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 phonetic phenol of second and ZJ0712.
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 prevention and therapeutic action.Can be absorbed rapidly by plant roots, stem, leaf, and in plant corpus, run to each position.
ZJ0712 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]-the 3-methoxy-methyl acrylate.
ZJ0712 belongs to the cell mitochondrial respiration inhibitor, and shift by 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, anthracnose and downy mildew of garpe is had very excellent preventive effect.
No matter be the phonetic phenol of second, ZJ0712 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 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 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.The phonetic phenol of second is different with the ZJ0712 mechanism of action, and mutually composite have good synergistic effect within the specific limits.And composite about phonetic phenol of second and ZJ0712 do not see relevant report at present at home and abroad as yet.

Implementation of an application example two: phonetic phenol of second and ZJ0712 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 determined 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 as follows:
Wherein: a, b are respectively the phonetic phenol of second and ZJ0712 shared ratio in combination
A is the phonetic phenol of second
B is a ZJ0712
Result of the test is as shown in table 1:
The phonetic phenol of table 1 second, ZJ0712 and composite toxicity test analysis of results table thereof to powdery mildew of cucumber
As shown in Table 1, the phonetic phenol of second, ZJ0712 are to the EC of powdery mildew of cucumber
50Be respectively 46.73mg/L and 0.12mg/L.The virulence of the phonetic phenol of second is lower than the virulence of ZJ0712.1: 2,1: 1,5: 1,10: 1,20: 1 synergy ratio of phonetic phenol of second and ZJ0712 proportioning is respectively 1.65,1.84,2.03,1.65,1.53, illustrating that phonetic phenol of second and ZJ0712 were mixed in the scope at 1: 2 to 20: 1 all shows obvious synergistic effect, synergy ratio SR maximum when the phonetic phenol of second and ZJ0712 weight ratio are 5: 1 wherein, synergistic effect is the most obvious.
