Growth regulator herbicides for burndown applications
“In comparison with 2,4-D, dicamba provides greater control of chickweed, henbit and prickly lettuce, comparable control of dandelion, and less control of horseweed and mustard species,” said Hager.
Application rates used in burndown applications can impact the interval between application and planting. For example, Clarity can be applied at up to 16 fluid ounces per acre before planting corn (up to eight fluid ounces on coarse soils or medium- and fine-textured soils with less than 2.5 percent organic matter) with no interval between application and planting. However, the 16-ounce use rate requires a minimum accumulation of one inch of precipitation and a 28-day waiting interval between application and soybean planting. An eight-ounce application rate still requires a minimum accumulation of one inch of precipitation, but the waiting interval is only 14 days. These intervals must be observed prior to planting soybean or crop injury might occur.
