We are getting a lot of rain this time of year in our Florida citrus groves. The good thing is that it’s helping the trees combat some diseases, such as greening. Most trees, including many sick ones, respond well to the abundant rain and ground and foliar fertilizers that are being applied to the trees. This reinforces my belief that abundant water is more important to helping citrus trees survive greening than initially thought. Others are coming around to this point of view, as shown by some new research that has been initiated to look into those questions. However, the abundant rain makes other diseases, such as citrus canker, worse in some cases. As you can see in this photo, we have a very large citrus canker lesion in an early-variety orange block. This lesion is over 2 inches high and 1 inch wide. Clearly, we have to be diligent about controlling diseases that reach these levels, because otherwise the crop is difficult to sell.
