Example Embodiment
[0016] Example 1: Indoor Toxicity Determination of the Mixture of Shalidan and Pyripoxyfen
[0017] Refer to NY / T 1154.14-2008 pesticide indoor biological activity determination method, using rice leaf dipping method for indoor synergistic biological activity determination, each treatment is repeated 4 times, each concentration treatment with 2nd instar nymphs of rice thrips 10-15 After 48 hours of treatment, check the mortality of test insects in each treatment, and calculate the corrected mortality. Use the probability value analysis method to calculate the virulence regression equation and lethal concentration LC of each drug treatment. 50 , According to Sun Yunpei's method, calculate the CTC of the drug compounding co-toxicity coefficient.
[0018] Table 1 shows the virulence test results of the mixed pair of Shachdan and pyriproxyfen on rice thrips nymphs. It can be seen from the table that the co-toxicity coefficients of the mixed agents are all greater than 100, indicating t...

[0021] Example 2: Tank mixing stability of two pesticide formulations
[0022] Table 2 The stability of two pesticides in different formulations
[0023]
[0024] It can be seen from Table 2 that the soluble powder (SP) and aqua (AS) with pyriproxyfen as the active ingredient can be mixed with water emulsion (EW) and microemulsion (ME) with pyriproxyfen as the active ingredient. And the water emulsion (EW) with the effective ingredient of Insecticide can be mixed with emulsifiable concentrate (EC), water emulsion (EW) and microemulsion (ME) with pyriproxyfen as the effective ingredient.
Example Embodiment
[0025] Example 3: Field-barrel-mixed efficacy and synergistic test of Shachongdan and pyriproxyfen
[0026] Select the group with the highest co-toxicity coefficient of Dimethophan and pyriproxyfen (mixing ratio 6:1), and then carry out the field control experiment of barrel-mixed pesticides on rice thrips in accordance with the pesticide field efficacy test guidelines of the Ministry of Agriculture ( The water consumption per mu is 45 kg). According to the number of pests before and after application in the treatment area and the control area, calculate the population reduction rate and corrective control effect.
[0027] Table 3 Field control effect of Shachongdan and pyriproxyfen (6:1) on rice thrips
[0028]
[0029] Table 3 shows the control effects of Shachongdan and pyriproxyfen on rice thrips. It can be seen from Table 3 that the control effect after barrel mixing is significant, reaching more than 85%, and the amount of active ingredients used is significantly reduced, achi...
