How is boron deficiency related to citrus greening?

If you ever looked at a citrus tree or a grove and wondered, how do the citrus psyllids find the trees? The answer might be methyl salicylate. So this study was looking at boron deficiency in citrus, and it found that boron deficient trees were emitting more methyl salicylate, which is a voc, a volatile organic compound. And this elevated level of methyl salicylate then attracted more Asian citrus psyllids to the trees. Just read you a quick section from this paper. Our study demonstrated that boron deficiency facilitated the feeding behavior of psyllid adults through elevated release of methyl salicylate coupled with weakened mechanical properties of cell wall. If you want to learn more about the connection between plant nutrition and insect attraction to crop plants, I hope you'll follow along because we're going to keep looking at more research and more review articles exploring this topic.
