Abstract
The invention discloses a bactericidal disease prevention mixture containing algal polysaccharide and azoxystrobin. The bactericidal disease prevention mixture comprises 1-65% of algal polysaccharide, 5-40% of the azoxystrobin and 5-20% of an agricultural auxiliary agent. After the bactericidal disease prevention mixture is used, the problem that drug resistance is generated after the single azoxystrobin is used for a long time can be solved; the bactericidal disease prevention mixture has the effects of sterilizing, eliminating diseases and improving the disease resistance of plants, and is low in cost, and convenient to manufacture and is worthy of popularization.
Description
Technical field
The present invention relates to technical field of pesticide, particularly relate to a kind of sterilizing disease-preventing mixture containing algal polysaccharides and Fluoxastrobin.
Background technology
In the production of crops and horticultural crop, crop often run in process of production multiple fungi or infecting of bacterium and various disease, also normal because of in soil multiple cause a disease or saprophytic fungus and bacterium infect harm, cause rotten kind, rotten, dead seedling.In order to prevent crop from falling ill, often need to apply diseases prevention medicine to improve the resistance against diseases of crop to crop, but existing diseases prevention medicine mostly cost is higher, effect is not good yet, and in addition, Fluoxastrobin is a kind of common antibacterial agent, but due to long-term a large amount of use, create resistance, poor effect.
Summary of the invention
The present invention, in order to solve the above-mentioned deficiency of prior art, proposes a kind of sterilizing disease-preventing mixture containing algal polysaccharides and Fluoxastrobin.
In order to solve the problems of the technologies described above, the present invention by the following technical solutions: a kind of sterilizing disease-preventing mixture containing algal polysaccharides and Fluoxastrobin, comprises each component of following weight percentage:
Algal polysaccharides 1%-65%;
Fluoxastrobin 5%-40%;
Agricultural agent 5%-20%;
Water surplus.
Fluoxastrobin is a kind of protection, treatment, permeate, root out the wide-spectrum bactericide of mechanism.The mechanism of effect suppresses mitochondrial respiration by entering in germ, thus destroy the energy synthesis of germ.Therefore, the spore germination of germ and the process of mycelial growth are suppressed.But, due to a large amount of uses of Fluoxastrobin, cause germ resistance problem in various degree.
Algal polysaccharides has antibacterial and anti-virus ability.In patent CN103655225A " a kind of moisturizing bath gels containing algal polysaccharides ", utilize algal polysaccharides as antimicrobial component.Zhang Ying etc. find that in 2006 " viral journal " the 4th phase " the antiviral activity Primary Study of the seven kinds of algal polysaccharides in the South Sea " algal polysaccharides has antiviral ability.Han Lijun etc., at 2000 " Marine Sciences " the 24th volume, find in o. 11th " marine algae extract is on the impact of vegetable seeds rudiment " that marine algae extract can improve rudiment and the growth of seed significantly.Wang Song etc. are at 2003 " Marine Sciences " the 27th volume, and 3 phases " oligosaccharides inducing plant defense repercussion study progress " middle finger goes out algal polysaccharides effectively can produce defence immune response by inducing plant.
Algal polysaccharides refers to the polysaccharide extracted from the algae of ocean.The algae of ocean comprises sea-tangle, marine alga, brown alga, red algae, chlamydomonas, green alga etc.Algal polysaccharides, as a kind of polysaccharide material of natural extraction, has very strong antibacterial, antiviral, oxidation resistant effect.And can effectively produce disease-resistant by inducing plant, the effect of degeneration-resistant environment.The material of polysaccharose effectively can form layer protecting film at plant surface simultaneously.Carbohydrate contained by marine alga mainly polysaccharose, accounts for more than 50% of algae dry matter.So the wide material sources of algal polysaccharides, be cheaply easy to get.
By used in combination to both Fluoxastrobin and algal polysaccharides, can synergistic effect be played, the resistance problem of Fluoxastrobin can also be solved simultaneously.
Preferably, described algal polysaccharides is selected from sea-tangle, brown alga, red algae, blue-green algae, chlamydomonas, one or more in green alga.
Preferably, described agricultural agent contains dispersant, emulsifier, thickener, defoamer and antifreezing agent.Wherein, dispersant as nekal, polyvinylpyrrolidone, dioctyl sodium sulfosuccinate etc.; Emulsifier as alkylphenol polyoxyethylene, alkyl glycoside etc.; Thickener as aluminium-magnesium silicate, bentonite, gum Arabic etc.; Defoamer as ester-ether type compound, fatty alcohol etc.; Antifreezing agent as propane diols, glycerine, urea etc.
Compared with prior art, the present invention, by used in combination to both Fluoxastrobin and algal polysaccharides, can play synergistic effect, improves the resistance against diseases of plant, can also solve the resistance problem of Fluoxastrobin simultaneously, and with low cost, easy to make, is worthy to be popularized.
