Abstract
The invention discloses a pesticide composition for prevention and treatment of tomato late blight. Through combination of Penibruguieramine A and bulbocapnine at certain ratio, an excellent effect of synergistically preventing and treating the tomato late blight is found. Especially, when the weight part ratio of the Penibruguieramine A to the bulbocapnine is 17:1-20:1, the synergistic effect is very significant.
Description
Technical field
The present invention relates to a kind of medicament, specifically a kind of preventing and treating tomato late blight composition pesticide, belong to agricultural technology neck
Domain.
Background technology
Tomato late blight is one of important disease on tomato, and some areas occur.Tomato late blight protecting field, open country
Occur, but main harm tomato in greenhouse.Time harm more than continuous rainy weather is serious.Cause stem rotten when falling ill serious
Rotten, plant is wilted and fruit becomes brown, affects yield.
Actual agricultural chemicals experience have shown that, repeats and single-minded applies a kind of reactive compound to prevent and treat harmful fungoid very
To cause the fast selective of fungal bacterial strain in the case of many, be that reduction refractory fungal bacterial strain is selectively dangerous, at present generally
Harmful fungoid is prevented and treated using the mixture of different activities compound.By the way that the reactive compound with the different mechanisms of action is entered
Row combination, can delaying drug resistance produce, reduce amount of application, reduce cost accounting.Natural active compound is killed as a kind of emerging
Bacterium insecticide, particularly natural active compound are compounded for the impact of pesticide-germicide, are current pesticide field primary studies
Direction.
Compound Penibruguieramine A are published in Org.Lett.2014, and 16,1390-1393, the compound is gathered around
There are brand-new framework types, yet there are no with regard to Penibruguieramine A and bulbocapnine late with preventing and treating tomato
Report in terms of epidemic disease.
The content of the invention
For the problem that above-mentioned prior art is present, it is an object of the invention to provide containing Penibruguieramine
A prevents and treats the bactericidal composition of tomato late blight, and preventing and treating tomato late blight effect is good.
To realize the purpose of the present invention, inventor compounds Penibruguieramine A and bulbocapnine, for preventing and treating
The disease of crop.
To achieve these goals, the technical solution used in the present invention is：One kind includes two kinds of principle active components：
Penibruguieramine A and bulbocapnine, Penibruguieramine A structural formulas are as follows：
Described Penibruguieramine A are with the ratio of the parts by weight of bulbocapnine, 1:1-30:1.
Described Penibruguieramine A account for the 1-6% of bactericide gross weight with the weight sum of bulbocapnine.
The present invention under specific ratio by Penibruguieramine A and bulbocapnine compatibility by having found have very
The effect of good collaboration preventing and treating tomato late blight, particularly in Penibruguieramine A and the parts by weight of bulbocapnine
Ratio be 17:1-20:Between 1, its collaboration preventing and treating tomato late blight effect is apparent, and toxicity is less.
Specific embodiment
The preparation method of compound Penibruguieramine A involved in the present invention is referring to document：
Penibruguieramine A,a Novel Pyrrolizidine Alkaloid from the Endophytic Fungus
Penicillium sp.GD6Associated with Chinese Mangrove Bruguiera gymnorrhiza are delivered
In Org.Lett.2014,16,1390-1393.
Bulbocapnine, No. CAS：298-45-3.
Embodiment 1：
Active ingredient Penibruguieramine A and bulbocapnine, with the customary adjuvant such as lignin, diatomite according to normal
Rule technique, makes the wettable powder that effective constituent concentration is 2%.
Embodiment 2：
Active ingredient Penibruguieramine A and bulbocapnine, with calcium dodecyl benzene sulfonate, phenethyl phenol polyoxy
The customary adjuvants such as vinethene, solvent naphtha make the missible oil that effective constituent concentration is 2% according to common process.
Embodiment 3：
Active ingredient Penibruguieramine A and bulbocapnine, press with the customary adjuvant such as wooden sodium sulfonate, kaolin
More solito technique, makes the water dispersible granules that effective constituent concentration is 2%.
Embodiment 4：
Active ingredient Penibruguieramine A and bulbocapnine, it is conventional with solvent naphtha, pyrrolidones, xanthans etc.
Auxiliary material makes the aqueous emulsion that effective constituent concentration is 2% according to common process.
Embodiment 5
Active ingredient Penibruguieramine A and bulbocapnine, with methyl oleate, polyoxyethylene (30) dimerization hydroxyl
The customary adjuvants such as stearate make the aqueous emulsion that effective constituent concentration is 2% according to common process.
Laboratory test：
Subjects：Tomato late blight germ
The incidence of tomato seedling is investigated according to test grade scale, disease index and prevention effect is calculated.By preventing and treating effect
Fruit is converted into niqueMin (y), and liquid does height (μ g/ml) and is converted into logarithm value (x), with least square method calculate virulence equation and
Concentration EC50 in suppression, according to the abundant methods of Sun Yun toxicity index level co-toxicity coefficient (CTC) of medicament is calculated.
Actual measurement toxicity index (ATI)=(standard agent EC50/ reagent agents EC50) * 100
Percentage composition+B medicament toxicity index * the mixtures of A in theoretical toxicity index (TTI)=A medicament toxicity index * mixtures
The percentage composition of middle B
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] * 100CTC≤
80, composition shows as antagonism, 80 ＜ CTC ＜ 120, and composition shows as summation action, CTC >=120, composition performance
For synergistic effect.
Table 1Penibruguieramine A：Bulbocapnine and its different ratio compounding are tied to tomato late blight toxicity test
Fruit is analyzed.
A is Penibruguieramine A, and B is bulbocapnine.
From the measurement result of table 1, as Penibruguieramine A：Bulbocapnine proportioning is 17:1-20:Between 1
When, co-toxicity coefficient is both significantly higher than 200, and with obvious synergistic effect, and other ratios mix, and co-toxicity coefficient is not obvious.
Field efficacy checking test
Test method：At the initial stage of a disease, first time spraying being carried out immediately, second dispenser being carried out after 7 days, each processes 4
Individual cell, each square meter of cell 20.10 days investigation statisticses incidences before medicine and after second medicine, 5 points of each cell is random
Sampling, 5 plants of crops of per investigation, investigates the lesion area in whole strain per blade and accounts for the percentage of blade area and be classified, and calculates
Disease index and prevention effect.
Grade scale：
0 grade：Disease-free spot；
1 grade：Leaf spot lesion is less than 5, and length is less than 1cm；
3 grades：Leaf spot lesion 6-10, part scab length is more than 1cm；
5 grades：Leaf spot lesion 11-25, part scab is linked to be piece, and lesion area accounts for the 10-22% of leaf area；
7 grades：Leaf spot lesion more than 26, scab is linked to be piece, and lesion area accounts for the 26-50% of leaf area；
9 grades：Scab is linked to be piece, and lesion area accounts for more than the 50% of leaf area or full leaf is withered.
The field control effectiveness test of embodiment and control group to tomato late blight.
It can be seen that Penibruguieramine A are with bulbocapnine, and the proportioning under certain proportion cooperates with preventing and treating Phytophthora infestans
Sick effect is apparent, and single Penibruguieramine A have certain prevention effect, but effect does not show
Write, the anti-tomato late blight ability of single bulbocapnine is also effect on driving birds is not good.Penibruguieramine A and bulbocapnine
The ratio of parts by weight is 17:1-20:Synergy is most notable when 1, and effect is not very notable during other proportions.
