Description
Technical field
Present invention relates particularly to technical field of pesticide combination, and in particular to a kind of sterilization group containing trifloxystrobin Yu the gloomy copper of thiophene
Close object.
Background technology
Trifloxystrobin class wide-spectrum bactericide be from natural products Strobilurins as fungicide lead compound successfully
A new class of fungicides of exploitation.With efficient, wide spectrum, protection, treats, roots out, permeates, the punching of systemic activity, resistance to rainwater
The characteristics such as brush, lasting period length.To Isosorbide-5-Nitrae-demethylation enzyme inhibitor, benzamides, dicarboxyl amine and benzimidazole generate
The bacterial strain of resistance is effective, has fungicide no interactions resistance with current.To nearly all Mycophytes (Ascomycetes, Basidiomycetes,
Oomycete and Fungi Imperfecti) disease such as powdery mildew, rust, Ying's blight, net blotch, downy mildew, rice blast etc. has good work
Property.In addition to having special efficacy to powdery mildew, leaf spot, have well to rust, downy mildew, damping-off, apple apple scab, sclerotinia sclerotiorum
Activity.To crop safety, because it is capable of being fast degraded in soil, water, thus it is environmentally safe.Due to trifloxystrobin have wide spectrum,
Infiltration, the quickly performances such as distribution, crop absorb that fast, it is with upward absorbability in addition, therefore resistance of rainwater washing against performance is good, holding effect
Phase is long, therefore is considered as second generation methoxy acrylic bactericide.Trifloxystrobin is mainly used for cauline leaf process, protection activity
It is excellent, and there is certain therapeutic activity, and activity is not affected by environment.
The gloomy copper of thiophene is thiazoles organic copper fungicide, mainly prevents bacterial blight of rice, bacterial stripe, the soft corruption of Chinese cabbage
Disease and bacterial wilt of tomato.High-efficiency broad spectrum, toxicity is low, safety and environmental protection, nuisanceless, to bacterial disease special efficacy, to fungal disease
Efficiently, stablize in acid condition, it can be with other combined use of pesticides.
It is the most effective means of controlling plant diseases using chemical agent.But it applies to long-term continuous high dose single
Chemical bactericide, be easy to cause the problems such as residual of medicament, environmental pollution and drug-resistant fungi develop.Rational chemistry
Bactericide compounded or mixture have expand fungicidal spectrum, improve control effect, extend the optimum period for applying fertilizer, reduce dosage, reduce poisoning,
The positive features such as residual, the generation for delaying drug resistance of fungi and development are reduced, bactericide compounded is to solve above-mentioned ask
One of the maximally efficient method of topic.Develop new product fungicide price is constantly soaring, and in contrast, exploitation with research efficiently,
Low toxicity, the compounding of low-residual and mixture have that small investment, the lead time is short and is paid attention to both at home and abroad, and increasing one after another develops
Dynamics.We filter out pyraclostrobin and are compounded with the gloomy copper of thiophene based on the indoor screening and field trials, have bright
Aobvious synergistic effect.And it has not been reported so far about the bactericidal composition and application of trifloxystrobin and the compounding of the gloomy copper of thiophene.
