Product rotation suggestions to manage CPB larvae over a three-year interval. Programs A-G alternate IRAC Mode of Action (MoA) groups across early and late generation treatment windows in each season. Prepack insecticides containing two MoAs (e.g., neonicotinoid + pyrethroid) should be only used in the presence of two target pests at economic threshold. Programs A-G were designed for long-maturity potato cultivars that require protection from several CPB generations. Program H was developed for short maturity cultivars (e.g., red and heirloom cultivars) or single generation populations that may not require supplemental applications. newer RR compounds function more ideally when targeting only specific stages; these are often the early larval instar stages. Here, it is important for producers or pest management specialists to scout fields regularly to determine exactly when the majority of individuals within the population(s) are developing through the most susceptible stages. Scouting services together with 20 Spudman.com online phenology tools can increase our understanding of where - and when - CPB populations are reaching different population milestones. It is also important to read the label of each product to learn about the season total maximum product allowable on a potato crop since not all labels contain similar (resistance management) language in terms of guidelines and use directions. As an example, some products limit the number of successive or sequential applications to a single generation within a production season (e.g. no more than two successive applications per crop season), whereas other labels are more permissive and allow for three or four successive reapplications of a single product within a generation.
