Coffee rust, also called coffee leaf rust, devastating foliar disease of coffee plants caused by the fungus Hemileia vastatrix.
Leaf, or foliar, nematodes (Aphelenchoides species) and bulb and stem nematodes (Ditylenchus dipsaci) cause severe losses in vegetable and ornamental bulb crops, clovers, alfalfa, strawberry, sweet potato, orchids, chrysanthemums, begonias, and ferns.
In semi-arid and arid regions, accumulation of saline soils in a subsurface layer sometimes limits rooting of fruit trees, causes abnormal foliar symptoms, and reduces yields.
The plants are susceptible to alfalfa weevils and a number of foliar diseases, including common leaf rot and mosaic.
Later the stem resumes vegetative growth, and the megasporophylls then are interposed between whorls of foliar leaves and cataphylls; the usual arrangement is two to three whorls of leaves, then several whorls of cataphylls, followed by megasporophylls, but variations in this sequence are not unusual.
Epiphytic bromeliads (air plants such as Spanish moss, Tillandsia usneoides; Bromeliaceae) absorb water and minerals via foliar trichomes.
Fertilizer development was also important, from the discovery of superphosphate to the devising of modern kinds of foliar feeding.
Many plants that offer high-quality fruits schedule their foliar displays to coincide with the peak of bird migration.
This phenomenon of foliar color in grasses and wildflowers is largely overlooked, perhaps because it is so intimate.
This flora is preparing for winter the same way deciduous trees do, with a foliar display.
By now the forest floor is awash with the blossoms, like the foamy caps of foliar waves.
