The present invention relates to a composition having the pesticidal effects of an anthranilamide compound or its salt improved by an addition of a polyoxyalkylene phosphoric acid ester surfactant.
An anthranilamide compound is known to be useful for controlling a pest such as Lepidoptera, and Patent Document 1 discloses, as its formulations, various ones such as an emulsifiable concentrate, a wettable powder, a dust, water dispersible granules, etc. Further Patent Document 2 discloses a suspension concentrate containing a hydrophobic solvent, as a formulation to enhance the controlling effects of an anthranilamide compound against pests.
Many pesticides including anthranilamide compounds respectively have characteristics in the spectra and effects. On the other hand, they are inadequate In the effects against specific pests, or their residual effects are so short that the effects for a certain period cannot be expected, and in some applications, no adequate controlling effects can practically be obtained. Accordingly, it is desired to improve the controlling effects by some formulation techniques.

Kidney bean planted in a pot having a diameter of 7 cm was put in a breeding case wherein adults of serpentine leaf miner (Liriomyza trifolii) were released and permitted to lay eggs for 2 days. Thereafter, the test plant was taken out and left for 1 day, and then, a water-diluted liquid containing 100 ppm or 250 ppm of the polyoxyethylene alkyl ether phosphoric acid ester prepared in the above Example 1, was sprayed twice on each of the front and rear sides of the Kidney bean leaf by means of a hand spray. After drying in air, the Kidney bean was left to stand for 5 days in an illuminated constant temperature chamber at 25° C., whereupon the number of pupae on each leaf was counted, and the protective value was calculated by the following formula. The test was repeated twice. As the polyoxyethylene alkyl ether phosphoric acid ester, PHOSPHANOL RD-510Y, PHOSPHANOL RS-610 and PHOSPHANOL RS-710 (manufactured by Toho Chemical Industry Co., Ltd.) and ADEKA COL PS-440E (manufactured by ADEKA) were used.
For the purpose of comparison, a water-diluted liquid having no polyoxyethylene alkyl ether phosphoric acid ester added, was prepared, and spray treatment was carried out in the same manner.
The results of the test are shown in Tables 1 and 2.
Protective value (%)=(1−(the number of pupae at treated section/the number of pupae at untreated section))×100
