Maria Luz said: "The arborist said if we only trim, we could keep them around awhile longer," External link

Mike Roberts says: “It’s a lesson in never being comfortable with where you are, and you’ve always got to be on the lookout for potential threats,” External link

Mike Roberts explains: “Some employees and customers headed to Brazil immediately to learn as much as they could. But from where we started with this, no one understood the potential,” “There’s a latency period from infection to symptoms, so it was much further down the road than we suspected at first. It had probably been here longer than we thought and spread further than we knew” External link

Jim Graham says: “We are working with a population of trees that is nearly 100% damaged or infected by the pathogen,” External link

Mike Roberts says: “Every bit of our citrus selling is related to HLB,” “Effectively every acre is infected, so all decisions–fertility, pest control–all of it has to do with managing HLB” External link

Mike Roberts says: “It’s all about getting as much life out of the tree as we can,” “For young trees, we used to make applications every six weeks, and now we may be in the grove applying insecticides for psyllids every three weeks–just trying to keep the tree healthy and get it to the fruit-bearing age. If the tree gets stunted early, it’ll never support a crop” External link

Jim Graham says: “Over a period of three seasons, we were able to see a reduction in the impact of high bicarbonates in the irrigation water on HLB-damaged root systems with acidification treatments that dropped soil pH from 6.5 to 6.0. Importantly, this soil pH adjustment increased uptake of calcium, magnesium, zinc, manganese and iron,” External link

Jim Graham says: “There have been some novel approaches to fighting greening,” “For example, there are recent studies of the benefits of different types of artificial and green mulches installed around newly planted trees. There have been multiple antibacterial therapies applied as sprays and soil drenches, including thermal heating of the tree’s canopy. Reduction of water and nutrient stresses has produced positive recovery of declining trees” External link

Mike Roberts explains: “We take one step forward and two steps back. Greening is a worthy opponent,” “We’re trying multiple fertilizer applications, including multiple dry applications, injections and foliar feedings. The idea is a constant feed of plant nutrients so the tree wants for nothing. And we work to stay focused on sound agronomy” External link

Mike Roberts says: “The changes we make today may not manifest themselves for a whole year,” “We’re trying to support the tree but not break the bank. We’re keeping these trees alive but losing the production game” External link

Jim Graham says: “We have a way to go, but they have found root stocks more tolerant and resilient to greening. However, it will take time to propagate, grow and plant replacement trees,” External link

Jim Graham says: “The holy grail will be at some point to block the vectors’ transmission of the bacterium into the tree,” External link
