death are a disease complex known as peach tree short life (PTSL) and Armillaria root rot ( Miller, 1994 ; Savage and Cowart, 1942 ). Peach tree short life is reportedly caused by a predisposition of trees to cold injury, bacterial canker ( Pseudomonas

, 1996 , 1997a ; Smith, 1960 ; Snyder et al., 1959 ). After infection, the fungus causes both black root rot diseases and seedling damping-off. In Canada, this pathogen causes black root rot on carrot ( Daucus carota ) ( Punja et al., 1992 ) and

Plant loss resulting from root rot-causing fungal pathogens is a significant problem for ornamental and vegetable producers. The most common method of control for these diseases involves the use of chemical fungicides as substrate drench treatments

preplant soil fumigation. Unlike most root pathogens, which produce spores that lie dormant in the soil (e.g., Phytophthora ), Armillaria persists in its vegetative stage—mycelium—within woody roots left in the soil after clearing infected trees

table beet quality and yield is Rhizoctonia root and crown rot caused by the fungus Rhizoctonia solani Kühn (Abawi et al., 1986; Natti, 1953 ; Pethybridge et al., 2018 ), which renders table beet roots unmarketable. Currently, there are few chemical

containers that might be contaminated with pathogens from previous infected plants grown in them. Personal observations (R.G. Linderman) in recent years have shown that the root rot pathogens T. basicola and Pythium spp. can survive in used plug flats

causing significant damage to leaf tissue ( Copes and Blythe, 2009 ). Because the objective of the study was pathogen control efficacy, a level of acceptable leaf damage was determined based on reasonable expectations without documenting the effect on root

Vegetable growers need alternative strategies to manage the pathogen responsible for phytophthora blight. In this study, we provide evidence that a commercially available biochar amendment can decrease P. capsici soil populations and reduce percent root

selections are F 1 hybrids between wild North American red raspberry ( Rubus strigosus Michx.) and ‘Tulameen’, which were initially selected for their combination of outstanding resistance to root rot caused by Phytophthora rubi [(Wilcox & Duncan) Man in

Diseases caused by Phytophthora species are among the most damaging to greenhouse and nursery-grown horticultural crops ( Jones and Benson, 2001 ; U.S. Department of Agriculture, 2009 ). These pathogens cause damping-off diseases, root rot, stem
