Embodiment
The present invention is explained further that the percentage among the embodiment all is weight percentage below in conjunction with embodiment, but the present invention is not limited thereto.
The embodiment of the invention is the method that adopts Toxicity Determination and field control effectiveness test to combine.Pass through Toxicity Determination earlier, the co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC＜80 are antagonism, and 80≤CTC≤120 are summation action, and CTC＞120 are synergistic effect, on this basis, carry out field control effectiveness test again.
Experimental scheme: adopt and to soak the method that connects worm behind the leaf earlier, the of the same size fresh blade that does not contact any medicament is soaked taking-up behind the 5s, dries naturally in the soup that configures, put into insect box; Connect then and supply examination 3 instar larvaes, under 25 ℃ of conditions, raise, every processing repeats for 3 times; Every to repeat used examination borer population be 20, establishes blank simultaneously, checks dead borer population in 72h; Calculate lethality and corrected mortality, try to achieve virulence regression equation and calculate LC
50Value.If the contrast lethality then is regarded as invalid test greater than 10%.Computing formula is following:
The insect corrected mortality is converted into probit value (y), and concentration of treatment (μ g/ml) converts logarithm value (x) to, draws virulence regression equation with method of least squares, and calculates the value of every kind of medicament thus.Calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula is (with thiophene worm amine is the standard medicament, and its toxicity index is 100) as follows:
TI * the P of the theoretical toxicity index (TTI) of M=thiophene worm amine
Thiophene worm amineTI * the P of+Acetamiprid
Acetamiprid
In the formula: M is the mixture of different proportionings
P
AcetamipridBe Acetamiprid shared ratio in composition
P
Thiophene worm amineBe thiophene worm amine shared ratio in composition
A is selected from thiophene worm amine;
B is selected from Acetamiprid.
Practice example one:
Supply the examination insect: beet armyworm.
Test medicine: Shaanxi agricultural chemicals Co., Ltd of U.S. nation provides.
Experimental scheme: effective lethal concentration scope of confirming thiophene worm amine, the former medicine of Acetamiprid and the two different proportioning mixture through preliminary experiment.
The different proportionings with Acetamiprid of table 1 thiophene worm amine are to the toxicity test of beet armyworm
Can know by table 1; Thiophene worm amine and Acetamiprid and composite to beet armyworm Toxicity Determination experiment discovery; Co-toxicity coefficient is all greater than 120 when thiophene worm amine and Acetamiprid proportioning are 80: 1 to 1: 60; Show obvious synergistic effect; Especially when thiophene worm amine and Acetamiprid proportioning during at 3: 1 to 1: 3; Synergistic effect is obviously outstanding; So when thiophene worm amine: Acetamiprid all had synergistic function between 80: 1 to 1: 60, especially when thiophene worm amine: during Acetamiprid=2: 1, the co-toxicity coefficient maximum; Synergistic effect is the most obvious; The applicant to paddy rice small brown rice planthopper, rice white-backed planthopper, brown plant-hopper, Lissorhoptrus oryzophilus Kuschel, cabbage caterpillar, diamond-back moth, various aphid, prodenia litura, thrips, cotton bollworm, cigarette beetle, pink bollworm, corn borer, pink rice borer, trialeurodes vaporariorum, Bemisia tabaci also had good synergistic effect at 80: 1～1: 60 in the scope when the weight ratio of thiophene worm amine and Acetamiprid through overtesting, and co-toxicity coefficient is all greater than 120, and it is obvious synergistic effect in 15: 1,14: 1,13: 1,12: 1,11: 1,10: 1,9: 1,8: 1,7: 1,6: 1,5: 1,4: 1,3: 1,2: 1,1: 1,1: 2,1: 3,1: 4,1: 5,1: 6,1: 7,1: 8,1: 9,1: 10 particularly to work as thiophene worm amine and Acetamiprid proportioning.
