Ascospore dimensions of eight populations of Leptosphaeria maculans and L. biglobosa, causal agents of rapeseed blackleg disease, isolated from debris of rapeseed (Brassica napus) and wild mustard (Sinapis arvensis) were evaluated in Mazandaran and Golestan provinces. Results of ANOVA indicated significant differences in the dimensions of ascospore...

Nitric oxide (NO) is an important signaling molecule in a biological system as the molecule is involved in various aspects of plant growth and responses to both abiotic and biotic stresses. Abiotic stress is caused by drought, high or low temperature, high salinity, heavy metals and oxidative stress while biotic stress is caused by pathogens and he...

Chitosan has a broad spectrum of unique biological activities, including its ability to induce resistance to viral infections in plants, inhibit viral infection in animal cells .The size of its molecule varies widely and is characterized by either the mean degree of polymerization or the mean molecular weight of the polymer. Chitosan obtained by al...

Thirteen isolates of Pseudoperonospora cubensis, the causal agent of downy mildew, were collected from cucurbit fields in five states of the western part of Peninsular Malaysia during its growing season between November 2008 and March 2009. The host range of these isolates was determined previously using leaf disc assay and the results indicated th...

A total of 29 isolates of Pseudoperonospora cubensis were collected from various cucurbit farms in West Malaysia. Sporangia of 13 isolates had the ability to germinate at 14°C and were used for host range (pathotype) study using leaf disc assay on a set of twelve cucurbit cultivars. Twelve different pathotypes of P. cubensis were determined and thi...

In December 2008, infected leaves of Trichosanthes cucumerina were observed on commercial cucurbit farms located in Pontian, Johor (south of West Malaysia). Bright yellow and small necrotic lesions were observed on the adaxial surface of the leaves, whereas sporangiophores were observed on pale yellowish brown-to-brown lesions on the abaxial surfac...

During 2007-2008, Leptosphaeria maculans and L. biglobosa the causal agents of rapeseed blackleg were identified based on leaf and stem symptoms and morphological characteristics (teleomorph and anamorph) in Mazandaran and Golestan provinces. Among 49 Leptosphaeria isolates, 43 isolates were obtained from rapeseed (on leaves, stem and debris) in si...

-The soybean cyst nematode (SCN), Heterodera glycines, found in most soybean growing regions in the world, is considered the most economically damaging pathogen of soybean worldwide. A survey conducted in the northern provinces of Mazandaran and Golestan, the main soybean-producing areas in Iran, revealed SCN was widespread in different localities...

Canola/rapeseed (Brassica napus L.) is a new crop in Iran, grown since 1996. In 2006, 180,000 ha were planted. During the same year, leaf and upper stem lesions (3) were observed on cv. Hyola 401 at rosette and flowering stages in the Gorgan Province in northern Iran. Field disease incidence ranged from 1 to 40%. Several isolates from stem lesions...

During recent years oilseed rape (Canola-Brassica napus) cultivation has gained an importance in different geographical zones in Iran. Viral diseasesof economic importance have been reported to infect canola crop and causes considerable damage to the crop and economic losses to the farmers. During different surveys, various and common symptoms o...

Soybean (Glycine max (L.) Merr.) has been increasing in importance and acreage for the past 5 years in Iran and is now planted on approximately 108,000 ha. Previous surveys in Iran of viruses infecting soybean failed to identify Bean pod mottle virus (BPMV), but the incidence of other common viruses of soybean in the field has been reported (1). Du...
