Phytophthora is a difficult problem to deal with. Especially for organic farming where no synthetic crop protection products may be used, which is why Bionext has labeled a first generation of resistant varieties as ‘Robust’. This sounds promising, but there is still a great danger in this approach. The first generation of resistant varieties is based on only one (solo) resistant gene, which means that there is only one lock on the Phytophthora door while Phytophthora is a master burglar.

WUR launches major nematodes research project
Climate change and genetic selection have brought root-knot nematodes further north in Europe and made cyst nematodes more difficult to control. These emerging parasites threaten major crops such as potato. To get a clear picture of the proliferation of novel nematode species and populations and to find appropriate and sustainable solutions to these problems, WUR…
Origin of novel broad resistance to late blight found in wild potato relatives
To understand the mechanisms of late blight resistance of potatoes better, researchers of Wageningen University & Research together with their colleagues in Tübingen and Norwich have taken an important step. Their research has been published in the renowned scientific journal Science.
Specialists present opportunities of late blight resistant biotech potatoes
On Tuesday March 21, 2023, Dr. Marc Ghislain and Dr. Eric Magembe of the International Potato Center (CIP) will be presenting the World Potato Congress (WPC) webinar on the deployment of late blight resistant biotech potatoes in Africa.
Late blight (Phytophthora infestans)
In regions where potatoes are grown year-round, such as in tropical highlands, there are always spores of the disease present to infect newly emerging crops. In temperate climates in spring, the sources of inoculum are seed tubers, dumps and cull piles, volunteer plants and asexual zoosporangia or sporangia (single sporangium) blown from elsewhere by the…
