Rhizoctonia solani, Fusarium solani, F. oxysporum, and Macrophomina phaseolina were found to be associated with root rott and wilt symptoms of faba bean plants collected from different fieldes in New Valley governorate, Egypt. All the obtained isolates were able to attack faba bean plants (cv. Giza 40) causing damping-off and root rot/wilt diseases. R. solani isolates 2 and 5, F. solani isolate...

The antifungal substances SH-1 and SH-2 were isolated from Streptomyces humidus strain S5-55 cultures by various purification procedures and identified as phenylacetic acid and sodium phenylacetate, respectively, based on the nuclear magnetic resonance, electron ionization mass spectral, and inductively coupled plasma mass spectral data. SH-1 and SH-2 completely inhibited the growth of Pythium ...

Rhizoctonia cerealis and solani are considered to be among the most harmful soil-borne pathogens for crop plants globally. The lack of effective protection requirement minimize use chemical pesticides necessitate need develop alternative protective methods. One such method is resistance breeding against biotic abiotic stresses. Here, we present studies on presence traits in winter wheat genotyp...

chickpea blight caused by didymella rabiei is considered as the most important disease of chickpea in kermanshah province. the disease is seed borne in addition to being persistent on infected residues, secondary infection taking place through pycnidiospores. in laboratory tests, the effects of six fungicides were tested at : 0.01, 0.1, 1.0, 10.0 and 100.0 ?g.a.i.ml-1 csma(chickpea seed meal ag...

broomrape (orobanche spp.) is one of the most serious weed pathogen on many dicotyledonous plants such as tomato, cucumber, melon, tobacco and others. this weed parasite caused serious problem in tomato cultivation fields, especially in north west iran. some isolates of fusarium spp. and pseudomonas fluorescens are known as effective biological agents in biocontrol of this weed. in order to fin...

ABSTRACT The relative contribution of migration of Rhizoctonia solani anastomosis group 3 (AG-3) on infested potato seed tubers originating from production areas in Canada, Maine, and Wisconsin (source population) to the genetic diversity and structure of populations of R. solani AG-3 in North Carolina (NC) soil (recipient population) was examined. The frequency of alleles detected by multilocu...

Rhizoctonia solani is an economically important pathogen of sugar beet (Beta vulgaris L.) causing seedling damping-off, and root crown rot. Cultural practices, partially resistant cultivars, fungicides are among the methods most used to manage R. solani. Penicillium pinophilum, a potential biocontrol agent for was isolated from beet. Our objective evaluate P. pinophilum against AG 2–2 under lab...

After four years of cold storage, dimethachlon resistance of two laboratory-induced resistant Sclerotinia sclerotiorum isolates SCG7 and LA50 declined by 99.5% and 98.9%, respectively, and cross resistance to iprodione and procymidone also declined dramatically. Along with the decline of fungicide resistance, osmotic sensitivity to sodium chloride and glucose decreased tremendously; mycelial gr...
