Control of Brown Stripe Downy Mildew of Maize by Metalaxyl
LAL, S., S. C. SAXENA, and R. N. UPADHYAY. 1980. Control of brown stripe downy mildew of maize by metalaxyl. Plant Disease 64:874-876. Seed treatment with metalaxyl at 4 g/ kg controlled brown stripe downy mildew (Sclerophthora rayssiae var. zeae) of maize up to 30 days after planting. When combined with seed treatment, one foliar application of metalaxyl (225 ppm) on the 30th day after plantin...
متن کاملSugary disease or Asian ergot of sorghum - Claviceps sorghi
Claviceps sorghi is a pathogen of Sorghum bicolor found only in India and Southeast Asia. The more widespread C. africana is predominant even in India; C. sorghi appears to be marginalized in its restricted range. A significant difference in invasiveness is the relative production of inoculum that spreads plant-to-plant. Claviceps sorghi produces few to no secondary conidia from macroconidia on...
متن کاملCharacterization and genetic distance analysis of isolates of Peronosclerospora sorghi using AFLP fingerprinting.
Sorghum downy mildew, caused by the obligate oomycete Peronosclerospora sorghi, has been controlled through the use of resistant cultivars and seed treatment with metalaxyl. A recent outbreak in fields planted with treated seed revealed the presence of a metalaxyl-resistant variant. Here, PCR-based methods including amplification from RAPD primers and two systems of automated AFLP analysis have...
متن کاملPolygalacturonase-inhibitor proteins in pearl millet: possible involvement in resistance against downy mildew.
Polygalacturonase-inhibitor protein (PGIP) is a defense protein found in plant cell walls. It prevents the degradation of pectin by modulating the endo-polygalacturonase activity. The present study has used heterologous anti-bean PGIP probes to investigate the role of PGIP in pearl millet [Pennisetum glaucum (L) R. Br.] resistance against downy mildew caused by oomycete pathogen Sclerospora gra...
متن کاملDowny mildew resistance in Arabidopsis by mutation of HOMOSERINE KINASE.
Plant disease resistance is commonly triggered by early pathogen recognition and activation of immunity. An alternative form of resistance is mediated by recessive downy mildew resistant 1 (dmr1) alleles in Arabidopsis thaliana. Map-based cloning revealed that DMR1 encodes homoserine kinase (HSK). Six independent dmr1 mutants each carry a different amino acid substitution in the HSK protein. Am...
