How Well Will Pre-Emergence Herbicides Work in 2021?
It is always good to start with a pre-emergence program to prevent weeds from becoming resistant. With the spring starting out below normal in subsoil, there are questions as to how well preemergent herbicides will work.

Weed Control: Pulse Crops
Weed competition can cause significant yield reduction in pulse crops. Pulse crops are weak competitors with weeds, therefore planning an effective weed control program is one of the keys to profitable production.

Best Management Practices for Wheat Production
The Wheat Best Management Practices manual offers a comprehensive guide for optimizing yields, maximizing profits and ensuring long-term sustainability in wheat production.

Plan Now to Control Weeds With Grazing Next Season
Livestock will graze Canada goldenrod, Canada thistle and perennial sow thistle. At certain times of the year, these plants have crude protein, total digestible nutrients, and invitro dry matter digestibility concentrations similar to alfalfa and other common forages.

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.
