Description
Technical field
The present invention relates to biological pesticide technical field, be specifically related to a kind of botanical fungicide and application thereof.This bactericide is mainly used in the control of the important plant diseases such as powdery mildew, epidemic disease and gray mold, can be widely used in nuisanceless and organic farming production.
Background technology
Agricultural chemicals is to ensure agricultural production and the indispensable important means of production of grain security, but since the sixties in last century, the long-term use of a large amount of chemical pesticides has caused serious negative effect to environment and human and livestock health.Although country pays much attention to the security management work of agricultural chemicals in recent years, successively prohibit, limited the use of tens kinds of high poison, persistent pesticide, but because the exceed standard pollution of dining table that causes and the poisoning of initiation of residue of pesticide still happens occasionally, the development of people's health and agricultural has been caused harmful effect.The agricultural product quality and safety management has become the important component part of state food safety management, is the emphasis of current attention from government, the focus of social concerns.Simultaneously, the pesticide quality safety problem also is the key factor that affects China's present stage Agricultural Competitive.China is as WTO member state and export of farm produce big country, recent years since persticide residue exceed standard, with the trade dispute of the states such as Europe, the U.S. and Japan continuous, greatly affected the export trade of agricultural product, food.
Population is growing, arable area reduces increasingly, although transgenic technology and Resistant breeding technique can alleviate the generation of disease pest and weed to a certain extent, but still can not replace the critical positions of agricultural chemicals.Therefore, for Guarantee Grain Production safety, must use agricultural chemicals to carry out " insect population is taken grain by force ".Simultaneously, in order to ensure the safety that agricultural chemicals uses, also must vigorously promote the use environmentally safe, to the biopesticide of people and animals' low toxicity.As the important member of biopesticide, although the botanical pesticide applicating history is long, because the past is low to the availability of botanical pesticide active ingredient, usually, effect slow because of effect is unstable can't use by spread.Therefore, be badly in need of better, the stay-in-grade pollution-free plant source pesticide product of some action effects of exploitation in the production.
Jamaicin (Berberine) claim again berberine, is a kind of common morphinane alkaloid, molecular formula C
20H
18NO
4It is present in many plants of ten genus of four sections such as Berberidaceae, such as the coptis, giant knotweed etc.Jamaicin is pharmaceutically of many uses, has a broad antifungal spectrum, external to multiple Grain-positive and the equal tool bacteriostasis of negative bacterium, wherein hemolytic streptococcus gold Portugal bacterium, comma bacillus, meningococcus, shigella, typhoid bacillus, diphtheria bacillus etc. there is stronger inhibitory action, antibacterial during low concentration, sterilization during high concentration.In addition, infected by influenza, Amoeba, Leptospira, some dermatophyte also have certain inhibitory action.But medical research is indicated shigella dysenteriae, hemolytic streptococcus, golden Portugal bacterium etc. and very easily jamaicin is produced drug resistance.Have at present in addition 0.5% jamaicin aqua is used for the diseases such as tomato gray mould, cucumber white powder, capsicum epidemic disease, tomato leaf mold in the agricultural chemicals registration control.
Osthole (Osthol) is the main active ingredient of samphire frutus cnidii fruit, it also is a kind of important medical material, has broad-spectrum antibacterial action, beard and hair, toe, crissum tinea bacterium there is stronger inhibitory action, Trichomonas vaginalis also there is inhibitory action, and has antimycotic, resistance attitude, the effect such as antitumor.Registered control for powdery mildew of cucumber and insect pest on agricultural chemicals.
Although the registration use in agricultural chemicals of jamaicin and Osthole is compared with the conventional chemical agricultural chemicals, still there is the problem that effect is slow, preventive effect is low, the product on market is compared and is lacked competitiveness.Trace it to its cause, mainly be: the one, active ingredient is single, and preventive effect is limited, and germ develops immunity to drugs easily after long-term the use; The 2nd, preparation processing technology existing problems, so that the active ingredient of these natural botanical components is unstable, the plant absorbing availability is low.Jamaicin is two kinds of fully identical, not close compounds of chemical constitution with Osthole, therefore the mechanism of action is different, can avoid and delay germ after the present invention is mixed them develops immunity to drugs to these two kinds of active ingredients, simultaneously, after being mixed, these two kinds of active ingredients also have significant synergies, not only control efficiency can be improved, the consumption of these resource-type active ingredients can also be reduced.In addition, the present invention has also added antioxidant to increase the stability of product in product; Added short penetrant azone to improve crop to absorption and the utilization ratio of active ingredient.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of botanical fungicide,
Jamaicin and these two kinds of active ingredients of Osthole are mixed and add antioxidant and short bleeding agent, reach the purpose that improves product stability and control efficiency, reduce effective ingredient consumption, delaying drug resistance economizes on resources.
Above-mentioned technical purpose is achieved through the following technical solutions, a kind of botanical fungicide, and the component following by content forms:
Jamaicin 0.4～8wt%;
Osthole 0.2～8wt%;
Azone 3wt%;
Surfactant 10wt%;
Antioxidant 0.005wt%;
Preservative 0.5wt%;
Organic solvent 24.5～73.6wt%;
Surplus is water.
This is mixed in the botanical fungicide, the mass ratio of jamaicin and Osthole is controlled at 1:20～20:1, these two kinds of active ingredients can (can directly be bought crude extract for the extract at any position of corresponding plant, the also available coptis, frutus cnidii extracts, extraction process is: vegetable material is pulverized, cross 20～40 mesh sieves, then mix in the ratio of 40～50wt% ethanol of the corresponding 6-10L of every kg feed material powder and infiltrate dissolving, refluxing extraction, the extract diacolation reclaims and gets final product), it also can be the smart low content raffinate that extracts in the process of medicine, but need to guarantee content and the proportioning of above-mentioned two kinds of active ingredients, then add successively organic solvent (ethanol, methyl alcohol etc.), surfactant (non-ionic surface active agent, such as ethoxylated nonylphenol class non-ionic surface active agent NP100, NP200 etc.), azone, antioxidant (2, the 6-BHT, claim again BHT or antioxidant 264), preservative sodium benzoate and water, stirring to obtain botanical fungicide of the present invention.
Compared with prior art, advantage of the present invention and beneficial effect are as follows:
1, is mixed by the botanical pesticide active ingredient with two kinds of different active ingredients, increases on the one hand and render a service, reduce the consumption of active ingredient, saved resource; On the other hand, stability and the control efficiency of botanical fungicide have been improved by in preparation, adding penetrating agent (azone), antioxidant etc.; Simultaneously, because the chemical constitution of two active ingredients is fully different, have different mechanism of action, also can avoid or delay phytopathogen after therefore being mixed and produce resistance;

2. Toxicity Determination and prescription screening
At first take the Phytophthora capsici germ as target, carry out the proportioning screening of jamaicin and Osthole.Its principle is: adopt the mycelial growth rate method mixture that water agar is measured these two kinds of single doses and different proportionings thereof to the establishment of Phytophthora capsici germ mycelial growth in concentration EC50 value, then adopt the abundant co-toxicity coefficient method of Sun Yun (SUN Y P, JOHNSON E R .Analysis of Joint Action of Insecticides Against House Flies. Journal of Economic Entomology, 1960, the 53:887-892.) mode of application of analysis mixture preparation:
The theoretical toxicity index TTI of mixture preparation
=∑ (toxicity index of certain medicine * mass percent of this pharmaceutically active ingredient in mixture)
The theoretical toxicity index of the actual toxicity index of co-toxicity coefficient CTC=(mixture of mixture/mixture) * 100
Wherein: CTC 〉=120 o'clock are synergistic effect; CTC≤80 o'clock are antagonism; 80＜CTC＜120 o'clock are summation action.
Then select the most obvious scheme that is mixed of synergistic effect again in the activity of indoor measurement to botrytis cinerea, powdery mildew of cucumber bacterium, wherein because the powdery mildew of cucumber bacterium is obligatory parasitic bacteria, the stripped cotyledon method of employing (Yang Xiaojun etc. medicament compares the biological activity determination method of powdery mildew of cucumber bacterium. hubei agricultural science .2004, (3): 71-74) measure, the results are shown in Table 1 and table 2.
The mixture preparation of table 1 jamaicin and Osthole acts on the formula indoor screening of Phytophthora capsici germ 
Result of the test shows, the co-toxicity coefficient of the mass ratio of jamaicin and Osthole between 1:20 ~ 20:1 is all greater than 120, explanation shows synergistic effect after both are mixed in this proportion, co-toxicity coefficient when its Berberine and Osthole are mixed in the ratio of 2:1 is maximum, be 167, synergistic effect is the most remarkable.
Table 2 jamaicin and the Osthole 2:1 mass ratio rear activity to other germs that is mixed
As shown in Table 2, jamaicin and Osthole are respectively 32.52 μ g/mL and 49.28 μ g/mL with the EC50 value that mass ratio 2:1 is mixed to powdery mildew of cucumber bacterium and botrytis cinerea, all show greater activity.The above results all is the experiments that come from vitro, and the effect of practical application is still needed will carry out in the land for growing field crops to test and carried out the preventive effect checking.
