Abstract
The invention discloses a seed treatment agent used for preventing fungus. The seed treatment agent is characterized in containing natamycin. The seed treatment agent is prepared from natamycin, an adhesive, an anti-oxidant, a chelating agent, or water; or natamycin, other antifungal ingredients, the adhesive, the anti-oxidant, the chelating agent, and water. Seed mildew and fungal diseases can be prevented effectively via treating of seeds with the seed treatment agent, bud ratio and bud growing conditions can be improved further, and crop yield is increased. The seed treatment agent is high in efficiency, wide in pH application range, high in specificity and security, and long in antibacterial action time.
Description
Technical field
The invention belongs to biological technical field and agriculture field, provide a kind of seed treatment that contains natamycin for preventing going mouldy and the invasion and attack of fungal disease of seed.
Background technology
For agricultural production, the quality of seed quality directly affects the production of crop.And some disease funguses that seed may carry can affect germination rate and the bud gesture of seed, even cause that seed variable color rots and sprout term disease.The black-koji mould often carrying as peanut seed can cause stem rot, crown rot, and Botryodiplodia theo-bromae bacterium can cause stem rot, dry rot, and peanut tail spore bacterium can cause tail shell brown spot.The Botryodiplodia theo-bromae bacterium that corn seed may carry can cause Maize Ear Rot, stem rot, and corn top spore bacterium can cause the disease of withering slowly.Some disease funguses may be present in the seed of various plants, and the flat spore bacterium that wriggles as rotten in wheat root navel can be infected wheat, barley, corn, millet etc., can cause root rot, leaf spot, and infected seed is the important primary source of infection of leaf spot in seedling stage.Carry the seed of the pathogen of Botrytis cinerea, as sunflower, pea, broad bean, wheat, corn etc., can cause gray mold.Therefore seed is processed, killed the disease fungus that seed carries imperative.
Natamycin, claims again pimaricin, natamycin, English by name Natamycin, Pimaricin, be a kind of by streptomyces chatanoogensis (
streptomyces chatanoogensis), Natal streptomycete (
streptomyces natalensis) and brown yellow spore streptomycete (
streptomyces gilvosporeus) etc. generation bacterium produce through fermentation process, be the activated polyene macrolide antibiotics of a kind of tool.It is combined by the sterol-ergosterol on fungal cell membrane effectively, destroys the differential permeability of cell membrane, make intracellular must material seepage and cause thalline death.
The advantages such as natamycin has low dosage, high efficiency as antimycotic antibiotic, and applicable pH range is wide, and without special sense organ smell, selectivity is good, safe, and the antibacterial action time is long.Natamycin is difficult to be absorbed by human body alimentary canal, and microorganism is difficult to it to produce resistance, simultaneously because the feature such as its solvability is very low, is generally used for the surface anticorrosion of food, is unique antimycotic microbiological antiseptic can food adding in the world at present.In June nineteen eighty-two, U.S. FDA official approval natamycin can be used as food preservative.1996, Food Additives Used in China standard chemical technical committee official approval natamycin can be used as food preservative.2003, JECFA/EC also authorized by approval.FAO/WHO combination food additive Committee of Experts regulation human body can be taken in natamycin 0.3mg/kg body weight every day.Natamycin is in beverage, food, feed and pharmaceutically extensive use.But because natamycin is insoluble in water, in water, be difficult to form the suspension of stable homogeneous and easily oxidized, to reasons such as ultraviolet ray are more responsive, the application on crops produce is relatively limited to.
Summary of the invention
The object of the present invention is to provide a kind of seed treatment, use prior to seeding this seed treatment to soak, to spray and/or the mode of smearing is processed crop seed, can kill, prevent disease fungus, improve bud ratio and and bud gesture, and then increase grain yield.
The invention provides a kind of seed treatment, main active is natamycin.The composition prescription of above-mentioned seed treatment is: natamycin 5ppm---200ppm, antioxidant, adhesive, chelating agent and have or other anti-fungal compositions of nothing appropriate, all the other are water.
Use above-mentioned seed treatment provided by the invention prior to seeding to soak, to spray and/or the mode of smearing is processed crop seed, can kill, prevent disease fungus, improve bud ratio and and bud gesture, and then increase grain yield.
In seed treatment of the present invention, main active ingredient is natamycin, has the following advantages:
(1) natamycin has low dosage, high efficiency advantage as antimycotic antibiotic: natamycin is the doubly left and right of 100-200 of potassium sorbate to inhibition effect of yeast and mold, and the natamycin of 20mg/kg is equivalent to the potassium sorbate of 1000-2000mg/kg;
?(2) applicable pH value wide ranges: natamycin, compared with the preservatives such as conventional potassium sorbate, has activity within the scope of pH 4-9, can adapt to various soil environments;
?(3) natamycin selectivity is good: suppress harmful fungoid and do not act on bacterium, be applied to like this after the seed treatment such as peanut, soybean, can not have any impact to microorganisms such as useful rhizobium, be particularly suitable for fabaceous seed treatment;
?(4) safe.Natamycin is at present uniquely in the world to can be used for the antimycotic microbiological antiseptic that food adds.In June nineteen eighty-two, U.S. FDA official approval natamycin can be used as food preservative.1996, Food Additives Used in China standard chemical technical committee official approval natamycin can be used as food preservative.2003, JECFA/EC also authorized by approval.FAO/WHO combination food additive Committee of Experts regulation human body can be taken in natamycin 0.3mg/kg body weight every day.Natamycin is in beverage, food, feed and pharmaceutically extensive use.Be different from and use some agricultural chemicals to become divisional processing seed with other drug mycin, the high security of natamycin has guaranteed that it neither can cause any harm to environment, also can not have any toxic action to seed itself;
(5) the antibacterial action time is long: the stability of natamycin is high, and normal food is 2 years with the shelf-life of natamycin, adds that we have added antioxidant in seed treatment, the further stability that increases natamycin.
The present invention relates to the seed treatment that contains natamycin and there is above advantage, apply and after it is processed seed, can prevent greatly going mouldy and the invasion and attack of fungal disease of seed, and then improve the bud ratio of seed and increase final crop yield.
