[0025] Preparation of the composition
[0026] The anti-termite composition provided by the invention is prepared by uniformly mixing different concentrations of hexaflumuron and activated carbon powder containing fipronil. In one embodiment of the present invention, the activated carbon powder containing fipronil is prepared by the following steps: firstly weigh the original drug of fipronil and activated carbon powder according to the ratio of 3.0% and 97.0%, and then weigh the fipronil Pour the original drug of fenproil into the pumping bottle containing analytically pure acetone (the amount of acetone depends on the volume of the weighed activated carbon powder). After the fipronil is completely dissolved, add the weighed activated carbon powder. The acetone solution should be immersed in the activated carbon powder, and after being mixed evenly, the acetone is removed under reduced pressure until the activated carbon powder is dried, thereby making activated carbon powder...
Embodiment 1
[0040]With the powder composition of the present invention: containing 40% hexaflumuron, 0.2% fipronil and 59.8% medical talcum powder, the knockdown and virus transmission tests were carried out indoors on the termites of Taiwan. The test method refers to the relevant content in the National Ministry of Agriculture's standard (NY / T1153.2-2006) "Toxic transfer of pesticides to termites", and 7.5mg of the above powder composition is evenly applied to 50 house termite workers and 5 soldiers. On the ants (treatment of spraying), the termites carrying the drug are transferred to a diameter of 9 cm and observed in a petri dish with filter paper. When 20% of the worker ants are knocked down, get 8 worker ants that are sluggish or have just been knocked down. Move into another petri dish that has 50 worker ants and 5 soldier ants that have not been sprayed with pesticides (the first transmission of poison treatment), observe regularly, and record the termite half knockdown time (Kt50)...
Embodiment 2
[0045] In the present invention, the adsorption capacity of activated carbon and several common materials with adsorption function (Table 2) on fipronil were compared. Firstly, fipronil, activated carbon powder and other adsorbent materials are formulated into a composition containing 0.2% fipronil, and the preparation method of all the compositions is the same as the preparation of activated carbon powder containing fipronil in the preparation of the composition of the present invention. Then the above-mentioned composition powder of 7.5mg was uniformly applied to the body surface of 50 house termite worker ants respectively, and half of the knockdown time Kt50 and 90% knockdown time Kt90 of the house termite were observed (the specific method was the same as in Example 1).
[0046] From the perspective of knockdown speed, the adsorption and slow-release effect of activated carbon powder on fipronil is obviously better than other kinds of adsorption materials, while the adsorp...
