Description

FIEDL OF THE INVENTION
The present invention relates to a pesticidal emulsifiable concentrate. More specifically, it relates to a pesticidal emulsifiable concentrate comprising pyridalyl as an effective ingredient.
BACKGROUND OF THE INVENTION
Pyridalyl, i.e., 2,6-dichloro-4- (3, 3- dichloroallyloxy) phenyl 3-[5- (trifluoromethyl) -2- pyridyloxylpropyl ether, represented by the formula (1):
Cl (1) _N ~~
F3C Cl 0) Cl has been known in W096/11909 as an effective ingredient of a pesticide. Further, a pesticidal emulsifiable concentrate comprising pyridalyl as an effective ingredient has also been disclosed in W096/11909.
OBJECTS OF THE INVENTION
However, the pesticidal emulsifiable concentrate comprising pyridalyl as the effective ingredient disclosed in Preparation Example 1 of WO096/11909 has not always
' sufficient emulsion stability depending upon conditions, when it is diluted with water. Then, it 1s desired to develop a pesticidal emulsifiable concentrate which comprises pyridalyl as an effective ingredient, and is excellent in emulsion stability.
An object of the present invention is to provide a pesticidal emulsifiable concentrate which comprises pyridalyl as an effective ingredient, and is excellent in emulsion stability upon dilution with water.
This object as well as other objects and advantages of the present invention will become apparent to those skilled in the art from the following description.
SUMMARY OF THE INVENTION
The present inventors have studied intensively to obtain a pesticidal emulsifiable concentrate which comprises pyridalyl as an effective ingredient, and is excellent in emulsion stability upon dilution with water.
As a result, they have found that a pesticidal emulsifiable concentrate containing an aromatic hydrocarbon as a solvent, and a polyoxyethylene polyoxypropylene polyarylphenol and an alkylarylsulfonate as surfactants can attain the desired object. Thus, the present invention has been completed.
That is, the pesticidal emulsifiable concentrate of the present invention comprises pyridalyl, a a A 3 NPTTEIRL A polyoxyethylene polyoxypropylene polyarylphenol, an alkylarylsulfonate and an aromatic hydrocarbon.
The proportion of the respective ingredients in the pesticidal emulsifiable concentrate of the present invention is usually 5 to 60% by weight of pyridalyl, 2 to 15% by weight of the polyoxyethylene polyoxypropylene polyarylphenol, 2 to 15% by weight of the alkylarylsulfonate and 10 to 90% by weight of the aromatic hydrocarbon.
The pesticidal emulsifiable concentrate of the present invention may essentially consist of pyridalyl, a polyoxyethylene polyoxypropylene polyarylphenol, an alkylarylsulfonate and an aromatic hydrocarbon.
Alternatively, it may further contain other auxiliaries such as other solvents, antioxidants, preservatives, coloring adents, and the like.
Examples of the other solvent include esters such as methyl oleate and dibutyl adipate:; aliphatic hydrocarbons such as octane and decane; ketones such as cyclohexanone; and amides such as N,N-dimethyl formamide and N-~ methylpyrrolidone.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

TSP/461 (trade name of polyoxyethylene polyoxypropylene tristyrylphenol manufactured by Rhodia Nicca Co., Ltd.).
Usually, the pesticidal emulsifiable concentrate of the
» present invention contains 2 to 15% by weight of the polyoxyethylene polyoxypropylene polyarylphenol.
The alkyl group of the alkylarylsulfonate to be used in the present invention usually has 8 to 15 carbon atoms. 5 Further, examples of the salt of the alkylarylsulfonate include alkali metal salts such as sodium salt, potassium salt, etc.; and alkaline earth metal salts such as calcium salt, magnesium salt, etc.; amine salts such as aklylamine salts, alkanol amine salts, cyclohexylamine salt, etc.; and ammonium salt.
Examples of the alkylarylsulfonate to be used in the present invention include alkylbenzenesulfonate. As specific examples thereof, there are sodium dodecylbenzenesulfonate and calcium dodecylbenzenesulfonate.
The pesticidal emulsifiable concentrate of the present invention usually contains 2 to 15% by weight of the alkylarylsulfonate.
Examples of the aromatic hydrocarbon to be used in the present invention include liquid aromatic hydrocarbon solvents such as alkylbenzenes (e.g., toluene, etc.), dialylbenzenes (e.g., xylene, etc.), trialkylbenzenes (e.g., trimethylbenzene, etc.), alkylnaphthalenes (e.qg., methylnaphthalene, etc.), dialkylnaphthalenes (e.qg., dimethylnephthalene, etc.), trialkylnaphthalenes (e.qg., dimethyl-monopropylnaphthalene, etc.), phenylxylylethane,
’ oT and the like.
