Aquatic Weed Control
Get the jump on annoying weed problems that interfere with the use of ponds and lakes. Herbicides are useful, but careful consideration must be given to the intended use of the water.
Weed Tour Reminder
The Nebraska Weed Tour is scheduled for Concord and Lincoln on June 22 and Clay Center on June 23. The Tour continues at North Platte and Sidney on June 24 and concludes at Scottsbluff on June 25.
Pasture and Range Weed Control
Again the growing season is ahead of normal over much of Nebraska and so are pasture and grazing-land weeds. Normally the later part of June is the best time to treat broom snakeweed, vervain, goldenrod" sagebrush, snow-on-the-mountain, and western ragweed. With the advanced growing season, these weeds should be in the correct stage for treatment over much of Nebraska by mid-June. There's a tendency. to treat on the late side rather than too early. A good guideline for treating most perennials is to mow or apply the herbicide when the weeds are in the early flower bud stage. Biennial thistles are an exception and should be treated in the rosette stage.
Brush and Woody Plant Control
June is the best time for foliar applications of most herbicides for woody plant control. Thorough coverage of the foliage gives the best control. Woody plants are now in full leaf and the foliage is tender. Later in the summer the plants are often stressed due to dry conditions resulting in lessened herbicide effect.
