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 ZJ0712 and prochloraz-manganese chloride complex.
Technical background
ZJ0712 (kresoxim-methyl) is the methoxy acrylic new type bactericide with independent intellectual property right that China formulates voluntarily.Molecular formula: C
20H
22O
4, chemical name: (E) 2-[2-(2,5-dimethyl phenoxy toluene)-phenyl]-3-methoxy-methyl acrylate.
ZJ0712 belongs to the cell mitochondrial respiration inhibitor, and shift through the electronics in the pathogen physiological activity and suppress mitochondrial respiratory, and the supply of interference cell energy, make the pathogen cell death.Tool protection and therapeutic action, toxicity is low, and active high, fungicidal spectrum is wide, and the plurality of plant diseases that sac fungi, flagellum mattress and imperfect fungus are caused has the better prevention effect, particularly powdery mildew of cucumber and downy mildew of garpe is had very excellent preventive effect.
Prochloraz-manganese chloride complex (prochloraz-manganese chloride complex) is to be composited by Prochloraz and manganese chloride, is the imidazoles broad-spectrum germicide.Pure article are dark-brown crystalloid solid.Molecular formula is [C
15H
16C
13N
3O
2] 4MnCl
2, chemical name is: N-propyl group-N-[2-(2,4, the 6-Trichlorophenoxy) ethyl]-1H imidazoles-1-formamide-manganese chloride.
Prochloraz-manganese chloride complex works through the biosynthesis that suppresses sterol; Although it does not have systemic action; But has certain conductive performance; Mushroom brown rot, mango anthracnose, oranges and tangerines penicilliosis, anthracnose there are special control efficiency, also can be used for fruit and adopt post processing, control storage period disease.In soil, mainly be degraded to volatile metabolite, be prone to be difficult for being dashed pouring,, but the fungi in some soil is had inhibitory action the biological low toxicity in the soil by soil by soil particle absorption.
No matter be ZJ0712, prochloraz-manganese chloride complex 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.The active ingredient of different effects mechanism 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 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.ZJ0712 is different with the prochloraz-manganese chloride complex mechanism of action, and each other composite have good synergistic effect within the specific limits.And composite about ZJ0712 and prochloraz-manganese chloride complex do not see relevant report at present at home and abroad as yet.
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 ZJ0712 and prochloraz-manganese chloride complex.
The present invention realizes through following technical scheme:
A kind of bactericidal composition that contains ZJ0712 and prochloraz-manganese chloride complex, wherein ZJ0712 and prochloraz-manganese chloride complex weight ratio are 1-50: 1-80.
The described bactericidal composition that contains ZJ0712 and prochloraz-manganese chloride complex, wherein the weight ratio of ZJ0712 and prochloraz-manganese chloride complex is 1-30: 15-70.
The described bactericidal composition that contains ZJ0712 and prochloraz-manganese chloride complex, wherein the weight ratio of ZJ0712 and prochloraz-manganese chloride complex is 1-20: 30-60.
The described bactericidal composition that contains ZJ0712 and prochloraz-manganese chloride complex is processed wetting powder, water dispersible granules.
When processing wetting powder, composition comprises following constituent content: ZJ0712 1～50%, prochloraz-manganese chloride complex 10～80%, dispersant 5～10%, wetting agent 2～10%, filler 8～90%.
ZJ0712, prochloraz-manganese chloride complex, dispersant, wetting agent, filler are mixed, in mixed cylinder, mix, after airslide disintegrating mill is pulverized, mix again, promptly can be made into ZJ0712 prochloraz-manganese chloride complex wetting powder product.

Practice example two: ZJ0712 and prochloraz-manganese chloride complex 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 the effective inhibition concentration scope of each medicament was confirmed in prerun, each medicament was established 5 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 powdery mildew of cucumber.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 ZJ0712 and prochloraz-manganese chloride complex shared ratio in combination
A is a ZJ0712
B is a prochloraz-manganese chloride complex
Result of the test is as shown in table 1:
