Early freezes or severe cold can damage apple trees, a possible cause of later, rapid deaths. The decline is more common among densely planted trellised orchards (above right). MELISSA DOBERNIGG/THE BX PRESS CIDERY

Six years ago, an unpleasant surprise greeted plant pathologist Kari Peter as she inspected a research orchard in Pennsylvania. Young apple trees were dying—and rapidly. At first, she suspected a common pathogen, but chemical treatments didn't help. The next year, she began to hear reports of sudden deaths from across the United States and Canada. In North Carolina, up to 80% of orchards have shown suspicious symptoms. "Rows of trees collapse for what seems like no reason," says Peter, who works at the Pennsylvania State University Fruit Research and Extension Center in Biglerville.

Pests and diseases are taking a substantial bite out of the world’s five major food crops — in some cases, up to 40 percent — according to a recently released publication, one of the first to inventory the impact on a global scale.

When Tomas Lowenstein of Agricola La Reina, a mushroom farm in Miranda, Venezuela, needs spawn, or "seed," to grow his crops, his chosen point of contact isn't around the corner or even in the country. It's more than 2,200 miles away in a laboratory on Penn State's University Park campus.

Cucurbit vegetables grown in the U.S., namely watermelon, cucumber, squash, pumpkin and muskmelon, are worth $1.35 billion. Faculty at Penn State in collaboration with 16 other universities will utilize funding awarded by the 2018 USDA Specialty Crop Multi-State Program to monitor and forecast cucurbit downy mildew (CDM) over the next three years.

Biocontrol has long been touted as a safer alternative to synthetic pesticides for both, farmworker safety and the environment. However, inconsistent efficacy has hampered its wide adoption for disease management. To address this issue, faculty at Penn State are leading a project, funded by the USDA Specialty Crop Multi-State Program. Their focus is on generating critical knowledge and resources needed to develop and deploy reliable biocontrol strategies that can help protect tomato production from Fusarium wilt, an increasingly problematic soilborne disease.

Research and awareness around the Spotted Lanternfly (SLF) continues to increase as proposals are selected for funding to help fight this invasive species. These sap-feeding insects are a major threat to U.S. agriculture, timber industry, and many managed and natural ecosystems, feeding on over 70 species of plants.
