Section Prostrata of the genus Verticillium was introduced by GAMS (1971) to separate verticillium-like anamorphs of the Clavicipitaceae from other species of the genus that were known or supposed to have affinities with other families of the Hypocreales. Other sections of Verticillium were subsequently described by GAMS & VAN ZAAYEN (1982). MESSNER et al. (1996) showed that the most important ...
background : mosquitoes transmit serious human diseases, causing millions of death every year. vector control is facing a threat due to the emergence of resistance to synthetic insecticides. insecticides of botanical origin may serve as suitable alternative biocontrol techniques in the future. nine different locally available medicinally important plants suspected to posse larvicidal property w...
The soil-borne gram-positive bacteria Aneurinibacillus migulanus strain Nagano shows considerable potential as a biocontrol agent against plant diseases. In contrast, A. migulanus NCTC 7096 proved less effective for inhibition of plant pathogens. Nagano strain exerts biocontrol activity against some gram-positive and gram-negative bacteria, fungi and oomycetes through the production of gramicid...
The brown spot disease is one of the seed-borne diseases of rice, found in the all stages of its growth from nursery to farm. It causes qualitative and quantitative damage on rice. Therefore, some studies carried out on the different aspects of this disease and the reaction of some cultivars of rice against the pathogenic fungous agent of the diseases. To do so, 120 isolates, isolated from plan...
The most exploited and widely used fungal biocontrol agents in agriculture for the management of plant diseases caused by a wide spectrum of fungal pathogens (Sharma et al., 2014). Trichoderma is among the most exploited fungal biocontrol agents in agriculture for the management of plant diseases caused by a wide spectrum of fungal pathogens (Mathivanan et al., 2000). Production of extracellula...
the following question poped up: is there any relationship between iranian high school efl learners reading comprehension and listening comprehension? then the following null hypothesis (ho) was developed to the test the above, mentioned question. "there is no relationship between high school efl learners reading comprehension and listening comprehension. for nearly 16 weeks, the experimental g...

Charcoal rot caused by Macrophomina phaseolina is one of the most important soil borne diseases with a broad host range including bean, which annually brings a significant damage to this plant. Biological control of charcoal rot is very important because its chemical control harms the environment, microflora and soil fertility. Chemical control of charcoal rot is also difficult and sometimes in...
we commence by using from a new norm on l1(g) the -algebra of all integrable functions on locally compact group g, to make the c-algebra c(g). consequently, we find its dual b(g), which is a banach algebra so-called fourier-stieltjes algebra, in the set of all continuous functions on g. we consider most of important basic theorems about this algebra. this consideration leads to a rather com...
the purpose of this study was to examine the english language needs of medical students at tehran university of medical sciences . analysis of the needs took place for three groups: 320 undergraduate students, 30 postgraduate students and 20 university instructors. a triangulation approach to collect data was used in which a combination of the quantitative (using the questionnaires) and qualita...
