Recently, trace amounts of white mold were confirmed in an Extension Peanut Fungicide trial conducted in Santa Rosa County, Florida.
White Mold Description and Details
White mold is a fungal pathogen and a soilborne disease. It appears as a small BB-like, mustard-sized seed that germinates and infects the peanut crop. Hits of white mold are almost unpreventable, especially in warm, wet years such as these. These hits should be heavily monitored and managed to prevent future spreading. Fortunately, white mold is very easy to detect. Unfortunately, it’s not so easy to completely wipe out.
White Mold Treatment Strategies and Solutions
To prevent the spread of white mold, it is paramount that peanut growers enact a solid fungicide program early on in the peanut planting process.
Even so, no fungicide that is used for peanuts can totally wipe out the white mold from a field. Even with the enactment of a sound treatment plan, the fungicide will only kill about 70% of the fungus. To really minimize the risk and manage a current white mold break out, requires the practice of good crop rotation and the use of more resistant, newer peanut varieties.
If you find that white mold is becoming a huge problem, it’s important to deduce the root cause of it. Check if your sprayer is properly calibrated. Make sure the application rate of the fungicide is appropriate. Timing is everything. Perhaps consider shortening the interval time between fungicide applications. Consider applying the fungicide at night or in the early morning hours to allow better penetration. There are many proven techniques that you can implement to better reduce the risk of white mold spreading and ruining your peanut crop.
