P
lant Pests & Diseases and Their Management
Butterflies are not the only creatures that are fond of host and nectar plants. From yellow milkweed aphids to deer,
mealy bugs to ants, host plants are often under attack.
Not only do they eat and/or weaken plants, they also spread plant disease from plant to plant.
Rhizoctonia to damping off, plants are susceptible to diseases. These diseases may be spread by seed, rain, plant pests, or other means.
Due to the spread of a virus in milkweed by thrips, one farm had to destroy thousands of milkweed plants and start a totally new crop of milkweed.
If the farmer had taken control of the thrips when they first appeared and destroyed the first plants showing signs of this plant virus,
most of those milkweed plants would have been saved.
Your government agricultural agency will accept samples of pests and/or diseased plants for identification and will offer suggestions for control methods.
These submissions may be carried by hand or shipped to the office. Visit or phone your County Agent to locate the proper office to contact for plant pest/disease identification.
When submitting a sample for identification, include a letter stating that your "plants are used for butterflies
and please keep that in mind with suggestions for control".
