The UF/IFAS Blueberry Breeding Program has released a new pesticide module as part of its UF/IFAS Blueberry Growers Guide app. This new module is a quick reference guide for certain information on pesticides labeled for highbush blueberry in Florida, including:

The table below lists suggested blueberry management items for spring and early summer. 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.

USHBC’s BerrySmart Field initiative is a collaborative experience among growers, researchers and tech providers to optimize blueberry farming operations, focusing on soil, soil nutrients, yield distribution, weather, chemicals, and labor. As part of this initiative, we’re working in partnership with innov8.ag to validate a smart farm network that enables blueberry growers, packers and stakeholders in sales, tech and research to collaborate on farm operation optimization with better and more predictable yield outcomes.

The UF/IFAS Blueberry Breeding Program is releasing a new pesticide module on February 6, as part of its UF/IFAS Blueberry Growers Guide app.

Managed Bumble Bees Are a Great Way to Bolster Pollination

Are they right for me?

December – January 

As we rang in the new year, many of us were thankful that Jack Frost was no longer nipping at our nose … or crops, for that matter.

This year is one of transition for the FBGA Board membership. Several old hands who have guided us through challenging years are stepping down to focus on other important obligations with their endorsement of the concept that new board members bring new perspectives and ideas to refresh the board and broaden its inclusion of other growing regions.  

Proper Irrigation Is Critical for Blueberries in Late Winter and Spring 

Protection Checklist

Virtually all blueberry fields in Florida are subject to late winter or early spring freezes that can cause serious reductions in yield. Below is a list of activities for freeze preparation. The list was originally published by Mike Mainland in the North Carolina Blueberry News, Vol. 7, No. 1and has been modified by IFAS faculty and FBGA board members. 

Newer Acaricides Effective in Fighting Blueberry Bud Mite 

Integrated Approach is Best for Botrytis Blossom Blight

Botrytis blossom blight is an early-season disease impacting southern highbush blueberries. Although not frequently observed causing severe damage in Florida fields most years, infections starting during bloom can later develop into gray mold, which has become an important postharvest disease. The fungal pathogen, Botrytis cinerea, typically infects wounded or senescent floral tissues. As a blueberry bush blooms, white bell-shaped corollas (the fused petal of the flowers) should drop from the flower following pollination but before they senesce (turn brown). However, frost damage can wound plant tissues, delaying petal drop and facilitating infection of the flowers, undeveloped fruit, and damaged twigs and leaves. The pathogen survives in these dead and wounded plant tissues on the blueberry bush and on nearby weedy plants as well. Spores from these sources are abundantly produced when cool, wet periods occur during blueberry bloom through harvest.

Council Launches Several Initiatives to Advance the Blueberry Industry in 2023

As 2022 comes to a close, the U.S. Highbush Blueberry Council (USHBC) is preparing to launch a number of promotion programs to help ensure a successful 2023 for the blueberry industry!

Newest Cultivar 'Albus' Set for Release This Summer

The UF/IFAS blueberry breeding program has developed many southern highbush blueberry cultivars, which make up most of the commercial production acreage in Florida today. In 2021,  the program released “Sentinel,” a vigorous, early-season, high-yielding cultivar that has scored high in consumer taste panels. It has performed well in both North-Central and Central Florida trial sites, and trials are being conducted in South-Central Florida to determine its production in that region. 

Fall and Early Winter Suggested Blueberry Management Items

 Fall/Winter Irrigation and Fertilization Are Key to Bud Formation and Cold Acclimation

Fall may seem like a quiet time in blueberry fields, but important processes are silently occurring such as flower bud formation for next year’s crop and cold acclimation for the upcoming winter. When blueberry plants enter fall, they should have developed a canopy of moderately vigorous shoots with healthy leaves that developed following postharvest pruning during the summer. 

The Blueberry Advisory System, a Grower Tool for Timing Anthracnose Fruit Rot Controls

Anthracnose fruit rot (AFR), also called ripe rot, is a fungal disease that can damage blueberry fruit, resulting in sunken lesions, softening, shriveling, and rotting of berries, along with eruptions of salmon-orange masses of spores. Symptoms typically start at the blossom end of the berry and cause the fruit to be unmarketable, affecting pack-out percentages and grower revenues. AFR infections can occur as early as bloom, with symptoms often not appearing until the fruit ripens or after it has been harvested and stored. Warm, wet weather is conducive to the development of AFR, with temperatures between 59-81°F (15-27°C) and leaf wetness duration of more than 12 hours the most favorable for infection. Rainfall or overhead irrigation disperses the pathogen to uninfected fruit and plants, creating additional opportunities for infection. The pathogen can also be spread by fruit-to-fruit contact, harvesting machinery, and sorting equipment.
