U.S. entomologists say a careful choice of nitrogen-fixing bacteria might provide soybean farmers protection against an invasion of soybean aphids. Pennsylvania State University researchers said soybeans are legumes -- plants that can have a symbiotic relationship with nitrogen-fixing bacteria called rhizobia and therefore do not need additional nitrogen fertilizer. Each type of legume -- peas, beans, lentils, alfalfa -- have their own rhizobia. Soybeans are from Asia and so there were...

A U.S. agriculture economist says the fight against the destructive soybean aphid is a success that will pay big dividends during the coming years. Michigan State University Professor Scott Swinton says state and federal governments have spent $17 million on soybean aphid research and education since 2003. Swinton said the net economic benefit of that integrated pest management work should reach $1.3 billion during the next 15 years. This is an example of what a good payoff you can get as a...

U.S. biologists have discovered high atmospheric carbon dioxide levels negatively affect a soybean plant's defenses against leaf-eating insects. Professor Evan DeLucia and colleagues at the University of Illinois said deforestation and the burning of fossil fuels have significantly increased carbon dioxide levels since the late 18th century. Currently, CO2 in the atmosphere is about 380 parts per million, DeLucia, an author of the study, said, and it's predicted to reach 550 parts per million...

Over the past decade, two-thirds of Indiana growers have shifted to planting their soybean crop earlier because they believe that earlier planting increases yield. Planting date is probably one of the most important yet least expensive management decisions that significantly affects soybean yield. Few scientists, however, have studied the effect of early-planting dates on soybean yield components and the impact of early planting on seed composition.To answer this question, Andrew P. Robinson...

By Mikkel Pates, Agweek Magazine Aug. 5--Planting in the region is going gangbusters. In most of the eastern half of North Dakota, small grains harvest is well under way, according to the most recent government reports. Small grains conditions declined for the fourth straight week, according to the National Agricultural Statistics Service; however, small grains development in the "milk stage" was ahead of the average pace. Spring wheat was 59 percent turning ripe, compared with...

By Daryll Ray, Farm Talk Newspaper, Parsons, Kan. Jul. 16--One of our readers raised a question about a statement we included in a recent column on China's impact on world agricultural commodity prices. In the column titled "USDA top officials versus USDA data" we wrote, "In the current environment, China's increase in demand for oilseed complex needs to be put in context. Rather than placing a significant upward pressure on world crop prices over the last decade, it could be argued that...

Carrying the right bacterial hitchhiker can make the difference between life and death for an aphid. Pea aphids are often under attack by wasps seeking to lay their eggs inside aphids, turning them into an all-you-can-eat buffet for the larval wasps. The aphids vary in their resistance to the wasps, which scientists had chalked up to genetic differences between aphids. But it's not in their genes at all -- the wasp-resistant aphids owe their lives to the symbiotic bacteria carried inside...

TOLEDO, Ohio (AP) -- Farmers are bracing for what researchers predict will be the return of an insect that attacks soybeans in the Midwest, where most of the crop is grown. For now, farmers must decide whether it makes sense to spray for soybean aphids before the insects emerge. Some say they will wait until they know whether their fields have been infested. Others aren't taking chances. "All of the research points to this being the year for aphids," said Allen Armstrong, who plans on...
