Foliage-applied herbicides

Uses nonselective, foliage-applied herbicide in uncropped land and orchards to control perennial weeds in certain grasses.

Uses Selective contact foliage-applied herbicide used to control maty broad-leaved weeds in cereals. 

Clacyfos exhibited xylem mobility. It exhibited good inhibitory effect on plant growth through either foliar and stem spray or root application. The inhibitory effect was most significant through foliar application. Therefore, clacyfos is recommended as a post-emergence, foliage-applied herbicide. 

Pathways and Mechanisms of Uptake of Foliage-Applied Herbicides... 

Activator adjuvants are often added to spray mixtures of foliage-applied herbicides to enhance the level of weed control. Such adjuvants increase herbicidal activity by increasing cuticle retention, penetration, absorption, and possibly translocation. Activator adjuvants include surfactants, wetting agents, penetrants, and oils. Oils used as additives have been found to influence wetting properties, evaporation, leaching, and foliar uptake and translocation of herbicides while surfactants increase their solubility, spreading, and penetration.
