In the South, most nursery managers have relied on methyl bromide for weed control in hardwood seedbeds. When methyl bromide is no longer available, handweeding times will likely increase unless management regimes adapt to the change. Some nursery managers will increase use of both sanitation practices and herbicides. Although several herbicides are registered for use on hardwoods, some can inj...

Rootstock cuttings infected with latent Grapevine Trunk Diseases (GTD’s) pathogens are a major problem for nurseries. These fungal include several species of the genera Phaeoacremonium, Phaeomoniella, Cadophora, Dactylonectria, Ilyonectria, Diaporthe and family Botryosphaeriaceae. Infected rootstock can cause losses up to 60 % during propagation post planting, be reservoir disease in vineyard. ...

Abstract The decrease in the productivity of sugarcane (Saccharum officinarum L.) can be pursued through intensification with treatment nursery. However, it is increasingly difficult to find a good growing medium for plants, such as mediterranean soil must managed. One efforts increase fertility by adding livestock manure which has potential organic fertilizer so that expected improve structure...

Accumulating evidence suggests that wheezing illnesses have at least part of their origin in the infantile period, wherein septal restructuring and alveolar formation ensue. Therefore, throughout infancy, genetic and environmental factors could affect bronchial development and future airway function. On this basis, we hypothesised that differential growth velocity, within the first 6 months of ...

Lygus lineolaris (Palisot de Beauvois), Lygus hesperus (Knight) and Lygus rugulipennis (Poppius) can cause multiple-leaders to form on conifer seedlings. Injury due to Lygus bugs has increased during the last two decades to the point where these bugs are now considered the worst insect pest at many conifer nurseries. At several nurseries, Lygus bugs have injured 30% or more of the seedlings. Su...
