\n
\n\n\n\n\n\n\n
active ingredient<\/th>\nFunction Category<\/th>\nTargets and Mechanisms of Action<\/th>\n<\/tr>\n<\/thead>\n
Cypermethrin<\/strong><\/td>\nType II pyrethroids<\/td>\nActs on insect neuronsVoltage-gated sodium channels<\/strong>...delays the closure of sodium channels, causing sustained depolarization of nerve cells, which leads to hyperexcitability, convulsions, paralysis, and death; it has potent contact and stomach toxicity, as well as a rapid knockdown effect<\/td>\n<\/tr>\n
chlorpyrifos (chlorpyrifos)<\/strong><\/td>\norganophosphorus<\/td>\nInhibitionAcetylcholinesterase (AChE)<\/strong>... by inhibiting the hydrolysis of the neurotransmitter acetylcholine, causing acetylcholine to accumulate in the synaptic cleft and continuously stimulating cholinergic neurons, leading to respiratory failure and death in pests; it has a triple action: contact, stomach, and fumigant effects<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n
Coordination Mechanism<\/strong>: Cypermethrin provides rapid knockdown and repellent effects, while fipronil offers deep systemic penetration and sustained control; when mixed, the two significantly broaden the spectrum of insecticidal activity and help overcome resistance to single-ingredient formulations.<\/div>\n

    Extremely broad spectrum of insecticidal activity<\/strong>: Highly effective against Lepidoptera (cotton bollworm, cabbage looper), Coleoptera (soil-dwelling pests), and Homoptera (aphids, planthoppers)<\/div>\n<\/li>\n
  • \n
    Highly permeable<\/strong>: Emulsifiable concentrates spread well on plant surfaces, penetrate the cuticle of leaves, and are effective against hidden pests.<\/div>\n<\/li>\n
  • \n

  • \n
    Moderate shelf life<\/strong>: Remains effective in the soil for 14\u201321 days and on plant surfaces for 7\u201310 days, combining both fast-acting and long-lasting effects<\/div>\n<\/li>\n
  • \n
    Antibiotic Resistance Management<\/strong>: A combination of two different modes of action effectively delays the development of resistance, making it suitable for use in areas with resistant pests.<\/div>\n<\/li>\n<\/ul>\n

    Method of application<\/strong>: Apply a uniform spray during the early life stages of pests. To control soil-dwelling pests, dilute the pesticide solution with water and apply it by digging trenches to drench the roots, or spray the soil before sowing.<\/div>\n
    \n

    V. Guidance for use<\/h2>\n

    \u2705 Best Time to Apply Pesticides<\/h3>\n
      \n
    • \n
      cotton bollworm<\/strong>: Apply the pesticide during the peak egg-hatching period through the 1st\u20133rd instar larval stage, focusing on spraying the tender leaves at the tops of cotton plants, buds, bolls, and the tips of plant clusters.<\/div>\n<\/li>\n
    • \n
      Soil Pests<\/strong>: Apply the pesticide before sowing or during the seedling stage; for soil treatment, ensure even coverage of the pesticide in a 10\u201315 cm layer of soil.<\/div>\n<\/li>\n
    • \n
      Aphids<\/strong>: Apply the pesticide during the spot-forming stage or before leaf curling, taking care to spray the undersides of the leaves.<\/div>\n<\/li>\n<\/ul>\n

      \u2705 Mixing Pesticides and Spraying<\/h3>\n
        \n
      • \n
        secondary dilution<\/strong>: First, prepare a stock solution using a small amount of water, then add a sufficient amount of water (30\u201350 L per mu; double the amount of water for soil treatment).<\/div>\n<\/li>\n
      • \n
        Soil Treatment<\/strong>: To control soil-dwelling pests, mix the pesticide thoroughly with 20\u201330 kg of fine soil, spread the mixture over the soil, and then lightly cultivate the soil to incorporate it.<\/div>\n<\/li>\n
      • \n
        Precautions for Mixing<\/strong>: Can be mixed with most acidic and neutral pesticides, but avoid mixing with alkaline substances (Bordeaux mixture, lime-sulfur mixture)<\/div>\n<\/li>\n<\/ul>\n

        \u26a0\ufe0f Notes<\/h3>\n
          \n
        1. \n
          safety interval<\/strong>: Cotton\u201421 days; rice\u201421 days; vegetables\u201410 days; fruit trees\u201421 days<\/div>\n<\/li>\n
        2. \n
          Highly Toxic Aquatic Organisms<\/strong>: Extremely toxic to fish, shrimp, and crabs; use is strictly prohibited in aquaculture areas and rice paddies where fish and shrimp are raised; after application, water from the field must not be discharged into fish ponds.<\/div>\n<\/li>\n
        3. \n
          Highly Toxic to Bees<\/strong>: Do not use on flowering crops during the flowering period; relocate beehives or avoid the nectar flow period before application.<\/div>\n<\/li>\n
        4. \n
          Toxicity Warning<\/strong>: Chlorpyrifos is a moderately toxic organophosphate; operators must take strict protective measures to avoid skin contact and inhalation.<\/div>\n<\/li>\n
        5. \n
          Resistance management<\/strong>: Use no more than twice per growing season; it is recommended to rotate with biological or newer-generation pesticides such as Bacillus thuringiensis (Bt) and chlorantraniliprole.<\/div>\n<\/li>\n
        6. \n
          Crop Sensitivity<\/strong>: Some cucurbit crops (cucumbers, watermelons) may be sensitive to emulsifiable concentrates during the seedling stage; it is recommended to reduce the concentration or avoid application during the seedling stage.<\/div>\n<\/li>\n
        7. \n
          Detox Preparation<\/strong>: Organophosphate poisoning can be treated with atropine and pralidoxime; first-aid supplies must be available at the application site.<\/div>\n<\/li>\n<\/ol>","protected":false},"excerpt":{"rendered":"
