By Arnold Schumann, Ariel Singerman and Yu Wang Grapefruit production in Florida has been drastically reduced by huanglongbing (HLB) disease, from 40.9 million boxes in 2003–04 to 4.5 million boxes in 2018–19, according to the U.S. Department of Agriculture. Grapefruit varieties are particularly vulnerable to HLB due to cumulative losses from stunted tree growth, low fruit yield, high-percentage fruit drop, …
By Ozgur Batuman and Amit Levy Management options for huanglongbing (HLB) are limited and rely heavily on insecticides for controlling Asian citrus psyllid (ACP) populations, even when integrated with other cultural control methods. Chemical strategies are expensive and, if not rotated, can contribute to the development of chemical resistance among ACP populations. In some cases, long-term chemical applications may have …
By Jawwad Qureshi Management of the Asian citrus psyllid (ACP) is needed in multiple environments, such as organic and conventional production systems and urban areas. However, the tools and approach may be different depending on the circumstances. Chemical control is the primary method used in commercial production to reduce psyllid populations, but the increased use of insecticides negatively affects the …
