ABSTRACT:

FILED OF INVENTION
The present invention relates to pesticidal compositions.
BACKGROUND OF THE INVENTION
The development of pesticides has been widely carried out for the control of many kinds of pests including agricultural and forest pests and hygienically unfavorable pests, and a wide variety of chemical agents have been put to practical use. All conventional pesticides, however, cannot be said to give satisfactory results; for example, they may lack at least one of lethal efficacy, immediate effect, and residual effect, or they may have poor results on the specific kinds of pests or on the specific growth stage of pests. Accordingly, there has been a demand for the development of more excellent pesticides.
SUMMARY OF THE INVENTION
Under these circumstances, the present inventors have concentrated on the study and consequently found that pesticidal compositions comprising 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether and 2-(2,6-difluorophenyl)-4-(2-ethoxy-4-tert-butyl-phenyl)-2-oxazoline as active ingredients, when used to control agricultural and forest pests or hygienically unfavorable pests, can have unpredictably high pesticidal efficacy and exhibit excellent immediate effect and residual effect as compared with the separate application of each compound, making it possible to solve the above problems, which leads to the present invention.
Thus the present invention provides pesticidal compositions (hereinafter referred to as the present compositions) comprising 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether (hereinafter referred to as compound A) and 2-(2,6-difluorophenyl)-4-(2-ethoxy-4-tert-butyl-phenyl)-2-oxazoline (hereinafter referred to as compound B) as active ingredients; pest control methods comprising application of the present compositions to pests or their habitats; and plant protection methods comprising application of the present compositions to plants or their neighborhood, which may be infested with agricultural and forest pests.
DETAILED DESCRIPTION OF THE INVENTION
The active ingredients in the present compositions are well known in the art; compound A (common name: pyriproxyfen) from U.S. Pat. No. 4,751,225 and compound B (common name: etoxazole) from WO 93/22297.
