Pesticide Tables for Potato Pests Tables 1-3 present nearly exhaustive lists of insecticides and biocontrol agents that are registered to control arthropod pests of potatoes in the PNW. Some of these products provide better control than others. Tables 1 and 2 are lists of conventional pesticides, with Table 1 being products with a single active ingredient and Table 2 being mixed products commonly known as package mixes. Most package mixes have a broad spectrum of control, but if over-used can contribute to outbreaks of certain pests such as aphids and spider mites, and also increase the risk of insecticide resistance due to over-application of a single mode-of-action such as the neonicotinoids (IRAC 4A). Table 3 lists many of the available products that are either biocontrol microbes, approved for organic use, or are not directly insecticidal. The latter category includes some of the oil sprays, which are most effective in interrupting virus transmission by aphids, as opposed to killing insects outright. Table 1.
