Researchers to Study New HLB Treatment Method
University of California (UC) Davis research scientist Louise Ferguson is taking part in a $3.4 million project titled “Development of an automated delivery system for therapeutic materials to treat HLB-infected citrus.” The study is funded by the U.S. Department of Agriculture’s National Institute of Food and Agriculture. The four-year project includes work by researchers at the University of Florida, UC …
Taking Technology to the Grove
By Ernie Neff Jerry Mixon’s use of netting to keep birds from blueberries helped pique his interest in growing citrus under protective screen (CUPS) to exclude HLB-spreading psyllids. But he credits University of Florida researcher Arnold Schumann with helping him bring his Polk County CUPS project to fruition. Mixon met Schumann in 2015, the year after Schumann’s 1-acre CUPS was …
Vigilance Keeps HLB at Bay
By Len Wilcox California agriculture has long kept a watchful eye on the spread of HLB (huanglongbing or citrus greening disease).
