氯氟吡氧乙酸是内吸传导型苗后除草剂,广泛用于小麦、玉米、水稻田防除阔叶杂草。杂草吸收药液后,出现典型激素类除草剂的药害症状:植株畸形、扭曲,最终枯死。氯氟吡氧乙酸使用不当容易产生药害,2016年7月份笔者接到电话反映在水稻苗后除草,出现药害;今年3月份笔者又接到电话,氯氟吡氧乙酸在小麦田出现药害。经过实地查看,确实都出现药害,但发生药害的原因却不尽相同,下面我们仔细分析一下氯氟吡氧
Flupthionine is a systemic herbicide that acts as a conduction-type post-emergence herbicide and is widely used in the control of broadleaf weeds in wheat, corn and paddy fields. Weed absorption of liquid medicine, the emergence of typical hormone herbicide symptoms: plant deformity, distortion, and ultimately dead. Fluroxypyr was improperly used to produce phytotoxicity. In July 2016, the author received a phone call to reflect the phytotoxicity of rice after weeding. In March this year, the author received another telephone call and flumorph appears in the wheat field harm. After field inspection, there are indeed drug injury, but the reasons for the occurrence of injury are not the same, let's carefully analyze the cloverpyrro
