IPM case studies: seed potato.

Abstract

This chapter discusses the various aspects of aphid management in seed potatoes, including the advantages of seed certification, the danger of aphids transmitting potato viruses, use of economic thresholds and mathematical modelling. It focuses on the integrated pest management tactics (monitoring aphid flight, chemical, biological and cultural control, and use of pest resistant cultivars) available against aphids of potatoes.

“…However, non-persistent viruses are more difficult to control by pesticide spraying because of their rapid acquisition and transmission properties that enable rapid spread from one plant to another (Radcliffe et al, 2007). But insecticides can only reduce virus transmission if they affect the early stages of plant colonization,i.e.…”

The conflicting relationships between aphids and men: A review of aphid damage and control strategies

“…Decision-making tools for insecticide management are still scarce, aphid-resistant varieties still scarcer and the real use of natural enemies restricted to some glasshouse crops. Maybe the most significant progress is the publication of bulletins monitoring (and sometimes forecasting) aphid population dynamics (e.g., the Aphid Alert Web Bulletin in Minnesota [128], the weekly bulletins from the Scottish Agricultural Science Agency, and many others). These bulletins aim to rationalize insecticide use and promote the adoption of ''improved'' rather than truly ''integrated'' pest management practises [129].…”

Effect of insecticide-treated potato plants on aphid behavior andpotato virus Yacquisition

“…However, persistent viruses can sometimes be controlled by regular monitoring and, when necessary, by spraying their aphid vectors with insecticides . Non‐persistent viruses are more difficult to control through insecticidal spraying because of their prompt acquisition and transmission characteristics, which allow them to spread rapidly from plant to plant . The general consensus is that insecticides cannot prevent the transmission of non‐persistent viruses such as PVY because they would not act fast enough on aphids to prevent them from acquiring the virus and transmitting it to a healthy plant .…”
