A team of scientists, led by a group at the University of California, Riverside, has received a five-year, $5.1 million grant from the U.S. Department of Agriculture to fight a disease that is devastating the citrus industry.

The team, led by Caroline Roper, an associate professor of plant pathology, will design and identify bactericides, which are chemicals that kill bacteria, to target Huanglongbing, a bacterial plant disease decimating citrus trees worldwide. They also will focus on better understanding the pathways those bactericides travel inside citrus trees. Continue reading

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) is publishing a final rule to allow the importation of fresh lemon fruit from northwest Argentina into the continental United States.

Over the last 10 years, APHIS has thoroughly reviewed Argentina’s citrus production and packing practices and fully evaluated pest risks to U.S. agriculture. The review included a comprehensive pest risk assessment that was amended several times to account for new scientific information and address public comments. It also included site visits in 2007, 2015, and most recently in September 2016 to observe production areas, packing practices, and trace back abilities. As a result, APHIS has determined lemons produced in northwest Argentina can be safely imported into the continental United States utilizing a systems approach. Continue reading
