A tropical-fruit crop specialist at UF’s Tropical Research & Education Center in Homestead, Jonathan Crane has studied how hurricanes affect Florida agriculture. His research covers damage to fruit crops and to grove infrastructure such as irrigation systems due to high winds and flooding.

Rapid Structure-Based Annotation and Profiling of Dihydrochalcones in Star Fruit (Averrhoa carambola) Using UHPLC/Q-Orbitrap-MS and Molecular NetworkingJournal of Agricultural and Food Chemistry
Zhixin Wang, Jingwen Li, Alan Chambers, Jonathan Crane, Yu Wang
Dihydrochalcones are a subclass of flavonoids. There has been growing interest in dihydrochalcones for their health benefits and potential to modulate flavor, but their comprehensive profile in diverse plant species is lacking. Star fruit is a tropical fruit rich in dihydrochalcones. In this study, a systematic annotation using UHPLC/Q-Orbitrap-MS and molecular networking was established to rapidly identify dihydrochalcones in 12 star fruit cultivars.
Regulations and Guidelines for ChemigationEDIS

Chemigation is a process where an irrigation system is used for transport and delivery of agrochemicals, generally fertilizers and pesticides, to a crop (Haman and Zazueta, 2017). Drip or micro-sprinkler irrigation systems are often used in chemigation. If the irrigation is properly plumed and chemigation properly implemented, chemigation can help growers reduce chemical usage and costs as it is applied using existing irrigation distribution infrastructure.
Bacterial Black Spot (BBS) of Mango in Florida1EDIS
Jonathan Crane, Romina Gazis
South Florida has an estimated 1,351 acres of commercial mango production (Crane 2017). In addition, hundreds of thousands of mango trees are grown in home landscapes throughout central and south Florida (JH Crane, personal communication). Bacterial black spot (BBS), also known as bacterial canker, is caused by Xanthomonas axonopodis pv. mangiferaeindicae, most likely originating in India and spreading to other countries through the movement of contaminated plant material (Midha et al. 2012).
Sample Profitability and Cost Estimates of Producing Sweet Flavored Carambola (Averrhoa carambola) in south Florida.: FE1079, 4/2020EDIS
Fredy H Ballen, Edward Evans, Jonathan Crane, Aditya Singh
This 7-page fact sheet written by Fredy H. Ballen, Aditya Singh, Edward A. Evans, and Jonathan H. Crane and published by the UF/IFAS Food and Resource Economics Department reports the costs and returns of operating an established sweet-flavored carambola grove in south Florida. It is intended to provide a reference to help estimate the financial requirements of running an established grove.
ET-Based Irrigation Scheduling for Papaya (Carica papaya) in FloridaEDIS
Haimanote K Bayabil, Jonathan Crane, Kati W Migliaccio, Yuncong Li, Fredy Ballen
Three irrigation scheduling methods (set schedule, ET-based, and tensiometer-based) were tested for papaya production in south Florida. ET-based irrigation scheduling was found to conserve water effectively. This 6-page document primarily focuses on the ET-based irrigation scheduling techniques for papaya under Florida conditions.
