Embodiment Construction
[0007] Take 12% of the original drug malathion, 8% of the original drug triazophos, 8% of the 0201 type emulsifier, and 72% of the solvent xylene, put them into the reaction pot after being measured by the metering tank, and stir for 60 minutes to dissolve until uniform. Sampling analysis meets technical index of the present invention:
[0008] Malathion%(m / m) ≥12
[0009] Triazophos % (m / m) ≥8
[0010] Moisture %(m / m) ≤0.5
[0011] Acidity (in H 2 SO 4 Count)%≤0.5
[0012] Emulsion Stability Passed
[0013] Cold storage and hot storage stability Pass
[0014] Then it is pumped into the settling tank and high-level tank, and after being filtered by the filter, it becomes a packable product.
[0015] The present invention has been proved by the field efficacy test (the field efficacy test report is attached), and has the characteristics of fast knockdown, long duration and good control effect for preventing and controlling the stem borer.
