The effective active ingredients of the fungicide composition contain pyrimorph and cymoxanil, wherein the weight ratio of the pyrimorph to the cymoxanil is 1-80:80-1; and the effective active ingredients are added with an aid and an excipient to be prepared into wettable powder, water dispersible granules and suspending agents, and are mainly used for preventing and controlling downy mildew, phytophthora blight and the like of fruits and vegetables.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of bactericidal composition that contains fourth pyrrole morpholine and white urea cyanogen.
Technical background
Oomycetes is characteristics such as more serious pathogenic takes place the class in the present agricultural production, and it has short from generation to generation, and sporulation quantity is big, and the incubation period is short, is infecting often, and is destructive strong to host plant, and epidemic rate is fast.Can cause plurality of plant diseases, as downy mildew, eqpidemic disease etc.Bring very serious economy loss to agricultural.

2, chemical name:
(E)-3-(2-chloropyridine-4-yl)-3-(4-tert-butyl-phenyl)-acryloyl morpholine.
Structural formula is:
Fourth pyrrole morpholine is one of domestic novel pesticide that has China's independent intellectual property right few in number, and its mechanism of action causes protoplasm seepage in the cell for by changing the permeability of cell wall, and it is synthetic to suppress mycelium protein matter simultaneously, thereby suppresses mycelial growth.Fourth pyrrole morpholine has excellent preventive effect to oomycetes order fungi, and fungicidal spectrum is wide, can be used for preventing and treating various crop diseases such as cucumber downy mildew, tomato late blight and capsicum epidemic disease, and damping off, melon gray mold are also had good effect.
But no matter be fourth pyrrole morpholine or other efficient germicides, 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 that the active ingredient of the different mechanisms of action 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.
Summary of the invention
The objective of the invention is to propose a kind of generation or delaying drug resistance speed that can prevent disease drug resistance, the bactericidal composition that contains fourth pyrrole morpholine that use cost is low, preventive effect is good.
The inventor is by a large amount of indoor biometricses and field control effectiveness test, finds the use that is mixed within the specific limits of fourth pyrrole morpholine and white urea cyanogen unexpectedly, and diseases such as downy mildew, eqpidemic disease are had good synergistic effect.

Embodiment
To further instruction of the present invention, but the present invention is not limited thereto below in conjunction with embodiment.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.
Implementation of an application example one: fourth pyrrole morpholine and white urea cyanogen are composite to the cucumber downy mildew Toxicity Determination
After the effective inhibition concentration scope of each medicament was determined in prerun, each medicament was established 7 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 as follows:
Wherein: a, b are respectively fourth pyrrole morpholine and white urea cyanogen shared ratio in combination
A is a fourth pyrrole morpholine
B is white urea cyanogen
Result of the test is as shown in the table:
Table 1 fourth pyrrole morpholine, white urea cyanogen and composite toxicity test analysis of results table thereof to cucumber downy mildew
As shown in Table 1, fourth pyrrole morpholine, white urea cyanogen are to the EC of cucumber downy mildew
50Be respectively 1.35mg/L and 1.26mg/L.Fourth pyrrole morpholine and white urea cyanogen proportioning were mixed in the scope at 8: 1～1: 8 and all show obvious synergistic effect, synergy ratio SR maximum when fourth pyrrole morpholine and white urea cyanogen weight ratio are 1: 1 wherein, and synergistic effect is the most obvious.
