I. Product Profile<\/h3>\n
Pyrim\u00b7Propachlor 35% Wettable Powder is aBinary Formulation Herbicide Specifically Designed for Rice Fields<\/strong>, bySulfonylurea Herbicide for Broadleaf Cyperus (Pyrimidylsulfuron)<\/strong>andAmide-type mitosis inhibitors (propachlor)<\/strong>Scientifically formulated. This product combines the dual effects of \u201dsurface-acting and systemic\u201d action, providing excellent control of annual grass weeds, broadleaf weeds, and sedge weeds in direct-seeded rice fields. It is a highly effective solution for the integrated weed management of direct-seeded rice fields.<\/p>\n

The Principle of Synergy<\/strong><\/h4>\n
    \n
  1. \n
    Broadleaf Cyperus Herbicide (Pyrimidylsulfuron):<\/strong> It is primarily absorbed through the root system, rapidly translocates within the weed plant, inhibits ALS enzyme activity, and blocks the synthesis of branched-chain amino acids, causing the weed to gradually die. It provides excellent control against annual and perennial broadleaf weeds and Cyperaceae weeds, including common sedge, water sedge, water arrowhead, duckweed, water celery, water purslane, wild arrowhead, water milfoil, duckweed, and water hyssop.<\/p>\n
    <\/div>\n<\/div>\n<\/li>\n
  2. \n
    Grass Weed Control (Propachlor):<\/strong> Weed seeds absorb the herbicide during germination; however, absorption through the roots is poor, so it can only be applied as a pre-emergence soil treatment. It inhibits cell division and interferes with the synthesis of very-long-chain fatty acids, causing young weed seedlings to die from poisoning before they emerge from the soil. It is highly effective against barnyard grass.<\/p>\n
    <\/div>\n<\/div>\n<\/li>\n
  3. \n
    Synergy:<\/strong> Pyrimidylsulfuron compensates for propachlor\u2019s poor efficacy against broadleaf weeds and sedge weeds; Propanil compensates for pyrimidylsulfuron\u2019s limited effectiveness against barnyard grass and duckweed, thereby achieving complete control of grass, broadleaf, and sedge weeds in direct-seeded rice fields.<\/div>\n<\/li>\n<\/ol>\n

    1. Seize the opportunity<\/strong><\/td>\nApply the herbicide during the 1\u20133-leaf stage of rice or from sowing until the weeds reach the 2-leaf stage; the best results are achieved during the early stages of weed emergence.<\/td>\n<\/tr>\n
    2. Aquifer management<\/strong><\/td>\nMaintain a water depth of 3\u20135 cm during application, and keep the field flooded for 3\u20135 days (direct-seeding fields) or 5\u20137 days (transplanted fields) after application.<\/td>\n<\/tr>\n
    3. Dispensing methods<\/strong><\/td>\nUsing the two-step dilution method, first thoroughly disperse the chemical in a small amount of water, then add sufficient water.<\/td>\n<\/tr>\n
    4. Poisonous soil method<\/strong><\/td>\nMix the formulation with 20 kilograms of fine, moist soil per mu, and apply evenly after the morning dew has dried.<\/td>\n<\/tr>\n

    \u26a0\ufe0f\u00a0Key Considerations<\/strong><\/h4>\n
      \n
    1. \n
      \u23f0 Optimal application period:<\/strong> maize1\u20133-leaf stage<\/strong>Or from sowing until weeds appearUp to the two-leaf stage<\/strong>For best results, apply the pesticide; in dry-seeded fields, flood-irrigate once 1\u20132 days after application and keep the soil moist.<\/p>\n
      <\/div>\n<\/div>\n<\/li>\n
    2. \n
      \ud83d\udeab Contraindications:<\/strong> \u5bf9Qianjinzi is ineffective<\/strong>...Fields where \"Qianjinzi\" is the primary crop should be treated with a mixture of this product and other herbicides; as it is relatively sensitive to late-season rice varieties (japonica and glutinous rice), application during the tillering stage of late-season rice should be avoided whenever possible.<\/p>\n
      <\/div>\n<\/div>\n<\/li>\n
    3. \n
      \ud83d\udca7 Water Management:<\/strong> Maintain a water depth of 3\u20135 cm during application, and keep the field watered for 3\u20135 days after application. For dry-seeded fields, flood-irrigate once 1\u20132 days after application and keep the soil moist.<\/p>\n
      <\/div>\n<\/div>\n<\/li>\n
    4. \n
      \ud83c\udf21\ufe0f Temperature effects:<\/strong> The drug's efficacy is stable and is minimally affected by temperature.<\/div>\n<\/li>\n
    5. \n
      \ud83d\udc1f Aquatic safety:<\/strong> It is low in toxicity to fish, birds, and bees, but caution is still advised in rice paddies where fish are raised.<\/div>\n<\/li>\n
    6. \n
      \ud83e\uddea Blending recommendations:<\/strong> When used alone, it is very ineffective against barnyard grass at the two-leaf stage or later; it is often combined withHecaote or dichloroquinoline acid<\/strong>When used in combination, they provide excellent protection.<\/p>\n
      <\/div>\n<\/div>\n<\/li>\n
    7. \n
      \ud83d\udd04 Resistance management:<\/strong> Long-term single use is prone to resistance, it is recommended to combine withBenzylsulfuron, Pentafluorophenoxanil<\/strong>Rotate the use of herbicides with different modes of action.<\/div>\n<\/li>\n
    8. \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
    9. \n
      \ud83e\uddf9 Instrument cleaning:<\/strong> Thoroughly clean the sprayer after use to prevent residual pesticide from causing phytotoxicity to other crops.<\/div>\n<\/li>\n
    10. \n
      \ud83d\udce6 Storage conditions:<\/strong> Store in a cool, dry, well-ventilated place, away from direct sunlight and high temperatures; keep away from sources of fire and out of the reach of children.<\/div>\n<\/li>\n<\/ol>\n
