ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to pesticidal compositions.
BACKGROUND OF THE INVENTION
Various carbamate compounds have been used as active ingredients of pesticidal compositions; however, not all of them can exhibit satisfactory pesticidal effects and the occurrence of pests resistant to these carbamate compounds has been observed. For this reason, there has been a demand for the development of more effective pesticidal compositions.
SUMMARY OF THE INVENTION
Under these circumstances, the present inventors have extensively studied. As a result, they have found that pesticidal compositions containing as active ingredients 3,5-dichloro-1-(3,3-dichloro-2-propenyloxy)-4-[3-(5-trifluoromethylpyridin-2-yloxy)propoxy]benzene of the formula:
and at least one carbamate compound selected from thiodicarb, methomyl and alanycarb have excellent pesticidal activity and can attain the effective control of pest species which cannot be satisfactorily controlled by thiodicarb, methomyl or alanycarb and pest species which have acquired resistance to thiodicarb, methomyl or alanycarb, and further that their cooperative action is synergistic and therefore the application amount of thiodicarb, methomyl or alanycarb can be reduced as well as the development of resistance to thiodicarb, methomyl or alanycarb in various pests can be inhibited, thereby completing the present invention.
Thus, the present invention provides pesticidal compositions which comprise as active ingredients 3,5-dichloro-1-(3,3-dichloro-2-propenyloxy)-4-[3-(5-trifluoromethylpyridin-2-yloxy)propoxy]benzene (hereinafter referred to as compound A) and at least one carbamate compound selected from thiodicarb, methomyl and alanycarb (wherein the pesticidal compositions are hereinafter referred to as the present compositions).
DETAILED DESCRIPTION OF THE INVENTION
Compound A is disclosed in WO 96/11909 and can be prepared by the process described therein.
The carbamate compounds used in the present invention are specific ones each having a methyl(1-methylthioethylideneaminooxycarbonyl)amino group. Thiodicarb, methomyl and alanycarb are well known compounds as described in “The Pesticide Manual 10
th
Ed” (published by the British Crop Protection Council) on pages 982-984, 679-680 and 23-24, respectively. In the present invention, these commercially available compounds can be used. These carbamate compounds can also be produced according to the ordinary methods.

In the present compositions, the mixing ratio of compound A and the carbamate compound is usually in the range of 0.5: 99.5 to 60: 40 by weight, preferably 0.5: 99.5 to 50: 50 by weight. In particular, when the carbamate compound is methomyl or alanycarb, the mixing ratio is in the range of 0.5: 99.5 to 30: 70 by weight, more preferably 0.5: 99.5 to 20: 80 by weight. When the carbamate compound is thiodicarb, the mixing ratio is in the range of 1: 99 to 50: 50, more preferably 10: 90 to 50: 50 by weight.
The present compositions, although they may contain no other ingredients and may consist of compound A and the carbamate compound(s), can usually further contain solid carriers, liquid carriers, gaseous carriers or baits, and, if necessary, surfactants and other auxiliaries, and can take various forms of formulations, such as oil sprays, emulsifiable concentrates, wettable powders, flowables, granules, dusts, aerosols, fumigants (e.g., foggings), poison baits or microcapsule preparations.
These formulations usually contain as active ingredients compound A and at least one carbamate compound selected from thiodicarb, methomyl and alanycarb in the total amount of 0.01 to 95 wt. % for each formulation.
