Replacing insecticides with sex in pest control

Genetically engineered male moths prevent females from reproducing

Cornell University researchers are combining two biotechnologies to control diamondback moths with sex instead of insecticide. The pesky feeders on crucifer crops, including canola, mustards and vegetables, have developed resistance to many insecticides as well as Bt (Bacillus thuringiensis), a soil bacteria that has been genetically engineered into corn and cotton to help control such

Multi-toxin biotech crops not silver bullets

When pests developed resistance to Bt crops such as corn, potatoes and cotton, seed companies had an answer: two-toxin varieties. But new research suggests it may be the wrong one. Bioengineered crops with genes taken from bacterium Bacillus thuringiensis have been widely grown since 1996. The genes produce Bt toxins, reducing the need for pesticide


U.S. subsidy cap debate pits big versus small farmers

Reuters / U.S. farmers would be limited to $125,000 a year in crop subsidies in a significant tightening of farm support rules proposed by four senators from farm and ranch states. There is no effective limit on payments now. Large operators collect the lion’s share of subsidies because they are based on each bushel of

U.S. seen growing one of the smallest cotton crops in decades

Reuters / U.S. farmers will plant one of the smallest cotton crops in two decades in 2013 as the fibre loses a battle for acreage to the more buoyant grains market, according to a Thomson Reuters poll. Ahead of the Beltwide Cotton conference here this week, an informal survey of market participants showed that American


New top Republican on ag committee

washington / reuters Mississippi Senator Thad Cochran has claimed the role of Republican leader on the Senate Agriculture Committee, giving the U.S. cotton and rice growing region a more powerful voice in the debate over how to reform farm subsidies. Cochran displaced Pat Roberts from Kansas, one of the largest wheat-growing states. Roberts was an

Developing nations to lead in biotech crops

Farmers in developing nations will sow more biotech crops than those in the industrialized world for the first time this year. Globally, the area planted with biotech crops rose eight per cent last year to a record 160 million hectares, or 395 million acres, according to the International Service for the Acquisition of Agri-Biotech Applications.






Brazil Brings Farming Muscle To Corn And Cotton

After transforming global agriculture by quintupling their soybean production since 1980, Brazilian farmers are now on the brink of crop breakthroughs in cotton and corn, long dominated by growers in America. Helped by high futures prices and a sustained local agricultural boom, cotton and corn acreage is spreading fast, despite being twice as capital intensive
