Smelling Huanglongbing for Early-Detection

Josh McGillCitrus Greening

Another early-detection method being developed works by smelling huanglongbing infections in trees. This method detects the different scents plants give off. Researchers at the University of California, Davis have created a test that could lead to advances in fighting huanglongbing (HLB) disease in citrus. Researcher and professor of mechanical and aerospace engineering, Christina Davis, said the test looks for a …

Monitoring Plant Metabolism to Detect HLB

Kayla MercerCitrus, Citrus Greening

HLB pre-screening through analyzing plant metabolism holds potential to be a relatively inexpensive option for growers. Caroline Slupsky, professor in the Department of Nutrition and Food Science and the Department of Technology at the University of California, Davis, is looking at the metabolism of citrus trees and analyzing changes as indicators of stress and disease. Plants’ metabolic pathways change in …

ACP Movement Shows History Repeating Itself

Kelsey FryCitrus, Legislative

Research is looking at what we can learn from the Asian citrus psyllid’s (ACP) history, specifically ACP movement throughout Southern California. Psyllid finds in Central California are mimicking the insect’s history of spread. University of California, Department of Agriculture and Natural Resources held it’s California Asian Citrus Psyllid and Huanglongbing Research and Extension Summit at UC Riverside. The summit was …

HLB and ‘Tolerance’ as a Practical Matter in Choosing Rootstocks

Tacy CalliesRootstocks

By Bill Castle (Editor’s note: Click on the graphs throughout the article to enlarge them.) By classic biological definition, a particular citrus rootstock-scion combination when infected with Candidatus Liberibacter asiaticus (CLas) would be considered tolerant if infected trees had no more than slight reductions in performance, sometimes accompanied by a reduced level of the pathogen. That definition implies that the …

UF/IFAS Scientists Zeroing in on Better Mandarins

Daniel CooperCitrus

In their quest to develop higher quality mandarins, University of Florida/Institute of Food and Agricultural Sciences (UF/IFAS) researchers are zeroing in on the traits that will help them breed the best fruit. Last year, they released the mandarin cultivar currently known as ‘7-6-27,’ which UF/IFAS researchers say is soaring with interest, and with more than 100,000 trees already ordered. Sponsored …

Discussing Genetic Engineering With a Concerned Public

Josh McGillCitrus

By: Kevin Folta Our farm producers have brought unprecedented low-priced, safe food to the United States and the world. Despite the success, there are challenges to sustained production that may best be solved with genetic engineering. These technologies have proven safe and effective for almost two decades, mostly in the arena of high-acreage agronomic crops like corn, soy and cotton. …
