Description
Technical field
The invention belongs to proportion of crop planting technical field, and in particular to a kind of prevention and controls of rice blast.
Background technology
Rice is cereal crops important in the world, and cultivated area is only second to wheat and corn.Rice yield occupies the world
More than the 1/4 of total output of grain, occupy yield of grain in China more than half.Rice blast (Rice Blast) is main in the world
One of rice disease, be (asexual by sac fungus Magnaporthe oryzae (T.T.Hebert) Yaegashi＆Udagawa
State：Pyricularia oryzae) caused by it is a kind of it is sudden it is strong, be easy to one of popular important disease of rice, be worldwide
Fungal disease.The disease can be damaged to rice throughout the year, and it is endangered throughout each position of rice, there is seedling rice blast, leaf
Pest, pulvinus pest, section rice blast, panicle blast, branch stalk pest and grain pest etc..Rice blast is widely distributed, and there are generation in global 85 countries,
And one of rice disease of most serious is endangered in China South And North Rice Regions.Rice blast causes 10~30% rice to produce every year in the whole world
Amount loss, annual production loss can support the population of the whole world 6,000 ten thousand.Preventing and treating to Pyricularia oryzae at present mainly uses anti-pest
Kind and chemical agent, easily degenerated because physiological races of rice blast fungus is also easy to produce variation, disease-resistant variety, and long-term chemical preventing and treating
The caused resistance to the action of a drug, ecological environment is caused seriously to pollute in addition, agricultural product toxic chemical substance residual quantity directly threatens the world to eat
Product safety.Therefore, it is significant that effectively preventing means are explored.
The content of the invention
The invention is intended to propose a kind of prevention and controls of rice blast, go to treat and prevent rice using rice blast preventing and treating composition
Seasonal febrile diseases, to solve the problems, such as to threaten food security using chemical prevention product residual poisonous to ecological environment and agricultural product.
The solution of the present invention is：A kind of prevention and controls of rice blast, it is applied to rice using rice blast preventing and treating composition and makees
On thing, the raw material of the rice blast preventing and treating composition includes summer and autumn tea fresh leaves and wide yulan, and the parts by weight of each raw material are
20~30 parts of summer and autumn tea fresh leaves and wide 30~50 parts of yulan.
The working principle and beneficial effect of the present invention：Main component in summer and autumn tea fresh leaves is Tea Polyphenols, tea polyphenol extract
Technique is simple, and production cost is low, and has no side effect to human body, environment, and it suppresses the mechanism of action of microorganism and is total to by many factors
Same-action, most important characteristic are conjugated protein matter.Existing numerous studies show, Tea Polyphenols to pathogenetic bacteria especially to medical science and
Food malignant bacteria has stronger inhibitory action.And Tea Polyphenols the inhibitory action of disease fungus is focused primarily upon dermatophyte,
Reproductive system fungi, it is also less to the inhibitory action report of plant epiphyte, therefore using Tea Polyphenols as a kind of green plants source disease
Opportunistic pathogen protective agents, there is great potentiality to be exploited.Wide yulan is derived from wide yulan and trims or come off naturally discarded and profit
The branch, stem, leaf, flower, fruit or its mixture, southern magnolia and the Hua Zhonghan that discard is processed during other products with the plant production
There are a variety of chemical compositions such as volatile oil, magnoflorine, flavonoids, phenols and sesquiterpene lactone.Pharmacological testing show to normal or
Animal under narcosis has slow antihypertensive effect.Research shows that the sesquiterpene terpene in wide yulan petal can cause hat
Shape arteries is expanded, and young fruit extract has boosting, and wide yulan plant volatile is to staphylococcus aureus and large intestine
Bacillus has bacteriostatic activity, and the flavonoids and phenolic compound in wide magnolia extract also have stronger antioxidation activity.Fan Zheng
Ball etc. extracts 48 kinds of volatile compounds using MAE-HS-SPME methods from southern magnolia piece.But wide yulan is applied to
The research of disinfectant use in agriculture is seldom, therefore, scientist has carried out the Primary Study of correlation, is carried by the ethanol for determining southern magnolia
Thing and each extraction part is taken to find the agricultural actives in southern magnolia to the bacteriostatic activity of plant pathogenic fungi, be it
Comprehensive development and utilization provides scientific basis, and the botanical pesticide bactericide to research and develop new lays the foundation.The present invention pass through by
Summer and autumn tea fresh leaves and wide yulan compounding, the coarse bitter taste of the summer and autumn tea fresh leaves food value of leaf is heavier, therefore is unfavorable for tea making, therefore the present invention
Tea Polyphenols is extracted from it, is existed using beneficiating ingredient phenols therebetween and Flavonoid substances coordinated, collective effect
On the spore of sac fungus, mixture it is active extremely strong, can not only inactivate sac fungus dehydration, while the numerous of spore can also be prevented
To grow, fungistatic effect is especially optimal to the fungistatic effect of sac fungus, and the preventive and therapeutic action of rice blast is controlled close to complete,
The prescription of the present invention is natural plant extract simultaneously, has the advantages that noresidue, will not develop immunity to drugs, is advantageous to overcome
The problem of chemical agent Environmental Residues and rice blast cause of disease develop immunity to drugs.
One of it is preferred that, the parts by weight of each raw material are 20 parts of summer and autumn tea fresh leaves and wide 30 parts of yulan.
It is preferred that two, the parts by weight of each raw material are 30 parts of summer and autumn tea fresh leaves and wide 50 parts of yulan.
Under the proportioning, therapeutic effect can reach more than 90% for summer and autumn tea fresh leaves and wide yulan.
The preparation method of rice blast preventing and treating composition comprises the following steps：
The first step：Prepare summer and autumn tea fresh leaves and wide yulan in proportion, after raw material is destroyed into tissue, be put into extraction kettle, add
Enter the organic solvent of 2~3 times of raw material weights, extract respectively, 12~24h of soak extraction under room temperature condition, extract 2~3 times, obtain tea
Polyphenol extract solution and wide yulan extract solution, mixed extract is obtained after mixing；
Second step：0.02~0.05 times of heavy emulsifying agent of mixed extract is incorporated as to mixed extract, is sufficiently stirred, then
25~100 times of heavy water of mixed extract are incorporated as, the aqueous emulsion of rice blast preventing and treating composition is made after mixing.
Beneficial effect：By summer and autumn tea fresh leaves and the organic extraction of wide yulan, obtaining mixed extract, adding emulsifying agent
Aqueous emulsion is configured to water, the administration suitable for rice blast preventing and treating composition.
Further, the emulsifying agent is NPE.NPE is called NP-10, right and wrong from
Sub- surfactant, w/o type emulsifying agent or O/W types emulsifying agent, dispersant are widely used as, is synthetic detergent primary raw material, is
One of main additive of botanical pesticide, it is free from environmental pollution, residues of pesticides will not be caused.
Further, the organic solvent is ethanol.Ethanol is volatile, can directly be volatilized in air after a period of time after extraction
In, the use of agricultural chemicals is not interfered with, will not cause medicament residue yet.
