Joint toxicity measuring in gamma cyhalothrin Rynaxypyr room
Toxicity Determination uses infusion process, using clear water as control, often handles 3 repetitions, each to repeat Conopomorpha sinensis Bradley 2
Instar larvae 50, stain ask 5s when steeping, are placed in 25 ± 1 DEG C, RH=85%, Light To Dark Ratio L:D=12:Under conditions of 12, checked after 24h
The death toll and survival number (polypide being touched with writing brush point, motionless person is death) respectively handled.United with DPS statistical analysis softwares
Meter analysis test data, the LC50 of each medicament is calculated, and the co-toxicity coefficient of mixture is calculated according to the abundant methods of Sun Yun.
Survey toxicity index (ATI)=(standard agent LC50/ reagent agent LC50) × 100；
A percentage composition+B medicament toxicity index in theoretical toxicity index (TTI)=A medicament toxicity index × mixture × mixed
B percentage composition in agent；
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100；
The criteria for classifying is acted on according to NY/T11547.7-2006 insecticide combinations：Co-toxicity coefficient (CTC) >=120 is shown as
Synergistic effect；Co-toxicity coefficient (CTC)≤80 shows as antagonism；80 ＜ co-toxicity coefficients (CTC) ＜ 120, which show as being added, to be made
With.
