In the cultivation of agricultural and horticultural crops, a number of control agents are used against pathogens and mites in crops, but their use is limited due to insufficient control efficacy or the emergence of drug-resistant pathogens and mites. In many cases, it is difficult to say that it is a satisfactory control agent because it is harmful or contaminated to plants, or is highly toxic to humans and fishes. Therefore, there is a strong demand for a drug that can be safely used with few such disadvantages.

Test Example 1. Efficacy against the spider mite On the first true leaf 7 to 10 days after the germination of the kidney bean seeded in a 2 inch pot, 30 male adults of the spider mite, the organic phosphorus resistant, were inoculated with the drug. In accordance with the formulation of the emulsion described in Example 18, the compound was diluted with water so that the compound concentration became 125 ppm and sprayed. Three days after spraying, the adults were removed, and the eggs laid during these three days were examined on day 11 to determine whether they could develop into adults, and the mite-killing effectiveness was determined. The results are shown in Table 2. The acaricidal effectiveness was determined by the following equation.
