Plants require seven micronutrients: boron (B), chlorine (Cl), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), and zinc (Zn). In Nebraska, deficiencies of iron and zinc can be common, depending on soil properties, but deficiencies of the other five micronutrients are rare.
Jenny Rees, extension educator in Clay County, said growers are reporting greenbugs (Figure 1) in sorghum and corn leaf aphids (Figure 2) on corn in south central Nebraska.
