Insect/Plant Interactions Between 6 and 14 Leaf Brix

It’s often stated that achieving a leaf brix of 12 in the canopy will protect your plants from insects and disease. But is this true? Will insects be deterred at lower brix levels, and what factors increase or decrease brix? Gainesville, Fla.-based entomologist Thomas Dykstra will demystify some of the confusion surrounding leaf brix by hosting an informal discussion involving brix numbers and how they relate to insect damage. He’ll also cover how to use a brix refractometer. Bring your questions, a notebook and an open mind as Dykstra introduces you to the world of insect/plant interactions.
