The cucumber (Cucumis sativa L.) is often subjected to several fungal diseases. Rhizoctonia solani-induced damping-off and root rot are the most common diseases reported from commercial greenhouses of eastern area Saudi Arabia. objective current study explore antagonistic activity four Trichoderma species against R. solani in vitro vivo. Ten isolates (eight belonging AG-4 two AG-A AG2-1) were s...

As a polyphagous organism, Rhizoctonia is one of the most infectious soil-borne pathogens for many plant species. To reduce this threat to plants and hence provide good quality products end-user, it crucial develop sophisticated environmental friendly protection methods. One such method biological control using beneficial agents, e.g., microorganisms as bacteria fungi, but also mites or insects...

Rhizoctonia solani causes economically important root and hypocotyl diseases in common bean throughout the world. Root health is a vital factor in plant development and root diseases would negatively influence water and nutrient uptake as well as cause direct stand reduction and root rot damage to the crop. An efficient common bean screening method to evaluate damping-off and early root/ hypoco...

HOWELL, C. R. 1978. Seed treatment with L-sorbose to control damping-off of cotton seedlings by Rhizoctonia solani. Phytopathology 68:1096-1098. The keto sugar, L-sorbose, inhibits hyphal extension and accumulate in the soil. When applied to seed in crystalline promotes profuse branching in Rhizoctonia solani. When form with sticker, L-sorbose is highly water soluble and may applied to cotton s...

A two-step method was developed to evaluate potato resistance to black scurf caused by Rhizoctonia solani. Tuber piece inoculum was first conducted in the laboratory, which was also first reported in this study. After inoculation with pathogen discs and culture for 48 h, the necrotic spots on the inoculated potato pieces were generated and measured by the crossing method. Further evaluation was...

Rhizoctonia muneratii ATCC 13247 was capable of catalyzing the conversion of 25-hydroxycholesterol to the 3-oxo-4-ene. Hydroxylation at the 6alpha and 6beta positions with the concomitant 3-oxo-4-ene transformation was also observed. The addition of Triton X-100 to the growth medium immediately before steroid addition selectively prevented the appearance of the respective 6alpha-hydroxylated pr...
