Combining IPCs and Brassinosteroids to Protect Young Citrus Trees

Josh McGillIPCs, Research

Research studies show that about 60% of Florida citrus trees are infected by HLB disease within six months of planting. By one year, 100% of citrus trees are infected. For that reason, the use of individual protective covers (IPCs) has become very popular to protect young citrus trees from the Asian citrus psyllid (ACP). The covers have proven to be …

Products Proven to Help With HLB

Josh McGillHLB Management, Research

Researchers offered updates on products proven to help against the devastating citrus disease HLB in a virtual seminar on April 27. University of Florida Institute of Food and Agricultural Sciences horticulturists Tripti Vashisth and Fernando Alferez discussed the benefits of gibberellic acid (GA) and brassinosteroids, respectively. Vashisth reported that GA-treated Valencia orange trees dropped less fruit and increased fruit yields …


Webinar to Address PGRs and Fruit Drop

Josh McGillFruit Drop

Florida citrus growers can learn more about the use of plant growth regulators (PGRs) in the fight against fruit drop at an upcoming online seminar. The webinar will be at 10 a.m., April 27 and will be presented by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Speakers at the webinar, titled “Gibberellic Acid Research Update and …

Pests and Diseases in Trees With IPCs

Josh McGillHLB Management, Research

All indications are that the recent widespread use of individual protective covers (IPCs) on young citrus trees in Florida is beneficial, especially for excluding Asian citrus psyllids and the HLB they spread. If there is any downside, it may be that some other pests and diseases are more prevalent under IPCs. In a recent American Society for Horticultural Science webinar, …

Trial Confirms Benefits of IPCs

Josh McGillFlorida, HLB Management, Pests

Individual protective covers (IPCs) on citrus trees have become a more common sight in Florida groves in recent years. The bags that cover young trees exclude the Asian citrus psyllid (ACP) from feeding on the plants, thus protecting them from HLB. Some estimates suggest that more than 1 million IPCs are now deployed in the state’s citrus groves. During the …

CRDF Funds Fruit Drop Research, Hears Antibiotic Presentations

Josh McGillDiseases, Research

The Citrus Research and Development Foundation (CRDF) governing board on Jan. 25 approved a project aimed at reducing fruit drop by using potassium, zinc, gibberellic acid and the herbicide 2,4-D in different timing scenarios. The funding will allow University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher Fernando Alferez to finish two years of work that CRDF Chief …


Citrus Tree Covers Keep Deadly Psyllids Away

Daniel CooperCitrus Greening, HLB Management, Research

University of Florida (UF) scientists are finding that by covering new citrus trees with mesh, they can keep disease-carrying insects from harming the plants. That could be a big step toward stemming the deadly citrus greening disease, UF Institute of Food and Agricultural Sciences (IFAS) researchers say. Asian citrus psyllids can infect the citrus trees with greening, also known as …

Early Findings Show Plant Hormone May Help in HLB Fight

Daniel CooperCitrus Greening, Industry News Release, Research

University of Florida scientists think a group of hormones may eventually help growers battle citrus greening, but they still want to study them before recommending growers use the chemical. Fernando Alferez, an assistant professor of horticultural sciences at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), leads a team of UF/IFAS researchers studying the effects of Homobrassinolides …
