I. Product Profile<\/h3>\n
\n

Propachlor 50% emulsifiable concentrate is aSelective pre-emergence soil-applied herbicides<\/strong>, which belongs to the class of systemic, translaminar amide herbicides. This product is a herbicide specifically formulated for rice fields and is primarily used to control annual grass weeds, sedges, and certain broadleaf weeds in rice fields (direct-seeded, transplanted, and seedling beds). Compared to butachlor, propachlor offers greater safety for rice,Typically used in combination with the safener desmedimide (CGA123407)<\/strong>...ensures the safe use of pesticides from seeding through the seedling stage and is the product of choice for pre-emergence weed control in rice fields.<\/p>\n

Safety Mechanisms in Rice<\/strong><\/h4>\n
    \n
  • \n
    Propachlor, when applied alone, shows poor selectivity against wet-transplanted rice.<\/div>\n<\/li>\n
  • \n
    AddSafety agent CGA123407<\/strong>Afterward, it can activate the detoxification enzyme system within the rice plants, accelerating the metabolism and breakdown of the pesticide.<\/div>\n<\/li>\n
  • \n
    \n

    Therefore, it exhibits excellent selectivity for both transplanted and direct-seeded rice, and its safety profile is significantly superior to that of formulations that do not contain a safety agent.<\/p>\n

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

      \u23f0 Grasp the application window:<\/strong> Must be done byBefore weeds emerge<\/strong>Pesticide application is less effective against weeds that have already emerged. In direct-seeding fields, apply the pesticide within 2\u20134 days after sowing.<\/p>\n

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

      \ud83d\udca7 Water Management:<\/strong> Field Conditions After ApplicationThere must be no standing water<\/strong>... Standing water can increase the rice seedlings' absorption of the pesticide, leading to pesticide damage. Simply keep the soil moist.<\/p>\n

      <\/div>\n<\/div>\n<\/li>\n
    3. \n
      \ud83c\udf31 Seed Requirements:<\/strong> The rice to be sown mustRoots and shoots are normal<\/strong>Seeds that have sprouted but have no roots are sensitive to pesticides and are prone to pesticide damage.<\/div>\n<\/li>\n
    4. \n
      \n

      \ud83c\udf21\ufe0f Regional Differences:<\/strong> When using this product in northern rice-growing regions, the application period should be appropriately extended. Conduct small-scale trials first, followed by large-scale implementation, to prevent phytotoxicity.<\/p>\n

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

      \ud83d\udeab Risk of Excess:<\/strong> Excessive use can cause rice plants to become severely stunted, with the young leaves losing their green color and curling, and a significant reduction in the root system, resulting in severely stunted growth; in severe cases, this can lead to seedling death.<\/p>\n

      <\/div>\n<\/div>\n<\/li>\n
    6. \n
      \ud83e\uddea Safety Agent Requirements:<\/strong> Be sure to useContains the herbicide agent diquat<\/strong>Propanamide formulations\u2014those without safety agents\u2014are less safe for rice.<\/div>\n<\/li>\n
    7. \n
      \ud83d\udd04 Resistance management:<\/strong> It is recommended to rotate this product with herbicides that have different modes of action, such as diquat, oxazolamide, and ethofluoride, and to apply it no more than once per season.<\/div>\n<\/li>\n
    8. \n
      \ud83d\udc1f Aquatic safety:<\/strong> Toxic to fish; do not use in rice paddies where fish are raised; do not wash application equipment in water bodies.<\/div>\n<\/li>\n
    9. \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
    10. \n
      \ud83d\udce6 Storage conditions:<\/strong> Store in a cool, dry place, away from direct sunlight and high temperatures.<\/div>\n<\/li>\n<\/ol>\n
