Abstract
The invention relates to a bactericidal composition with synergy, which contains ethirimol and penconazole serving as effective active components, wherein the weight ratio of ethirimol to penconazole is 5-80:40-1. The effective active components are added with additives and excipients and prepared into wettable powder, water dispersible granules or suspending agents which are mainly used to prevent and control powdery mildew, cladosporium cucumerinum or anthracnose of vegetables and fruit trees.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of bactericidal composition on crop pest that contains the phonetic phenol of second and penconazole.
Technical background
The phonetic phenol of second (ethirimol) is the miazines bactericide of Syngenta Co.,Ltd's exploitation.Molecular formula is C
11H
19N
3O, chemical name: 5-butyl-2-ethylamino-4-hydroxyl-6-methylpyrimidine.
The phonetic phenol of second belongs to adenosine deaminase inhibitors.Be a kind of systemic fungicide, have preventive and therapeutic action.Can be absorbed rapidly by plant roots, stem, leaf, and in plant corpus, run to each position.
Penconazole (penconazole) molecular formula: C
13H
15Cl
2N
3, chemical name: 1-[2-(2,4-dichlorophenyl)-4-propyl group-DOX-2-methyl]-1-hydrogen-1,2, the 4-triazole.
Penconazole belongs to three nitrogen heterocycles bactericide, is sterol demethylation inhibitor, destroys and stop the biosynthesis of the cell membrane important composition composition ergosterol of germ, causes cell membrane not form, and is that germ is dead.Root, stem, leaf isoreactivity tissue by crop absorb, and can upwards conduct with body fluid in the plant body soon.
No matter be the phonetic phenol of second, penconazole or other efficient germicides, long-term separately use easily makes disease develop immunity to drugs, and causes the problem that dosage strengthens, preventive effect reduces, the lasting period shortens, and is unfavorable for environment sustainable development.The active ingredient of the different mechanisms of action is carried out composite, is to delay the disease method commonly used that develops immunity to drugs, and according to the effect in the production application, judge this composite be synergistic effect or antagonism.Complex role is significantly filled a prescription, and can obviously improve preventive effect, greatly reduces the dosage of agricultural chemicals, also can enlarge fungicidal spectrum, improves germicidal efficiency.The phonetic phenol of second is different from the penconazole mechanism of action, and mutually composite have good synergistic effect within the specific limits.And composite about the phonetic phenol of second and penconazole there is not yet relevant report at present at home and abroad.
Summary of the invention
The objective of the invention is to propose a kind of have synergistic function, use cost is low, preventive effect the is good bactericidal composition that contains the phonetic phenol of second and penconazole.
The present invention is achieved through the following technical solutions:
A kind of bactericidal composition that contains the phonetic phenol of second and penconazole, wherein the phonetic phenol of second and penconazole weight ratio are 5～80: 40～1.
The described bactericidal composition that contains the phonetic phenol of second and penconazole, wherein the weight ratio of the phonetic phenol of second and penconazole is 10～70: 30～1.
The described bactericidal composition that contains the phonetic phenol of second and penconazole, wherein the weight ratio of the phonetic phenol of second and penconazole is 20～60: 20～1.
The described bactericidal composition that contains the phonetic phenol of second and penconazole is made wetting powder, water dispersible granules or suspending agent.
When making wetting powder, composition comprises following constituent content: the phonetic phenol 5～80% of second, penconazole 1～40%, dispersant 5～10%, wetting agent 2～10%, filler 8～90%.
The phonetic phenol of second, penconazole, dispersant, wetting agent, filler are mixed, in mixed cylinder, mix, after airslide disintegrating mill is pulverized, mix again, namely can be made into the phonetic phenol penconazole of second wetting powder product.
When making water dispersible granules, composition comprises following constituent content: the phonetic phenol 5～80% of second, penconazole 1～40%, dispersant 3～12%, wetting agent 1～8%, disintegrant 1～10%, filler 10～90%.
The phonetic phenol of second, penconazole, dispersant, wetting agent, disintegrant, filler etc. are obtained together the particle diameter of needs through air-flow crushing, obtain the materials of granulating.With item quantitatively send in the fluidized bed granulation dryer through granulation and drying after, make the phonetic phenol penconazole of second water dispersible granules product.
Comprise following constituent content when composition is made suspending agent: the phonetic phenol 5～50% of second, penconazole 1～20%, dispersant 2～10%, wetting agent 2～10%, defoamer 0.1～1%, thickener 0.1～2%, antifreeze 0.1～8%, deionized water add to 100%.

Implementation of an application example two: the phonetic phenol of second and penconazole are composite to the powdery mildew of cucumber Toxicity Determination
Test medicine provides by Shaanxi means of agricultural production trade Co., Ltd of U.S. nation.
After each medicament establishment concentration range was determined in prerun, each medicament was established respectively 5 dosage by active constituent content and is processed, and established the clear water contrast.Carry out with reference to " farm-chemical indoor determination test rule bactericide ", adopt the mycelial growth rate method to measure medicament to the virulence of powdery mildew of cucumber.Measure colony diameter with the right-angled intersection method behind the 72h, calculate and respectively process net growth, mycelial growth inhibition rate.
Net growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), and liquor strength (μ g/mL) converts logarithm value (x) to, tries to achieve virulence regression equation (y=a+bx) with method of least squares, and calculates thus the EC of every kind of medicament
50Value.Calculate the different proportioning synergy ratios (SR) of two medicaments according to the Wadley method simultaneously, SR＜0.5 is antagonism, and 0.5≤SR≤1.5 are summation action, and SR＞1.5 are synergistic effect.Computing formula is as follows:
Wherein: a, b are respectively the phonetic phenol of second and penconazole shared ratio in combination
A is the phonetic phenol of second
B is penconazole
Result of the test is as shown in table 1:
The phonetic phenol of table 1 second, penconazole and composite toxicity test analysis of results table to powdery mildew of cucumber thereof
As shown in Table 1, the phonetic phenol of second, penconazole are to the EC of powdery mildew of cucumber
50Be respectively 43.68mg/ and 0.18mg/L.The virulence of the phonetic phenol of second is lower than the virulence of penconazole.1: 1,5: 1,10: 1,15: 1,20: 1 synergy ratio of the phonetic phenol of second and penconazole proportioning is respectively 1.56,1.96,2.24,1.83,1.52, illustrating that the phonetic phenol of second and penconazole were mixed in the scope at 1: 1 to 20: 1 all shows obvious synergistic effect, wherein synergy ratio SR is maximum when the phonetic phenol of second and penconazole weight ratio are 10: 1, and synergistic effect is the most obvious.
