Aphid(various species)


General Description

Damage: Aphids can cause premature senescence and reduce yields, especially large populations. But the main economic impact of aphids on potatoes is virus transmission, especially Potato Leafroll Virus (PLRV) and Potato Virus Y (PVY). Green peach aphid and potato aphid are the most common aphid species in potato fields, but other aphids can spread viruses while passing through in search of more suitable hosts.  

Scouting: Potato growers should monitor fields for aphids often to identify early infestations. Aphids can reproduce rapidly and large infestations can be difficult to control with a single insecticide application. 

Control: Some aphicides are better than others at limiting spread of PVY. Many that work via ingestion kill aphids too slowly to prevent spread; an exception is selective feeding blockers that kill slowly but stop feeding within hours. Contact insecticides can be useful to knockback aphid populations, but many do not have long enough residual activity or coverage of new growth to prevent migrating aphids from spreading PVY between applications.

2 Efficacy ratings denote the relative ability of a pesticide to control its target. The ratings are E = excellent, G = good, F = fair/suppression; P = poor, and ND = no data. Efficacy ratings are based on the inherent toxicity of the pesticide against its target, the likelihood that the target will contact or ingest the product as applied, duration of impact on the target, and undesired effects, such as negative impacts on natural enemies that could lead to future pest outbreaks.
3 Rate per acre per application. Refer to the product label for maximum use rate per season.
