I. Mechanism of Action of the Active Ingredients<\/h3>\n
Dichlorvos belongs toOrganophosphate insecticides of the thiophosphate class<\/strong>, whose primary target is the insect nervous system'sAcetylcholinesterase (AChE)<\/strong>\u3002<\/div>\n
Mechanism of Action:<\/strong>
\nOnce chlorpyrifos enters the pest\u2019s body, it undergoes bioactivation to form a more toxic oxon derivative (chlorpyrifos oxon), which forms a stable covalent bond with the active site of acetylcholinesterase, irreversibly inhibiting enzyme activity. This leads to a massive accumulation of acetylcholine (ACh) in the synaptic cleft, which continuously stimulates the postsynaptic membrane, causing the nerve fibers to remain in a state of prolonged hyperexcitability. After poisoning, the pests exhibit abnormal excitement, convulsions, and paralysis, ultimately leading to death.<\/div>\n
This mode of action is effective against both chewing and sucking pests, and is unlikely to result in cross-resistance with pyrethroids.<\/div>\n

IV. Processing and Usage Guidelines<\/h3>\n
Precautions for Pharmaceutical Manufacturing<\/strong><\/div>\n
    \n
  • \n
    Solvent Selection:<\/strong> For the formulation of emulsifiable concentrates and microemulsions, it is recommended to blend aromatic solvents (such as xylene and solvent oil) with polar solvents to improve the dissolution stability of the active ingredient.<\/div>\n<\/li>\n
  • \n
    Emulsion System:<\/strong> For microemulsions, it is recommended to use a combination of nonionic and anionic emulsifiers to ensure that the transparency temperature range covers the climatic conditions of the target market.<\/div>\n<\/li>\n
  • \n
    pH Control:<\/strong> The pH of the processed product and the finished product is strictly controlled between 4.0 and 7.0; under alkaline conditions, chlorpyrifos is prone to hydrolysis and loss of efficacy.<\/div>\n<\/li>\n
  • \n
    Sustained-release packaging materials:<\/strong> For microcapsule suspensions, it is recommended to use polyurethane or urea-formaldehyde resin as the wall material, with a controlled release rate of 7\u201321 days.<\/div>\n<\/li>\n<\/ul>\n
    mixing taboo<\/strong><\/div>\n
      \n
    • \n
      Do not mix with alkaline substances under any circumstances.<\/strong>(such as Bordeaux mixture, lime-sulfur solution, and alkaline fillers), which are prone to decomposition and loss of effectiveness under alkaline conditions<\/div>\n<\/li>\n
    • \n
      It is corrosive to brass; therefore, it is recommended to use stainless steel for parts that come into contact with processing equipment.<\/div>\n<\/li>\n<\/ul>\n
      Sensitive Crops Alert<\/strong><\/div>\n
        \n
      • \n
        Tobacco, lettuce, melon seedlings, tomatoes<\/strong>Since these crops are sensitive to chlorpyrifos, downstream formulations should not be recommended for foliar spraying on the aforementioned crops.<\/div>\n<\/li>\n
      • \n
        Use ornamental plants such as azaleas, roses, and camellias with caution<\/div>\n<\/li>\n<\/ul>\n
        Environmental and Ecological Security<\/strong><\/div>\n
          \n
        • \n
          Highly toxic to fish and aquatic organisms; the label on the downstream formulation should state: \u201dDo not use near aquaculture areas, rivers, ponds, or other bodies of water.\u201d<\/div>\n<\/li>\n
        • \n
          Highly toxic to bees; do not use during the flowering period of flowering crops.<\/div>\n<\/li>\n
        • \n
          Toxic to silkworms; do not use near mulberry groves<\/div>\n<\/li>\n<\/ul>\n
          Storage and Transportation<\/strong><\/div>\n
            \n
          • \n
            Store in a cool, dry, well-ventilated warehouse, away from sources of fire and heat, and avoid direct sunlight.<\/div>\n<\/li>\n
          • \n
            Store separately from oxidizing agents, alkalis, and food-grade chemicals; never store them together.<\/div>\n<\/li>\n
          • \n
            Protect from rain and moisture during transport; handle with care to prevent damage to the packaging.<\/div>\n<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"
