Detection of the spectral signature of Phytophthora root rot (PRR) symptoms using hyperspectral imagingremote sensingavocadoseverity detectionhyperspectral imagingPhytophthora root rot (PRR) caused by Phytophthora cinnamomi, is a serious disease and an important constraint to avocado production. The current ...
The mean PAU values for fields in which root rot or blight had been moderate to severe were higher than in fields in which disease incidence had been low or not observed. Miller et al. analyzed the spatial distribution of PAUs by TPL (NQ = 6, NB = 106) and the intensively sampled ...
Phytophthora root rot causes stand reduction, stem decay and, as the name implies, root rot. The disease can hit right after seeding. Seed rot and preemergence damping off can occur. Learn more about this disease in Pioneer’s insect and disease guide.
Phytophthora cinnamomiRands is a highly prevalent phytopathogen worldwide, ranking among the top ten in terms of distribution. It inflicts crown rot, canker, and root rot on numerous plant species, significantly impacting the biodiversity of both flora and fauna within affected environments. With a h...
Mild to extensive feeder root rot was present in all 23 orchards, with trees showing symptoms of citrus decline from nine areas in the Transvaal Province of South Africa. Phytophthora nicotianae and Pythium spp. were isolated from diseased roots and rhizosphere soils in all areas sampled. ...

In 1996, Phytophthora root rot of soyabean occurred at Hongsong and Chongyang in Chungnam province, Korea Republic. The disease has not been reported previously in this country although it has been known to be a serious disease in other countries. Symptoms consisted of yellowing, wilting, defoliat...
All plant parts fromcrown rot,damping-off, collar rot,root diseases,late blight, stem rot, and more. The different symptoms of Phytophthora infection are quite pervasive. The organism causes plants to weaken, collapse and die. Some early warning signs mostly consist of symptoms of drought stress...
can infect almost all parts of the pepper plant and causes different disease symptoms, including root and collar rot and stem, leaf, and fruit blight [4]. Root rot is associated with root darkening and small lesions that can quickly expand to the girdle, and results in the root death [5...
In 2013, soursop trees showing symptoms of root rot were observed in a field in Maceió, state of Alagoas, Brazil. It was isolated Phytophthora sp. which pathogenicity was confirmed in the host seedlings. Morphological and physiological characteristics in carrot-agar modified medium were consistent ...
