Summary. Moisture is the most limiting factor to dryland crop production in western Kansas. As cropping intensity is increased from a wheat-fallow rotation to a wheat-summer cropfallow rotation, moisture efficiency becomes the most critical factor that leads to a successful cropping system. For these reasons, there is very little tolerance for weed development and growth in the more intensive…
Summary. Herbicides are chemicals that inhibit or interrupt normal plant growth and development. They are widely used in agriculture, industry, and urban areas for weed management. Herbicides can provide cost-effective weed control while minimizing labor. However, improper herbicide use may result in crop injury, poor weed control, herbicide resistant weeds, environmental contamination, or hea…
