The dry weather we have had recently has had some benefits to farmers, according to my conversations with extension agents and this article from Vegetable and Specialty Crop News. Due to the low humidity and lack of rain to splash soil microbe onto the plants, disease pressure from fungal diseases is very low. This is great news for the farmers, since they can spend less time dealing with the problems caused by these diseases, although of course they need to continue to scout for outbreaks.
