In the blueberry production regions of Florida, Georgia, and Mississippi, blueberry gall midge is a serious insect pest that affects rabbiteye and southern highbush blueberries, causing substantial yield loss by damaging fl ower buds. The midge is present from the south- eastern to the northern United States, where it feeds on vegetative buds of blueberry and cranberry (Vaccinium macrocarpon Aiton). The gall midge Dasineura oxycoccana (Johnson) (Diptera: Cecidomyiidae) was identifi ed as a pest in rabbiteye blueberries (Vaccinium ashei Reade) in the southeastern United States in the...

EM 8610 • August 1995 75¢ Cranberry Tissue Testing for producing beds in North America J. Davenport, C. DeMoranville, J. Hart, K. Patten, L. Peterson, T. Planer, A. Poole, T. Roper, and J. Smith Why use tissue testing? Cranberry plants require proper amounts of certain chemical elements from air, water, and soil to ensure adequate vegetative growth and fruit production. When levels of these nutrients in the plant are low, growth and yield may be affected. Severely reduced nutrient supply can lead to visible nutrient defi- ciency symptoms. Routine collec- tion and analysis of tissue samples...

Bransford, Lady Bird Johnson Wildflower Center. Alternate Names None known. Uses Information on the use of annual agoseris is limited. It is used by sage grouse (Pyle, 1992) and a native bee (Andrena cressonii cressonii) has been documented as visiting annual agoseris (Stubbs and others, 1992). Perennial species of Agoseris (also referred to as mountain dandelion) are known to be slightly or...

Erechtites hieraciifolius is a fast-growing, annual herb that is native to North, Central and South America and the Caribbean. It is recorded as an environmental and agricultural weed in areas both within and outside its native distribution. Mature plants can produce large amounts of wind-dispersed seed, facilitating the colonisation of new areas. It is adapted to grow in a wide range of disturbed anthropogenic habitats and can outcompete other species to form dense populations. It may also spread as a seed contaminant of crops. Currently, it is listed as invasive in Hong Kong, Hawaii, the Galapagos Islands, French Polynesia, Palau, US Minor Outlying Islands, New Zealand and Hungary. It is also considered a potential weed in Australia, where it is under quarantine.
E. hieraciifolius has been listed as a weed of the following crops: oat (Avena sativa), barley (Hordeum vulgare), maize (Zea mays), strawberry (Fragaria ananassa), onion (Allium cepa), carrot (Daucus carota), cranberry (Vaccinium macrocarpon), blueberry (Vaccinium spp.) and sugarcane (Saccharum officinarum);it is also a weed of fodder crops (e.g. Medicago sativa) and of mixed pastures (Darbyshire et al., 2012).
