Abstract
The present invention relates to bactericide for preventing and curing crop diseases, which is composed of concentrated filtering medium liquid of litsea cubeba foot oil and sorbitol of an emulsifying agent or Tween-80. The weight percentage of the components is 88 to 93% of the concentrated filtering medium liquid of litsea cubeba foot oil and 12 to 7% of sorbitol, or 85% of the concentrated filtering medium liquid of litsea cubeba foot oil and 15% of the Tween-80. The bactericide has a bactericidal effect which can also reach about 80% by diluting for 1000 times, has the advantages of no toxicity to people and no pollution to environments, can be used for preventing and curing diseases of various crops, which are caused by pathogenic bacteria, and can be used for preventing and curing boll shedding of cotton and fruit dropping of citrus and hot pepper.
Description
The present invention relates to a kind of prescription that is used to prevent and treat the bactericide of corps diseases forms.
The disease species of crops is various, and wherein major part is because infecting of pathogen is caused.For the control of this class disease, existing at present a lot of chemical pesticides are as tmtd, zineb, carbendazim, topsin, tpn etc.Though these chemical pesticide bactericidal effects are fair, the cost height particularly has certain toxicity, to air, soil, water quality and the agricultural product that used these chemical pesticides, certain pollution and destruction is arranged all, influences the body development of people, animal.Therefore, each state of the world today is all in that to organize the relevant expert to develop people and animals nontoxic, the crop bactericide of environmentally safe (someone is referred to as " nuisanceless ").
Purpose of the present invention just is to provide a kind of bactericidal effect good, and fungicidal spectrum is wide, and preparation cost is cheap, and nontoxic to people and animals, the crop bactericide of environmentally safe.
The crop bactericide of indication of the present invention is made up of foot oil of litsea cubeba concentrated filtrate and emulsifier sorbitol or Tween-80.
Foot oil of litsea cubeba also claims mountain grey seed waste residue oil, be industrial be that raw material production is come out of retirement and taken up an official post behind the grey seed essential oil with the grey seed in mountain (mountain grey seed seeds), residual impure thick oil.The foot oil of litsea cubeba concentrated filtrate is meant foot oil of litsea cubeba distillation concentrated, and refilters to remove resulting filtered fluid behind the impurity.
Contained emulsifier in this bactericide is if sorbierite, and then the percentage by weight of each composition is: foot oil of litsea cubeba concentrated filtrate 88-93, sorbierite 12-7.Also can add a certain amount of alkyl phenyl polyoxy ethyl ether and alkyl benzene calcium sulfonate, reduce the sorbierite of equivalent simultaneously.
Contained emulsifier in this bactericide is if Tween-80, and then the percentage by weight of each composition is: foot oil of litsea cubeba concentrated filtrate 80-85, Tween-80,20-15.
According to aforementioned proportion, each composition is mixed, fully stir, make the no oil slick in static back produce the crop bactericide that promptly obtains indication of the present invention.This bactericide can thin up.
Principle of the present invention is, in the foot oil of litsea cubeba concentrated filtrate, contain energy sterilization or antibacterial chemical substance, as (its content see Table 1) such as sesame oil alcohol, linalool, vanillin, 2-rosin spirit, camphor, citral, citrenes, also contain oil in addition, so use emulsifier with its emulsification.Because through Over emulsfication, this bactericide is sprayed at the crops surface, just can a kind of membranoid substance of very fast formation, make the germ at the ill position of plant can not spread propagation, its metabolism and grow and be subjected to the destruction of linalool, vanillic acid, α-rosin spirit etc. and cause death.External germ also is restricted and the intrusion of can not germinateing, and finally is killed.
The bactericide of indication of the present invention, bactericidal effect is suitable with the bactericidal effect of general efficient chemical pesticide such as topsin, tpn etc. now, indoor tea moire blight bacterium, tea verticillium wilt pathogen, tea zonate spot bacterium are tested, bactericidal effect is up to 97%-100%, large tracts of land is used, even dilute 1000 times, control efficiency still reaches about 80%.Its fungicidal spectrum is wide, can be used to prevent and treat tea tree red rust algae disease, verticillium wilt, moire blight, bud blight, cotton wilt, anthracnose, rice sheath blight disease, chess tangerine canker, watermelon blight, anthracnose, various crops such as pepper anthracnose by the microbial disease of cause of disease, also can be used to prevent and treat the cotton shedding of cotton bolls and citrus, capsicum shedding.Find also in the practice that it has the effect of certain expelling parasite and stimulation plant growth.
This bactericide also has two outstanding advantages, and the one, preparation cost is low, and its primary raw material is a foot oil of litsea cubeba, and foot oil of litsea cubeba is outwelled when refuse by industrial usually, and the present invention makes its changing waste into valuable, thereby raw material sources are wide, and cost is low; The 2nd, each constituent of this bactericide all is innocuous substances, and the bactericide of being prepared is nontoxic to people and animals, and environmentally safe even eaten by mistake by people and animals, does not produce harm yet.Use the agricultural product of this bactericide, do not have residual hazard.
Embodiment one:
1. get 2 tons of foot oil of litsea cubeba, distillation concentrates, and refilters and removes impurity, stays filtered fluid; 2. get 800 kilograms of the grey seed concentrated filtrates in above-mentioned mountain, add 80 kilograms of sorbierites, 10 kilograms of alkyl phenyl polyoxy ethyl ethers and 10 kilograms of alkyl benzene calcium sulfonates fully stir, and no oil slick generation is the bactericide of indication of the present invention to static back; 3. bottling; 4. when on producing, using, generally dilute 1000 times,, can suitably join rarer or denseer according to state of an illness weight.
Embodiment two:
1. get 2 tons of foot oil of litsea cubeba, inspissation contracts, and refilters and removes impurity, stays transition liquid;
2. get above-mentioned 850 kilograms of the concentrated filtrates of crossing, add 150 kilograms of Tween-80s, be stirred well to the no oil slick in static back and produce the bactericide that promptly gets indication of the present invention; 3. bottling; 4. when producing use, generally dilute 1000 times,, can suitably join rarer or denseer according to state of an illness weight.
