[QUOTE="TN Cattle Man, post: 1028569, member: 19746"] From UT Extension: [b]Management in Pastures and Hay Fields[/b] As is the case with most other weeds, prevention is an important component of an overall management plan. In the case of horsenet-tle, feeding infested hay is the one of the primary ways the weed is introduced into a field. If possible, buy clean hay of known ori-gin.
