Abstract
The invention relates to a germicide composition having synergistic effect, comprising (A) mandipropamid and (B) propamocarb hydrochloride or one of propamocarb hydrochloride hydrochlorides as an effective active component, wherein, the weight ratio of the A to B is 1-50: 80-1. According to the invention, auxiliary agents and an excipient are added in the effective active component to prepare wettable powder, water dispersion granule, and suspending agent for controlling oomycete diseases.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of bactericidal composition that contains mandipropamid amine and Propamocarb or propamocarb.
Technical background
Mandipropamid amine (cyazofamid), molecular formula: C
23H
22CINO
4, chemical name: 2-(4-chloro-phenyl)-N-[2-(3-methoxyl group-4-(2-third alkynyloxy group)-phenyl-ethyl group]-2-(2-third alkynyloxy group)-acetamide.
Mandipropamid amine is acid amide fungicides.Its mechanism of action is for suppressing the biosynthesis of phosphatide, and leaf portion and fruit disease that exhausted big number is caused by oomycetes all have good preventive effect.The spore that is in the sprouting stage is had higher activity, and can suppress mycelia and grow up and sporulation.Can be absorbed rapidly through blade, and rested in the leaf table wax coat, blade is shielded.
Propamocarb (propamocarb), molecular formula are C
9H
21N
2O
2Cl, chemical name: 3-(dimethylamino) propyl carbamic acid propyl ester.
Propamocarb belongs to carbamates, mainly suppresses the biosynthesis of the phosphatide and the fatty acid of germ cell membrane component, suppresses mycelial growth, sporangial formation and sprouting.Inhale the conductivity bactericide in Propamocarb belongs to, when handling, can be absorbed by blade very soon and be distributed in the blade, play a protective role rapidly as cauline leaf.
Propamocarb (propamocarb hydrochloride), molecular formula: C
9H
21N
2O
2Cl, chemical name: propyl group-3-(dimethylamino) propyl carbamic acid hydrochloride.
Propamocarb low toxicity, safety have local preferably systemic action, and its mechanism of action is to suppress the phosphoric acid of germ cell membrane component and synthesizing of fatty acid, suppresses mycelial growth and spreads and sporangial formation and spore germination.Propamocarb is a kind of wide-spectrum bactericide, and is effective especially to algae Gammaproteobacteria fungi, and, fungies such as dish stalk mould, downy mildew, epidemic disease mould, corruption mould mould to tow all have good killing action.
No matter be mandipropamid amine, Propamocarb or propamocarb, long-term use separately makes disease develop immunity to drugs easily, causes the problem that dosage strengthens, preventive effect reduces, the lasting period shortens, and is unfavorable for environment sustainable development.And a kind ofly do not have the novel pesticide of cross resistance to prevent and treat pathogen if want newly developed, and then need screen 10,000～1.5 ten thousand compounds, expensive 1～1.5 hundred million dollar, the construction cycle is 6～10 years.And that the active ingredient of different effects mechanism is carried out is 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 more significantly filled a prescription, and can obviously improve preventive effect, reduces the dosage of agricultural chemicals greatly, also can enlarge fungicidal spectrum, improves germicidal efficiency.
Mandipropamid amine is different with the Propamocarb or the propamocarb mechanism of action, and each other composite have good synergistic effect within the specific limits.And composite about mandipropamid amine and Propamocarb or propamocarb do not see relevant report at present at home and abroad as yet.

Embodiment
Below in conjunction with embodiment the present invention is further explained, but the present invention is not limited thereto.Percentage in following examples all is weight percentage.
The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Practice example one: mandipropamid amine and Propamocarb (or propamocarb) are composite to the cucumber downy mildew Toxicity Determination
After the effective inhibition concentration scope of each medicament was confirmed in prerun, each medicament was established 6 dosage respectively by active constituent content and is handled, and established the clear water contrast.Carry out with reference to " agricultural chemicals indoor bioassay test rule bactericide ", adopt the mycelial growth rate method to measure the virulence of medicament cucumber downy mildew.Measure colony diameter with the right-angled intersection method behind the 72h, calculate and respectively handle clean amount of growth, mycelial growth inhibition rate.
Clean amount of 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 the EC of every kind of medicament thus
50Value.Calculate the different proportioning synergy ratios (SR) of two medicaments according to the Wadley method simultaneously, SR＜0.5 is an antagonism, and 0.5≤SR≤1.5 are summation action, and SR＞1.5 are synergistic effect.Computing formula is following:
Wherein: a, b are respectively mandipropamid amine and Propamocarb (or propamocarb) shared ratio in combination
A is a mandipropamid amine
B is Propamocarb (or propamocarb)
Result of the test is as shown in the table:
