The very early discovery of a new potato blight strain in Britain doesn't mean that spray programmes will have to change this year, agree researchers and agronomists.
Found for the first time in the UK last year, the new blight strain 33_A2 (known as Green 33) is on the increase in The Netherlands, where it accounts for about 20% of the blight population.
The fact that it has made its way to the UK shouldn't alarm growers too much, believes David Cooke of the James Hutton Institute.
