Getting Ahead with these Spring Weed Management Reminders

Weeds compete with blueberry for water and nutrients, which inhibits bush growth and yield. Weed control options include preventative, mechanical, and chemical weed control options. A proper ID of weeds is important for selecting the correct method of control.

Ongoing research in our program is evaluating the potential use of sparkleberry (Vaccinium arboreum) as a rootstock for southern highbush blueberry (SHB). Blueberry plants are shallow-rooted and require soils with low pH and high organic matter content. Under current management systems in the southeastern U.S., SHB is frequently subjected to a variety of stresses including periodic drought stress, and adverse soil conditions such as insufficient soil organic matter and/ or high soil pH. Moreover, the multi-cane SHB crown is not adapted to the current mechanical harvester designs because catch plates do not seal effectively around the base of plants. The result is fruit dropping to the ground during machine harvesting (see Figure 1).

<strong>Beetles vs Blueberries</strong>

Post-harvest foliage management is important for blueberries produced in both deciduous and evergreen systems in Florida.  Healthy leaves maintained through flower bud differentiation in fall will ensure sufficient carbohydrate (sugar) reserves for uniform, early, berry production and leafing the following spring in deciduous production.  In evergreen systems, foliar diseases that carry over on leaves reduce the vigor of plants, but also can produce spores that infect fruit.  Anthracnose and rust pathogens infect both leaves and fruit and can lead to post harvest fruit rot (ripe rot) and fruit quality issues (rust infection of fruit).  Some varieties are more susceptible to summer foliar diseases than others.  Jewel is an older variety still widely grown that suffers from several foliar fungal diseases during the hot humid Florida summers.

<strong>Helping Farmers Develop Efficient Water Practices</strong>

It appears that specialty crops – including blueberries – are taking a back seat in the current negotiations over the North American Free Trade Agreement as arguments over tariffs and other higher priority items are being discussed.
