Biocontrol of Rhizoctonia solani causing stem canker disease of potato using rhizosphere mold fungi
The aim of the present work is to obtain effective rhizosphere fungal bio-control agents (bio-fungicides) that can antagonize Rhizoctonia solani; the fungal causal agent of stem canker disease of potato (Solanum tuberosum L.) and to improve the growth of the potato plant. A total of eleven different isolates of mold fungi were isolated from the […]
Genetic erosion: assessment of neglected and underutilized crop genotypes in South Western Kenya
The loss of Neglected and Underutilized Species (NUS) of crop results in reduction of the genetic base of the remaining varieties that may have a consequence upon changing environmental and ecological conditions. There is therefore, an urgent need to collect, document, characterize, conserve and utilize the traditional crops and formulate policies that will protect them […]
Repellency and toxicity of three plants leaves extraction against Oryzaephilus surinamensis L. and Tribolium astaneum Herbst.
Screening of plant extracts from wild species of plants for insecticidal properties could lead to the discovery of new agents for pest control. Keeping this in view, the ethanolic extracts of three plants leaves Neem (Azadirachta indica), Mint (Mentha longifolia) and Datura (Datura stramonium) were tested against two stored grain pests viz., Oryzaephilus surinamensis L. […]
Investigation of nursery treatments on sea buckthorn (Elaeagnus rhamnoides (L.) A. Nelson) seed germination in the field
This study was conducted for the first time in nursery treatment in order to pioneer forest trees of the species Elaeagnus rhamnoides and also to determine the effects of different treatments on seed germination in Iran. This species is resistance for plantation. Seeds originating from Qazvin province were placed in the nursery. Treatments comprised three […]
Fungal pathogens associated with grapevine wood lesions in Algeria
A field survey was conducted in Algeria to assess the state of dieback in some vineyards and identification the fungal pathogens associated with necrotic wood lesions. Field surveys conducted during spring seasons in 2006 and 2012 revealed that an average disease incidience was 25 % , the indice of disease severity varied of 0.5 – […]
Arsenic concentrations in commercial fish from freshwater and saltwater
Research was performed to investigate the concentration of arsenic in muscle and liver of fish species from freshwater, Barbus luteus, Aspius vorax, Cyprinion macrostomus in Karoon Rivers and saltwater, Liza dussumieri, Liza klunzingeri, Liza macrolepis, Scomberomorus commerson, Otolithes ruber, Scomberomorus guttatus, in Persian Gulf, Iran. Arsenic levels in muscles of seaport fish were high in […]
Comparison of aerial and underground carbon sequestration potential of Stipa barbata in Fasham Pastures, Iran
Rangelands play an important role in the carbon cycle. Although their ability to absorb CO2 from the atmosphere could help offset human influence on climate change, there are many other ecological benefits associated with sequestering carbon on rangelands. Iran’s rangelands have carbon sequestration capability by compatible species with the area. However, little information is available […]
Impacts of grazing ungulates on vegetation and soils in areas closer to water holes in serengeti plains, Tanzania
Impacts of grazing ungulates on vegetation and soils in areas closer to water holes in Serengeti plains were studied between September 2004 and December 2004. Grass cover, percentage of grass grazed and soil characteristics closer to water holes and those as far as 4 km from water sources were evaluated. Grazing was found to be […]
Contamination of anti malarial plants by Lead and cadmium in cotonou, Republic of Benin
In order to investigate the level of contamination with toxic heavy metals in anti-malarial plants sold in the markets of Cotonou, some anti-malarial plants were selected through an ethno-botanic survey by using the ATRM (Triple Purchase of Healing Plants) a method elaborated in Togo. Out of 35 species of plants listed as anti-malarial, 5 were […]
