Abstract
The invention discloses a kind of bactericidal composition containing tiadinil, the bactericidal composition that contains active components A and active component B, active components A is selected from tiadinil, active component B is selected from following any one compound: dimethomorph, metalaxyl and salt, Propamocarb and salt, white urea cyanogen, and the weight ratio of active components A and active component B is 1 ︰ 80 ~ 60 ︰ 1. The present composition has greater activity to the multiple diseases in various crop, and has obvious synergistic effect, has expanded fungicidal spectrum, and has that dosage is little, resistance of rainwater washing against, the obvious feature of synergy.<!--1-->
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of bactericidal composition containing tiadinil cropApplication in disease.
Technical background
Tiadinil (Tiadinil), molecular formula: C11H10ClN3OS, chemical name: 3'-is chloro-4,4'-dimethyl-1,2,3-thiadiazoles-5-formailide, this medicament has well interior absorption, canBy root absorption, and be transmitted to rapidly other positions, be suitable for the water surface and use, the lasting period is long,Leaf blast disease and fringe rice blast are had to good prevention effect.
Dimethomorph (Dimethomorph) chemical name: (E, Z)-4-[3-(4-chlorphenyl) 3-(3,4-Dimethoxyphenyl) acryloyl] morpholine, molecular formula: C21H22ClNO4, this product is single-minded ovicidal bacteriumGuiding principle fungi bactericide, its effect feature is to destroy the formation of cell envelope, to oomycetes history of lifeThere is effect in each stage, particularly responsive at the formation stages of sporangiophore and egg spore, at the utmost pointUnder low concentration, (< 0.25 μ g/ml) is suppressed. With phenylamide medicament without cross resistance.
Metalaxyl (Metalaxyl) chemical name: D, L-N-(2,6-3,5-dimethylphenyl)-N-(2'-firstOxygen base acetyl) methyl lactamine, molecular formula: C15H21NO4. The salt of metalaxyl refers to Metalaxyl-M(Metalaxyl-M) chemical name: N-(2,6-xylyl)-N-(methoxyl group acetyl group)-D-alanine methyl esters. The systemic fungicide of metalaxyl and the protection of salt tool and therapeutic action, can quiltThe root of plant, stem, leaf absorb, and transfer to each device of plant with moisture content in plantOfficial, can do cauline leaf processing, seed treatment and soil treatment, to downy mildew, phytophthora,The caused disease of pythium spp is effective.
Propamocarb (Propamocarb) chemical name: 3-(dimethylamino) propyl carbamic acid thirdEster, molecular formula: C9H21N2O2Cl. The salt of Propamocarb refers to propamocarb (PropamocaRbhydrochloride) chemical name: propyl group-3-(dimethylamino) propyl carbamic acid saltHydrochlorate. Propamocarb and salt have local systemic action, also can be used as impregnation process and seed protectionAgent.
Frost urea cyanogen (cymoxanil) chemical name: 2-cyano group-N-[(ethylamino-) carbonyl]-2-(methoxyl groupImido grpup) acetamide, molecular formula: C7H10N4O3.

By mutual to active component B dimethomorph, Propamocarb and salt, metalaxyl and salt in table 1 ~ 7, white urea cyanogenChange, can make novel formulation.
The embodiment of the present invention is the method that adopts Toxicity Determination and field test to combine. First pass throughToxicity Determination, the synergy ratio (SR) after clear and definite two kinds of medicaments are composite by a certain percentage,SR < 0.5 is antagonism, and 0.5≤SR≤1.5 are summation action, and SR > 1.5 is synergistic effect, on this basis, then carry out field test.
Test method: after the effective inhibition concentration scope of each medicament is determined in prerun, medicament is by active ingredientContent is established respectively 5 dosage processing, establishes clear water contrast. With reference to " farm-chemical indoor determination testCriterion bactericide " carry out, adopt mycelial growth rate method to measure the virulence of medicament to crop germ. After 72h, measure colony diameter by right-angled intersection method, calculate each processing net growth, mycelial growthInhibiting rate.
Net growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), and it is right that liquor strength (μ g/mL) converts toNumerical value (x), is tried to achieve virulence regression equation (y=a+bx) with least square method, and calculates thusGo out the EC of every kind of medicament50Value. Calculate the different proportioning synergies of two medicaments according to Wadley method simultaneouslyRatio (SR), SR < 0.5 is antagonism, 0.5≤SR≤1.5 are summation action, SR > 1.5 be synergistic effect. Computing formula is as follows:
Wherein: a, b are respectively active components A and active component B shared ratio in combination;
A is tiadinil;
B selects to the one in dimethomorph, Propamocarb and salt, white urea cyanogen, metalaxyl and salt.
