Over fertilization can result in lush plant growth that is more susceptible to aphids and other sucking insects. Proper spacing of plants will promote healthy growth and discourage the development of foliar diseases such as Botrytis blight. Disease suppressive mixes and biological fungicides for use against certain soil borne diseases have recently become available. Initial Information Gathering information on the biology and life history of key pests is critical to insure effective decision making. Some selected references are listed at the end of this fact sheet.

Developing a Monitoring Program By thorough, consistent scouting, you can detect potential problems early and gather current information on the identity, location and causes of pest problems. In Connecticut, the Greenhouse IPM Program focuses on intensive hands-on educational training throughout the season. Employees can be trained to scout or growers can do their own scouting. However, scouting must be considered a high priority to ensure inspections on a weekly or as needed basis. Adequate time and personnel need to be assigned this important activity to insure that other, more routine greenhouse tasks do not interfere with scouting.
