Spirotetramat is a novel ketonic acid insecticide and acaricide that kills pests by inhibiting lipid synthesis. The pesticide is suitable for controlling sucking mouthparts pests such as whitefly, aphid, thrips and scale insects, and has the functions of high efficiency and two-way conduction. kaiping aida sanitary ware technology co.,ltd , https://www.kpfaucets.com
In order to clarify its control effect on Bemisia tabaci, experts conducted a drug efficacy test in the greenhouse mini pumpkin field:
The test data showed that 24% spirotetraethyl ester suspension had better control effect against Bemisia tabaci, and the pharmacodynamic performance was different from that of the control agent 40% acetamiprid water-dispersible granules. 3 days after the drug, the control effect of 24% spirotetral ethyl ester suspension 2000 times solution was 63.48%, the control effect reached 82.37% after 7 days, and the best prevention of 40% acetamiprid water dispersible granule 3000 times solution. The effect was 78.83%, which appeared 3 days after the drug, indicating that the 24% spirotetraethyl ester suspension was slightly less effective. After 14 days of drug administration, the control effects of 24% spirotetral ethyl ester suspension 2500 times solution and 2000 times solution were 41.55% and 47.24%, respectively. The 40% acetamiprid water-dispersing granules 3000 times liquid has no effect. 28 days after the drug, the control effect of 24% spirotetral ethyl ester suspension 2000 times solution was still as high as 44.41%, and the effect was significantly better than 40% acetamiprid dispersing granules.
The pesticide network found that the 24% spirotetraethyl ester suspending agent was slightly less effective than the 40% acetamiprid water dispersible granule. However, it has a long-lasting effect and can be used for the control of Bemisia tabaci in production. When the density of adults of Bemisia tabaci is large, it can be mixed with acetamiprid to combine the quick-acting and sustained effects of the two.
