Strawberry (Fragaria×ananassa) is one of the most important berry crops in the world. Root rot of strawberry caused by Rhizoctonia spp. is a serious threat to commercial strawberry production worldwide. However, there is no information on the genetic diversity and phylogenetic status of Rhizoctonia spp. associated with root rot of strawberry in Australia. To address this, a total of 96 Rhizocto...

A root rot disease is the most important factor limiting commercial production of vanilla [Vanilla fragrans (Salisb.) Ames] in Puerto Rico. According to a survey of growers in 1945 (1), the disease was responsible for 40% to 50%o death of vines. In 1927 the causal organism was identified as Fusarium batatatis var. vanilae, Tucker (5). The disease usually becomes more pronounced during the third...

The influences of Gaeumannomyces graminis var. tritici (which causes take-all of wheat), Rhizoctonia solani AG-8 (which causes rhizoctonia root rot of wheat), Pythium irregulare, P. aristosporum, and P. ultimum var. sporangiiferum (which cause pythium root rot of wheat) on the population dynamics of Pseudomonas fluorescens 2-79 and Q72a-80 (bicontrol strains active against take-all and pythium ...

rhizoctonia solani is the most serious problem on sugar beet beta vulgaris l. grown in north dakota and minnesota. picoxystrobin, a quinone outside inhibitor, and penthiopyrad, a succinate dehydrogenase inhibitor, were used alone and in combinations for controlling r. solani ag 2-2 iiib on sugar beet under greenhouse conditions of 22 ± 2 °c and a 12-h photoperiod. fungicides were applied in-fur...

several species of phytophthora cause crown and root rot diseases of herbaceous and woody plants. crown and root rot of pistachio trees cause significant damages in infected orchards. the effect of foliar application with elite (fosetyl-al) in 2 and 2.5 g/l was evaluated in greenhouse experiments. the frequency of mortality, fresh and dry weight of roots and shoots, height, intensity of crown r...

Sugar beet production is threatened by beetroot rot, which can be triggered consecutive monoculture. Previous studies have shown the beneficial function of microbes affiliated with different plant compartments in inhibiting various pathogens. However, whether sugar root recruit particular at risk rot still unclear. Therefore, this study explored composition and community structure bacteria fung...
