Technical field
The present invention relates to technical field of pesticide, particularly relate to a kind of bactericidal composition containing metconazole with kind bacterium azoles
And application.
Background technology
Semen Tritici aestivi is the most most important frumentum raise crop, the cereal crops that Ye Shi China is important.Head blight,
Powdery mildew, banded sclerotial blight, rust and leaf blight are to threaten the important fungal disease of Wheat Production, have a strong impact on little
The yield and quality of wheat.Especially can not only be caused destructive yield by the microbial wheat scab of fusarium
Loss, and also can produce in the grain infected a large amount of deoxidation rotten Fusariumsp enol of snow (Deoxynivalenol,
And the toxin such as 6-(10-hydroxy-6-oxo-trans-1-undecenyl)-.beta.-resorcylic acid lactone (Zearalenone) DON), have a strong impact on grain security, threaten people and dynamic
The health of thing.
Wheat scab be one can by multiple Fusarium spp. or claim Fusariumsp (Fusarium spp.) cause bud-rot,
The ascomycetes disease that Seedling is withered and fringe corruption/fringe is withered.Its cause of disease includes Fusarium graminearum (F.graminearum), Asia
Continent Fusarium spp. (F.asiaticum), fusarium culmorum (F.culmorum), fusarium avenaceum (F.avenaceum),
Nearly 20 kinds such as fusarium moniliforme (F.moniliforme), Fusarium nivale (F.nivale).Big portion of China
The wheat scab of region-by-region is by Fusarium graminearum (F.graminearum) and Asia Fusarium spp. (F.
Asiaticum) mixed population causes, and wherein south Mai Qu is based on Asia Fusarium spp., and north Mai Qu is with cereal
Fusarium spp. is main.
Owing to breeding for disease resistance is limited by having immunity or high anti-genetic resources to Fusarium spp., currently used sterilization
Agent is still the important measures of effective prevention and control wheat scab.Since the sixties in last century, based on carbendazim
Benzimidazole germicide be mainly used in the chemical prevention of wheat scab, but along with service life growth and

The property of medicine, and fastness frequency is continuously increased, resistant range expands year by year, often results in wheat scab and prevents and treats unsuccessfully,
Plant disease epidemic is caused to aggravate.
Through the monitoring for resistance of nearly 30 years, find that East China is to benzimidazole sterilizations such as carbendazim
The Fusarium spp. that agent is developed immunity to drugs has formed dominant group, the benzimidazole such as conventional carbendazim, thiophanate
Antibacterial substantially loses the preventing and treating to wheat scab and is worth.Being particularly acute, fusarium graminearum produces
Drug resistance can cause the synthesis of DON toxin to dramatically increase, and has increased the weight of the harm of wheat scab and food safety
Risk.And current, it is that master prevents that wheat scab is still with carbendazim single dose or the built agent containing carbendazim
Controlling, due to the increase of drug-resistant populations, peasant, in order to reduce production loss, often doubles to use carbendazim etc. to kill
Microbial inoculum, in production, actually used dosage is often 2-3 times of preparation recommended dose, and spraying times has increased
Add, be further exacerbated by Drug resistance, pesticide residues, environmental pollution and food-safety problem.Therefore, how to have
Effect controls wheat scab, is the great social need of current Ensuring Food Safety and food safety.

It is a kind of triazole type ergosterol biosynthesis inhibitor, comprises the cis-isomer that antibacterial activity is higher
The transisomer that (1RS, 5SR) and activity are relatively low, Fusarium spp. mycelial growth is had higher by metconazole
Inhibitory activity, mainly by suppression ergosterol biosynthesis, destroys fungal cell's membrane permeability and membrane structure, by force
Strong suppression Fungal hyphal growth.But, different plant pathogenic fungi intracellular metconazole receptor Cyt.P450
Not only there is structure diversity, but also there is multiple regulation and control and physiological mechanism of flying up and down, so that different fungus performance
Different sensitivity.This antibacterial is mainly used in preventing and treating cereal crops rust (Puccinia in the world at present
Spp.), leaf blight or glume blight (Septoria spp.), net blotch (Pyrenophora teres), moire pinta
(Rhynchosporium secalis), and to powdery mildew of cereals (Erysiphe spp.) and head blight (Fusarium spp.)
The most medium prevention effect.
Planting bacterium azoles, Ipconazole, its chemical structural formula is as follows:
It is a kind of triazole type ergosterol biosynthesis inhibitor, chemical name: 2-((4-chlorobenzyl) methyl
-5-(1-isopropyl)-1-(1H-1,2,4-triazole-1-methyl) cyclopentanol, CAS:125225-28-7, have systemic activity,
Protection and therapeutic activity, can prevent and treat disease caused by ascomycetes, basidiomycetes and Fungi Imperfecti, effectively at seed
Reason root conducts to stem and leaf, and head blight, leaf spot, droop are had good preventive effect.
How metconazole and kind bacterium azoles are combined and produce for prevention and control wheat scab with rational proportioning
Efficiently threshold must be inquired into.
