I. Product Profile
异丙甲草胺 720克/升乳油是一种广谱性选择性芽前土壤处理除草剂,属于酰胺类内吸传导型除草剂。本品主要通过杂草幼芽吸收,向上传导,抑制幼芽与根的生长,对一年生禾本科杂草效果优异,兼治部分阔叶杂草。适用于玉米、大豆、花生、棉花、油菜等多种旱地作物,是旱田杂草封闭处理的经典选择。
II. Mechanisms of action of active ingredients
作用靶标:蛋白质合成与细胞膜形成抑制剂
异丙甲草胺属于HRAC Category K3 / WSSA Category 15Herbicides with a mechanism of action:
forms
| active link | Specific mechanisms |
|---|---|
| absorption pathway | 主要通过杂草幼芽基部、胚芽鞘(单子叶)和下胚轴(双子叶)吸收,出苗后主要靠根吸收向上传导 |
| biochemical target | 主要抑制发芽种子的蛋白质合成,其次抑制胆碱渗入磷脂,干扰卵磷脂形成 |
| physiological effect | 阻断细胞膜正常构建,抑制幼芽与根的生长,导致细胞分裂受阻 |
| final performance | 禾本科杂草心叶扭曲、萎缩,阔叶杂草叶子皱缩变黄,整株枯死 |
Characteristics of action
-
土壤湿润时: 杂草被杀死在幼芽期,出土前即中毒死亡
-
土壤干旱时: 杂草出土后随降雨湿度增加,吸收药剂后叶皱缩整株枯死
-
因此施药应在杂草发芽前进行,土壤墒情越好效果越佳

IV. Usage and dosage
📋 Application Guidelines for Major Crops
forms
| Crop type | Application period | Dosage (formulated dose/acre) | water consumption | Mode of application |
|---|---|---|---|---|
| Cornfield | 播种前或播后出苗前 | 100-150 ml/acre | 35-50 kg/mu | Soil spraying |
| Soybean Field | 播种前或播后出苗前 | 100-150 ml/acre | 35-50 kg/mu | Soil spraying |
| Peanut Field | 播种前或播后出苗前 | 125-150毫升/亩 | 35-50 kg/mu | Soil spraying |
| Cotton Field | 播种前或播后出苗前 | 100-150 ml/acre | 35-50 kg/mu | Soil spraying |
| Rapeseed field | 播种前或移栽前 | 100-150 ml/acre | 35-50 kg/mu | Soil spraying |
| Vegetable field | 播种覆土后或定植前 | 80–100 milliliters per mu | 35-50 kg/mu | Soil spraying |
📋 水稻田使用参考
forms
| Crop type | Application period | Dosage (formulated dose/acre) | 水层管理 |
|---|---|---|---|
| Rice transplanting field | 移栽后早稻5-7天、晚稻3-4天 | 10-20毫升/亩 | 灌水2-5cm,保水3-4天 |
| Rice direct seeding field | 催芽播种后2-4天 | 15-25毫升/亩 | 保持湿润,不积水 |
旱地用量说明: 每亩有效成分用量为 72-108克/亩(按100-150毫升/亩计算)。土壤有机质含量高、粘重土壤适当提高用量;砂质土壤、有机质含量低适当降低用量。
V. Guidance for use
🔧 Application Points
forms
| move | operational specification |
|---|---|
| 1. Field preparation | Before applying the pesticide, the soil should be leveled and finely tilled, free of large clumps and weed residues. |
| 2. Soil moisture | 土壤墒情好时直接喷雾;干旱条件下施药后应浅混土或加大兑水量 |
| 3. 覆膜管理 | 覆膜作物田施药后不混土,施药后必须立即覆膜 |
| 4. 配药方法 | 采用二次稀释法,确保乳化均匀 |
| 5. 喷雾质量 | Apply evenly to the soil surface, avoiding over-spraying or missed spots, to ensure a complete soil-pesticide layer is formed. |
⚠️ Key Considerations
-
⏰ Timing of application: This product is a pre-emergent herbicide and must be applied in theBefore weeds emerge施药,对已出土杂草无效。
-
💧 土壤湿度管理: 施药后15天内降15毫米左右雨水,即可保证药效发挥。干旱条件下应加大兑水量或浅混土。
-
🌡️ 温度与土壤影响: 温度偏高时和砂质土壤用药量宜低;气温较低时和粘质土壤用药量可适当偏高。
-
🚫 Sensitive crops: 瓜类、茄果类蔬菜使用浓度偏高时易产生药害,施药时要慎重。
-
🐝 蜜蜂安全: 对蜜蜂有毒,蜜源作物花期禁用;蚕室和桑园附近禁用。
-
🐟 Aquatic safety: 对鱼类有毒,远离水产养殖区施药;禁止在河塘等水体中清洗施药器具。
-
🧪 Mixing Taboo: 不可与呈碱性的农药等物质混合使用。
-
🔄 Resistance management: 建议与其他不同作用机理的除草剂轮换用药,以延缓抗药性产生。每季作物最多使用1次。
-
🛡️ security: 施药时穿戴防护服、手套、口罩、护目镜;施药期间不可吃东西、喝水和吸烟;施药后及时洗手洗脸。
-
