7 10% kinds of bacterium azoles oximes of embodiment bacterium ester seed treatment is handled the wheat seed test
Plant bacterium azoles 5%, oxime bacterium ester 5%, polycarboxylate 4%, sodium lignin sulfonate 3%, polyvinyl acetate 3%, gum Arabic 2%, dichlorophen 2%, alkyl benzene sulfonate calcium salt 3%, deionized water adds to 100%, mixed 10% kind of bacterium azoles oxime bacterium ester seed treatment.This proportioning is pressed 40g/100kg seed seed dressing, in closed container, seed dressing was mixed 1 minute with the seed jolting, with planting seed to the experimental field, and laggard pedestrian worker's irrigation in one day.After planting 28 days calculate preventive effect is 100%, does not observe and infects.Contrast medicament 10% kind of bacterium azoles suspension seed-coating agent and 10% oxime bacterium ester seed dressing calculated preventive effect and are respectively 88.9%, 86.5% by using with quadrat method in after planting 28 days.
The ratio of effective active composition kind bacterium azoles and oxime bacterium ester can be adjusted in 60: 1～1: 60 synergy scope in the present embodiment, plants replaceable a kind of in kind of a bacterium azoles, glyoxalin, nitrile bacterium azoles, the fluorine ring azoles of bacterium azoles, thereby forms new embodiment.
