For greenhouse growers poinsettias can be a very challenging crop to grow. According to Michigan State University Extension, poinsettias are extremely susceptible to diseases such as Pythium root rot and scab (Sphaceloma poinsettiae), heat and humidity stress, plant growth regulator (PGR) overdose and phytotoxicity, and numerous nutrient deficiencies. Cultivation practices such as keeping a clean greenhouse, not allowing dramatic swings in temperature or humidity, and providing a fertigation program with micronutrients can help prevent some of these production issues.
Michigan State University has made a nice overview of the most common problems such as Pythium, Sphaceloma poinsettiae, leaf distortion caused by rapid changes in heat and humidity, Phytotoxicity of Cycocel and Molybdenum deficiency.
