Description
Technical field
The invention belongs to plant protection art, particularly relate to the agriculturally useful compositions containing dithiocyano-methane, the present composition
Can effective controlling plant diseases.
Background technology
In recent years, due to single and not Scientific Usage of Drugs, pest and disease damage has produced Drug resistance in various degree, and cause environmental pollution and
Ecological environment destroys increasingly.Along with raising and the enhancing of health perception of people's living standard, the development of environmentally friendly pesticide with
Exploitation is progressively paid close attention to by pesticide R&D worker, is to improve environment, minimizing or delaying drug resistance and the effective way of raising drug effect.
Wherein, the research and development of highly efficiency compositional agent especially contain one of the focus that agricultural antibiotic bactericidal composition is research.
Dithiocyano-methane (MBT) is that one efficiently kills algae sterilization chemicals, MBT for main bacteria present in recirculated water,
Fungus and algae (all kinds of fungus) all have efficient killing effect, and duration of efficacy is long, the pH value of adaptation and temperature model
Enclose wider.Use the consumption of 3-4ppm to heterotrophic bacteria, nitrite bacteria, sulfosalt reducing bacteria, escherichia coli, iron wire bacterium, anaerobism
The sterilizing rate of bacterium, denitrifying bacterium and sulfur bacteria is up to more than 99%, and other all kinds of bacterium also can be reached high sterilizing rate.Each removing
In class fungus, dithiocyano-methane is more preferable than the effect of its homicide/degerming medicine.Its stock solution is stable, can degrade rapidly again when application
Or decompose, environment is not resulted in secondary pollution, highly-effective low-residue.To bakanae disease of rice and Aplelenchiodes bessegi of rice, stripe disease of barley,
Net blotch, covered smut etc. have higher preventive effect.Also have kind passing a nematicide, antibacterial and other disease caused by fungus simultaneously
Well preventive effect, under recommended dose, to rice Wheat Seeds safety, and has one to be set for raising Germination Percentage of Rice and percentage establishment of seedling
With.
Cupric effective ingredient pesticide has preferable preventive and therapeutic effect to common fungoid and bacterial disease.Inventor finds, two
Thiocyanogen methane has good potentiation preventive effect with the compositions of some copper agent to fungus and antibacterial, and fungicidal spectrum is widened.At present,
The most do not find dithiocyano-methane and copper agent such as copper rosinate, copper 8-hydroxyquinolinate, tiger glue adipic acid copper, copper humate, Thiodiazole-copper,
The report of the compositions of copper sulfate, fatty acid copper, nitroacid copper, copper naphthenate, aminoacid copper, copper acetate, amine sulfonic acid copper etc..
Summary of the invention
It is an object of the invention to provide a kind of expand action spectrum, minimizing or delaying drug resistance, raising drug effect containing dithiocyano-methane
Bactericidal composition and application.
The present invention is achieved through the following technical solutions:
Bactericidal composition containing dithiocyano-methane, it is characterised in that said composition comprises A and B of effective dose, A is two sulfur cyanogen
Methylmethane, B selected from copper rosinate, copper 8-hydroxyquinolinate, tiger glue adipic acid copper, copper humate, Thiodiazole-copper, copper sulfate, fatty acid copper,
One in nitroacid copper, copper naphthenate, aminoacid copper, copper acetate, amine sulfonic acid copper, the mass fraction of A with B is than for 1:20-10:1.
Preferably, the mass fraction of A with B is than for 1:10-5:1.
The above-mentioned composition of the present invention is processed into wettable powder, water dispersible granules, water preparation, suspending agent, aqueous emulsion, microemulsion
Deng, it is 1-80% that A and B mass sum accounts for the percentage ratio of preparation gross mass.
The compositions of the present invention can prevent and treat fungus and the bacteriosis of the various plants such as vegetable, Oryza sativa L., Semen Tritici aestivi, fruit tree, preferably
Disease is bacterial wilt of tomato, bacterial leaf streak of rice and bakanae disease, Citrullus vulgaris angular leaf spot, citrus ulcer.
The compositions of the present invention compared with prior art, produces following beneficial effect:
1, purposes is widened: compositions can prevent and treat the multiple diseases of crops.
2, use cost is reduced: because compositions has raising preventive effect, preventing and treating spectrum increase, decrease Pesticide use number of times, reduce
Use cost.
3, Drug resistance is delayed: the compositions containing dithiocyano-methane and copper agent is that the component of different mechanism of action compounds, disease
It is not likely to produce Drug resistance.
4, environmental friendliness: low to people and animals and non-target organism toxicity, degraded is fast in the environment, and low-residual is free from environmental pollution.
Detailed description of the invention
