At that time, various contrivances have been made in terms of the physical properties of the preparation in order to sufficiently bring out the effect of the pesticidal drug substance, but it is currently difficult to further enhance the effect of the pesticide by devising the preparation.
Further, since the development of new pesticides is more difficult, it is of great industrial significance to further enhance the activity of existing pesticides.

Up to now, surfactants composed of various nitrogen-containing compounds such as quaternary ammonium salts, betaines and amine oxides have been known as those having an effect of enhancing the activity of agricultural chemicals (Japanese Patent Laid-Open No. 2000-242242). Sho 63-1452
No. 05). Among them, it is known that a quaternized or further polyoxyethylenated long chain amine is particularly effective.

Example 3 A third-instar larva of a planthopper was cultured, and the efficacy of the insecticide was tested by the dipping method with 10 heads in 1 section and 3 systems. The insecticidal rate was calculated in the same manner as the acaricidal rate. 50 for each of the commercially available insecticide Sumithion emulsion (50% by weight effective as MEP) and marathon emulsion (50% by weight effective as marathon)
The 00-fold diluted solution was used, and the agrochemical potency enhancer used in Example 1 was used so that the concentration in the diluted solution was 1.80% by weight. The results are shown in Tables 9 and 10.

Example 4 Cucumber Botrytis cinerea (Botrytis) which is a fungicide-resistant bacterium
cinerea) spore suspension (10 ⁷ / ml) was sprinkled on cucumber seedlings (developing 3 true leaves) 10 ml per pot, 25
It was allowed to stand for 1 day at 90 ° C and 90% relative humidity.

Then, a commercially available fungicide, Benlate wettable powder (50% by weight of active ingredient as benomyl) was diluted 5000 times with a 60-fold diluted solution of the active ingredient used in Example 1, and then 1
Sprayed 5 ml per pot. After that, it was allowed to stand at 25 ° C and 85% relative humidity, the number of lesions was counted, and the control value for the untreated plot was calculated by the following formula. The results are shown in Tables 11 and 12.
