Harmony — a modern post-emergence herbicide for controlling broadleaf weeds, controls a wide spectrum of troublesome weeds in corn, cereal, and flax crops.
Active ingredient
750 g/kg tebufen sulfuron-methyl
Base unit
100 g.
Harmony is primarily absorbed by weed leaves and rapidly translocated after application to the root and stem growth zones.
Harmony stops the cell division of susceptible weeds by affecting an enzyme system that does not exist in the human or warm-blooded animal body. Susceptible weeds practically stop growing immediately and no longer compete with crop plants for water and mineral nutrients. Visible symptoms, such as growth cessation, chlorosis, apical dieback, and necrosis, appear within 2-3 days after application. Death of susceptible weeds may take 10-20 days. More resistant weeds or those at a later growth stage at the time of application may temporarily halt their growth during the vegetative period, but they no longer pose a competitive threat to crop plants.
Harmony affects weeds within several hours after application. Since the product acts on an enzyme system, visible symptoms appear slowly. This is not related to the product's efficacy, but is a consequence of its specific mode of action.
When applied at recommended doses, Harmony exhibits excellent selectivity for corn, cereal, and flax crops, as the active ingredient rapidly degrades in these crops.
Harmony rapidly degrades in soil due to microbial breakdown and chemical hydrolysis, with a half-life of 6 days.
Thus, any subsequent crop can be sown immediately after harvest, provided normal crop rotation is followed.
