Indoor biological activity determination
The synergism determination of the composition that embodiment 15 contains tetrachloro insect amide to beet armyworm
For trying object: beet armyworm (Spodopteraexigua), 3 instar larvaes, indoor feedingSensitive strain.
Test condition: temperature: 24～26 DEG C, humidity: RH60%, illumination: L:D=14:10
Test medication liquid making method: accurately take respectively in pesticide of the present invention with electronic analytical balanceActive component tetrachloro insect amide, Profenofos, chlopyrifos, Hostathion, former medicine is added to proper amount of acetoneAfter dissolving completely, be mixed with desired concn mother liquor with the water containing 0.1% Tween 80, by desinsection of the present inventionRatio in agent between two kinds of active components, is hybridly prepared into mixing by a certain percentage by above-mentioned mother liquor moltenLiquid, is diluted to respectively the serial liquid of tool finite concentration gradient by experimental design dosage.
Test method: adopt man-made feeds culture plate method, 24 well culture plates of selection standard cleaning, everyHole adds 1ml man-made feeds, after cooled and solidified, adds with continuous sampler to each hole of culture plate0.05ml liquid, then puts shady and cool place nature and dries in the shade. Select in the examination worm access culture plate of neat and consistent,1, every hole, every processing repeats 4 times. Examination worm after treatment is placed in observation ward to routine observation examinationWorm response situation, 72h " Invest, Then Investigate " is dead, the borer population of living.
By the Abbott formula calculation correction death rate, evaluating and adopting Bliss method, the method is to evaluate to mixOne of classical way of agent effect. Bliss thinks according to the independent joint action concept of its proposition, desinsectionTheoretical death rate P when agent is mixed can calculate with following formula:
P=Pm+Pn(1-Pm)
PmIt is the death rate (%) of the first active component target in the time that concentration is m; PnIt is the second active componentThe death rate of target (%) when working concentration is n.
If the actual of two kinds of active components target after mixing with finite concentration is greater than theoretical deadThe rate of dying P, judges that the mixing use under setting concentration of two kinds of active components has synergistic effect, otherwiseFor antagonism.
