Weed Control and Herbicide Applications

Widespread use of the triazine herbicides for weed control on corn, sorghum, sugarcane and fruit crop acreage has resulted in efficient, low-cost effective weed control on tens of millions of acres for the past thirty years. Many growers make a single application of a triazine herbicide at planting. The triazines stay active in the soil for five to six weeks and control most important broadleaf weeds and several important grass weeds. By mixing the triazine herbicides with an herbicide active on grass weeds, the single application is often all that is required for season-long weed control. The triazines cost approximately $8-10 less per acre of corn than available alternatives. For the minor acreage crops, such as sugarcane and fruit crops, for which there are fewer alternatives, the savings of using triazines amount to $50-70 per acre. One reason that growers readily adopt the triazines is their excellent crop safety record. U. S. farmers have used the triazine herbicides on a majority of U. S. crop acres for thirty years because of the weed control benefits they provide at an economical cost.
