ABSTRACT:
TECHNICAL FIELD
The present invention relates to pesticidal compositions and pesticidal methods.
BACKGROUND ARTS
Hitherto, pesticides for controlling various pests such as agricultural and forestry pests, ectoparasites of animals and hygienically unfavorable pests have been developed. However, it cannot be said that old pesticides exhibit satisfactory effects in the practical use wherein pests in various growth stages exist.
The present invention provides pesticidal compositions and pesticidal methods which are very effective for controlling the pests in agricultural and forestry fields, such as whiteflies, and further effective for controlling ectoparasites of animals, hygienically unfavorable pests and the other various pests.
DISCLOSURE OF THE INVENTION
According to the present invention, a pesticidal composition comprising 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether and (E)-1-(2-chlorothiazol-5-ylmethyl)-3-methyl-2-nitroguanidine as active ingredients and a pesticidal method comprising utilizing 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether and (E)-1-(2-chlorothiazol-5-ylmethyl)-3-methyl-2-nitroguanidine together give satisfactory effect in practical use.
Namely, the present invention provides a pesticidal composition (hereinafter, referred to as the present pesticidal composition) comprising 4-phenoxyphenyl 2-(2-pyridyloxy)propyl ether (hereinafter, referred to as pyriproxyfen) and (E)-1-(2-chlorothiazol-5-ylmethyl)-3-methyl-2-nitroguanidine (hereinafter, referred to as chlothianidine) as active ingredients and a pesticidal method (hereinafter, referred to as the present pesticidal method) comprising utilizing pyriproxyfen and chlothianidine together.
Pyriproxyfen used in the present pesticidal composition and the present pesticidal method is a compound described in U.S. Pat. No. 4,751,225 specification and chlothianidine is a compound described in U.S. Pat. No. 5,034,404 specification. These compounds can be produced according to the descriptions in these specifications.
The combination of pyriproxyfen and chlothianidine produces a synergistic effect that is clearly larger than a sum of the sole effect of each compound as shown in the test examples described later.
In the present pesticidal composition and the present pesticidal method, pyriproxyfen and chlothianidine are combined and utilized in a ratio that can produce a synergistic effect. It is usually 0.01 to 30 parts by weight of chlothianidine, preferably 0.5 to 10 parts by weight based on 1 part by weight of pyriproxyfen.
The present pesticidal composition and the present pesticidal method can be applied for controlling various pests such as agricultural and forestry pests, ectoparasites of animals and hygienically unfavorable pests.
