None of the Paclobutrazol products will cause damping off of plants but the water it is mixed with applied in copious amounts under humid, cloudy, cold weather conditions can add to fungal problems. During the Winter months be sure your soil mixes are a well draining type, keep the soils from getting water logged and keep as much air movement as possible around the plants so the foliage and stems stay dry. You can also use drenches such as Truban to control or eradicate water molds such as pythium and phytophtora.
