“…In contrast, hairy nightshade does not persist in dense shade, although it is able to compete for light in widely spaced row crops (Blackshaw 1991). These two closely related species also differ markedly in response to herbicides (Quakenbush and Andersen 1985;Ogg 1986) and in geographic distribution (Bassett and Munro 1985), with eastern black nightshade more common in eastern and hairy nightshade in western North America.…”

“…Yun and Taylor (1986) suggested that the thinner leaves produced by shade-tolerant plants may result in lower water use efficiency. Eastern black nightshade tends to have larger but fewer leaves than hairy nightshade, and the leaves of eastern black nightshade are glabrous, whereas those of hairy nightshade are pubescent with glandular hairs (Bassett and Munro 1985;Hermanutz and Weaver 1991). To design effective control strategies for these two nightshade species, more information is needed on their biology and ecology.…”

“…Eastern black nightshade (Solanum ptycanthum) and hairy nightshade (Solanum sarrachoides) are the two most common annual nightshade species found in Ontario (Bassett and Munro 1985). Both are weeds of row crops, particularly soybeans, dry beans, and tomatoes, and cause significant economic losses through reductions in crop yield, quality, and harvesting efficiency.…”

Tan, C. S. and Weaver, S. E. 1997. Water use patterns of eastern black nightshade (Solanum ptycanthum) and hairy nightshade (Solanum sarrachoides) in response to shading and water stress. Can. J. Plant Sci. 77: 261-265. Greenhouse and growth room experiments were conducted to determine the effects of shading and water stress on transpiration of eastern black nightshade (Solanum ptycanthum) and hairy nightshade (S. sarrachoides). Transpiration rates were estimated using heat balance stem flow gauges. Eastern black nightshade transpired significantly more water than hairy nightshade given ample water and light. Eastern black nightshade also transpired more water than hairy nightshade when shaded. Transpiration of both species increased with light intensity and was relatively insensitive to changes in soil volumetric water content above 0.10 m 3 m -3 , but declined sharply below that level. Eastern black nightshade had significantly more stomata than hairy nightshade, particularly on the lower leaf surface. Les taux de transpiration étaient estimés par une méthode de bilan calorifique au moyen de flux-mètres caulinaires. En bonne condition d'éclairement et d'alimentation en eau, la morelle noire de l'est transpirait significativement plus que la morelle poilue. Sa transpiration était également plus abondante en milieu ombragé. Chez les deux espèces, la transpiration augmentait avec l'intensité lumineuse. Par ailleurs elle était relativement insensible au changement de teneur volumétrique en eau du sol au-delà de 0,10 m 3 m -3 , mais en deçà de ce niveau, elle accusait une diminution brutale. La morelle noire de l'est porte significativement plus de stomates que la morelle poilue, spécialement à la surface inférieure des feuilles.

“…Both species can cause severe economic losses by reducing crop yield and quality, and by interfering with harvest operations (Bassett and Munro 1985;Weaver et al 1987). Several studies have documented differences between the two species in morphology and in response to herbicides (Quakenbush and Andersen 1985;Ogg 1986 These results parallel those of Roberts and Boddrell (1983), who found that hairy nightshade from eastern England germinated over a wide range of alternating temperatures in the absence of light, and of Weaver et al (1988), who showed that germination of eastern black nightshade from Ontario declined sharply in darkness and at mean temperatures below 20'C.…”

ABSTRACT. One week after emergence (WAE), linuron applied PRE caused 0.4% to 1.2% injury in "Etna", "Hooter", "SVM Tayler", and "Capri" cranberry bean and 3.1% to 3.6% injury in "Red Hawk", "Pink Panther", "Calmont", and "Majesty" kidney bean. At 2 and 4 WAE, there was no difference in injury among the dry bean cultivars. Contrast comparing injury due to linuron in cranberry vs kidney bean cultivars indicated 2.3%, 1.7%, and 1.2% greater injury in kidney bean compared to cranberry bean at 1, 2, and 4 WAE, respectively. Linuron PRE caused slightly greater injury in kidney bean compared to cranberry bean but crop injury was minimal with no adverse effect on plant height, shoot dry weight, seed moisture content, and yield under the environments evaluated. Based on this research, linuron applied PRE at the proposed rate of 1125 g·ai·ha −1 can be safely used in cranberry and kidney beans in Ontario.
