Test subjects: cyperus bigelovii, ovum.
Reagent to be tested: dissolving fenoxycarb, indoxacarb, metaflumizone and spinetoram active compounds in absolute ethyl alcohol respectively, and diluting with water to prepare the required mother liquor.
The test method comprises the following steps: preparing the mother liquor into a series of concentrations by adopting an immersion method; transferring the eggs to a beaker with liquid medicine, treating the eggs with the liquid medicine, and transferring the eggs to a normal condition for culture; repeating for 3 times, and setting clear water control, wherein each cup contains 20 eggs; and (5) surveying and recording the number of hatched eggs and the number of dead eggs, and calculating the egg death rate.
The evaluation method comprises the following steps: the method is one of the classical methods for evaluating the effect of the mixture by adopting a Colby formula. The Colby formula is as follows: e ═ X + Y- (X × Y)/100.
Wherein X is the mortality in m ppm of active compound A, expressed as a percentage of the untreated control; y is the mortality rate at an application rate of n ppm of active compound B, expressed as a percentage of the untreated control, and E is the mortality rate at an application rate of m + n ppm of active compounds A and B, expressed as a percentage of the untreated control.
If the actual mortality rate of the target after the two active ingredients are mixed at a certain concentration is greater than the theoretical mortality rate E, the two active ingredients are judged to have synergistic effect when being mixed at a set concentration, otherwise, the two active ingredients are antagonistic.
And (3) test results: referring to Table 2, fenoxycarb and indoxacarb/flumizone/spinetoram combinations have synergistic effects on eggs of Trichoplusia.
