Example

[0034] The embodiment of the present invention adopts a method combining indoor toxicity determination and field test. Application Example 1: Indoor virulence determination of pyraclostrobin and propamocarb or its salt (or Bentianil) against cucumber downy mildew

[0035] After pre-testing to determine the effective inhibitory concentration range of each medicament, each medicament was treated with 5 doses according to the content of the active ingredient, and a clear water control was set. Refer to the "Pesticide Indoor Bioassay Test Guidelines for Fungicides", and use the mycelial growth rate method to determine the virulence of the agent to cucumber downy mildew. After 72 hours, the colony diameter was measured by the cross method, and the net growth amount and mycelial growth inhibition rate of each treatment were calculated.

[0036] Net growth (mm) = measured colony diameter -5

[0037]

[0038] The mycelial growth inhibition rate is converted into a probability value (y), th...

Abstract

The invention relates to a sterilization composition containing pyraclostrobin and carbamates, which comprises effective active components of pyraclostrobin (A) and one (B) selected from diethofencarb, propamocarb or salts thereof, or isopropyl, wherein the weight ratio of A to B is 60:1-1:60. Assistants and excipients are added into the effective active components so that the effective active components are prepared into water dispersible granules, a suspending agent and the like. The sterilization composition is mainly used for controlling downy mildew, pestilence, gray mold, powdery mildew, anthracnose, leaf spot, cladosporium cucumerinum and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the preparation and application of a fungicidal composition containing pyraclostrobin and carbamates. technical background [0002] Pyraclostrobin (pyraclostrobin), molecular formula: C 20 h 23 N 3 o 2 , Chemical name: Methyl (N)-[[[1-(4-chlorophenyl)pyrazol-3yl)-oxygen]-O-methoxy]-N-methoxycarbamate. [0003] Pyraclostrobin is the latest methoxyacrylate fungicide of BASF. The pure product is white to light beige odorless crystals. The mechanism of action is a mitochondrial respiration inhibitor. Mitochondria cannot produce and provide the energy required for normal cell metabolism, eventually leading to cell death. It can control most diseases such as Ascomycetes, Basidiomycetes, Deuteromycetes and Oomycetes. It has a strong inhibitory effect on spore germination and the growth of mycelium in leaves, and has protective and therapeutic activities. Possesses permeability...
