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

Benzylpyrimidine\u00b7Benzothiazole 53% Wettable Powder is aBinary Formulation Herbicide Specifically Designed for Rice Fields<\/strong>, bySulfonylurea systemic herbicide (benzothiadiazole)<\/strong>andAmide-type mitosis inhibitors (benzothioxyl-2,4-dichlorophenoxyacetic acid)<\/strong>Scientifically formulated. This product isSingle-application herbicide<\/strong>...It provides excellent control of most annual weeds and some perennial weeds in rice fields, combining both \u201dpre-emergence and systemic\u201d modes of action, making it a highly effective solution for integrated weed management in transplanted, direct-seeded, and broadcast-seeded rice fields.<\/p>\n

The Principle of Synergy<\/strong><\/h4>\n
    \n
  1. \n
    \n

    Broadleaf Cyperus Herbicide (Benzylsulfuron):<\/strong> Once absorbed by the roots and leaves of weeds, it is transported to various parts of the plant, inhibiting the biosynthesis of branched-chain amino acids (such as isoleucine) and preventing cell division and growth. It is highly effective against duckweed, water caltrop, water parsnip, and sedge weeds (such as water hairgrass, heteromorphic sedge, and water sedge).<\/p>\n

    <\/div>\n<\/div>\n<\/li>\n
  2. \n
    Grass-Species Pre-emergence (Bentazone):<\/strong> It is absorbed by young weed shoots, inhibits cell division, and disrupts the synthesis of very-long-chain fatty acids, causing the young shoots to die from poisoning before they emerge from the soil. It is highly effective against grass weeds such as barnyard grass and goosegrass.<\/div>\n<\/li>\n
  3. \n
    Synergy:<\/strong> Benzylsulfuron compensates for the poor efficacy of benzothiadiazoxyl against broadleaf weeds and sedge weeds; Benzothiadiazoxam compensates for benzosulfuron\u2019s poor efficacy against barnyard grass, thereby achieving complete control of grass, broadleaf, and sedge weeds in rice fields.<\/div>\n<\/li>\n<\/ol>\n

    1. Seize the opportunity<\/strong><\/td>\nFor direct-seeding fields, apply the pesticide after the rice seedlings have taken root and become well-established; for transplanted fields, apply the pesticide 5\u20137 days after transplanting; for direct-seeding fields, apply the pesticide when the seedlings are at the two-leaf-one-heart stage.<\/td>\n<\/tr>\n
    2. Weed Leaf Stage<\/strong><\/td>\nPesticides are most effective when applied before the two-leaf stage of barnyard grass; the younger the weed, the better.<\/td>\n<\/tr>\n
    3. Aquifer Management<\/strong><\/td>\nBefore application, maintain a water depth of 3\u20134 centimeters in the field; after application, maintain the water level for 5\u20137 days, taking care not to submerge the rice plant\u2019s terminal leaf.<\/td>\n<\/tr>\n
    4. Preparation of Toxic Soil<\/strong><\/td>\nFirst, mix this product thoroughly with a small amount of moist fine soil (sand), then blend it evenly with the remaining moist fine soil (sand) or chemical fertilizer, and apply it evenly.<\/td>\n<\/tr>\n
    5. Apply the pesticide evenly<\/strong><\/td>\nEnsure that the pesticide is evenly distributed over the field to avoid over-spraying or missed spots.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

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

      \u23f0 Grasp the application window:<\/strong> In fields where rice seedlings are transplanted, the seedlings must beAfter the sapling has taken root<\/strong>Applying pesticides before the plants have taken root can easily cause phytotoxicity; in direct-seeding fields,Seedlings at the 2-leaf-and-1-heart stage<\/strong>Applying the pesticide too early can cause phytotoxicity.<\/p>\n

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

      \ud83d\udca7 Water Management:<\/strong> Maintain the following during and after application:3\u20135 cm water depth, 5\u20137 days<\/strong>, The water level should not submerge the rice plant\u2019s terminal leaf; this method is less effective on sandy soils and in fields with poor drainage.<\/p>\n

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

      \ud83c\udf31 Age of barnyard grass:<\/strong> Use the upper limit of the recommended dose when barnyard grass is at an advanced growth stage, and the lower limit when it is at an early growth stage; efficacy decreases when barnyard grass has more than three leaves.<\/p>\n

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

      \ud83d\udeab Contraindications:<\/strong> This product is ineffective on sandy soils and waterlogged fields and is not recommended for use in such conditions; late-season rice varieties (japonica and glutinous rice) are relatively sensitive, so application during the budding stage of late-season rice should be avoided as much as possible.<\/p>\n
