Powdery Mildew Caused by an Oidium sp. on Twenty-One Annual Medicago spp. in California

Bacillus sp. BS061 Suppresses Powdery Mildew and Gray Mold

The use of a microorganism, or its secretions, to prevent plant disease offers an attractive alternative or supplement to synthetic fungicides for the management of plant disease without the negative effects of chemical control mechanisms. During a screening for microorganisms with the potential to be used as microbial fungicides, Bacillus sp. BS061 was isolated from a plant leaf. The strain BS...

In vitro screening of fungicides and tannins against fungal pathogens of jujube fruits

Introduction Jujube (Ziziphus mauritiana Lam.) tree is subjected to attack by different fungal pathogens causing various diseases. In India, powdery mildew (Oidium sp.) causes defoliation and fruit-drop. Sooty mold (Cladosporium zizyphi) causes leaves to fall. Leaf spot results from infection by Cercospora spp. and Isariopsis indica var. zizyphi. Leaf rust, caused by Phakopsora zizyphi-vulgaris...

Genetic dissection of resistance to anthracnose and powdery mildew in Medicago truncatula.

Medicago truncatula was used to characterize resistance to anthracnose and powdery mildew caused by Colletotrichum trifolii and Erysiphe pisi, respectively. Two isolates of E. pisi (Ep-p from pea and Ep-a from alfalfa) and two races of C. trifolii (races 1 and 2) were used in this study. The A17 genotype was resistant and displayed a hypersensitive response after inoculation with either pathoge...
