Comparative Production Example 1 Ten parts by weight of pyridalyl, 14.0 parts by weight of polyoxyethylene tristyrylphenol (Soprophor manufactured by Rhodia Nicca Co., Ltd.), 6.0 parts by weight of calcium dodecylbenzenesulfonate, 35.0 parts by weight of xylene and 35.0 parts by weight of N,Ndimethylformamide were mixed at room temperature to obtain a pesticidal emulsifiable concentrate (hereinafter referred to as the comparative emulsifiable concentrate 1).
Comparative Production Example 2 Ten parts by weight of pyridalyl, 14.0 parts by weight of polyoxyethylene polyoxypropylene tristyrylphenol (Soprophor BSU manufactured by Rhodia Nicca Co., Ltd.), parts by weight of calcium dodecylbenzenesulfonate, 35.0 parts by weight of xylene and 35.0 parts by weight of N,Ndimethylformamide were mixed at room temperature to obtain a pesticidal emulsifiable concentrate (hereinafter referred to as the comparative emulsifiable concentrate 2) The following Test Example illustrates emulsion stability of the pesticidal emulsifiable concentrate of the present invention.
Test Example In water, 3.04 g of potassium chloride and 1.39 g of magnesium chloride 6 hydrate were dissolved, and the solution was made up to 100 ml with water to prepare a hard water stock. One ml of the hard water stock was diluted and made up to 1,000 ml with water to prepare a test hard water having the water hardness of 34.2 ppm. Likewise, 14.6 ml of the hard water stock was diluted and made up to 1,000 ml with water to prepare a test hard water having the water hardness of 500 ppm.
Ninety five ml of the above test hard water having the water hardness of 34.2 ppm was placed in a 100 ml-measuring cylinder with a stopper and the measuring cylinder was allowed to stand in a constant temperature water bath at 0 C for a while to adjust the water temperature to 200C.
Then, 5 ml of the present invention emulsifiable concentrate obtained in the above Production Example was added to the measuring cylinder, and the measuring cylinder was repeatedly turned upside down 30 times at a rate of once per 2 seconds. After that, the measuring cylinder was allowed to stand again in a constant temperature water bath at 200C for 1 hour. When the state of the emulsion in the measuring cylinder was observed after standing, both of the present invention emulsifiable concentrates 1 and 2 maintained uniform emulsion states. When the same test was conducted by using the pesticidal emulsifiable concentrate obtained in the above Comparative Production Example, a small amount of creamy separation was observed in case of using the comparative emulsifiable concentrate 1, and a trace amount of creamy separation was observed in case of using the comparative emulsifiable concentrate 2.
When the same test was conducted by using the above test hard water having the water hardness of 500 ppm to observe the state of the emulsion, both of the present invention emulsifiable concentrates 1 and 2 maintained uniform emulsion states. However, 0.5 cc of creamy separation was observed in case of using the comparative emulsifiable concentrate 1, and a small amount of creamy separation was observed in case of using the comparative emulsifiable concentrate 2.
As described hereinabove, the pesticidal emulsifiable concentrate of the present invention is excellent in emulsion stability upon water dilution, and is useful as a pesticide.
