Will global warming improve crop production?

Winter temperatures are on the rise and scientists note this change will actually increase a plant’s exposure to freezing temperatures

Scientists from Agriculture and Agri-Food Canada predict crops will be at a greater risk of winter damage in the future even though the climate will be warmer. Perennial forage crops are grown on more than 40% of the cultivated land in Eastern Canada and other regions of North America, where they constitute the backbone of the livestock industry. The

“Black clocks” call time on invasive flatworm

Entomologists in Belfast may finally have found a way of limiting the spread of the New Zealand flatworm, which invaded the British Isles in the 1960s. Speaking at the Royal Entomological Society’s national meeting Entomology 2002, which will take place at Cardiff University on 12–13 September 2002, Dr Archie Murchie of the Department of Agriculture and Rural Development (Northern Ireland) will announce that certain British beetles could help repel the invader by preying on it. Finding a natural pred

Rainforest researchers hit pay dirt

It shouldn’t be there, but it is. Deep in the central Amazonian rainforest lies a rich, black soil known locally as terra preta do Indio (Indian dark earth) that farmers have worked for years with minimal fertilization. A Brazilian-American archeological team believed terra preta, which may cover 10 percent of Amazonia, was the product of intense habitation by Amerindian populations who flourished in the area for two millennia, but they recently unearthed evidence that societies lived and farmed

Why plants’ soapy defences against disease don’t always wash

Natural soaps are an important weapon in the armoury that plants deploy to protect against disease attack, but a report today, in the international journal Nature, describes how disease-causing microbes can turn these plant defences to their own advantage. Scientists at the Sainsbury Laboratory (SL)[1] Norwich, UK, have discovered that fungi that attack tomatoes break down the natural soaps that help protect the plant against infection. Even worse for the plant, these breakdown products then interfe

Report focuses on the science and safety of genetically modified crops

Events like the September 2000 discovery of biologically engineered corn in fast food tortillas have focused media attention and stirred controversy about genetically modified organisms. While new approaches in agricultural biotechnology have improved crop quality and yield, the incorporation of genes from other organisms into food plants has raised concerns about possible health risks and environmental consequences. A new report from the American Academy of Microbiology (AAM) looks at the case of a

Cornell researchers turn conventional thinking about canned corn on its ear

Canned corn may be healthier for you than corn on the cob, according to a study by Cornell University scientists. The researchers say that heat processing of sweet corn significantly raises the level of naturally occurring compounds that help fight disease.
The findings are reported in the August 14 issue of the Journal of Agricultural and Food Chemistry, a peer-reviewed publication of the American Chemical Society, the world’s largest scientific society.

Sweet corn is the number-
