The response of pea (Pisum sativum) genotypes to ascochyta blight disease and the effect of disease severity on yield components were evaluated in a 4-year trial under field conditions. Peas were inoculated with Ascochyta pinodes, the anamorph of Mycosphaerella pinodes, or with Phoma pinodella separately and with a mixture of both species. Mean infection ratings of all inoculation treatments we...

Effects of climate change on productivity of agricultural crops in relation to diseases that attack them are difficult to predict because they are complex and nonlinear. To investigate these crop-disease-climate interactions, UKCIP02 scenarios predicting UK temperature and rainfall under high- and low-CO(2) emission scenarios for the 2020s and 2050s were combined with a crop-simulation model pr...

The fungal pathogen Phoma clematidina is used as a biological agent to control the invasive plant species Clematis vitalba in New Zealand. Research conducted on P. clematidina as a potential biocontrol agent against C. vitalba, led to the discovery of two perithecial-forming strains. To assess the diversity of P. clematidina and to clarify the teleomorph-anamorph relationship, phylogenetic anal...

Avicennia marina (Tamil : Alai : Alai atti) : Avicennia marina is the dominant mangrose species in Karankadu and accounts for about 95% of the vegetative cover plant in Indian Sub-continent was investigated for endophytic mycoflora as a possible source of bioactive secondary metabolites. Being salinity resistant, this species dominate most mangrove area of the country including karankadu. Four ...

Feeding of fluorinated benzoic acids to fermentations of a Phoma sp. resulted in the biosynthesis of a series of novel fluorinated squalestatins. The feeding studies, isolation, structural elucidation and biological activities of these compounds are reported.

Fungal root endophytes obtained from natural vegetation were tested for antifungal activity in dual culture tests against the root pathogen Gaeumannomyces graminis var. tritici. Fifteen isolates, including Acremonium blochii, Acremonium furcatum, Aspergillus fumigatus, Cylindrocarpon sp., Cylindrocarpon destructans, Dactylaria sp., Fusarium equiseti, Phoma herbarum, Phoma leveillei, and a steri...

Mal secco disease is a vascular pathogen causing serious damage and death to the host, particularly lemon, in Citrus and related genera, in Mediterranean countries and the Black Sea region. So far, however, it is unknown in Spain, Portugal and Morocco, as well as other major Citrus-growing regions of the world. Symptoms include red strands visible in stem xylem as well as veinal chlorosis, wilt...
