|Weed Control in Hops||
Because hops are long-lived perennials, controlling weeds near plants without causing injury can be challenging. Furthermore, empty spaces between rows can quickly become filled with weeds if left unmanaged. Growers therefore need a year-round weed management plan. An important part of that plan is identifying the common weeds at the site and understanding their life cycles. Once weeds have been identified, a management plan can be developed using cultural, chemical, or integrated approaches.

|Plant Injury From Herbicide Residue||
In recent years, an increased number of cases of injury from herbicide residue in straw/hay, manure, and compost have been diagnosed in the Virginia Tech Plant Disease Clinic. Growers are surprised and dismayed to learn that manure, straw, mulch, or other amendments intended to improve their garden or landscape might have such unforeseen consequences. Of particular concern to organic growers are herbicide residues.
