The Laurentian Great Lakes have been successfully invaded by at least 182 nonindigenous species. Here we report on two new species, water hyacinth Eichhornia crassipes and water lettuce Pistia stratiotes, that were found at a number of locations in Lake St. Clair and Detroit River during autumn 2010. Both species are commonly sold in the water garden and aquarium trade in southern Ontario and e...

Garden-orchard systems (GOS) consist in intercropping various vegetables with fruit trees. They are very promising to produce fruits and sufficient quantity of adequate quality while limiting environmental impacts. We assessed the effects apple trees on spatiotemporal variations microclimatic conditions soil properties, their influence growth two (radish lettuce). performed measurements five ve...

Background on the Chemistry of Rotenone. Rotenone is a natural product isolated from certain subtropical and tropical members of the pea family found in South America and Southeast Asia. The use of rotenone by man may be ancient, as early explorers noted Peruvian natives using crude extracts of the Cubé plant to stun fish for eating.

Lettuce is consumed raw in salads and is susceptible to microbial contamination through environment, agricultural practices, and its morphology, thus, a potential vehicle for food-borne illness. This study investigated the effect of adoption of food safety and hygienic practices by lettuce farmers on the microbial safety of field sourced lettuce in Lagos State, Nigeria. Ten structured questionn...

Three garden vegetables—radish, carrot and lettuce—were cultivated in a pot experiment using two soils from the Příbram area polluted mainly by cadmium (Cd), zinc (Zn), lead (Pb) chromium (Cr). The of district, Czech Republic, are heavily as result atmospheric deposition toxic elements originating historic lead–silver mining smelting activities. results showed that lettuce absorbed highest amou...

The role of lytic bacteriophages in preventing cross contamination of produce has not been evaluated. A cocktail of three lytic phages specific for E. coli O157:H7 (EcoShield™) or a control (phosphate buffered saline, PBS) was applied to lettuce by either; (1) immersion of lettuce in 500 ml of EcoShield™ 8.3 log PFU/ml or 9.8 log PFU/ml for up to 2 min before inoculation with E. coli O157:H7; (...
