Abstract
The invention relates to an agent for prevention and treatment of Platanus orientalis powdery mildew. The agent comprises Chinese rhubarb, common cnidium fruit, common knotgrass herb, Datura stramonium, pomegranate, Evodia rutaecarpa, Chinese prickly ash and gentrin knotweed. According to the invention, the agent is prepared through the following steps: washing and cleaning the above-mentioned components, then carrying out drying in the air, carrying out crushing into fine powder; then carrying out extraction with absolute ethyl alcohol for three times, and concentrating extracted filtrate through a rotary evaporation device until no solvent is evaporated so as to obtain the agent. When in use, the agent is diluted with clear water according to a weight ratio of 1: 200, and the diluted agent is used to spray the whole plant by an electrostatic sprayer; and the agent has the following advantages: antibacterial property of inoculation in a laboratory can reach more than 95%; in actual use, the agent can effectively prevent and treat powdery mildew; prevention rate of the agent under continuous spraying reaches 90%; in incidence of the powdery mildew, cure rate of the agent reaches more than 93%; and the agent has good efficacy and is free of residues and resistance.
Description
Technical field
The invention belongs to oriental plane tree planting technology field, the agent of especially a kind of oriental plane tree controlling powdery mildew and using method thereof.
Background technology
Oriental plane tree is deciduous tree, the height of tree can reach 30 meters, bark Dark grey, 4 ~ May of florescence, really 9 ~ October of phase, happiness illumination, happiness humid temperate climate, more cold-resistant, be applicable to growth at subacidity or neutrality, well-drained soil, blade has the effect being absorbed with poisonous gas and stagnant dust stratification dirt, and establishing in large scale survival rate is high, can effectively improve its surrounding enviroment.Oriental plane tree is the plant that a kind of disease resistance is stronger in process of growth, the incidence of disease is lower, but oriental plane tree powdery mildew has the trend increased the weight of year by year in recent years, it causes primarily of fungi, harm blade, young sprout and bud, generally in annual morbidity in 5 ~ June, initial stage face of blade or the back side produce roundlet spot and expand roughly leaf abscission gradually, bud is withered, has a strong impact on growth, very harmful.Conventional prevention and controls comprises: 1. select the disease-free and kind of resistance plantation; 2. remove the blade of morbidity, treetop and bud in time, concentrate and destroy; 3. strengthen pruning off, applying fertilizer, improve the resistance against diseases of sapling; 4. use the chemical agents such as lime sulfur, bordeaux mixture, mancozeb and triadimefon during control.Above-mentioned 1st, 2,3 belong to and process routinely, take stopgap measures and can not effect a permanent cure, and after last chemical agent uses for a long time in a large number, cause the decline of result for the treatment of, recurrence rate is high.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide and do not produce medicament residue, the agent of nonresistant a kind of oriental plane tree controlling powdery mildew.
The technical scheme that the present invention takes is:
The agent of a kind of oriental plane tree controlling powdery mildew, is characterized in that: comprise the following component by weight mixing:
And, comprise the following component by weight mixing:
Another object of the present invention is to provide the preparation method of a kind of oriental plane tree controlling powdery mildew agent, it is characterized in that: comprise the following steps:
(1) take rheum officinale, frutus cnidii, Armstrong, datura, pomegranate, evodia rutaecarpa, Chinese prickly ash and giant knotweed by metering, dry after cleaning, for subsequent use;
(2) each component is pulverized respectively, cross 80 mesh sieves, put into ethanol respectively and carry out lixiviate 36 ~ 48 hours, vibrate during lixiviate;
(3) filtration step product (2), filtrate is for subsequent use, and filter residue is put into ethanol and carried out lixiviate 36 ~ 48 hours, vibrates during lixiviate, repeats twice;
(4) the filtrate mixing of collecting three times, is evaporated to solvent-free steaming with Rotary Evaporators and namely obtains finished product under 50 degrees celsius.
And the (2) and (3) described ethanol of step is absolute ethyl alcohol.
And the (2) and (3) described oscillating condition of step is 25 degrees Celsius, 150r/min.
Advantage of the present invention and good effect are:
In the present invention, comprise rheum officinale, frutus cnidii, Armstrong, datura, pomegranate, evodia rutaecarpa, Chinese prickly ash and giant knotweed, dry after each component is cleaned, be ground into fine powder, use absolute ethyl alcohol three lixiviates again, the filtrate extracted is concentrated into solvent-free steaming through Rotary Evaporators and namely obtains finished product.During use, dilute by the weight ratio clear water of 1:200, complete stool sprinkling is carried out by electrostatic atomiser, the inoculation anti-microbial property in laboratory can reach more than 95%, energy effective prevention and therapy powdery mildew during actual use, the prevention rate sprayed continuously reaches 90%, and cure rate during morbidity reaches more than 93%, is a kind of good drug efficacy, noresidue, nonresistant medicament.
