Abstract
The invention discloses a plant-source bactericide for preventing and treating orchid bacterial diseases and a preparation method thereof. The bactericide is prepared from the following raw materials by weight: 20 to 30 parts of Stellera chamaejasme, 10 to 30 parts of betel nut, 20 to 40 parts of Buxus sinica root, 20 to 30 parts of Jatropha leaves, 5 to 7 parts of wormseed, 3 to 4 parts of colorful flowers, 12 to 14 parts of Amyris essence oil, 14 to 16 parts of litsea cubeba oil, 1 to 2 parts of sophocarpidine, 8 to 10 parts of pesticide emulsifier No.600, 2 to 4 parts of dialkyl carbonate, 5 to 6 parts of azone, 3 to 5 parts of sodium carboxymethylcellulose, 4 to 6 parts of aluminum magnesium silicate and 200 to 300 parts of ethyl acetate. In the plant-source bactericide provided by the invention, the used Stellera chamaejasme, betel nut, Amyris essence oil and sophocarpidine are natural active substances, are easy to degrade in the environment and have good effects on prevention and treatment of diseases lik phytophthora root rot disesase and brown rust disease, and bacteria are insusceptible to generating drug resistance to the above-mentioned substances; the added sodium carboxymethylcellulose, magnesium aluminium silicate and ethyl acetate reduce damage to the environment; and the used synergistic agents--the dialkyl carbonate and the azone and a surfactant--the pesticide emulsifier No.600 enhance bactericidal effects.
Description
Invention field
The present invention relates to a kind of bactericide, specifically relate to a kind ofly prevent and treat botanical fungicide of orchid bacteriosis and preparation method thereof.
Background technology
Orchid is Chinese tradition famous flower, only refers to the several Terrestrial orchid be distributed in Cymbidium Plants, as Chunlan, Hui Lan, sword-leaved cymbidium, Chinese cymbidium and cold blue etc., i.e. and " China blue " of indication usually.The tropical orchid of this class orchid and large flower and brilliant color differs widely, and does not have eye-catching gorgeous state, does not have very large flower, leaf, but has simple gentle and quiet, simple and elegant noble and unsullied makings, meets very much the aesthetical standard of Asians.In the cultivation history in state-owned more than 1,000 years.Chinese always regard orchid as the symbol of noble and unsullied elegance, and arranged side by side with " plum, bamboo, chrysanthemum ", are collectively referred to as " four gentleman ".But orchid often can be subject to the bacteriosises such as phytophthora root rot, anthracnose, southern blight in the process of plantation, no small loss can be brought to plantation person if dealt with improperly.Usual people use various chemical pesticide to prevent and treat these diseases.
Because chemical synthetic pesticide has, preventive effect is good, effect is fast, is one of important means of the extermination of disease and insect pest at present.But long-term a large amount of chemical synthetic pesticide of use unreasonably, the application of especially high poison, persistent pesticide, causes and causes residue of pesticide to exceed standard, environment and agricultural product contaminated, harm human and livestock health; It is serious that damage by disease and insect develops immunity to drugs, preventive effect reduces even killed natural enemies, causes damage by disease and insect rampant again, destroy the ecological balance.Botanical fungicide has low toxicity, noresidue, to the feature such as natural enemy is safer, meanwhile, its complex chemical composition of botanical pesticide, not easily develops immunity to drugs.Therefore, the research and development of botanical fungicide and application progressively obtain the attention of insider, and obtain certain development.
Summary of the invention
The object of this invention is to provide and a kind ofly prevent and treat botanical fungicide of orchid bacteriosis and preparation method thereof.
For achieving the above object, the technical solution used in the present invention is:
A kind of botanical fungicide preventing and treating orchid bacteriosis, it is characterized in that, with parts by weight, formulated by following weight raw material: root of langdu 20-30 part, betel nut 10-30 part, Chinese box root 20-40 part, leprosy leaf 20-30 part, Wormseed 5-7 part, five colours flower 3-4 part, Ah rice's amyrin oil 12-14 part, litsea cubeba oil 14-16 part, matrine 1-2 part, phenethyl phenol polyethenoxy ether 8-10 part, dialkyl carbonate 2-4 part, azone 5-6 part, sodium carboxymethylcellulose 3-5 part, Magnesiumaluminumsilicate 4-6 part, ethyl acetate 200-300 part.
Prevent and treat a preparation method for the botanical fungicide of orchid bacteriosis, it is characterized in that, comprise the following steps:
(1) by the root of langdu, betel nut, Chinese box root, leprosy leaf, Wormseed, the broken rear mixing of multicolored pollen, then adding 2-3 times of mass parts is 60-70% alcohol immersion 20-30h, filter in backward filter residue that to add 2-3 times of mass parts be again 60-70% alcohol immersion 20-30h, the supernatant of extracted twice is mixed, obtains solution A;
(2) Ah rice's amyrin oil, litsea cubeba oil, matrine are added in ethyl acetate after mixing, be stirred to and dissolve completely, and then add phenethyl phenol polyethenoxy ether, dialkyl carbonate, azone, sodium carboxymethylcellulose, Magnesiumaluminumsilicate respectively, obtain solution B after mixing;
(3) solution A obtained and solution B are mixed, be 50-80 DEG C in temperature, rotating speed is stir 30-40min in the stirred tank of 1000-2000r/min, obtains the botanical fungicide of described control orchid bacteriosis.
Beneficial effect of the present invention:
The root of langdu, betel nut, Ah rice's amyrin oil, matrine etc. that botanical fungicide of the present invention uses are natural active matter, easily degrade in the environment, have good control efficiency to the disease such as phytophthora root rot, leaf rust, and germ not easily develops immunity to drugs to it; The sodium carboxymethylcellulose added, Magnesiumaluminumsilicate and ethyl acetate, reduce the destruction to environment, and the synergist dialkyl carbonate of use, azone and surfactant phenethyl phenol polyethenoxy ether, enhance bactericidal effect.
