Acquisition and transmission of PVY by these aphids occurs within 15 to 30 seconds, which is much faster than contact insecticides are able to kill the aphids. Thus, contact insecticides are of limited effectiveness in PVY management. However, use of insecticides to control aphids in nearby crops or natural areas can help reduce PVY spread by reducing the number of transient aphids moving through the potato crop. Use of crop oils also has potential to reduce in-season movement of PVY, but effectiveness will likely be dependent on when applications are initiated, frequency of applications, method of application (air vs. ground), and type of irrigation (pivot vs. other). Crop oils must cover all plant surfaces, be re-applied to new growth and after rain or irrigation events, and be applied continuously from emergence to vine desiccation in most seed production areas of the U.S. Use of crop borders is yet another tool that has been explored for decades. Research has shown that for small plots, crop borders can effectively reduce in-season spread of PVY. Aphids that alight on the crop border before entering the potato crop will probe the border plants and cleanse their mouthparts of virus before moving into the potato crop. The utility of borders decreases as field size increases. None of these management options by themselves offers a silver bullet to the problem, and they may not be practical for all situations. Outcomes from ongoing research will help to refine these tools and identify additional strategies that can help combat PVY. However, even the most effective management strategies can be overwhelmed. A grower who plants seed, whether purchased or saved, with high PVY levels places all other growers in the area at risk. This last issue is why PVY management really is a community effort and needs a wide net to capture all possible advantages of the different management strategies.
