Paulownia species are fast growing trees native to China, which being grown in managed plantings several European countries for the production of wood and biomasses. In 2018, wilting, stunting, leaf yellowing, collapse, as a consequence root crown rot, were observed around 40% 2-year-old planting elongata × P. fortunei Calabria (Southern Italy). Two Phytophthora consistently recovered from root...

Different species of Phytophthora cause serious and economically important soilborne diseases of citrus throughout the World. Tree and crop production losses occur from damping-off of seedlings in the seedbed, root and crown rot in nurseries, foot rot and fibrous root rot, and brown rot of fruit in groves. Foot rot results from infection of the bark near the ground level producing lesions on th...

Charcoal rot of sorghum causedby the fungus ~acrophorfdna phaseolina is a root andstalk rot disease of great destructive potential in most sorghum-growing regions. Improved, highyielding cultivars under good management tend to be very susceptible to the disease. M. phaseolina is a common soilborne, nonaggressive, and plurivorous pathogen that attacks plants whose vigor has been reduced by unfav...

Abstract Utilization of biocontrol agents is a sustainable approach to reduce plant diseases caused by fungal pathogens. In the present study, we tested effect candidate fungus Aureobasidium pullulans (De Bary) G. Armaud on strawberry under in vitro and vivo conditions control crown rot, root rot grey mould Phytophthora cactorum (Lebert Cohn) Botrytis cinerea Pers, respectively. A dual plate co...

Search for methods of control or eUmination of the cotton root rot fungus (Phymatotrichum omnivorum (Shear) Dug.) in the alkahne soils of the Southwest has already continued for half a century. The literature involved has recently been reviewed by Rea (16)^ and by Streets (17). Nearly all of these discussions have been from the viewpoint of plant pathology or agronomy. Garrett (7) included this...
