Abstract
The invention discloses a medicament for treating rice blast. The medicament is prepared from 10 to 20 percent of albendazole, 70 to 75 percent of Chinese herbal medicament extracting solution and 5 to 30 percent of auxiliary agent, wherein the Chinese herbal medicament extracting solution is prepared by mixing Chinese herbal medicinal materials such as indigowoad root, baical skullcap root and weeping forsythia according to a mass ratio of 1:1:1 and then extracting the mixture by using 65 percent alcohol; the auxiliary agent is an emulsifying agent and a thickening agent; the emulsifying agent is 4 to 25 percent based on the total mass of all the materials; the thickening agent is 1 to 5 percent based on the total mass of all the materials; the model number of the emulsifying agent is 2201 or 4203; and the thickening agent is amylin or xanthan gum. The medicament for treating rice blast has the characteristics that: the medicinal effect is good and is better than the indoor biological test effect of the conventional medicament for treating rice blast; the bacteriostatic rate reaches 100 percent; field tests prove that the preventing effect reaches to over 90 percent; medicament resistance is difficult to generate; and the medicament cost is low. The medicament for treating the rice blast is suitable for preventing and treating rice blast.
Description
Technical field
The present invention relates to cultivation of plants, particularly, belong to the medicine that is used for paddy rice control rice blast.
Background technology
Rice blast (Rice blast) is rice blast again, burns pest, the pest of kowtowing, hangs the neck pest, is that paddy rice is subjected to cause of disease ash pears spore, and Magnaporthe grisea infects, and produces the mould layer of grey black scab in blade, stem stalk, fringe portion, even crispaturas and dead pathology.The main medicament of original control rice blast is that the Amici reaches, tricyclazole etc., and its indoor biometrics result shows that bacteriostasis rate is not high.
By retrieval, the Chinese patent application part that relates to paddy rice control rice blast is many, in recent years application has " a kind of composite dose of preventing and treating rice blast " No. 200410014349.7, number 200610048661.7 " a kind of microbiological agent resisting rice blast and its production and application ", number 200710186894.8 " a kind of bactericidal composition of preventing and treating rice blast ", number 200810051322.3 " novel environmental protection compound pesticide of control rice blast ", number 200910025838.5 " suppressing the botanical pesticide and the application aspect inhibition rice blast thereof of rice blast " etc., these patents all have its effect, but the effect of its control rice blast is still unknown.Therefore people are still at the research agricultural chemicals that control efficiency is better, curative effect is fast.
Summary of the invention
The purpose of this invention is to provide a kind of medicine for the treatment of rice blast, with faster, better treat rice blast, be agricultural production development service.
The pharmaceutical formulation of the treatment rice blast that the inventor provides is:
Albendazole 10%～20%,
Extracts of Chinese herbal medicine 70%～75%,
Auxiliary agent 5%～30%.
In the above-mentioned prescription, described albendazole is that content is 98% commercially available former medicine.
In the above-mentioned prescription, described extracts of Chinese herbal medicine is to adopt Chinese medicinal herbs Radix Isatidis, the root of large-flowered skullcap, the capsule of weeping forsythia according to 1: 1: 1 quality proportioning, mixes the extract of back with 65% alcoholic extraction, and the consumption of described 65% alcohol liquid is 15 times of medicinal material gross mass.
In the above-mentioned prescription, described auxiliary agent is emulsifier and thickener, and wherein the emulsifier consumption is 4%～25% of all material gross masses, and the thickener consumption is 1%～5% of all material gross masses; Described emulsifier model is 2201 or 4203, and thickener is dextrin or xanthans.
The drug administration process of treatment rice blast provided by the invention is to convert water spray, and the ratio that medicine is converted water is 1: 1000.
Treatment rice blast medicine characteristics of the present invention are: good drug efficacy, and than the medicament indoor biometrics better effects if of current treatment rice blast, its bacteriostasis rate reaches 100%, the field trial checking, its preventive effect reaches more than 90%, and is difficult for producing resistance, and reagent cost is lower.Be applicable to paddy rice control rice blast.
Treatment rice blast medicine of the present invention is through the plant protection unit test of Meitan County, Guizhou Province bureau of agriculture, and the control efficiency of rice blast is 80.25%～83.12%, increasing production of rice 12.56%～17.13%; The test people thinks that this medicine has diseases prevention and promotes the effect of plant strain growth, aspect rice blast prevents and treats, by supposition be used for early stage seedling leaf pest and the control efficiency of leaf pest better.
Treatment rice blast medicine of the present invention pushes away the station test through the Ba Huang township farming of Guizhou Province's Tongren City bureau of agriculture, the effect of control rice blast reaches 89%, the effect of preventing and treating banded sclerotial blight reaches 89.5%, conclusion (of pressure testing) is used to prevent and treat rice blast for this medicine and banded sclerotial blight is feasible, effect is better than other organic bactericide and biological bactericide, and have emulsifiability good, do not precipitate, not floating advantage; Converted by human drugs because of this kind again, so high-efficiency low-toxicity, free of contamination characteristics are arranged, odorless in the use to people's eye, all not stimulations of skin and respiratory system, is a kind of rising bactericide.
Guizhou mountain farming damage by disease and insect key lab conclusion in " several bactericide are to the bacteriostatic test report of Pyricularia oryzae " of providing on April 12nd, 2010 is pointed out, 5 kinds of bactericide that comprise medicine of the present invention all reach 100% to the indoor inhibitory effect of Pyricularia oryzae, and Pyricularia oryzae is had significant fungistatic effect.
Embodiment
