication No. 95/17817). In addition, in order to improve wettability, a nonaqueous spreading agent in which a sorbitan fatty acid ester, a polyoxyethylene alkyl ether and a polyether-modified silicone are dissolved in isopropyl alcohol has been proposed (see japanese patent application laid-open No. 2000-001404 (claims and others)). Further, Japanese patent application laid-open No. 2006-248994 discloses a non-aqueous agricultural chemical spreading agent composition containing a surfactant, a water-soluble organic solvent having a flash point of 70 ℃ or higher, and an antifoaming agent or a defoaming agent. In addition, japanese patent application laid-open No. 2006-257072 discloses a herbicide composition containing a polyoxyalkylene fatty acid ester and another nonionic surfactant. Further, jp 2008-184455 a discloses an agricultural chemical liquid formulation containing a hydrophobic agricultural chemical active compound, a specific nonionic surfactant selected from polyoxyethylene polyoxypropylene block copolymers and the like, an anionic surfactant, a specific ether compound, and 1, 3-dimethyl-2-imidazolidinone in predetermined amounts. Further, Japanese patent application laid-open No. 2002-249403 discloses an agricultural chemical efficacy enhancer containing at least one of a specific alcohol compound, a specific ether compound and a specific ester compound as an active ingredient. Further, international publication No. 2012/029893 discloses a method for producing agricultural crops, which comprises a step of applying an agricultural chemical composition to an object to be treated with an agricultural chemical original, the agricultural chemical composition comprising: at least one component (A) selected from the group consisting of a specific ethoxylate-type compound, a specific polyoxyethylene fatty acid ester, a specific polyoxyethylene sorbitan fatty acid ester, a specific (poly) glycerin fatty acid ester and a specific alkyl sugar, at least one component (B) selected from the group consisting of a specific polyoxyalkylene alkyl ether and a specific fatty alcohol, and an agricultural chemical.

[ pesticide efficacy enhancement test ]
(1) Insecticidal test
Cabbage seedlings were cultivated in 12cm pots in such a way that they reached the 10-leaf stage. 1 piece of cabbage leaves was collected and completely spread, and 30 leaves were supplied with aphids. The leaves used 3 pieces (3 reciprocal). A pesticide composition was prepared by dissolving 0.125g of an aqueous solution of Mospilan (manufactured by Nippon Caoda Co., Ltd.; active ingredient: Acetamiprid (Acetamicprid)) in 500mL of water (diluted 4000 times), and further dissolving 0.5g of the efficacy-enhancing agent composition for pesticides (diluted 1000 times) shown in tables 5 to 7. The pesticidal composition was sprayed onto the leaves on which aphids were placed in an amount of 2mL per leaf using a hand-held sprayer of the PISTOL type used in the above-described odor test. Each leaf was kept in a shallow dish, and the periphery was covered with filter paper to prevent escape. After 1 day, the number of live insects was measured, and the insecticidal ratio was calculated according to the following formula. The higher the numerical value of the pesticidal rate, the higher the pesticidal efficacy (pesticidal effect).
Insecticidal ratio (%) - (number of surviving insects in untreated area-number of surviving insects in treated area)/number of surviving insects in untreated area × 100

Suspending spore suspension (with bacterial count of 10) of Botrytis cinerea7one/mL) was spread on cucumber in a spread amount of 50L/10 a. Thereafter, the mixture was allowed to stand at 25 ℃ and 90% relative humidity to infect germs. After 3 days, Daconil 1000 (manufactured by Sumitomo chemical Co., Ltd.; effective ingredient:tetrachloroisophthalonitrile (TPN)40 mass%) 1g (diluted 1000 times), and 1g of the efficacy enhancer composition for agricultural chemicals shown in tables 5 to 7 (diluted 1000 times) were dissolved to prepare an agricultural chemical dispersion (agricultural chemical composition). The pesticide dispersion liquid was applied to the cucumber leaf surface at a spreading amount of 50L/10 a. Then, the pot was left to stand at 25 ℃ and 85% relative humidity for one week, and after that, the number of lesions was counted, and the control value was calculated using the following formula. The higher the numerical value of the control value, the higher the pesticidal efficacy (bactericidal effect).
Control value (%) { 1- (number of lesions in treated area/number of lesions in untreated area) } × 100
From the results shown in tables 5 to 7, it was confirmed that the bactericidal effect was improved by using the pesticidal composition using the efficacy-enhancing agent composition for agricultural chemicals of the present invention.

In the same manner as in the sterilization test (I), 20g of the agricultural chemical (diluted 50 times) was dissolved in 1L of water, and 10g of the efficacy-enhancing agent composition for agricultural chemicals (diluted 100 times) was further dissolved to prepare an agricultural chemical dispersion. The pesticide dispersion liquid was applied to the surface of cucumber infected with bacteria at a rate of 1L/10 a. The evaluation method of the control value was the same as that of the sterilization test (I).
From the results shown in tables 5 to 7, it was confirmed that the pesticidal effect of the pesticidal composition using the efficacy-enhancing agent composition for agricultural chemicals of the present invention can be improved even under test conditions of high concentration and low amount of sprayed water of agricultural chemicals.
