Rates of nitrogen application were studied in relation to commercial yield and fruit quality of cucumber plants (Cucumis sativus L. cv. Bunex). All plants were grown under controlled conditions in a greenhouse. Treatments consisted of the application of N as KNO3 (N1, 2.5 g m-2; N2, 5 g m-2; N3, 10 g m-2; N4, 20 g m-2; and N5, 40 g m-2). The fruits of cucumber from the N3 and N4 treatments were...

Efficacy against the sweetpotato whitefly (SPWF) Bemisia tabaci (Gennadius) of an insecticidal soap, two horticultural oils (one vegetable and the other petroleum based) and 15 detergents was evaluated under greenhouse conditions. Applications were directed to the underside of infested zucchini squash, tomato, or poinsettia leaves. Live nymphs were distinguished by their ability to deposit hone...

Reclaimed wastewater is an important source of irrigation in semiarid and arid zones. Here we report data on carbamazepine (CBZ) uptake by cucumber plants in hydroponic culture and greenhouse experiments using different soil types irrigated with fresh water or reclaimed wastewater. Data obtained from the hydroponic culture experiments suggest that CBZ is mainly translocated by water mass flow, ...

BACKGROUND Pythium ultimum is a plant pathogen that causes significant yield losses on many economically important crops. Chemical treatment has been used for disease control. In searching for alternatives, venom piperidine and piperideine alkaloids from red imported fire ants were tested against P. ultimum in vitro, and piperideines were employed to control cucumber damping-off in the greenhou...

The creation of a special environment for the enhancement of plant growth, outside the normal growing season, dates back to 500 B.C. The Gardens of Adonis, in ancient Greece, saw the first application of covering and protective materials to foster the growth and propagation of ornamental flowers. Another historical milestone occurred when Tiberius Caesar instructed his gardeners to provide a su...
