Combining IPCs and Brassinosteroids to Protect Young Citrus Trees

Josh McGill IPCs, 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 …

Use Physical Barriers for Root Health

Josh McGill IPCs, Root health, Tip of the Week

By Larry Duncan Citrus trees in Florida soils infested with diaprepes root weevil (Diaprepes abbreviatus) or sting nematode (Belonolaimus longicaudatus) frequently contend with devastating damage to their root systems. This is made even worse by root loss due to huanglongbing (HLB) disease. Where soil conditions are conducive to the insect or nematode, it is very difficult to prevent major economic …

Pests, Pathogens and IPCs

Josh McGill IPCs, Pests, Research

By Lauren Diepenbrock, Megan Dewdney, Fernando Alferez, Jawwad Qureshi and Ozgur Batuman Individual protective covers (IPCs) are becoming commonplace in citrus production to support the development of young trees after planting. IPCs are made of fine mesh and are intended to keep Asian citrus psyllids (ACP) off young plants. Because ACP can transmit the pathogen that causes citrus greening/huanglongbing, preventing …

IPCs Improve Fruit Yield and Quality

Josh McGill HLB Management, IPCs, Research

By Fernando Alferez, Ute Albrecht, Susmita Gaire, Ozgur Batuman, Jawwad Qureshi and Mongi Zekri University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers established a field trial in February 2018 to evaluate the efficacy of individual protective covers (IPCs) to prevent Asian citrus psyllids from spreading HLB and to study the effects on tree growth and physiology. The …

Pests and Diseases in Trees With IPCs

Josh McGill HLB 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 McGill Florida, 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 …
