The invention has remarkable effects in preventing and curing rice sheath blight, rice blast, false smut, wheat powdery mildew, wheat stripe rust, wheat root rot, wheat sheath blight, big and small flecks of maize, sclerotinia sclerotiorum disease of rape, flecks and leaf cast of fruit tree, ring spot of fruit tree, anthracnose of fruit tree, tobacco black shank, tobacco brown spot, early and late blight of tomato, early and late blight of potato, etc..
Description
Technical field:
The present invention relates to a kind of agricultural chemicals.
Background technology:
All there is undesirable part in the existing agricultural chemicals of preventing and treating rice sheath blight disease, rice blast, false smut, wheat powdery mildew, stripe rust of wheat, root rotof flax, wheat sharp eyespot, corn northern leaf blight and southern leaf blight, sclerotinia rot of colza, fruit tree spot defoliation, fruit tree ring spot, fruit tree anthracnose, black shank, Alternaria alternate, tomato morning, late blight, potato morning, late blight medicine etc. on effect.
Summary of the invention:
The object of the present invention is to provide the bactericidal composition and the purposes of the good chlorine nalidixic bacterium ester of a kind of bactericidal effect.
Technical solution of the present invention is:
A kind of bactericidal composition of chlorine nalidixic bacterium ester is characterized in that: its drug ingedient is made up of chlorine nalidixic bacterium ester and metalaxyl class material.
The weight ratio of chlorine nalidixic bacterium ester and metalaxyl class material is 1～50: 1～60.
Described metalaxyl class material is metalaxyl or Metalaxyl-M.
A kind of bactericidal composition of chlorine nalidixic bacterium ester is prevented and treated rice sheath blight disease, rice blast, false smut, wheat powdery mildew, stripe rust of wheat, root rotof flax, wheat sharp eyespot, corn northern leaf blight and southern leaf blight, sclerotinia rot of colza, fruit tree spot defoliation, fruit tree ring spot, fruit tree anthracnose, black shank, Alternaria alternate, tomato morning, late blight, potato early, use in the late blight medicine in preparation.
Product of the present invention confirms to prevent and treat aspect rice sheath blight disease, rice blast, false smut, wheat powdery mildew, stripe rust of wheat, root rotof flax, wheat sharp eyespot, corn northern leaf blight and southern leaf blight, sclerotinia rot of colza, fruit tree spot defoliation, fruit tree ring spot, fruit tree anthracnose, black shank, Alternaria alternate, tomato morning, late blight, potato morning, the late blight through test, have fairly obvious effect, bactericidal effect is good.
Concrete test situation:
1, chlorine nalidixic bacterium ester mixes the effect to potato late blight with metalaxyl.
The mycelial growth rate method is adopted in test.The previously prepared inoculated by hypha block of picking is on the EPA of different drug concentrations culture medium flat plate, mycelia faces up, cultivated 8 days down at 19 ℃, check colony diameter, calculate the percentage that each chemicals treatment suppresses mycelial growth, the EC of each medicament is obtained in linear regression analysis between the probit value by inhibiting rate and the logarithm value of serial drug concentration
50, according to the interaction that the method for Wadley is calculated mixed agent, A, B represent two medicament components respectively, and a|, b are the ratios of each component content in mixture.Analyze the effect be mixed with the SR value.Wherein: SR=0.5～1.5, two kinds of medicaments addition that has been mixed then, SR≤0.5, two kinds of medicaments antagonism that has been mixed then, SR 〉=1.5, then two kinds of medicaments synergistic effect that has been mixed.
The computational methods of SR value are:

SR 〉=1.5, showing after both are mixed has obvious synergistic effect
2, chlorine nalidixic bacterium ester mixes the effect to black shank with Metalaxyl-M.
The mycelial growth rate method is adopted in test.The previously prepared inoculated by hypha block of picking is on the EPA of different drug concentrations culture medium flat plate, cultivated 6 days down at 22 ℃, check colony diameter, calculate the percentage that each chemicals treatment suppresses mycelial growth, the EC of each medicament is obtained in linear regression analysis between the probit value by inhibiting rate and the logarithm value of serial drug concentration
50, the interaction of calculating mixed agent according to the method for Wadley.
The composite control black shank of chlorine nalidixic bacterium ester and Metalaxyl-M result of the test gathers:
