Blueberry Pest Management

Marice Lopez, Patricio Munoz, and Oscar Liburd

The blueberry gall midge (BGM) is one of the most important pests of southern highbush blueberries in Florida. Monitoring for BGM using clear sticky traps or bucket traps should begin as early as November. Chemical control should be applied right before bud break and then ten days after bud break, or when at least two BGM are found on traps. Other management practices include the use of younger mulch, using potentially resistant cultivars, and chemical control such as Movento with Induce and Apta in rotation to avoid resistance development. Applications should also be timed with larval and adult emergence for optimal insecticide efficacy.

This publication is intended to be a resource for Florida blueberry growers to use in scouting for disease and insect/mite pest damage; managing disease, insect/mite pests, and weeds; and application of certain plant growth regulators.

This publication provides blueberry growers strategies for choosing and applying fungicides and insecticides during bloom so as to minimize harm to pollinators. Insect pollinators, particularly wild and managed bees, are necessary to achieve adequate fruit set in blueberries. Without insect pollinators, berries may form, but they will be significantly smaller and misshapen and will take longer to ripen than bee-pollinated berries. Managed bees, wild bees, and other insect pollinators are susceptible to pesticides, especially when applied during bloom when pollinators are foraging in blueberry fields. Growers thus must balance disease and pest protection with pollinator protection. This publication provides information on the toxicity to pollinators and residual activity of insecticides and fungicides used during blueberry bloom, and strategies for minimizing pollinator exposure.
