The subfreezing temperatures typically experienced during winter help act as nature’s defense against lurking diseases from one growing season to the next, but this year’s unusually warm winter has created prime conditions for disease pathogens and nematodes to thrive. In Peanut Grower, the University of Georgia Cooperative Extension urges growers to plan for the effects of a warm winter when determining peanut disease management programs for 2017.
Warm weather can spark outbreaks of white mold early in the season. This disease threatens peanuts along the soil line and near the soil surface, leading to the death of limbs and crown, which results in the destruction of pegs and pods. Extreme cold usually kills these pathogens in the winter, but sustained warm weather has allowed them to build up in fields over time.
Take extra precautions early in the growing season to prevent costly, yield-robbing infections of white mold. Syngenta recommends Elatus® fungicide for excellent white mold control in peanuts.
