This publication was adapted for Florida from the Southeast Regional Blueberry Integrated Management Guide, available at http://www.smallfruits.org/SmallFruitsRegGuide/Guides/2006/12Jan06BlueberrySprayGuide.pdf. Thus, major contributions were made by the original editors: Gerard Krewer, Phil Brannen, Mark Czarnota, Dan Horton, Paul Guillebeau, and Paul Sumner (University of Georgia); Bill Cline, Hannah Barrack, Katie Jennings, Wayne Mitchem, and David Monks (North Carolina State University); Frank Hale and David Lockwood (University of Tennessee); and Powell Smith and Bob Bellinger (Clemson University).
Additional contributions by Allen Straw (Virginia Tech University), Scott Nesmith and Harald Scherm (University of Georgia), John Meyer (North Carolina State University), Steve Bost (University of Tennessee), and Blair Sampson (USDA/ARS Small Fruit Res. Station, Poplarville, MS).
Recommendations are based on information from the manufacturer’s label and performance data from research and Extension field tests.
Because environmental conditions and grower application methods vary widely, suggested use does not imply that performance of the pesticide will always conform to the
safety and pest control standards indicated by experimental data.
This publication is intended for use only as a guide. Specific rates and application methods are on the pesticide label, and these are subject to change at any time. Always refer to and read the pesticide label before making any application! The pesticide label supersedes any information contained in this guide, and it is the legal document referenced for application standards.

Pesticide Safety and Label Interpretation Resources:
• Federal Regulations Affecting Use of Pesticides (http://edis.ifas.ufl.edu/pi168)
• Interpreting Pesticide Label Wording (http://edis.ifas.ufl.edu/pi071)
• Toxicity of Pesticides (http://edis.ifas.ufl.edu/pi008)
Sprayer Calibration: Sprayer calibration is very important. Sprayers should be calibrated often to guard against ac-cidentally using excess pesticides because of nozzle wear, speed increases, and other calibration problems. Failing to calibrate often costs money, may cause crop damage, and is unsafe.

Blueberry Integrated Management Guide (Insect and Disease Control)EstablishmentRoot rots – Blueberry root rots can be particularly prob-lematic immediately after transplanting and until plants are well established. Even in well-drained soils, root rots have been observed in bark-amended beds, and root rots are particularly damaging in high-density bark beds, even when using new bark. Though cost is an issue, replanting into old bark (high-density plantings) is not a good prac-tice; disease-causing organisms build up in the bark, and they can make reestablishment very difficult. It is recom-mended that phosphite-containing materials (Aliette®, ProPhyt®, Agri-Fos®, etc.) be used on nonbearing plants after establishment (for bedded and high-density bark plant-ings). These materials are applied to leaves; therefore, leaf
tissue must be fully expanded for them to be taken up by plants. In the initial year of planting, a minimum of four ap-plications (spaced approximately 30 days apart) is advisable. In general, phosphite materials are acidic, and they should not be applied with acidifiers or acidic water (pH < 6).
Excessive application or application intervals shorter than those dictated by the label will injure plants. These phosphite materials also suppress Septoria leaf spot and anthracnose, which are major foliar diseases of young plants. Some phosphonate materials are labeled for use as drenches or chemigation, but information on the success of these methods in southern blueberry production is limited.
In high-density bark beds, Ridomil Gold® EC also provides good control of Pythium and Phytophthora root rots; however, using Ridomil Gold® EC in field plantings is very expensive and difficult since the product has to be taken up by the roots for activity. Where possible, rotating Ridomil Gold® EC and phosphites is a good resistance-management practice. Do not exceed label recommendations.
PostestablishmentBlueberry gall midge – The blueberry gall midge is a tiny fly whose larvae feed on vegetative and floral buds. On rab-biteye cultivars, the blueberry gall midge occurs frequently, but it normally only causes economic levels of damage on susceptible cultivars. Blueberry gall midge can become a major problem on some rabbiteye cultivars. Feeding injury destroys floral and vegetative buds before the bud scales open in the spring. In southern highbush blueberries (SHB), blueberry gall midge is observed less frequently than on rabbiteye, but SHB may show symptoms on new growth. Gall midges lay eggs on warm winter days and at any time during the growing season when the plants are making new flushes of growth. For control, apply Delegate® or diazinon (if labeled for use on your site) as needed for gall midge between flower bud stages 1 and 2, when the most mature buds first show slight scale separation. Repeat sprays during warm spells if necessary. Bud scale separation may occur as early as 15 December in north Florida. In rabbiteye, ‘Premier’ is often particularly attractive to the gall midge and is a good sentinel variety to monitor. Gall midge sprays can also suppress a prebloom thrips population.
Flower thrips – These are small insects (1/16 of an inch in length) with yellowish to orange coloration and fringed wings. Flower thrips damage blueberry flowers in two ways. Larvae and adults feed on all parts of the flowers, including ovaries, styles, petals, and developing fruit. This feeding damage can reduce the quality and quantity of the fruit.
3
Females damage the fruit when they lay their eggs inside flower tissues. The newly hatched larvae bore holes in the flower tissues when they emerge. White, blue, and yellow sticky traps can be used to monitor thrips. White traps are preferred over blue and yellow because the thrips show up best against a light background and because the white traps do not attract as many beneficial insects as yellow traps. Another technique for monitoring thrips involves gently tapping the flowers and allowing the thrips to fall onto a white sheet of paper below for counting. An economic injury level (EIL), the lowest number of thrips that can cause economic damage in blueberries, has been developed for two popular rabbiteye cultivars, ‘Tifblue’ and ‘Climax’. During bloom, when thrips numbers reach approximately 68 thrips per trap for ‘Tifblue’ and 75 thrips per trap for ‘Climax’ in a week, insecticide applications should be considered. It is recommended that growers use Delegate® WG at 6 oz. per acre to manage flower thrips populations in Florida blueberries (rabbiteye and southern highbush).
Blueberry bud mite – The blueberry bud mite is an eri-ophyid mite so tiny (1/125 inch long) that it cannot be seen without magnification. Blueberry bud mite is an occasional pest in well-established blueberries in Florida. Bud mite injury is often confused with frost damage and may become more visible in late spring. In early spring, infested plants exhibit stunted, succulent, fleshy, closely packed, reddish rosetted buds, which may dry up and often fail to open. Bloom on infested plants is reduced. Affected berries are small and rough and may have small, reddish pimples or blisters on the fruit surface. Sanitation by aggressive, timely pruning of infested branches can be helpful. Mechanical topping (mowing off old fruiting twigs) immediately after harvest greatly reduces bud mite incidence the following year. Never propagate from bushes that may be infested with blueberry bud mite. Horticultural oil applications immediately after harvest aid in control.
Imported fire ants – Ant baits employed in early spring as a broadcast treatment usually eliminate most but not all fire ant mounds within treated areas. Under high ant pressure, treating a second time in the fall provides better fire ant control. Most ant baits are slow acting and require up to 8 weeks to control active mounds. Worker ants must be attracted to baits so that they will carry the baits back to their colonies. Most ant baits interfere with reproduction, causing a gradual colony die-off. Extinguish® Professional Fire Ant Bait (0.5% methoprene) is labeled for use on all crop land sites. It is effective but somewhat slower acting than Esteem® Ant Bait (0.5% pyriproxyfen).
Ant baits work best when the soil is moist but not wet. Active ant foraging is essential. Ideally, temperatures should be warm and sunny. Avoid applying ant baits when condi-tions are expected to be cold, overcast, rainy, or very hot. Individual mound treatments are most effective when used as-needed for the occasional colony that survives broadcast treatments. Mound treatments using insecticide baits should be applied in a circle 3–4 feet from the mound. Do not disturb mounds or place bait directly on top of mounds.
Mummy berry – Mummy berry is currently not identified as an important disease of southern highbush blueberry in Florida. The disease is a major issue in production areas north of Florida. Florida growers concerned about potential mummy berry problems are encouraged to contact county Extension for diagnostic confirmation and additional information.
Phytophthora root rot – Root rot is generally a problem of low-lying, poorly drained sites. To avoid root rot, provide adequate drainage by constructing raised beds before planting. Site selection and/or proper bedding operations are essential cultural practices for disease control. Treat-ment with fungicides is not effective for reversing root rot damage on plants with severe symptoms. Preventative fungicide treatments in pine bark beds and poorly drained sites may be warranted since the beds are often saturated with water either by irrigation or rainfall.
