Bioassay example
The combination of active principles of different agricultural chemicals is made agricultural chemicals, is current development novel pesticide and a kind of effective and mode efficiently preventing and treating agriculturally resistant insect. After the pestsides synthesis of different varieties, usually show three kinds of type of action: summation action, synergism and antagonistic action. But it is specially which kind of effect, unpredictable, only just can know by testing in a large number. Compound synergic is well filled a prescription, and owing to significantly improving actual prevention effect, reduces the usage quantity of agricultural chemicals, thus has delayed the generation speed of pest resistance to insecticide widely, is the important means of integrated control insect pest.
Contriver is by a large amount of shaker tests, the different ratio of fluorine worm pyrrole quinoline and epoxy insect pyridine a large amount of test and effectiveness analysis have been carried out, find in certain ratio range, the insect-killing composition obtained has gain effect, and it is not only the simple addition of two kinds of medicaments, specifically it is described by following embodiment party's formula.
Adopt the mode that Toxicity Determination and insecticidal test combine in embodiments of the present invention, first Toxicity Determination is passed through, cotoxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC < 80 is anti-effect short of money, 80��CTC��120 are summation action, CTC > 120 is synergism, carries out insecticidal test on this basis again.
Test method: respectively the insect-killing composition reagent dilutions joined in above-described embodiment is become five series concentration during test, be placed in beaker respectively for subsequent use. Then the method connecing worm after first soaking leaf is adopted, take out after the blade of the same size not contacting any medicament is soaked 5s in the liquid configured, naturally dry, put into insect box, then connect for examination larva, raise under 25 DEG C of conditions, often process and repeat for 3 times, often repeating examination worm number used is 20, establishes blank simultaneously, checks dead worm number in 72h, calculate mortality ratio and corrected mortality, try to achieve virulence regression equation and calculate LC50Value. If comparison mortality ratio is greater than 10%, then it is considered as invalid test. Calculation formula is as follows:
Live before mortality ratio (%)=(worm number of living after worm number-medicine of living before medicine)/medicine worm number * 100
Corrected mortality (%)=(treatment group mortality ratio-control group mortality ratio)/(100-control group mortality ratio) * 100
To be converted into probit value (y) for examination insect corrected mortality, concentration for the treatment of (�� g/ml) converts logarithmic value to (x), draws virulence regression equation with method of least squares, and thus calculates the value of often kind of medicament. Cotoxicity coefficient CTC is calculated according to Sun Yun Liubang's formula method. Calculation formula following (taking fluorine worm pyrrole quinoline as standard medicament, its toxicity index is 100):
Actual measurement toxicity index (ATI)=(standard medicament LC50/ reagent agent LC50) �� 100
The percentage composition of B in the percentage composition+B medicament ATI �� mixture of A in theoretical toxicity index (TTI)=A medicament ATI �� mixture
Cotoxicity coefficient (CTC)=(mixture ATI/ mixture TTI) �� 100
