Integrated Management of the Potato Leafhopper in Alfalfa
A fully developed integrated pest management (IPM) system uses all available strategies for a given pest or pest complex in a cropping system; incorporating host plant resistance, biological, cultural and physical controls and chemical control when necessary (Pedigo, 1999). Several such management strategies have been developed in alfalfa for the potato leafhopper (Empoasca fabae) (PLH). The fi...

متن کاملGlandular-haired alfalfa resistance to potato leafhopper (Homoptera: Cicadellidae) and hopperburn: development of resistance indices.
Eight proprietary genotypes of glandular-haired alfalfa, Medicago sativa L., supplied by two different companies, were compared for the degree and types of resistance to the potato leafhopper, Ernpoasca fabae (Harris), and hopperburn. A tube cage no-choice bioassay was developed to test leafhopper mortality, feeding, settling preferences, severity of hopperburn symptoms (in this case, defined a...
متن کاملAlfalfa Plants
Experiments were performed in a laboratory chamber to investigate the influence of alfalfa plants on the fate and transport of trichloroethylene (TCE) fed at 200 μl/l concentration in the entering ground water. Concentrations of TCE in the aqueous and gas phases were regularly monitored in the chamber. Evapotranspirational fluxes of TCE were also reported from the soil to the headspace of the c...
متن کاملNutsedge (cyperus Spp) Control in Alfalfa
The competitive advantage of purple and yellow nutsedge in low desert alfalfa production areas of Southern California and Arizona is due to a combination of factors. These include frequent harvest and irrigation, high incident solar radiation, high summer temperatures that are supraoptimal for alfalfa growth, and the presence of C4 photosynthesis and vegetative reproduction (e.g., tubers) in nu...
