Description

  The present invention relates to a novel agrochemical efficacy enhancer composition and an agrochemical composition containing the same.

  Agrochemicals including insecticides, fungicides, herbicides, acaricides, plant growth regulators are used in dosage forms such as emulsions, wettable powders, granules, powders, and flowables. At that time, in order to sufficiently bring out the effect of the raw material of the agricultural chemical, various devices have been made on the physical properties of the preparation. However, it is difficult to further enhance the effect of the agricultural chemical by the device on the preparation. In addition, since it is more difficult to develop new pesticides, it is highly meaningful in industry to further enhance the activity of existing pesticides.

So far, surfactants composed of various nitrogen-containing compounds such as quaternary ammonium salts, betaines and amine oxides are known as those having an effect of enhancing the activity of agricultural chemicals (Patent Document 1). Of these, quaternized or further polyoxyethylenated long chain amines are also known to be particularly effective.

Things are obtained. Some of this type are commercially available. For example, ethylene oxide adducts (2 mol, 5 mol, 10 mol adducts) of coconut oil fatty acid monoethanolamide are available as Amidette 2C, 5C, 10C from Kawaken Fine Chemical Co., Ltd. Each is commercialized.

  In the same manner as in the above method, fatty acid dialkanolamide and its alkylene oxide adduct can be obtained by using diethanolamine instead of monoethanolamine. The compound of the general formula (I) can also be obtained by using isopropanolamines instead of the ethanolamines.

  EXAMPLES The present invention will be described below with reference to examples, but the present invention is not limited to these examples.

Example 1
Various agrochemical efficacy enhancer compositions shown in Tables 2 and 3 using the compounds shown in Table 1 and, if necessary, surfactants and chelating agents shown in Tables 2 and 3 (hereinafter abbreviated as active ingredients). Was prepared.

  The above active ingredients were dissolved in ion-exchanged water so that each was diluted to 0.2% by weight. Using the obtained 0.2% by weight diluted solution, a commercially available herbicide, a round-up solution (effective amount 41% by weight as glyphosate isopropylamine salt), a Bambell-D solution (effective content 5MD by weight as MDBA dimethylamine salt) ) And Herbiece aqueous solvent (effective weight 20% by weight as bialaphos) were diluted 300 times to obtain three kinds of agrochemical compositions for each active ingredient.

  For the greenhouse test, the seeds of barley are seeded and germinated in a pot with an inner diameter of 12 cm containing soil mixed with 7: 2: 1 (weight ratio) of fertilized soil and river sand collected from paddy fields. In order to increase the uniformity of individuals between pots, pots with abnormal growth are discarded. A pot in which the plant height of the bark was grown to about 18 cm was used for the test. The pesticide composition is sprayed using a spray gun (Iwata Painter Industries, RG type) at a rate equivalent to 10 liters / earl so that it is evenly applied to the whole bark beetle in the pot and has a herbicidal effect. evaluated.

  The evaluation of the herbicidal efficacy was measured on the 10th day after the spraying treatment, and expressed as a percentage of the herbicidal activity based on the above-ground raw weight of the untreated area (see the following formula).

  Tables 4 to 5 show the herbicidal ratio of each agricultural chemical composition.

Example 2
An adult Kanzawa spider mite was placed on a green bean leaf disc in 30 cultivars in 3 groups, and then cultured at 24 hr 25 ° C. Thereafter, the entire leaf disk was immersed in the test solution for 5 seconds, taken out from the test solution and allowed to stand for 48 hours at 25 ° C., and the miticide rate was determined based on the case of no treatment (see the following formula). Nissoran wettable powder (effective 10% by weight as hexithiazox) and osadan wettable powder 25 (effective content 25% by weight as fenbutasine oxide) are used as miticides. Were the same as those used in Example 1. The concentration of the active ingredient of the efficacy enhancer for agricultural chemicals was adjusted to 0.1% by weight. Moreover, it carried out similarly also when not using an efficacy enhancer. The results are shown in Tables 6-7.

Example 3
Immerse the test solution over the whole leaf disk of green beans for 5 seconds, take it out from the test solution, air-dry it, place it on the leaf disk, and incubate 10 third-instar larvae of the planthopper on a leaf disk for 10 days. The number of dead planthoppers was examined with the naked eye, and the efficacy test for insecticides was conducted. The test was repeated three times, and the insecticidal rate was determined in the same manner as the acaricidal rate. As insecticides, a commercially available demyrin wettable powder (23.5 wt% effective as diflubenzuron) and Abroad wettable powder (25.0 wt% effective as buprofezin) were used in a 2000-fold dilution to increase efficacy for agricultural chemicals. Was used in Example 1 so that the concentration in the diluted solution was 0.1% by weight. The results are shown in Tables 8-9.

Example 4
Spore suspension (10 ⁷ / ml) of cucumber gray mold fungus (Botrytis cinerea), a fungicide-resistant fungus, is sprayed onto cucumber seedlings (3 leaf development) at 25 ° C per pot. And left to stand at 90% relative humidity for 1 day.

  Thereafter, a commercially available bactericide, benrate wettable powder (effective weight 50% by weight as benomyl) was diluted 2000 times with a 2500-fold diluted solution of the active ingredient used in Example 1 and sprayed at 5 ml per pot. . Thereafter, the mixture was allowed to stand at 25 ° C. and 85% relative humidity, the number of lesions was counted, and the control value for the untreated area was calculated by the following formula. The results are shown in Tables 10-11.

  Examples 1 to 4 show tests comparing the efficacy of the agrochemical efficacy enhancer of the present invention with the case where a general tertiary amine or cationic surfactant is used as an agrochemical efficacy enhancer (comparative product). . As is clear from Tables 4 to 11, the efficacy enhancer for agricultural chemicals of the present invention was remarkably effective and was at a practical level, but the comparative product showed a slight increase in efficacy of agricultural chemicals, but at a practical level. There was no effect. Therefore, it can be seen that the efficacy enhancer for agricultural chemicals of the present invention specifically enhances the efficacy of agricultural chemicals compared to general tertiary amines or cationic surfactants.

Example 5
A round-up solution (41% by weight of active ingredient) is used as a herbicide, and active ingredient 7, active ingredient 18 and active ingredient 25 of Example 1 are used as efficacy enhancers, and these are used in the amounts shown in Table 12. The same test as in Example 1 was performed. The results are shown in Table 12. In Table 12, “Agrochemical substance” means an active ingredient of a herbicide.
