By Doug Phillips The Blueberry Advisory System (BAS) is a weather-based alert system that signals Florida blueberry growers when environmental conditions are favorable for the development of anthracnose fruit rot (AFR). A new, updated version of the BAS was released on Jan. 31, available at http://agroclimate.org/tools/bas/. The data for AFR risk models is collected from the Florida Automated Weather Network, which has weather stations throughout the state. The risk for AFR …
Nutsedge Control in Blueberries
By Peter Dittmar All weeds are problematic in blueberry production because they compete for water and nutrients, hinder harvest crews and decrease yields. One of the most problematic weeds in blueberry is nutsedge (Figure 1). The two species of perennial nutsedge in Florida are yellow (Cyperus esculentus) and purple nutsedge (C. rotundus). These weeds are difficult to control because of …
Tips for Gall Midge Management
By Oscar Liburd and Doug Phillips Blueberry gall midge is a small fly that feeds on the floral and vegetative buds of blueberries. Reports of gall midge damage on blueberries grown in Florida have become more common in recent years. In cases where there was severe feeding injury to floral buds, the midge can significantly affect yield. DESCRIPTION AND LIFE …
Disease Management Update for Georgia Blueberries
By Jonathan Oliver In 2019, Georgia blueberry production rebounded from the effects of the devastating late freezes in 2017 and 2018. Nonetheless, blueberry producers in the southeastern United States must contend annually with environmental factors such as heat and humidity that can provide an ideal climate for the development of disease issues.

Evaluating Methods to Reduce Runoff in Blueberry Beds
By Gary L. Hawkins Water and nutrients are needed items for plant growth, and blueberries are no different. However, when nutrients leach below the root zone that is a loss for the farmer. Where water tables are high and farmers use subsurface tile drains to remove excess water, mobile nutrients such as nitrogen in the form of nitrate can cause …
