Researchers are looking at ways to improve systems for monitoring and managing the rising threat of BYDV in cereal crops. CPM finds out their conclusions so far and the work that still needs to be done to better understand the many factors that could be used to manage this complex disease. Predators are highly susceptible to autumn applied pyrethroids. By Lucy de la Pasture Controlling the spread of plant viruses has just got harder with the demise of neonicotinoid seed treatments putting the emphasis back on pyrethroids for vector control. Oilseed rape growers have been denied neonics for a while, but until this season sugar beet and cereal growers have been able to benefit from the protection they offered. This autumn the importance of BYDV rises up the agenda and researchers have been looking at ways to mitigate the risk the disease poses to cereal crops. With moderate levels of pyrethroid resistance already present in one of the aphid species that carry the virus, a more integrated approach is being sought to avoid driving selection for resistance by avoiding unnecessary spraying. Yellow sticky traps can be placed in crops, horizontally to the ground, to catch aphids as they’re…
