Giant knotweed (Reynoutria sachalinensis, RS) extract is a known elicitor of plant defenses but its mode of action remains elusive. Extract from giant knotweed (Reynoutria sachalinensis) sold as MILSANA® and REGALIA® by Marrone Bio Innovations, Inc. provides control of powdery mildew and other plant diseases on cucurbits and other crops mainly by inducing an accumulation of fungitoxic phenolic compounds in the plant (Daayf et al., 1995; Wurms et al. These findings clearly indicate that RS elicits plant defenses notably as a consequence of SA pathway induction. Metobromuron. When applied at rates and timing for plant health effects, the response results in minimized impact of abiotic stress resulting in optimized yields at harvest.
