Abstract
The invention discloses a bactericidal composition of clorine-nalidixic-methyl and Propamocarb, which is characterized in that: the medical ingredients of the composition consist of the clorine-nalidixic-methyl and the Propamocarb. The composition has good and obvious bactericidal effect in preventing and treating crop diseases such as powdery mildew, banded sclerotial blight, stripe rust, root rot, rice blast, large and small leaf spot of corns, downy mildew, gray mold and sclerotinia, etc.
Description
Technical field:
The present invention relates to a kind of agricultural chemicals.
Background technology:
There is undesirable part in existing agricultural chemicals at aspects such as control crop powdery mildew, banded sclerotial blight, yellow rust, root rot, rice blast, corn northern and southern leaf blight, downy mildew, gray mold, stalk breaks.
Summary of the invention:
The object of the present invention is to provide the good chlorine nalidixic bacterium ester of a kind of bactericidal effect, Propamocarb bactericidal composition and purposes.
Technical solution of the present invention is:
A kind of chlorine nalidixic bacterium ester, Propamocarb bactericidal composition is characterized in that: its drug ingedient is made up of chlorine nalidixic bacterium ester, Propamocarb.
The weight ratio of chlorine nalidixic bacterium ester, Propamocarb is 1～50: 1～60.
A kind of chlorine nalidixic bacterium ester, the application of Propamocarb bactericidal composition in preparation control crop powdery mildew, banded sclerotial blight, yellow rust, root rot, rice blast, corn northern and southern leaf blight, downy mildew, gray mold, stalk break medicine.
Product of the present invention confirms that through test bactericidal effect is good, particularly at aspects such as control crop powdery mildew, banded sclerotial blight, yellow rust, root rot, rice blast, corn northern and southern leaf blight, downy mildew, gray mold, stalk breaks, has significant effect.
Concrete Test Example:
1, the composite effect of chlorine nalidixic bacterium ester and Propamocarb to capsicum epidemic disease
The capsicum epidemic disease mycelia piece that picking prepares in advance is inoculated on the EPA culture medium flat plate of different drug concentrations; Mycelia faces up; Cultivated 5 days down at 22 ℃, the inspection colony diameter calculates the percentage that each chemicals treatment suppresses mycelial growth; The EC of each medicament is obtained in linear regression analysis between the probit value through 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:
EC
50(theoretical value)=(a+b)/(a/EC
50a+ b/EC
50b)
SR=EC
50(theoretical value)/EC
50(real value)
The composite control capsicum epidemic disease of chlorine nalidixic bacterium ester and Propamocarb result of the test gathers:
| Medicament | EC 50μ g/ml (theoretical value) | EC 50μ g/ml (observed value) | SR 50 |
| Chlorine nalidixic bacterium ester | 0.3547 | ||
| Propamocarb | 0.5679 | ||
| Chlorine nalidixic bacterium ester, Propamocarb 4: 1 | 0.3835 | 0.2397 | 1.6 |
| Chlorine nalidixic bacterium ester, Propamocarb 2: 1 | 0.4054 | 0.1501 | 2.7 |
| Chlorine nalidixic bacterium ester, Propamocarb 1: 1 | 0.4367 | 0.1065 | 4.1 |
| Chlorine nalidixic bacterium ester, Propamocarb 1: 2 | 0.4731 | 0.1928 | 4.6 |
| Chlorine nalidixic bacterium ester, Propamocarb 1: 4 | 0.5069 | 0.1584 | 3.2 |
SR >=1.5, showing after both are mixed has obvious synergistic effect.
2, chlorine nalidixic bacterium ester and the composite effect of white urea cyanogen to soybean blight
The soybean blight inoculated by hypha block that picking prepares in advance is on the culture medium flat plate of different drug concentrations; Mycelia faces up; Cultivated 8 days down at 22 ℃, the inspection colony diameter calculates the percentage that each chemicals treatment suppresses mycelial growth; The EC of each medicament is obtained in linear regression analysis between the probit value through inhibiting rate and the logarithm value of serial drug concentration
50, the interaction of calculating mixed agent according to the method for Wadley.
Chlorine nalidixic bacterium ester and the composite control soybean blight of white urea cyanogen result of the test gather:
| Medicament | EC 50μ g/ml (theoretical value) | EC 50μ g/ml (observed value) | SR 50 |
| Chlorine nalidixic bacterium ester | 1.2108 | ||
| Frost urea cyanogen | 3.7850 | ||
| Chlorine nalidixic bacterium ester, white urea cyanogen 2: 1 | 1.5657 | 0.5799 | 2.7 |
| Chlorine nalidixic bacterium ester, white urea cyanogen 1: 1 | 1.8348 | 0.5242 | 3.5 |
| Chlorine nalidixic bacterium ester, white urea cyanogen 1: 2 | 2.2153 | 0.7639 | 2.9 |
SR >=1.5, showing after both are mixed has obvious synergistic effect.
Below in conjunction with embodiment the present invention is described further.
