The potentials of poultry, farmyard and refuse dump manures for management of Phytophthora root rot on sweet peppers, Capsicum annuum was evaluated in pot experiments under controlled conditions. Five week-old seedlings of pepper varieties were transplanted into heat sterilized soil amended with poultry, farmyard and refuse dump manures at 2, 4 and 8 tons/ha. The pots were arranged in complete ...

root rot disease of broad-bean caused by fusarium solani is a serious disease of this crop. due to high cost and difficulty of the disease control, interaction between root nodulating bacteria and fusarium. solani were evaluated to use for disease management. broad-bean root nodulating bacteria were isolated and their interaction with f. solani was investigated in culture medium in a completely...

Aphanomyces euteiches Drechs. causes economically important root rot diseases of several legume species when wet soil conditions prevail. This soilborne oomycete pathogen causes severe root rot damage to pea (Pisum sativum L.), alfalfa (Medicago sativa L.), snap bean (Phaseolus vulgaris L.), and red clover (Trifolium pratense L.) (12,21,22,24,25,29). A. euteiches was first described as an impor...

Accurate delineation of root rot infestations is necessary for site-specifi...

Phytophthora cinnamomi causes a severe root rot in avocado, Persea americana. Breeding tolerant rootstocks is thought to be the most promising method for phytophthora root rot disease control but breeding avocado is challenging. The avocado flowering syndrome (synchronous protogynous dichogamy), combined with high flowering and low fruit set, render controlled pollination exceedingly difficult....

We show that the disease tomato foot and root rot caused by the pathogenic fungus Fusarium oxysporum f. sp. radicis-lycopersici can be controlled by inoculation of seeds with cells of the efficient root colonizer Pseudomonas fluorescens WCS365, indicating that strain WCS365 is a biocontrol strain. The mechanism for disease suppression most likely is induced systemic resistance. P. fluorescens s...

Phytophthora root rot causes extensive damage to feeder roots of avocado. If uncontrolled, it results in a progressive decline in tree health and the eventual death of the tree (12, 14, 15). Phytophthora root rot is a major factor limiting avocado production world wide. Effective control of Phytophthora root rot of avocado has been achieved with fosetyl-al (Aliette® Rhone-Poulenc, aluminum tris...

Methods for the evaluation of root rot disease in sugarbeet caused by pathogenic fungi historically have relied on visual assessment. In an initial attempt to develop complementary means to detect and quantitate root rot disease caused by Aphanornyces cochlioides, antiserum was produced in rabbits that had been immunized with a cell-wall preparation of this organism. Specificity tests using enz...
