The agricultural use of atrazine, and other herbicides based on a chemical substance called triazine, often causes contamination both of underground water and overground water. For this reason food safety agencies have established control measures to prevent these pe...

More recycling on the farm could reduce environmental problems

...the University of Guelph, documents how semiclosed agricultural systems -- which he terms "regenerative" -- could enhance global sustainability of biological resources, curtail greenhouse gas emissions and groundwater contamination, and reduce farming's reliance on oil imports and water. A switch to regenerative...

For many insects, winter survival is in the genes

...d to the flesh fly. Each insect is a fairly common agricultural pest: the gypsy moth, the European corn borer, the walnut husk maggot, the apple maggot and the tobacco hornworm. Collectively, these species cause millions of dollars of damage annually. Hsp70 was active while all of the insects were in diapause....
