Dairy farmers generate nutrients in the form of cattle manure. Neighboring raspberry and blueberry farmers import nutrients in the form of fertilizer to maximize production. To improve the nutrient loop, Washington State University assembled a team of scientists to study how berry growers can put dairies’ plentiful waste product to a use in their fields. “We want to connect those …

Historically credited as being the first bacterium ever characterized as a plant pathogen, fire blight is a bacterial disease that leads to significant losses of pear and apple. The role of insects in the spread of this disease has been long studied. In a new study, plant pathologists based at Cornell University and Cornell AgriTech take a hypothesis that has …

University of Florida Institute of Food & Agricultural Sciences – Florida citrus growers who face the most severe citrus disease in history notice how citrus trees under oak tree hammocks appear to tolerate the disease. Lukas Hallman believes oak trees may hold a compound that boosts the citrus trees’ ability to tolerate the disease. Hallman is a graduate student at …

Chew on this the next time you eat a blueberry: Every single blueberry is the result of a flower that was pollinated by a bee.  In other words: No buzz, no berry. With that in mind, it’s no wonder blueberry growers bring in hives of honey bees or bumble bees when their blueberry bushes are in flower. “We are big believers …

Blueberry growers across America today established a new coalition, the American Blueberry Growers Alliance, to seek relief from rising imports that are harming their businesses.

New grants totaling $6.3 million will help UC Riverside solve problems facing American avocado orchards, including a lethal fungal disease called Laurel Wilt. Laurel Wilt can destroy an entire avocado orchard in a couple of weeks once symptoms develop. It is already present in Florida. Without effective treatments, it will inevitably spread to California, which is the nation’s leading producer …

Pear producers are turning to science in order to take a bigger bite out of the fruit market. U.S. pear production is only about one-seventh that of apple production. Reasons for this shortfall include relatively limited areas with a favorable growing climate; the large size of pear trees; and susceptibility to storm damage, climate change, and disease – particularly fire …

The United States will remain the largest exporter of fresh apples, pears, and table grapes to the Canadian market in marketing year (MY) 2020/21. FAS/Ottawa forecasts a five percent growth in Canadian apple production for MY 2020/21 with fewer weather-related challenges. A reduction in the marketed production of Canadian pears and table grapes is anticipated as a result of weather …
