Beneficial insects could be a citrus grower’s best friend. In a time when producers are applying insecticides to control the Asian citrus psyllid, the vector of citrus greening disease, it’s important to preserve the psyllids’ natural enemies, like lady beetles and lacewings. Jawwad Qureshi, University of Florida entomologist, implores growers to scout their groves periodically to see what insects are …
New research affirms a unique stable antimicrobial peptide (SAMP) found in an Australian plant can destroy HLB and help prevent infection.

Florida growers are being asked to take a survey on the use of cover crops and reflective mulch in citrus production. These systems are being investigated as potential means to improve soil health and reduce pest pressure from Asian citrus psyllids, which transmit the destructive citrus disease HLB. The survey is being conducted by researchers with the University of Florida Institute …
As temperatures increase across Florida, so does the risk for huanglongbing (HLB) disease, known as citrus greening. While the southern and central portions of the state remain vulnerable to HLB and Asian citrus psyllids (ACP) that spread the disease, growers in North Florida and South Georgia have so far been spared. But Xavier Martini, University of Florida entomologist at the …
“We’ve come a long way in the time that we’ve had HLB here in Florida,” says Michael Rogers. The director of the University of Florida Institute of Food and Agricultural Sciences’ (UF/IFAS) Citrus Research and Education Center says early HLB research “covered a wide range of topics.” Now, however, “We’re really narrowing down things that are of use to growers …
Two Florida citrus grower associations expressed disappointment over the recent Florida Department of Agriculture and Consumer Services’ (FDACS) decision to deny the use of the pesticide aldicarb in Florida citrus. “We are frustrated in the decision as we believe aldicarb will provide a powerful tool in the fight against citrus greening and can be used safely,” said Florida Citrus Mutual …
