for Peanut Leaf Spot Control
When Something Old Becomes New Again.
Protecting peanuts from costly defoliation and resulting yield losses caused by early and late leaf spot requires season-long management and a good rotation of active ingredients. This includes the ability to provide growers with the flexibility to tank-mix additional modes of action into their peanut disease programs.
Cultivars, weather, prior years with high leaf spot severity, and a variety of cultural practices can favor intense disease pressure during the growing season. Early and late leaf spot fungi overwinter in peanut crop debris. Old lesions on previously infected peanut leaves and stems produce spores that can infect the new crop. While most inoculum is local, spores can blow in from neighboring fields and occasionally over long distances, particularly during tropical storms.
“Peanuts are an ideal crop for an integrated pest management approach,” says Karen Westcott, Fungicide Lead for UPL. “Leaf spot remains a key disease worry for peanut growers, and we are happy to be able to bring an old-new product to peanut growers.”
Early and late leaf spot symptoms are first seen on leaves at the bottom of the plant. Later, the number of spots increase as the disease progresses. Plants begin to defoliate, starting with the bottom leaves and moving into the upper canopy. If leaf spot is present in your field, it can completely defoliate the entire crop. Control is necessary to prevent defoliation and yield loss of 50 percent or more. Typically, late leaf spot is more difficult to control — once it gets started it’s even more explosive than early leaf spot and can be a bigger challenge to manage.
