Late planted wheatBy David G. Hallauer Meadowlark District Extension Agent, crops and soils/horticulture Kansas If weather and this season's slightly later harvest have prevented your wheat planting, you might want to evaluate seeding rate before you pull the drill in to the field. Typical Kansas State University recommendations call for an increase in seeding rate after late October/early November. Increase that rate to 100 to 120 pounds here in Eastern Kansas. If you're already at the top end of that range, no additional increase should be necessary in most cases. Starter fertilizer also becomes increasingly important at this time. This will help roots get started in cooler, wetter soils. Later fall seedings just don't get the fall growth and tillering that get lower seeding rates or lower fertility rates started appropriately. Give some consideration to giving that wheat crop a head start if you haven't been fortunate enough to get it planted just yet. Control broadleaf weeds in lawns in early November Early November is the most effective time to control broadleaf weeds in lawns. Dandelions usually produce a flush of new plants in late September, and the winter annual weeds henbit and chickweed should have germinated in October. These young plants are small and easily controlled with herbicides such as 2,4-D or combination products (Trimec, Weed-B-Gon, Weed-Out) that contain 2,4-D, MCPP and Dicamba. Even established dandelions are more easily controlled now than in the spring because they are actively moving materials from the top portion of the plant to the roots. Herbicides will translocate to the roots as well and will kill the plant from the roots up. Be sure to choose a day that is 50 degrees or higher. The better the weed is growing, the more weed killer will be moved from the leaves to the roots. Cold temperatures will slow or stop this process. Weed Free Zone (also sold under the name of Speed Zone) is a relatively new herbicide and contains the three active ingredients mentioned above plus carfentrazone. It gives a quicker response than the other products mentioned and will work better when temperatures drop below 50 degrees. 11/10/08 Date: 11/6/08 Advertisement
