Stem diseases of soybean with symptoms typical infection by Diaporthe spp. are common in the Northern USA. Information is limited, however, on characteristics associated pathogens. This study determined identity and symptomatic asymptomatic stems across diverse environments Minnesota. Plants stem canker, pod blight, plant dieback, as well plants, were sampled. Agar-based media PCR assays used t...

Loblolly pine (Pinus taeda L.) exhibits genetic resistance to fusiforrn rust disease (incited by the biotrophic fungus, Cronartiurn quercuum f. sp. fusifom) and pitch canker disease (incited by the necrotrophic fungus, Fusarium circinatum). In this study, a total of 14,015 loblolly pine cuttings from 1,065 clones were screened in controlled greenhouse conditions to identify phenotypes of clones...

Various biological amendments, including commercial biocontrol agents, microbial inoculants, mycorrhizae, and an aerobic compost tea (ACT), were evaluated, alone and in conjunction with different crop rotations, for their efficacy in introducing beneficial microorganisms, affecting soil microbial community characteristics (SMCC), and reducing soilborne diseases of potato in greenhouse and field...

Winter oilseed rape (Brassica napus L.) is the main source of domestic oil in central and northern Europe, bringing profits to farmers, but plants are often damaged by stem canker, caused two fungal species belonging genus Leptosphaeria. Due environmental concerns, benefits fungicide applications must outweigh disadvantages. The aim this work was determine effect canker on seed yield its qualit...
