Pennsylvania is on a mission to stop the spotted lanternfly. It's been six years since the invasive insect first arrived in the state, and it's still a problem that is not under control.

Farm tour highlights the need for agricultural research

AG leaders say the farm economy is in the worst shape since the 80's; farmers face challenges, including but not limited to: low prices, weather, and now, COVID-19.

Impact of animal infectious disease to be focus of conference at Penn State

Animal infectious illnesses such as avian influenza and African swine fever pose a significant threat to animal health and welfare and can cause economic instability and food insecurity for people all over the world.

Research looks at effectiveness of biopesticide on invasive insect

Researchers are hoping to fight an invasive species in Pennsylvania with fungus native to the state. The spotted lanternfly poses a threat to the state's $18 billion grape, tree fruit, and timber industries.

Spread of African swine fever has lawmakers looking at ways to keep disease out of Pennsylvania

Three words kept coming up at a joint meeting of the House and Senate Agriculture and Rural Affairs Committees this week – African swine fever. The committees meet to discuss biosecurity and animal health with much of the meeting focused on the disease, which has killed as much as half the pigs in China and could have a devastating effect on not only Pennsylvania but the U.S.

Automation on display at Ag Progress Days

A shrinking labor pool has forced farmers both locally and nationally to seek other measures to ensure high yields on their crops while also maintaining human-level efficiency. Researchers at Penn State are looking at ways to mitigate the dwindling labor workforce, and they’ve collaborated with local farmers through automation to help compensate.
