Next, a test example is shown about the emulsion stability of the agrochemical emulsion of this invention.
Test Example Hard water for testing was prepared by dissolving 3.04 g of calcium chloride and 1.39 g of magnesium chloride hexahydrate in water to make the total amount 500 ml.
95 ml of the test hard water was placed in a 100 ml stoppered graduated cylinder and left in a constant temperature water bath at 20 ° C. for a while to adjust the water temperature to 20 ° C. Next, 5 ml of the pesticidal emulsion of the present invention obtained in the above production example was added to the graduated cylinder, tilted 30 times at a rate of once every 2 seconds, and then left again in a constant temperature water bath at 20 ° C. for 1 hour. Thereafter, the state of the emulsified liquid in the graduated cylinder was observed. As for the agricultural chemical emulsions 1 to 7 of the present invention, a uniform emulsified state was maintained or the cream-like separation was 1% by volume or less.
