Abstract
The invention discloses bactericide for preventing and treating brown blotch of corns. The bactericide comprises fastigilin C and cucurbitacine A, wherein the weight part ratio of the fastigilin C to the cucurbitacine A is (1:1) to (25:1). The bactericide has a good effect of synergistically preventing and treating the brown blotch of the corns under the compatibility of the fastigilin C and the cucurbitacine A and according to a specific proportion.
Description
Technical field
The present invention relates to a kind of medicament, specifically a kind of bactericide of preventing and treating maize brown spot, belong to agricultural technology field.
Background technology
In agricultural production practice, bacterial diseases of plants and fungal disease usually mix generation.Chemical prevention is to subtract
Hypopathia evil loss, the important channel boosted agricultural yield.Some bactericidal agent for preventing and treating spectrums are narrower, and the agent of peasant's necessary various sterilization is together
Use.But, long-term, applied chemistry bactericide in large quantities, it can be developed immunity to drugs for germ so that preventive effect declines rapidly, must not
Consumption is not increased.The abuse of chemical bactericide result in serious environmental pollution and food-safety problem.Novel biological bactericide
Exploitation be the important method for cracking above-mentioned dilemma.
People is there is no to report at present with the bactericidal composition preventing and treating maize brown spot of the compounding of cucurbitacin A with regard to fastigilin C
Road mistake.
The content of the invention
For the problem that above-mentioned prior art is present, it is an object of the invention to provide the sterilization containing fastigilin C
Composition, it is to be compounded the sterilization component of two kinds of different structures, the different mechanisms of action, is expanding prevention spectrum and raising
The effective way of drug effect, it is often more important that avoid or delay generation of the disease to new composition resistance.To realize the purpose of the present invention,
Inventor coordinates fastigilin C and cucurbitacin A, for preventing and treating the disease of crop.
To achieve these goals, the technical solution used in the present invention is：A kind of bactericide bag of preventing and treating maize brown spot
Containing two kinds of principle active components：Fastigilin C（CAS accession number 6995-12-6）With cucurbitacin A（CAS accession number 6040-19-
3）.
Described fastigilin C is with the ratio of the parts by weight of cucurbitacin A, 25:1-1:1.
Active ingredient accounts for the 1%～90% of gross weight..
Said composition can be made into suspending agent, wettable powder, seed coat agent, aqueous emulsion, microemulsion, missible oil, granule, moisture
Shot agent.
The present invention under specific ratio by fastigilin C and cucurbitacin A compatibilities by having found there is collaboration well
The effect of preventing and treating maize brown spot, the particularly ratio in fastigilin C and the parts by weight of cucurbitacin A are 10:1-13:1 it
Between, its collaboration preventing and treating maize brown spot effect is apparent, and whole reagent cost is relatively low, and toxicity is less.
Specific embodiment
Fastigilin C（CAS accession number 6995-12-6）With cucurbitacin A（CAS accession number 6040-19-3）Market has
Sale.
Embodiment 1
Fastigilin C is with the ratio of the parts by weight of cucurbitacin A, 20:1,
The weight sum of described fastigilin C and cucurbitacin A account for the 9% of the medicament gross weight, % of organic silicon defoamer 0.2, ten
The % of dialkyl benzene sulfonic acids calcium 8, the % of xanthans 0.1, ethylene glycol 5%, deionized water supply 100%.

Laboratory test：
First, indoor biometricses test
Mycelial growth rate method is adopted indoors, determines EC50 value of the different agents to bacterial strain, by co-toxicity coefficient computational methods,
The co-toxicity coefficient (CTC) of mixture is calculated, the building performance of mixture is determined, circular is as follows：
A certain single dose (generally selects EC50 juniors) as standard agent with mixture, is calculated：
Single dose toxicity index=standard agent EC50/ single dose EC50 × 100
The toxicity index of the toxicity index of theoretical toxicity index TTI=A single dose × A single doses proportion+B single doses in mixture
× B single doses proportion in mixture
EC50 value × 100 of the EC50 values/mixture of actual measurement toxicity index ATI=standard single dose
Co-toxicity coefficient=actual measurement toxicity index/theoretical toxicity index × 100
Co-toxicity coefficient is classified：Mixture has synergetic when CTC is more than 120, is antagonism when CTC is less than 80, and CTC is in 80-
It is summation action between 120.
Fastigilin C：Indoor biometricses result of the cucurbitacin A different ratios to maize brown spot bacterium.
| Reagent treatment | Co-toxicity coefficient CTC | Prevention effect % |
| Fastigilin C：Cucurbitacin A（20：1） | 101.2 | 55 |
| Fastigilin C：Cucurbitacin A（15:1） | 94.1 | 52 |
| Fastigilin C：Cucurbitacin A（13:1） | 184.1 | 90 |
| Fastigilin C：Cucurbitacin A（10:1） | 224.3 | 95 |
| Fastigilin C：Cucurbitacin A（5:1） | 102.3 | 48 |
| Fastigilin C：Cucurbitacin A（3:1） | 87.6 | 44 |
| Fastigilin C：Cucurbitacin A（1:1） | 96.3 | 46 |
| Fastigilin C：Cucurbitacin A（1:6） | 91.3 | 33 |
From the measurement result of table, as fastigilin C：Cucurbitacin A proportionings are 10:1-13:It is brown for corn when between 1
Pinta bacterium co-toxicity coefficient is both significantly higher than 150, and with obvious synergistic effect, and other ratios mix, and co-toxicity coefficient is failed to understand
It is aobvious.And its prevention effect is also much higher than other groups.
