[0054] The dosage of the above preparations: The insecticide fertilizers selected the above eleven preparations, and the pesticides were applied according to the actual content of the effective components of each insecticide fertilizer preparation containing spinetoram and fenthion. The effective components investigated included spinetoram, fenthion and green tea components, that is, the actual composition content of the above components in each of the above preparations was calculated, and the actual mass sum of spinetoram, fenthion and green tea components was calculated. The test field was applied according to the addition amount of 12 g / mu. A blank control group and 11 treatment groups were set up in the experiment of the present invention. The preparation selected for each treatment group was repeated three times, and the repeated area was 100 square meters. 75 kg of water was added per mu for uniform spraying at the jointing stage of rice (the peak period of striped stem borer pests). The striped stem borer pest disease index of each treatment group was investigated 10 days after the application of the medicine.

[0056]

[0057] Table 2 above statistically analyzes the results of the field efficacy test of the eleven preparations after screening. According to the statistical results in Table 2, the control effects of different preparations 10 days after application are compared. By comparing Preparation 4, Preparation 5 and Preparation 6, it can be seen that when the weight ratio of ethyl spinetoram, fenthion, trace element compound fertilizer and green tea components in the insecticide fertilizer preparation is 1:6.5:12:1.5, its control effect on rice stem borer reaches 95.6%, which is significantly better than the insecticide fertilizer preparations composed of other weight ratios.
