Along with cops, thieves, animals, and insects, "the fungus" is another obstacle in the path of a successful growing season. When the buds are roughly half developed they become susceptible to a fungus or bud rot. It appears that growing conditions for the fungus are best when temperatures are between 60 and 80 degrees and the humidity is high. The fungus is very destructive and spreads quickly. It is a spore type of fungus that travels to other buds via the wind so it is impossible to prevent or stop if weather conditions permit it to grow. If things should go badly and the fungus starts to attack your plants, you must remove it immediately or it will spread to other areas of the plant or plants. Some growers will remove just the section of the bud that is infected whereas other growers will remove the entire branch. Removal of the entire branch better insures that the fungus is totally removed, and also enables the grower to sample the crop a few weeks ahead of time. The main point in removing the fungus is to be very careful. Since it is a spore type of fungus, the accidental jerking of an infected bud will release some of the spores and they could fall onto a lower bud so by the next visit, you might have to pull that bud too. Also be careful in touching the fungus with your fingers because your fingers could pick up the spores and then when you touch the next bud, the spores could cling to it and start eating away at that bud.
