克芜踪属触杀型天生性除草剂,喷在植物组织的绿色部位即可被迅速吸收。植物组织细胞内的叶绿素在光照下进行光合作用,使细胞内水分蒸发加快,呈现萎黄,进而干枯死亡。光照对药效的影响很大,晴朗天气条件下药效发挥决,喷药2-3小时后杂草立刻枯萎,阴天时则药效缓慢,一般5-6小时后杂草才开始枯萎。但由于杂草有较长时间吸收叶面上的药液,并渗入到组织中,因此杀草更为彻底。 一、应用范围及防除对象 克芜踪破坏绿色植物组织,但不影响植株根部,适用于以下几种情况:①雨季或潮湿地除草,可利用雨隙进行抢种抢播。②蔬菜田行间除草。运用适当的防护配件或配上定向扇型喷嘴,使药液准确洒在作物间杂草上,达到田间除草的最佳效果。③适用于蔬菜播种或移栽前清洁田园。 二、使用方法 用于蔬菜出苗前、杂草早苗期茎叶喷雾或进行苗带保护喷雾。有垅行的作物可采用定向喷雾或保护喷雾。在杂草高度不超过15cm时使用,全面均匀地喷雾,以确保杂草完全与药液接触,可获得最佳的除草效果。 三、注意事项 ①喷雾时要尽量压低喷头,以防雾满飘移到附近作物上产生药害。②克芜踪与草甘磷一样在土壤中无残留,用药后可立即播件或移栽。③该剂耐雨性强,喷药1小时后下雨,不会影响药效。
Ke Wu trace contact is a natural herbicide, spray in the green parts of plant tissues can be quickly absorbed. Plant tissue cells of chlorophyll in the light of photosynthesis, so that the rapid evaporation of water within the cells, showing chlorosis, and then died of death. The effect of light on the efficacy of a large, sunny weather conditions to play the final effect, spray 2-3 hours after the weeds immediately withered, cloudy when the efficacy is slow, generally 5-6 hours after the weeds withered. However, because weeds have a long time to absorb the liquid on the foliage, and penetrate into the tissue, so kill grass more thoroughly. First, the scope of application and control objects Ke Wu trace destruction of green plant tissue, but does not affect the plant roots, apply to the following situations: ① rainy season or weeding, can use the rain gap to seize the species broadcast. ② vegetable field weeding. Appropriate protective accessories or with directional fan nozzle, so that the liquid sprinkled accurately between crops weeds, to the best effect of weeding in the field. ③ for planting or transplanting vegetables before cleaning the garden. Second, the use of methods Used before the emergence of vegetables, weeds early seedling stems and leaves spray or seedling protection spray. Ordered crops can be directed spray or spray protection. Use at weeds height no more than 15cm, spray evenly and evenly to ensure weeds are completely in contact with chemicals for optimal herbicidal effect. Third, the precautions ① spray to minimize the nozzle to prevent the fog full of drift to the nearby crop phytotoxicity. Â ’¡â- ¡Ke Wu trace and glyphosate in the soil as no residue, after treatment can be broadcast immediately or transplanting. ③ The rainfastness of the agent, spray after 1 hour of rain, will not affect the efficacy.
