Answer to Question 1An important thing to learn about insects is that there will be fewer incidences of infestation if plants
are quarantined prior to their introduction to an existing collection. A plant quarantine means that a
plant is kept away from other plants, perhaps 30 feet or more, for a period of one to two weeks. Some
experts suggest a month of quarantine. By this time, an infestation, even if initially minor, would be
more readily seen. The most common way that an insect infestation enters a collection is through the
introduction of one infested plant.
Answer to Question 2Label information is of extreme importance. Pesticides are specific, meaning that they control
specified insects but do not affect others. In addition, they are only appropriate for crops and situations
listed such as ornamentals, tropical plants and greenhouses, fields and interiors. There is no such thing
as an all-purpose insecticide. Chemicals that may be used for outdoor gardens or greenhouses may not
be labeled for (and, therefore, not safe for) interiorscape use. Similarly, pesticides labeled for interior
plants are probably not suitable for home gardens. Never assume that a chemical may be used on
edible crops.
