The rate of volatilisation of the formulated herbicide triallate was investigated in a wind tunnel under controlled wind-speed conditions. An experimental set-up is described which allows the monitoring of wind speed (w.s.), soil-water content, and the temperature of air and soil. A system controlling soil-water content is also described. The influence of air velocity and soil texture was investigated measuring the cumulative volatilisation losses of triallate from soil. The herbicide volatilisation losses after application ranged from 40% at 3 m/s to 53% at 9 m/s for loam soil and from 60% at 3 m/s to 73% at 9 m/s for sandy soil.
在可控风速条件下的风洞中，对配方除草剂野麦畏的挥发速率进行了研究。描述了一种实验装置，该装置可监测风速、土壤含水量以及空气和土壤的温度。还描述了一种控制土壤含水量的系统。通过测量野麦畏从土壤中的累积挥发损失，研究了风速和土壤质地的影响。对于壤土，施药后除草剂的挥发损失在3米/秒时为40%，在9米/秒时为53%；对于砂土，在3米/秒时为60%，在9米/秒时为73%。
