Susceptibility of Garden Plants to Phytophthora Root Rot

Plant Disease, 2021
Phytophthora root rot (PRR) is a serious disease of horticultural, forest, and ornamental plant species caused by species of the oomycete genus Phytophthora. Their wide host range makes the choice of resistant plants in the management of the disease difficult. We used the Royal Horticultural Society diagnostic dataset of PRR records from U.K.

Economic comparison of phytophthora root rot control methods

Crop Protection, 1994
Abstract The economics of strategies for control of root rot on chile (or chilli) peppers ( Capsicum annuum ) caused by Phytophthora capsici were analysed. The strategies investigated were alternate-row irrigation, every-row irrigation and chemical treatments with alternate-row irrigation.

Phytophthora Root and Crown Rot of Franklinia Trees

Arboriculture & Urban Forestry, 1980
AbstractA root and crown rot leading to wilt ofFranklinia alatamahahas become an increasingly important disease in nursery production of this plant. The pathogenicity ofPhytophthorasp. isolated from diseased roots and crown cankers was shown in inoculated, rooted cuttings and 1 to 3 year-old, container-grown plants. The disease has not been observed in

Excess Soil Water and Phytophthora Root Rot Stresses of Phytophthora Root Rot Sensitive and Resistant Alfalfa Cultivars1

Agronomy Journal, 1985
AbstractThe adaptation of alfalfa (Medicago sativa L.) to well‐drained soil has limited its range of culture. The poor performance of this crop in wet soils has often been attributed to the effects of Phytophthora root rot (PRR). However, excess soil water itself may reduce alfalfa growth.
