FALL WEED CONTROL

Fall is a good time to control winter annuals, quackgrass and other perennial weeds. The time between harvest and the first killing frost provides an excellent opportunity for weed growth and weed control. If fall growth allows, good control is possible. Spring pre-plant or in-crop control are good alternatives if fall applications are impractical. Generally, glyphosate is used for early spot treatment of quackgrass and 2 - 4, D is recommended in late fall before freeze-up for broadleaf weeds. A total field application of glyphosate is recommended only if excessive weed growth makes it necessary. If a fall seeded crop is to be planted, spray a day before or at least four days after seeding and before crop emergence A good marker or tramline system is important for accurate spraying in stubble.
