Abstract
The invention provides a composition for controlling phoma stem canker of rape, belonging to the field of pesticides. The composition for controlling phoma stem canker of rape comprises active ingredients of 10-50 percent by mass of carbendazim and 1-20 percent by mass of tebuconazole. The active ingredients of the composition provided by the invention comprise carbendazim and tebuconazole, and thus the composition is excellent in controlling effect for the phoma stem canker of rape. Contrast tests indicate that the controlling effect of the composition provided by the invention is greater than the sum of controlling effects of the carbendazim and the tebuconazole which are respectively applied for the phoma stem canker of rape, which shows that the carbendazim and the tebuconazole in the composition provided by the invention have a remarkable synergistic effect on controlling the phoma stem canker of rape. In addition, the phoma stem canker of rape is controlled by adopting the composition provided by the invention, under the condition of ensuring the controlling effect, the consumption of the carbendazim and the tebuconazole is reduced, and thus the potential pesticide resistance risk of leptosphaeria maculans to the carbendazim and the tebuconazole is lowered.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of composition preventing and treating real-time fluorescent RCR canker.
Background technology
Carbendazim chemistry N-(2-benzimidazole base)-methyl carbamate by name is a kind of benzimidazole germicide, and main antimicrobial mechanism is the mitosis process by suppressing thalline, finally causes germ dead.Carbendazim has good preventive effect to the crop pest that multiple sac fungi, basidiomycetes, imperfect fungus cause, and is widely used in the disease control in multiple kinds of crops and fruit vegetables storing.
Tebuconazole is a kind of pathogen ergosterol biosynthesis inhibitor, acts on the interruption of ergosterol synthesis in phytopathogen thalline, and then shows as strong bacteriostasis.This medicament disinfecting spectrum is wide, the lasting period long, have excellent bacteriostatic activity to the fungi of sac fungi, imperfect fungus and Basidiomycetes, goes out excellent prevention, treatment and eradicant action at variable rate technology; To crop and Environmental security.
Rape is the main oil plants of China.The stem foot canker caused by Leptosphaeria maculans is the bottleneck factor of Rape-seed production, is the one of the main reasons causing production loss in world wide.This pathogen asexual generation is Phoma (Phoma lingam), has pathogenic by force to rape; Extensively be present in multiple rape producing regions such as Australia, Europe and North America; List China's disease quarantine object in.Only there is weak pathogenic L.biglobosa in China, its asexual generation is also Phoma P.lingam, threatens less to the production of rape.But, in recent years, along with China's imported oil vegetable seed quantity expands year by year, the spread risk that the rape seed of being scattered around Gang Qu, oil plant causes real-time fluorescent RCR canker potential, therefore, research and develop for this quarantine disease prevention and control medicament, set up the safety in production of China rape " fire wall " significant.
Summary of the invention
The object of this invention is to provide a kind of composition preventing and treating real-time fluorescent RCR canker, its active component carbendazim and Tebuconazole, to control real-time fluorescent RCR canker, there is synergistic effect.
Object of the present invention adopts following technical scheme to realize.
Prevent and treat a composition for real-time fluorescent RCR canker, active component is carbendazim and Tebuconazole, and the mass percentage of carbendazim is 10-50%, and the mass percentage of Tebuconazole is 1-20%.
The mass percentage of described Tebuconazole is 10-20%.
The mass ratio of carbendazim and Tebuconazole is (0.1 ~ 10): 1.
Described composition is wetting powder, suspending agent or aqueous emulsion.
The active component of the present composition is carbendazim and Tebuconazole, excellent to real-time fluorescent RCR canker preventive effect.Comparative trial shows: the preventive effect of the present composition to real-time fluorescent RCR canker is greater than carbendazim and Tebuconazole acts on preventive effect sum respectively, illustrates that in the present composition, carbendazim and Tebuconazole have obvious synergistic function in control real-time fluorescent RCR canker.In addition, adopting present composition control real-time fluorescent RCR canker, when ensureing preventive effect, decreasing the consumption of carbendazim and Tebuconazole, thus reduce the potential resistance risk of real-time fluorescent RCR ulcer bacteria to carbendazim and Tebuconazole.
