Late blight, caused by Phytophthora infestans, is the most important disease in potato production. Under favourable conditions the pathogen can destroy the potato foliage very rapidly and cause tuber blight. To avoid infection of the foliage, fungicides are frequently sprayed onto the crop. In the Netherlands, in some years up to 15 sprays are necessary to prevent the crop from infection by the pathogen. A field experiment was conducted at the Wageningen University, Lelystad facility to evaluate the performance of the MagrowTec system vs conventional spraying methods in the efficacy of fungicide spray programs in their control of potato late blight. This paper is a condensed version of the report that was completed by Wageningen University.
