The composition has relatively high activity on various diseases of various crops and has an obvious synergistic effect, and the bactericidal spectrum is enlarged. The composition has characteristics of small dosage, rainwash resistance and obvious synergism.
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 polyoxin and iprovalicarb.
Technical background
Iprovalicarb (iprovalicarb); chemical name: 2-methyl isophthalic acid-[(1-p-methylphenyl ethyl) carbamoyl]-(S)-propyl carbamic acid isopropyl ester; it is a kind of amino acids bactericide; the mechanism of action is the amino acid whose metabolism of impact; different from known biocides, with the bactericide such as metalaxyl without cross resistance.Polyoxin is by the growth that suppresses sporangium plumule pipe, mycelial growth and sporulation two performances protection, the therapeutic action to crop.Can effectively prevent and treat the microbial disease of Oomycete cause of disease.
Polyoxin (polyoxin) is the metabolite that streptomyces aureus produces, and belongs to the broad-spectrum antibiotics series bactericidal agent.Inhale conduction in having preferably.Its mechanism of action is to disturb the chitinous biosynthesis of germ cell wall, makes the somatic cells wall can not carry out biosynthesis and causes germ dead.Germ tube is with after mycelia contacts medicament, and cell inclusion is expanded, breaks, overflowed in the part, and can not normal development, causes death.Therefore also has the effect that germ produces spore and scab expansion that suppresses.Be mainly used in preventing and treating cucumber downy mildew, powdery mildew, black fleck disease of ginseng, apple pear graywall and rice sheath blight disease.
In the real process of agricultural production, prevent and treat disease the problem of easy generation be the generation of disease drug resistance.The different cultivars composition carries out composite, is to prevent and treat the very common method of resistance disease.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.Reduce the risk that plant pathogenic fungi develops immunity to drugs, it is one of way of at present normal employing that the application synergistic composition is prevented and treated the noxious plant disease fungus.

Application Example two:
For trying disease: downy mildew of garpe, test medicine provides by the applicant, experimental scheme: the establishment concentration range of determining the two different proportioning mixture of polyoxin and iprovalicarb through preliminary experiment.
The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.First by Toxicity 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 are synergistic effect, on this basis, carry out field trial again.
Test method: after each medicament establishment concentration range was determined in prerun, medicament was established respectively 5 dosage by active constituent content and is processed, and established the clear water contrast.Carry out with reference to " farm-chemical indoor determination test rule bactericide ", adopt the mycelial growth rate method to measure medicament to the virulence of crop germ.Measure colony diameter with the right-angled intersection method behind the 72h, calculate and respectively process net growth, mycelial growth inhibition rate.
Net 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 thus the EC of every kind of medicament
50Value.Calculate the different proportioning synergy ratios (SR) of two medicaments according to the Wadley method simultaneously, SR＜0.5 is 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 active components A and iprovalicarb shared ratio in combination;
A is polyoxin;
The B iprovalicarb.
