Supermarkets to Require Growers to Show Proof of Good Agriculture Practices (GAPs), Says PSU Study

March 20, 2012 |

News Release – UNIVERSITY PARK, Pa. – Pennsylvania supermarkets in coming years will continue to purchase fresh produce from local growers but increasingly will require them to show proof of employing good agricultural practices, or GAPS, according to a study by researchers in Penn State’s College of Agricultural Sciences.

Good agricultural practices are food-safety standards that reduce the risk of on-farm contamination of produce, according to Daniel Tobin, a doctoral candidate in agricultural and extension education, the study’s principal investigator. GAPs include recommendations for safe irrigation methods, use of raw and composted animal manure, worker health and hygiene, post-harvest handling practices, and traceability procedures. Read More

Integrated Weed Management Best Response to Herbicide Resistance, Says PSU Research Report

February 16, 2012 |

New Release – UNIVERSITY PARK, Pa. — Over-reliance on glyphosate-type herbicides for weed control on U.S. farms has created a dramatic increase in the number of genetically-resistant weeds, according to a team of agricultural researchers, who say the solution lies in an integrated weed management program.

“I’m deeply concerned when I see figures that herbicide use could double in the next decade,” said David Mortensen, professor of weed ecology at Penn State.

Since the mid-1990s, agricultural seed companies developed and marketed seeds that were genetically modified to resist herbicides such as Roundup — glyphosate — as a more flexible way to manage weeds, Mortensen said. About 95 percent of the current soybean crop is modified by inserting herbicide-resistant genes into the plants. Read More
