For years I had with my Greengage 80-90% losses due to Pflaumensägewespe. Thus, only sporadically plums come into the stage of maturity. This year I have applied Calypso once immediately after flowering, and the result is fantastic. Just a couple of plums (which were pierced) are lost. Otherwise, to see a single entry or exit hole. So far, the tree like never before depends so full. I hope I can keep it at bay the plum fruit, then that is the best ever harvest at all. From me a clear recommendation. Although now no longer organic, but for the past few years are all organic attempts failed.
