water into the cold air. Knight explains the process. "The water hits the ground as sleet, or ice pellets, not 'snow' to an atmospheric scientist. Anyone standing under the spray from a snow machine wouldn't call it snow either." Without special prov...

insecticides in refuges should not severely compromise the value of refuges. This makes the high dose/refuge strategy more practical by allowing farmers to protect their crops in refuges. The new theory could lead to new resistance management strate...
