Description
Technical field
The invention belongs to technical field of pesticide, it relates to a kind of containing the fungicidal composition of benziothiazolinone and own azoles alcohol.
Technical background
Benziothiazolinone (Benziothiazolinone) is the heterocyclic nitrogen-group fungicide of Shaanxi Xi great HuaTe Science Industrial Co., Ltd. exploitation. Molecular formula: C7H5NOS, chemical name: 1,2 benzisothiazole-3-ketones.
Benziothiazolinone is a kind of efficient, wide-spectrum bactericide, has and destroys germ nuclear structures, and interference germ cell metabolism so that it is physiologic derangement causes germ dead.
Own azoles alcohol (Hexaconazole) is the triazole bactericidal agent of Syngenta Co., Ltd's exploitation. Molecular formula: C14H17Cl2X3O, chemical name: (RS)-2-(2,4 dichloro benzene base)-1-(1H-1,2,4-triazol-1-yl)-own-2-alcohol.
Own azoles alcohol belongs to sterol demethylation inhibitors, destroys and stops the biosynthesizing of the cytolemma important composition composition ergosterol of germ, cause cytolemma not formed, and makes germ dead. Suction, protective material therapeutic activity in tool.
No matter be benziothiazolinone, own azoles alcohol or other efficient germicides, be used alone for a long time, it is easy to disease is developed immunity to drugs, cause dosage to strengthen, anti-effect reduces, the problem of lasting period shortening, is unfavorable for environment sustainable development. The effective constituent of the different mechanism of action carries out mixture, is delay disease to develop immunity to drugs conventional method, and judges that this mixture is synergism or antagonistic action according to the effect in production application. Mixture effect is significantly filled a prescription, it is possible to significantly improve anti-effect, greatly reduces the dosage of agricultural chemicals, also can expand fungicidal spectrum, it is to increase germ-killing efficiency. Benziothiazolinone destroys germ nuclear structures, and own azoles alcohol acts on the cytolemma of germ, and the mechanism of action is different, and mutual mixture has good synergism within the specific limits.
Summary of the invention
It is an object of the invention to propose a kind of have synergistic function, use cost effect low, anti-good containing the fungicidal composition of benziothiazolinone and own azoles alcohol.
The present invention is achieved through the following technical solutions:

The useful effect of the present invention: (1) present composition effective active composition benziothiazolinone belongs to the sterilant of two kinds of different mechanisms of action from own azoles alcohol, both mutual mixtures can not produce to conflict;(2) present composition has good synergism within the specific limits, and anti-effect is higher than single dose, and dosage is little; (3) the present invention does not use organic solvent, not easily produces poisoning, is convenient to transport and storage; (4) Powdery Mildew of vegetables and fruit tree, gray mold, black spot are had special efficacy by the present composition.
Embodiment
Below in conjunction with embodiment to further instruction of the present invention, the per-cent in embodiment is all weight percentage, but the present invention is not limited thereto.
The embodiment of the present invention is the method adopting Toxicity Determination and field test to combine.
Implementation of an application example one
Benziothiazolinone and own azoles alcohol mixture are to powdery mildew of cucumber Toxicity Determination.
Test medicine all has Shaanxi Xi great HuaTe Science Industrial Co., Ltd. to provide.
Determining after the effective inhibition concentration scope of each medicament through prerun, each medicament establishes 5 dosage process respectively by active constituent content, if clear water comparison. Carry out with reference to " farm-chemical indoor determination test rule sterilant ", adopt mycelial growth rate method to measure medicament to the virulence of powdery mildew of cucumber. Measure colony diameter with cross interior extrapolation after 72h, calculate each process net growth, mycelial growth inhibition rate.
Net growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), liquor strength (�� g/mL) converts logarithmic value (x) to, try to achieve virulence regression equation (y=a+bx) with method of least squares, and thus calculate the EC50 value of often kind of medicament. Colleague calculates two medicaments different ratio synergy ratio (SR) according to Wadley method, and SR < 0.5 is antagonistic action, and 0.5��SR��1.5 are summation action, and SR > 1.5 is synergism. Calculation formula is as follows:
Wherein: a, b are respectively own azoles alcohol and benziothiazolinone ratio shared in combination
A is own azoles alcohol
B is benziothiazolinone
Test-results is as shown in table 1:
The own azoles alcohol of table 1, benziothiazolinone and mixture thereof are to the toxicity test analysis of results table of powdery mildew of cucumber
As shown in Table 1, the EC50 of powdery mildew of cucumber is respectively 0.18mg/L and 32.38mg/L by own azoles alcohol, benziothiazolinone. The virulence of own azoles alcohol is higher than the virulence of benziothiazolinone. The synergy ratio of own azoles alcohol and benziothiazolinone proportioning 1: 1,1: 5,1: 10,1: 20,1: 30 is respectively 1.66,1.89,2.06,1.86,1.54, illustrate that own azoles alcohol and benziothiazolinone mixture in 1: 1-1: 20 scopes all shows obvious synergism, wherein when own azoles alcohol and benziothiazolinone weight ratio are 1: 10, synergy ratio SR is maximum, and synergism is the most obvious.
