Symptoms often appear first on older leaves. If weather conditions are moist and temperatures are low, masses of gray to violet fungal spores envelop infected leaves, which become girdled, collapse, and die. The dead leaf tissue is rapidly colonized by purple blotch, which is dark in color and obscures downy mildew. Downy mildew seldom kills onion plants, but bulb growth may be reduced. Bulb tissue, especially the neck, may become spongy and the bulb may lack keeping quality.
The small size of the glochids does not cause much pain, but is rather highly irritating. As such, these have been collected for use in the making of itching powder. Opuntia flowers are typically yellow, sometimes pink, and rarely white or anywhere inbetween these colors.Flowers are cup-shaped and do not have floral tubes, but instead the pericarples resemble round, extensions of the cladodes.It is impossible to determine if new growth is going to be a flower or a new cladode as they are identical when first appearing-often covered with cone-shaped deciduous leaves.any people despise the Opuntia, even those who otherwise love growing cacti. In recent times, however, there seems to be a renewed interest in the genus-particularly the species native to the Southwest U.S. and it is gaining in popularity.
