Timing Pseudomonas chlororaphis applications to control Pythium aphanidermatum, Pythium dissotocum, and root rot in hydroponic peppers
The ability of the microbial agent Pseudomonas (Ps.) chlororaphis Tx-1 to suppress Pythium aphanidermatum and Pythium dissotocum, and control root rot, was investigated as a function of time of agent application and pathogen inoculation in vegetativestage sweet peppers grown in single-plant hydroponic units. The agent was applied to the nutrient solution at 1 10 CFU/mL and roots were inoculated...
متن کاملEffect of Chitosan on Rhizome Rot Disease of Turmeric Caused by Pythium aphanidermatum
Chitosan was evaluated for its potential to induce antifungal hydrolases in susceptible turmeric plant (Curcuma longa L.). Under field conditions, the application of chitosan (crab shell) to turmeric plants by foliar spray method induces defense enzymes such as chitinases and chitosanases. Such an increase in enzyme activity was enhanced by spraying chitosan (0.1% w/v) on leaves of turmeric pla...
متن کاملstudy of antagonistic mechanisms of bacillus spp. in biocontrol of cucumber root and foot rot caused by pythium ultimum and p. aphanidermatum
abstract a total of 270 bacillus strains were isolated from bulk soil and rhizospheric of cucumber in the tonekabon fields (mazandaran province). antifungal activity of bacillus strains was evaluated against pythium aphanidermatum and p. ultimum using dual culture method. 13 strains with more than 10 mm inhibition zone were selected for further study. morphological, physiological, biochemical a...
متن کاملPotential of Epicoccum purpurascens Strain 5615 AUMC as a Biocontrol Agent of Pythium irregulare Root Rot in Three Leguminous Plants
Epicoccum purpurascens stain 5615 AUMC was investigated for its biocontrol activity against root rot disease caused by Pythium irregulare. E. purpurascens greenhouse pathogenicity tests using three leguminous plants indicated that the fungus was nonpathogenic under the test conditions. The germination rate of the three species of legume seeds treated with a E. purpurascens homogenate increased ...
متن کاملMicrobial Properties of Composts That Suppress Damping-Off and Root Rot of Creeping Bentgrass Caused by Pythium graminicola.
Composts prepared from a variety of feedstocks were tested for their ability to suppress seedling and root diseases of creeping bentgrass caused by Pythium graminicola. Among the most suppressive materials in laboratory experiments were different batches of a brewery sludge compost and a biosolids compost from Endicott, N.Y. Batches of these composts that were initially not suppressive to Pythi...
