Description
Technical field
The present invention relates to a kind of disinfectant use in agriculture, body ground processed says to be a kind of containing in Metalaxyl-M, propamocarb and hundred
The water preparation formulations containing same, and uses therefor of fragrant phenol.
Technical background
Metalaxyl-M belongs to acid amide fungicides, has protection and therapeutical effect, can be absorbed by the root, stem and leaf of plant, and with
Object in Water Transportation, and transfer to each organ of plant.To Pseudoperonospora cubensis, phytophthora pathogenic bacteria, the vegetable caused by rotten mildew fungus,
Fruit tree, Nicotiana tabacum L., oil plant, Cotton Gossypii, the crop pest such as grain has more excellent preventive effect.
Propamocarb belongs to carbamate fungicide, safe and efficient, has specially good effect to Oomycete fungal, main suppression
The phospholipid of pathogenic bacteria cell membrane component processed and the biosynthesiss of fatty acid, suppression mycelial growth, sporangial formation and sprouting.Interior suction
Conductivity is good, when being used as soil treatment, can be quickly by root absorption and be conveyed upwards into whole plant；When being used as cauline leaf process, energy
Absorbed by blade quickly and be distributed in blade.To crop safety, there is obvious promotion growth to the root of crop, stem, leaf simultaneously
Effect.
Thymol is a separation and Extraction class plant source active component out from Chinese herbal medicine Herba thymi vulgariss, in natural environment
In easily degrade, to person poultry safety, environmental protection, have certain fragrance and there are parasite killing, sterilization, antisepsises.As potentiation
Agent, thymol works in coordination with collocation potentiation substantially with Metalaxyl-M, propamocarb, significantly improves bactericidal effect.
Find domestic patent CN201210350050.3 at present and disclose a kind of " Propamocarb and metalaxyl or Metalaxyl-M water
The preparation method of agent ".Although preparation is water preparation dosage form, still need to use methanol, second according to the process that patent description possesses
The organic solvents such as alcohol, isopropanol, the potential risks such as thus have pollution environment, are detrimental to health.
Instant invention overcomes Metalaxyl-M is compounded by above shortcoming with propamocarb is prepared into water preparation, without first
The organic solvents such as alcohol, ethanol, isopropanol, pure water works as dissolving medium, cost is relatively low, good drug efficacy, processing and use during right
The mankind and Environmental security.Metalaxyl-M is compounded with propamocarb, realizes the synergism of different sterilization mechanisms, expands anti-
Control spectrum.The bactericidal effect of preparation can significantly be lifted simultaneously with vegetable-derived components thymol for synergist, and can have
Effect delays the drug-fast generation of pathogenic bacteria, promotes the growth of crop very well.
