Updated registered pesticide list for chestnut producers for 2014
New pesticide quick reference available for Michigan chestnut growers through Michigan State University Extension.
In an effort to assist chestnut growers in making pesticide decisions, a new quick reference for pesticides registered for edible chestnuts in 2014 has been created and is available for download at the Michigan State University Chestnuts website under Pest Management. Chestnuts belong to Crop Group 14 (Tree Nuts) as defined by the Environmental Protection Agency (EPA). Crop groups have helped streamline the pesticide registration and labeling process and are based on similar biological traits, edible parts, dietary consumption, geographical distribution, economic importance and growing practices. For example, the Tree Nut crop group contains other edible nuts including almonds and pecans. Tolerance information for a given pesticide is based on research in a representative crop and may be extended to similar crops within the same crop group. This has allowed for a substantial increase in the accessibility of pesticides to specialty crop producers.
There are two types of pesticide labels that can apply to chestnut trees: Agriculture/Crop Protection labels for trees from which nuts will be harvested for consumption, and Turf and Ornamental/Non-Crop labels which apply to ornamental trees from which nuts will not be harvested for consumption. Specific products may be labeled for chestnut trees that fall into one or both of these categories, but for the legal use of a pesticide on chestnuts for nut production it must have an Agriculture/Crop Protection label. The practices surrounding proper use may vary greatly between these two label types and growers should read and closely follow the Agriculture/Crop Protection label carefully.
Michigan State University Extension encourages growers to reference the Crop Data Management Systems website to retrieve the latest labels and determine if the product is meant for food or nonfood crop application. For more information on how to read a pesticide label, refer to the Pennsylvania State Extension article, “What you need to know about reading a pesticide label.” This fact sheet is also available in Spanish. See more additional resources regarding pesticide safety from Pennsylvania State Extension.
To protect you, others and the environment, always read the label before applying any pesticide. Although efforts have been made to check the accuracy of information presented, it is the responsibility of the person using this information to verify that it is correct by reading the corresponding pesticide label in its entirety before using the product.
