Dry edible beans are a vital food source in Mozambique, East Africa—one that alleviates hunger and malnutrition adds value to the economy. In recent years, root/crown rot (RCR) pathogens have emerged as limiting constraints dry bean production. Not much has been characterized concerning causal agents of RCR Mozambique. The purpose this study was identify primary pathogen(s) associated with samp...

the root endophytic fungus, piriformospora indica, colonizes roots of a large number of plant species including cereals and brasicaceae. there are several reports indicating that p. indica protects roots from different path-ogens. in the present study, rice plants were pre-inoculated with p. indica and were subsequently infected with fusarium proliferatum, as the causal agent of root rot and cr...

Two methods to induce a symptomless infection of crown rot (Phytophthora cactorum) in stolons of three strawberry (Fragaria×ananassa) cultivars were evaluated. Spraying a 10−4 ml zoospore suspension was the most effective method, producing a mean infection rate of 12%. Meristem cultures were subsequently established from all of the inoculated stolons and tested eight weeks later for the presenc...

plants showing root and crown rot were collected from 48 bean fields in the khuzestan and markazi provinces during 2005-2006. using specific primers (fsphr/fsphf) for these forma specialis, three isolates were identified as f.s. f.sp. phaseoli. conidial suspension of one of these isolates were irradiated (in a 60co- gamma cell with activity of 2500 curi and 0.38 grey per second dose rates) with...

Abstract Utilization of biocontrol agents is a sustainable approach to reduce plant diseases caused by fungal pathogens. In the present study, we tested effect candidate fungus Aureobasidium pullulans (De Bary) G. Armaud on strawberry under in vitro and vivo conditions control crown rot, root rot grey mould Phytophthora cactorum (Lebert Cohn) Botrytis cinerea Pers, respectively. A dual plate co...

In vitro studies with Trichoderma spp., soil-borne fungal antagonists, demonstrated that a number of isolates produced volatile and non-volatile metabolites capable of inhibiting the growth and sporulation of several soil-borne plant pathogenic fungi. Microscopic observations showed that T. harzianm and T. viride, isolated from soil samples from Ahwaz and Karaj, adversely affected the myce...

Chestnut ink disease represents a great risk for chestnut (Castanea sativa Mill.) in all regions of chestnut production of Europe and North America. Induced by soil borne oomycetes, Phytophthora cinnamomi and P. cambivora, both parasites infect the root system and cause root and collar rot resulting in dieback, decline and finally, the death of infected trees. There are no single control measur...
