Volume 57 Number 11 Date 06/21/2012 MUSK THISTLE - Tall, flowering stalks are transitioning into the seed production phase of development across the southern counties. This aggressive, biennial weed spreads only by seed, so mowing should occur prior to seed set to reduce the vigor of stands and minimize seed production. Thistle populations are particularly difficult to control in pasture settings where cattle avoid consuming the prickly leaves, but brush against the plants, aiding in seed dispersal. --Clarissa Hammond, DATCP Weed Scientist
