Test method: use blade infusion process.Choose the green eggplant leaflet tablet close to growing point of hot-house culture, petiole sealed membrane is wrapped up, 10s is soaked in the medicinal liquid prepared, taking-up is dried in the shade naturally, putting in dactylethrae, access the golden thistle horse nymph of hot-house culture with banister bruss, often pipe connects worm 15, repeat, if clear water is processed as blank for 3 times.
Examination material after processing is placed in observation ward, the temperature of observation ward, humidity, the on-demand scalable of illumination.72 hours " Invest, Then Investigate " borer populations dead, alive.Each actual measurement mortality rate processed is calculated with Abbott formula.
Mixture effect assessment uses Bliss method, and Bliss thinks according to its independent joint action concept proposed, and theoretical mortality rate P during Mixture Use of Insecticides can calculate with following formula:
P=Pm+Pn(1-Pm)
Pm is the actual measurement mortality rate (%) of the first active component target when concentration is m；Pn is the second active component concentration actual measurement mortality rate (%) of target when being n.
If the actual of target is more than theoretical mortality rate P after mixing with finite concentration for two kinds of active components, then two kinds of active components of judgement are used in mixed way under setting concentration and have potentiation, otherwise are then antagonism.
Four chlorantraniliproles and Acetamiprid, MTI-446, Nitenpyram, flonicamid mixture, to golden thistle horse synergism determination, all show potentiation for trying each proportioning, the results are shown in Table 5.
The table 5 compositions containing four chlorantraniliproles is to golden thistle horse nymph synergism determination
