Equal-volume series concentration reagent agent, makes medicament ultimate density set concentration for test, often processes 4 times and repeat,
With clear water as blank.Cultivate 36h for 25 DEG C, check the active situation of nematicide, calculate each chemicals treatment to line
The relative lethality of worm second instar larvae.
Dead nematicide polypide is the most stiff, bending in arciform or screw type, living nematode mostly bends or twists,
During if it is determined that stiff nematicide is had any problem anyway, nematicide to be identified can be placed in 2% sodium chloride solution,
Observe again after 2min, dead stiff, movable curling or twisting (Fang Zhongda, 1998).
Mode of application judges to use co-toxicity coefficient (CTC) method.The computing formula of co-toxicity coefficient is as follows:
Actual measurement toxicity index (ATI)=(standard agent LC50/ reagent agent LC50)×100
Percentage composition+B medicament ATI × the mixture of A in theoretical toxicity index (TTI)=A medicament ATI × mixture
The percentage composition of middle B
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theory toxicity index (TTI)] × 100
When CTC≤80, then compositions shows as antagonism, as 80 ＜ CTC ＜ 120, then and compositions performance
For summation action, when CTC >=120, then compositions shows as potentiation.
