(54: 6) 60% Imidacloprid Biphenthrin water dispersible granules that the above-mentioned co-toxicity coefficient that screens is higher is diluted to the soup that contains effective composition 250,500,1000, four concentration of 2000ppm with deionized water, get the pine piece of 1.2*2.2*7.8cm, with No. 1 sand paper that surface finish is smooth, in above-mentioned soup, be dipped to wooden unit drenched fully till (contrast is soaked with clear water) and natural seasoning.The amount of trying to please 250ml vial, No. 5 vermiculites of the water content of packing into therein 200% are to a half volume of vial, in the vertical vermiculite that inserts vial of half of the above-mentioned pine piece of having handled, half stays the vermiculite surface, put into Taiwan formosanes (Coptotermes formosanus Shiraki) 5 grams again, cover glass cap.Each concentration is established 3 repetitions, establishes 3 of blanks simultaneously.Total Test places the import Hitachi board climatic cabinate of 27 ℃ of temperature, relative moisture 85%, and in 4 weeks of experimental period, the routine observation termite is got food pine piece and death condition in experimental period.Timber moth corrosion test the results are shown in Table 3:
Table 3 adopts (54: 6) 60% Imidacloprid Biphenthrin water dispersible granules to handle the timber gulf formosanes worker ant moth corrosion test of combating typhoon:
Table 3 explanation: intact value 100: the test block surface does not have moth erosion vestige;
Intact value 90: there are slight moth erosion vestige, the degree of depth≤0.2mm in the test block surface;
Intact value 70: the moderate moth erosion in test block surface, the degree of depth≤1/3;
Intact value 40: the serious moth erosion in test block surface, the degree of depth 〉=1/2, but moth is not disconnected;
Intact value 0: test block table moth is disconnected.
Table 3 shows, uses the effectively moth erosion of termite-proof of timber of the soup processing of (54: 6) 60% Imidacloprid Biphenthrin water dispersible granules active ingredient 500,1000,2000ppm.Promptly 500,1000, the timber handled of the soup of 2000ppm concentration, average intact value 100 of test block and termite average mortality 100%.
The insecticides that is used for termite control of the present invention is to the soil treatment penetration test:
(54: 6) 60% Imidacloprid Biphenthrin water dispersible granules is diluted to the soup that contains effective composition 500,1000, three concentration of 2000ppm with deionized water.Cross 20 order stainless steel mesh adopt the fresh sandy loam of returning from the field, the glass tube that is loaded on long 15cm, diameter 3cm then interrupts, loading height 5cm, and pour 2% agar 7ml liquid at an end (A end) of glass tube, after treating that agar solidifies, add above-mentioned soup at the other end (B end) by 4 liters every square metre dosage, allow solvent evaporates after 4 hour, also pour 2% agar 7ml liquid at the B end.Place with 1 of water-moistened 1.5*1.5*1.5cm pine piece at the A end, the B end is put into termite 1.0g, with the glass tube sealing two ends, and place the import Hitachi board climatic cabinate of 27 ℃ of temperature, relative moisture 85%, routine observation termite breakthrough process soil and death condition with 60 order stainless (steel) wires.This is tested each concentration and establishes 3 repetitions, establishes 3 of blanks simultaneously.
Soil treatment penetration test result:
But soil is handled in Taiwan formosanes partial penetration, and termite is because of the contact medicament, and is dead in 2～7 days respectively.The soil of the above concentration chemicals treatment of 1000ppm has very strong toxicity to the Taiwan formosanes, and in duration of test, the Taiwan formosanes does not enter the soil of chemicals treatment, the results are shown in Table 4.
Table 4 Taiwan formosanes is to adopting the soil penetration capacity of (54: 6) 60% Imidacloprid Biphenthrin water dispersible granules
From above-mentioned every test as can be seen: the water dispersible granules that is mixed of (54: 6) 60% Imidacloprid Biphenthrin water dispersible granules has the stronger power of knocking down and the power of causing death to Taiwan formosanes (Coptotermes formosanus Shiraki), this water dispersible granules valid density is higher, extension rate can reach 600 times during use, the influence of solvent load and solvent be can obviously reduce, timber, the processing of soil control termites are suitable for environment.
