leafy spurge, noxious weed, fall control
Leafy spurge is an especially difficult noxious weed. Fall control is an essential part of a leafy spurge control program. Retreatment is required for 2,4-D. Fall herbicides are effective where sheep or goats have grazed. Fall is a good time to apply spot treatment herbicides. It is the only time some fencelines and field corners are accessible.
