Researchers at Michigan State University used a fluorescent isolate of the broad host range pathogen, Phytophthora capsici, to develop a high-throughput, microtiter plate assay for replicated quantification of pathogen growth on plant tissue in real time. This method, which can detect pathogen growth prior to development of symptoms, can assist with screening for disease resistance, mapping of resistance loci, testing efficacy of control measures, or elucidation of fundamental host-pathogen interactions.
Phytophthora
The pathogen Phytophthora capsici causes Phytophthora Crown Rot, Phytophthora blight, and Phytophthora fruit rot.

Abnormally Wet Fall Challenging for Alabama Pumpkin Producers
ONvegetables VCR | Sept. 10, 2020
ONvegetables reports that wet soil conditions are conducive to infection by Oomycetes such as Phytophthora which can lead to extensive damage in the field, and can lead to storage rots. Workers harvesting pumpkins and squash with Phytophthora infections should sanitize their hands after handling infected fruits before handling uninfected fruit. Management of Phytophthora infestation in cucurbit fields requires a long (4-5 year) rotation.”
Phytophthora roundtable discussion | GLVPN
How can growers living with this devastating disease of cucurbits, peppers and tomatoes produce a harvestable crop? Dr. Smart works on the “Phytophthora farm” at Cornell University, land which is dedicated to researching solutions growers can use to deal with this disease.
August 19, 2020 Vegetable Production Updates | MSU Extension
Squash, cucumbers, and pumpkins experienced disease pressure from plant viruses, powdery mildew, fusarium, and phytophthora in Michigan during the week of August 13 to 19, 2020.
New photo gallery: Pythium fruit rot in Cucurbits | Cornell Vegetable Pathology
Fruit rot caused by Pythium species can be confused for that caused by Phytophthora capsici, another oomycete pathogen, because they both produce white growth on affected fruit.
