Can the leaf age influence the susceptibility to bacterial-leaf-spot and bacterial-halo-blight on coffee seedlings?

Bacterial Leaf Spot of Alfalfa '

The bacterial leaf spot described here was first recognized on Turkestan and Grimm alfalfa (Medicago sativa L.) in two locations at Madison, Wis., in August 1930. The alfalfa in both instances was in cultivated experimental rows and had been repeatedly splashed bywatering with a garden hose. In October 1931 the disease recurred under similar circumstances at one of these locations, but with the...

Effect of olive leaf powder on the performance and ileal bacterial count of broilers

This experiment was conducted to investigate the effects of olive leaf (OL) on the performance, abdominal fat pad and some ileal bacterial population of Cobb broiler chickens. A total number of 400 day-old chicks were randomly distributed into floor pens and reared under the same condition until 14 days of age. On day 14, each pen was randomly assigned to one of the five experimental treatments...

Season, Irrigation, Leaf Age, and Escherichia coli Inoculation Influence the Bacterial Diversity in the Lettuce Phyllosphere

The developmental and temporal succession patterns and disturbance responses of phyllosphere bacterial communities are largely unknown. These factors might influence the capacity of human pathogens to persist in association with those communities on agriculturally-relevant plants. In this study, the phyllosphere microbiota was identified for Romaine lettuce plants grown in the Salinas Valley, C...

Pecan Bacterial Leaf Scorch : Cultivar Susceptibility and Pathogen Transmission

Pecan bacterial leaf scorch (PBLS) and the pathogen Xylella fastidiosa were identified in 20 pecan cultivars observed in Louisiana commercial orchards over a twoyear period. The disease occurred in the majority of orchards observed and was distributed throughout the pecan growing areas of the state. Leaf scorch was most prevalent in the Cape Fear cultivar. A few other cultivars sometimes exhibi...
