Pretty much everyone in the Florida Blueberry Industry knows what a challenging year it was. Remember Hurricane Ian, the December holiday freezes, huge crop input inflation, labor cost escalation and labor regulation, overall lower grower prices for our fruit, even increasingly serious insect pressure despite our best efforts.
Latest Research Shows Blueberry Roots Mining for the Essential Element
The two primary blueberry pests to monitor and control in fall and early winter are southern red mite and blueberry gall midge.
Many have heard the phrase “The Label is the Law,” and while true, labels convey so much more than the law. Every pesticide that is registered with the US Environmental Protection Agency (EPA) must go through rigorous testing, and then painstaking precision is used to write the label that goes on every product. These labels have information about what the product is, safety information, use information, storage, and disposal. Essentially, the label is the instruction manual for the pesticide. Although it may be tempting to simply jump straight to the application rate for your particular crop, this disregards very important information contained on the label. You must read and follow the entire label, not just the application rate for your crop.
We’ve officially made it through the first half of hurricane season. Now, we hold our breath through the month of October, which is typically the most active period for our state.
The table below lists suggested blueberry management items for October through January. Suggested management items for the entire calendar year are available in an EDIS publication, Calendar for Southern Highbush Blueberry Management in Florida (https://edis.ifas.ufl.edu/publication/HS1363). Specific disease, insect, and weed controls are listed in the 2022 Florida Blueberry IPM Guide (https://edis.ifas.ufl.edu/publication/HS380), as well as in subject-specific publications referenced below. Also, a list of all UF EDIS blueberry publications can be found at www.blueberrybreeding.com/blog, along with a summary description and link to each.
As fall approaches, some blueberry growers are likely considering the possibility of using hydrogen cyanamide (HC) to minimize the negative effects of inadequate winter chill accumulation, which can be a common occurrence in Florida. HC is not compatible with the evergreen or organic production systems. However, conventional growers who use the deciduous production system may find a use for HC depending on a number of factors.

The UF/IFAS Blueberry Growers Guide app contains modules with a scouting guide, a monthly management calendar, a pesticide guide, and detailed information on UF southern highbush blueberry cultivars, in both English and Spanish. It is available for download at https://tosto.re/blueberryuf.
Pruning is an essential part of blueberry production. It is used to promote postharvest growth
of new foliage and fruiting wood, balance vegetative and reproductive growth, reduce disease
and insect pressure, assist in mechanical harvesting efficiency, promote new cane growth and
plant longevity, and help establish new plantings.
Fungal leaf diseases can be a problem for Florida blueberry growers during summer months, including anthracnose, Phyllosticta leaf spot, rust, and target spot. This post is a quick reference guide to identifying these diseases from the symptoms (although some of these diseases can have symptoms that appear to be similar) and suggested chemical controls. Additional information on leaf diseases can be found in UF EDIS Publication PP348, Florida Blueberry Leaf Disease Guide (https://edis.ifas.ufl.edu/publication/PP348).

If you ask any Florida blueberry grower which season keeps them the busiest, they’re almost certain to tell you harvest season. But when you’re talking about blueberries, just as much as any other crop, the other seasons are no less important. In fact, summer is pretty pivotal to the success of your crop. That’s because the new growth that develops after your summer pruning but before terminal bud set in the fall will contain most of the flower buds for the following year’s crop.

Summer in Florida is wet, humid, and hot—great conditions for plant disease. Blueberries suffer from a range of summer problems caused by algal, fungal, and water mold pathogens. This article is meant to be an overview of some of the most important problems and ways to tie together management strategies over the summer that will cover the bases. Knowing what the typical symptoms of these diseases are and how to scout for them are critical first steps toward effectively managing healthy bushes through the summer months.
