Please be aware that Boxwood Blight Season is just around the corner. Last year the first observation of blight was the first week of March (i.e. keep an eye on this). If boxwood is important to your business, please follow the link below to the USPEST Boxwood Blight Risk Model. Here you can see the likelihood of boxwood blight development wherever you are in the state. You can also set up text alerts to make sure you stay on top of changing climatic conditions that impact disease development and spread. During this time of year, it is important to make sure sprayer equipment is calibrated and ready for deployment at moment’s notice, as boxwood blight development changes rapidly in concert with changing weather conditions.
