Growing oilseed rape in the absence of neonicotinoid seed treatments and the subsequent crop losses from flea beetle and Turnip yellows virus (TuYV) is a major concern looking ahead to this autumn says Philip Marr, OSR expert with Agrii.
“With OSR selling at £250/tonne no-one wants to invest in crops that won’t reach their full potential, and without the necessary crop protection against these threats, either from seed treatments and foliar insecticides, OSR crops will not reach their full yield potential.”
“Flea beetle can destroy establishing crops, however once the crop is established TuYV carried by the aphids Myzus persicae is the biggest threat and can result in as much as 30% yield deduction.”
Up to 72% of Myzus persicae are carrying the Turnip yellow virus, and studies show that if aphids are present, infection is likely to follow.
