Texas A&M AgriLife Extension has released a new spray guide for grapes grown in Texas. The really interesting part for those of us who live outside of Texas, but near the Gulf, is the section on pages 12-15 that target hybrid bunch grapes — namely Blanc du Bois and Lenoir. These two cultivars have potential in Mississippi and other Gulf States. Disease management is critical for success and this gives guide gives a good place to start. As always, make sure the products are labeled in your state and follow the label.
