Thin, uneven and stunted alfalfa can often be caused by possible herbicide carryover. Traditional broadleaf alfalfa herbicides typically used in the spring should not be applied in the fall due to increased risk of winter injury. We didn’t just combine two names. (See NebGuide G1891, A Quick Test for Herbicide Carryover in the Soil.) When soils are very dry, herbicide breakdown via microbiological activity is diminished.

This is especially important after drought years and on fields where high herbicide application rates or Source link here. As you’re planning for next year and evaluating your forage needs, ask yourself, “What can I improve next year with my alfalfa production?” In addition to more yield and higher forage quality, harvest management flexibility might be a priority. Attempts to predict the extent of carryover and damage to sensitive crops the year following atrazine use have been only partially successful. The potential for herbicide carryover injury is driven by two main factors: Concentration of available herbicide remaining in the soil at the time of rotational crop planting. Avoid seeding alfalfa into soils that contain residual herbicides from previous crops. Atrazine rates over 0.75 pounds per acre on our soils in fields where crop yields were low would be of concern. … Weather • Precipitation (< 15 in) • Temperature (cool) 4.
