Biorational and Organic Disease Control Materials (Table 26)

This table consists of botanical, mineral, and synthetic disease control materials labeled for use in vegetable crops that are relatively non-toxic to people and have few environmental side-effects. Most of these materials are broadly labeled for vegetable crops, unless otherwise noted. Use on vegetable crops in greenhouses and high tunnels is allowed unless noted in Comments column.
