Description
Technical field
The invention belongs to plant protection art, it relates to a kind of fungicidal composition containing dithiocyano-methane and prochloraz, belongs to plant protection art, composition is for preventing and treating standing grain cereal, fruit tree, the fungal disease of vegetables, Micobial Disease and virus disease etc.
Background technology
In recent years, due to single and not science medication, disease and pest has produced resistance in various degree, and causes environmental pollution and ecotope increasingly to destroy. Along with the raising of people's living standard and the enhancing of health perception, the manufacture and exploit of environmentally friendly agricultural chemicals progressively receives the concern of agricultural chemicals R&D worker, is environmental protect, minimizing or delaying drug resistance and the effective way of raising drug effect.
Dithiocyano-methane (MBT) is that one efficiently kills algae sterilization chemicals, MBT has efficient killing effect for the predominantly bacteria existed in recirculated water, fungi and algae (all kinds of fungi), and duration of efficacy is long, the PH value of adaptation and wider range. Other all kinds of bacterium up to more than 99%, also can be reached high sterilizing rate by the sterilizing rate of heterotrophic bacterium, nitrite bacteria, sulphur salt reducing bacteria, intestinal bacteria, iron wire bacterium, anerobe, denitrifying bacteria and thiobacterium by the consumption of use 3-4ppm. In all kinds of fungi of removing, dithiocyano-methane is than the better effects if of its homicide/degerming medicine, its stoste is stablized, again when applying can degrade rapidly or decompose, environment can not be caused secondary pollution, highly-effective low-residue, rice bakanae disease and Aplelenchiodes bessegi of rice, stripe disease of barley, net blotch, hard smut etc. had higher anti-effect, other disease caused by kind of a biography nematode, bacterium and fungi also there is good anti-effect simultaneously, under recommended dose, to rice Wheat Seeds safety, and raising rice seed germination rate and adult seedling rate there is certain effect. Prochloraz is efficient, wide spectrum, low-toxicity sterilant, has the multiple actions such as prevention & protection treatment, works by suppressing the biosynthesizing of sterol, and without systemic action, the anti-effect of multiple diseases caused for ascomycetes and imperfect fungi is extremely good. Conventional use the water prevention Bakanae disease of rice, rice blast, the anthrax of gourd, fruit and vegetable, leaf spot etc.
For improving the prevention effect of medicament, it is necessary to carry out rational composition research. Also do not report about the two-element active component composition containing dithiocyano-methane and prochloraz at present.
Summary of the invention
It is an object of the invention to provide the composition of the two-element active composition of a kind of dithiocyano-methane and prochloraz, it is undertaken composite by the sterilization component of two kinds of different structures, the different mechanism of action, expanding prevention spectrum and raising drug effect. Another object of the present invention is to provide a kind of containing the purposes of dithiocyano-methane and the composition of the binary bioactive ingredients of prochloraz.
It is an object of the invention to be realized by following measure:
A kind of containing the composition of dithiocyano-methane and prochloraz, it is characterized in that the activeconstituents of composition is binary composition dithiocyano-methane and prochloraz or prochloraz salt, the ratio of weight and number of dithiocyano-methane and prochloraz or prochloraz salt is 1:20-20:1, preferably, ratio of weight and number is 1:15-10:1.
Prochloraz salt in the above-mentioned composition of the present invention is the one in prochloraz-manganese chloride complex, prochloraz nantokite, prochloraz zinc salt etc.
In above-mentioned composition, it is 1-90% that the quality summation of two-element active composition accounts for the per-cent of composition total mass, it is preferable that, per-cent is 2-60%.
The above-mentioned composition of the present invention can be made into the preparations such as aqueous emulsion, suspension agent, water dispersible granules, wettable powder, microemulsion, and described preparation is obtained by the conventional technology of preparing of this area.
Present invention also offers the purposes of above-mentioned composition for controlling plant diseases, wherein said plant is standing grain cereal, fruit tree or vegetables, disease is the fungal disease of plant, Micobial Disease, virus disease, such as rice bakanae disease, Aplelenchiodes bessegi of rice, wheat smut, oranges and tangerines anthrax etc.
The invention has the beneficial effects as follows:
1, synergism is obvious: test shows, the composition containing dithiocyano-methane and the two-element active composition of prochloraz is obvious to disease synergy;
2, use cost is reduced: because of composite, there is the anti-effect of raising, decrease use number of times, reduce use cost;
3, delay resistance: the composition of two kinds of different mechanism of action is composite, and pathogenic bacteria not easily develops immunity to drugs, delay pathogen to the generation of single dose resistance.
Embodiment
Following example of formulations and biological Examples are the further explanations to the present invention, but the present invention is not confined to proportioning and the controlling object of this embodiment.

Finding in addition, the sickness rate of the aphelenchoides besseyi of compositions-treated is lower.
Embodiment 9 composition is to wheat smut field test
Having carried out wheat smut field test with composition, and established corresponding single dose and blank, community 20m established by every medicament2. Wheat seed is dressed seed by with medicament, and in wheat breast ripe phase or ripening stage, every community adopts diagonal lines 5 sampling, gets 0.5m at often2Investigate total strain number and smut strain number, calculate diseased plant rate.
The anti-effect of x to be working concentration be active component A during a, the anti-effect of y to be working concentration be active ingredient B during b. Relatively theoretical effect and actual effect, evaluates the synergy of composition, as synergism when being greater than theoretical anti-effect taking the anti-effect of reality. Composition to the prevention effect of wheat smut in table 2.
Table 2 composition is to wheat smut field efficacy
By composition to wheat smut test find, the two-element active composition of dithiocyano-methane and prochloraz when proportioning is 1:9-5:1, composition to the effect of wheat smut all higher than the theoretical anti-effect of composition.It is evident that wheat smut is synergy by the composition of dithiocyano-methane and prochloraz.
Embodiment 10 composition is to oranges and tangerines anthrax field test
According to scheme, prepare composite dose and single dose, and carry out active pre-experiment. According to determination of activity trial test, Formulation is become the concentration needed. Before test, community is set, lists, and establish corresponding single dose and blank, adopt the conventional conventional spray of manual sprayer. After 1st spraying, 7-10d sprays 1 time again, the oranges and tangerines anthrax disease situation that after the 2nd dispenser, 10-14d investigation is listed and processed. Use Abbot formula, percentage is converted to anti-effect.
In theoretical effect, x is concentration is the effect of substance A during a, and y is concentration is the effect of substance B during b, compares theoretical effect and actual effect, evaluates the synergy of composition, as synergism when being greater than theoretical anti-effect taking the anti-effect of reality. The prevention effect of oranges and tangerines anthrax be the results are shown in Table 3 by composition.
Table 3 composition is to oranges and tangerines anthrax field efficacy
By composition, the test of oranges and tangerines anthrax is found, at the two-element active composition of dithiocyano-methane and prochloraz-manganese chloride complex when proportioning is 1:1.5 and 1:6, composition to the effect of oranges and tangerines anthrax all higher than the theoretical anti-effect of composition. It is evident that oranges and tangerines anthrax is synergy by the composition of dithiocyano-methane and prochloraz-manganese chloride complex.
