Test Example Cotton aphid control test (method) Organic phosphorus agents and carbamate-resistant cotton aphids are naturally generated on cucumbers (variety: Sharp One) grown to about 180 cm. About 70 protozoa per leaf were produced in each test plant, and a predetermined amount of the above-prepared shape composition was embedded in each test plant and allowed to stand in a greenhouse at 28 ° C. The number was judged and the control effect (%) was calculated by the following formula. The results are shown in Table 1.
