“Microdochium” seedling blight on wheat is caused by Microdochium nivale (formally known as Fusarium nivale). Seedling blight is invariably caused by fungi carried on the seed and can affect seed vigour and performance. Depending on the season and soil conditions, infected seedlings may be killed before or soon after emergence. Plant establishment can be very poor and may lead to a reduction in grain yield.
Our test, which takes 5-7 days, requires trained mycologists to distinguish Microdochium nivale from other fungi present with results given as the percentage of seed infected. NIAB advises that seedlots with infection levels below 10% do not require a seed treatment. Above 20% infection, growers should consider product choice and likely sowing conditions very carefully.
For customers requiring a more rapid service then our DNA based rapid test is available, which identifies samples above and below the treatment threshold in 2 days.
