News on Phytophthora

Idaho potato fields looked good as of early July as plants closed in over rows, signaling the tubers are preparing to grow strongly amid the hot-day, cool-night march toward harvest.

Victoria - a popular local potato variety in Uganda - is extremely susceptible to potato Late Blight disease, but a resistant GM version of this variety has been developed.
With testing almost complete, it is up to the government biosafety regulatory authorities in Uganda.

Tubers were the talk of the town in Cusco, Peru during the week of May 27, when the 10th World Potato Congress (WPC) and the 28th Congress of the Latin American Potato Association (ALAP) were held together for the first time.

Jean Ristaino, a professor at North Carolina State University with emphasis in research on Phytophthora infestans, reported on a late blight look-alike from tomato and potato in North Carolina.

Potato growers in Idaho will now have the opportunity to learn about the presence of damaging fungal pathogens much earlier, thanks to the efforts of research staff at the University of Idaho. The research team, led by James Woodhall, has placed 14 spore samplers in potato fields across the Snake River Valley.

Potato cultivation in the highlands of Indonesia is plagued by a number of pests, including Potato Cyst Nematodes and Phytophthora infestans. Dutch experts help their Indonesian counterparts to find the right approach for control.

The EuroBlight project is examining the ongoing evolution of the potato late blight pathogen (Phytophthora infestans). In 2017, almost 1500 samples from 16 countries in Europe were genotyped. The results indicate that new clones continue to spread.

Late Blight control strategies in the United Kingdom will have to change this season if potato growers are to combat the spread of a new aggressive, fungicide-insensitive/ resistant strain of the disease, leading agronomy firm Hutchinsons says.

Benjamin 'Benjy' Firester, 18, of New York City, won the top award in the Regeneron Science Talent Search 2018 with a mathematical model that uses disease data to predict how weather patterns could spread late blight spores.

Tanzania has excelled in experimental trials of high yielding and disease resistant potato varieties under a climate smart agriculture programme aimed to improve food security.

Agrico presented its new generation potato varieties with high resistance to late blight (Phytophthora Infestans) at Fruit Logistica. On the first day of the fair, General Manager Jan van Hoogen explained the meaning of these new varieties.

Identification of the receptor for Cytolisin - the killer toxin of Phytophthora infestans - opens door to biological methods to protect potatoes and selective, biological herbicides as alternative for glyphosate

Although the full harvest is not in the stores yet, the North-Western European Potato Growers (NEPG) estimates the actual harvest at 28.9 million tons for the 5 countries. This is more than the estimate of last September.

A genetically-modified (GM) Maris Piper designed to resist the devastating plant disease late blight has worked “brilliantly” during the first year of field trials, according to scientists of The Sainsbury Laboratory (TSL)

For the current European potato harvest, the North-western-European Potato Growers (NEPG) estimate the total potato production at 27.9 million tons for the five NEPG countries (Belgium, Germany, France, The Netherlands and Great Britain). This is up 13.5 percent compared to last season.

Op basis van proefrooiingen en praktijkresultaten verwacht de NEPG een totale oogst van 27,9 miljoen ton aan consumptieaardappelen in Noord-west Europa. Dat is 13,5% hoger dan vorig jaar.

The breeders of Solynta have succeeded in making potato plants insusceptible to the dreaded potato disease Phytophthora infestans, using their revolutionary hybrid breeding technique.

The Dutch company Solynta has developed a potato variety that is resistant to late blight (Phytophthora Infestans). As a result, it could greatly reduce the use of pesticides in agriculture.
