Abstract

Metham was applied in the dormant season to established cranberry for the control of false lily-of-the-valley. Rates of 108 to 214 kg ai/ha controlled false lily-of the-valley, but there were inconsistent results between years and fields. Soil temperature, organic matter content, and amount of water used for incorporation appeared to be important factors in determining results. The phytotoxicity of metham sodium to cranberry was sporadic, ranging from moderate at 214 kg ai/ha to severe at 108 kg ai/ha. The 142 kg ai/ha rate usually resulted in an acceptable level of crop injury. Sanding the bog after application reduced phytotoxicity and heat stress increased it.
