Noxious Weed Control in Pasture and Range
Noxious weed control in pastures is becoming more of a challenge. Most ground commercial spray businesses are no longer spraying pastures. If they are, there may be restrictions on the time they will spray, what products they will spray, or they may only spray if they also have all of the rest of your spraying business.
Lawn Weed Control
Cultural weed control practices must be included in weed management programs to optimize control and inhibit re-infestation. A healthy, dense turf cover is the best overall defense against weed invasion. Some common cultural weed control practices include planting the most adapted turfgrass species for your environment (i.e. shade, full sun, or hot, dry conditions), maintaining a mowing height of 2.5–3.5 inches, watering deeply but less frequently, and proper soil maintenance including fertilization and core aerification.
Grassy Weeds
Grassy weeds are a problem in all field crops. They must be identified at early stages of growth so they can be controlled before crop yields are seriously threatened. Control measures are not the same for all grassy weeds, so accurate seedling identification is important.
