selectivity principle (physics)<\/strong><\/h4>\n
    \n
  • \n
    Rice has a natural resistance to dichloroquinoline acid, and the pesticide is rapidly metabolized and broken down within the plant.<\/div>\n<\/li>\n
  • \n
    Barnyard grass is highly sensitive to dichloroquinoline acid; accumulation of the herbicide leads to necrosis of the growing point.<\/div>\n<\/li>\n
  • \n
    \n

    Highly selective, with a wide application window; a single application can control barnyard grass throughout the entire rice growing season.<\/p>\n

    \u26a0\ufe0f\u00a0Key Considerations<\/strong><\/h4>\n
      \n
    1. \n
      \n

      \u23f0 Optimal application period:<\/strong> Weeds2\u20133-leaf stage<\/strong>This product is most effective when applied at this stage; it controls barnyard grass at the 1\u20137-leaf stage, but the application rate should be increased appropriately as the weeds grow older.<\/p>\n

      <\/div>\n<\/div>\n<\/li>\n
    2. \n
      \n

      \ud83d\udeab Taboos in Rice Paddy Fields:<\/strong> It is essential to use seedbedsApply the pesticide after the two-leaf-one-heart stage<\/strong>, which can cause phytotoxicity if applied too early.<\/p>\n

      <\/div>\n<\/div>\n<\/li>\n
    3. \n
      \n

      \ud83d\udeab Pesticide damage to subsequent crops:<\/strong> High residue levels in the soil can easily cause phytotoxicity in subsequent crops; subsequent crops may include rice, corn, and sorghum, butSolanaceae (tobacco, potatoes, chili peppers, etc.), Apiaceae (carrots, celery), Amaranthaceae (spinach, sugar beet), Malvaceae, Cucurbitaceae (various melons and gourds), Fabaceae, Asteraceae, and Convolvulaceae crops are sensitive to this herbicide.<\/strong>\u3002<\/p>\n

      <\/div>\n<\/div>\n<\/li>\n<\/ol>\n
        \n
      1. \n
        \ud83d\udca7 Water Management:<\/strong> Drain the water the day before application and apply a uniform spray. Irrigate 1\u20132 days after application and maintain a water depth of 3\u20135 centimeters for 5\u20137 days.<\/div>\n<\/li>\n
      2. \n
        \n

        \ud83c\udf21\ufe0f Drift Risk:<\/strong> These crops (carrots, celery, cilantro, etc.) are quite sensitive to the Umbelliferae family; spray drift can easily cause phytotoxicity to these crops in adjacent fields, so spray drift should be avoided during application.<\/p>\n

        <\/div>\n<\/div>\n<\/li>\n
      3. \n
        \n

        \ud83d\udc1f Aquatic safety:<\/strong> This product is non-toxic to fish and bees, but apply it away from aquaculture areas; do not wash application equipment in water bodies.<\/p>\n

        <\/div>\n<\/div>\n<\/li>\n
      4. \n
        \n

        \ud83e\uddea Blending recommendations:<\/strong> can be used withChlorimuron, Benfluralin, Pyrimethanil, Diquat, Cyhalothrin<\/strong>...are used in combination to broaden the spectrum of weeds controlled.<\/p>\n

        <\/div>\n<\/div>\n<\/li>\n
      5. \n
        \n

        \ud83d\udd04 Resistance management:<\/strong> In some areas, dichloroquinoline acid is frequently applied in excess, leading to cumulative pesticide damage in the fields; it is recommended to combine it withPentafluorophenoxanil, Cyanofluorophenoxanil<\/strong>Rotate the use of herbicides with different modes of action, applying them no more than once per season.<\/p>\n

        <\/div>\n<\/div>\n<\/li>\n
      6. \n
        \ud83d\udee1\ufe0f security:<\/strong> Wear protective clothing, gloves, and a mask when applying the pesticide; wash your hands and face immediately after application; pregnant and breastfeeding women should avoid contact.<\/div>\n<\/li>\n
      7. \n
        \ud83d\udce6 Storage conditions:<\/strong> Store in a cool, dry, well-ventilated place, away from direct sunlight and high temperatures; shake the SC formulation well before use.<\/div>\n<\/li>\n<\/ol>\n
