Western flower thrips (WFT) and the tospoviruses they vector continue to be a major problem on floriculture crops around the world. While there have been some new, effective pesticides that have come to market that provide thrips control, these must be used with caution and care to preserve their effective field life. As with many arthropod pests in the greenhouse, WFT can readily develop resistance to pesticides. In fact, resistance by WFT to more than 20 pesticides (from all classes and including spinosad) and in six different countries has been documented. As growers struggle to maintain control of WFT, the more techniques in the pest management toolbox, the greater the chances for effective control. Management techniques or tools with the highest probabilities of generating acceptable levels of suppression of WFT and other arthropod pests include applications of reduced risk insecticides, releases of effective natural enemies, and total crop management (through the manipulation of agronomic inputs). With more ‘effective’ materials, growers will be able to rotate products, thus prolonging the effective field life all these insecticides. In addition, if new materials fit the profile of a reduced risk pesticide, there will be less problems associated with worker health and safety, and environmental contamination. In addition, such products may be compatible with natural enemies, thus allowing growers to use multiple tactics to control WFT and other pests. Management of agronomic inputs (ex. fertilizers) affects the nutritive qualities of plant tissues and hence may also be used to shift pest population dynamics that enhance the grower abilities to effectively suppress pest densities to acceptable levels. From the research propose, we intend to develop information that can be used by rose growers in the US (both potted and cut) and Colombia (cut) to advance their pest management strategies. In addition, the research on reduced risk pesticides, biological control and crop nutrition have broad applicability beyond roses and can be extrapolated to many other floriculture crops.
