Late blight is a disease caused by Phytophthora infestans. The disease can ruin potato and tomato crops in a few days, and early identification is essential in protecting crops. Blight CheckDS is a rapid test to help gardeners detect blight when it first appears and to distinguish blight symptoms from other markings on leaves.
The blight test uses technology identical to that used in the home pregnancy test, with high sensitivity and easy to read results. Each pack contains sufficient materials for five tests.
Even the experts say that the first symptoms of blight are difficult to recognise, but using Blight CheckDS will take guesswork out of the diagnosis. The test is sensitive, specific and reliable.
The Royal Horticultural Society site contains useful information about the control and management of blight.
