These citrus and myrtle plants …
There has been much focus on the benefits of applications of plant growth regulators like gibberellic acid and 2,4-D, and more recently oxytetracycline hydrochloride to improve the health of citrus trees infected with HLB. Silicon also has been highlighted for its potential benefits to citrus. Mohammad Adnan Shahid, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor, …
