Updated version of “Insect Controls for the Greenhouse Industry” available at the MSUE Bookstore

This newly revised wall chart provides a summary of insecticides labeled to control greenhouse ornamental insect and mite pests.

Michigan State University Extension bulletin E-2696, “Insect Controls for the Greenhouse Industry,” is formatted as a poster-sized “wall chart” suitable to hang on a door or wall in or near the greenhouse. This chart is a list of all insecticides registered for use in Michigan that are labeled to control greenhouse insect pests including aphids, broad mites, fungus gnats, leafminers, mealybugs, scale insects, spider mites, thrips and whiteflies.

The wall chart consists of three separate charts with the main chart at the top containing the majority of the information. The insecticide brand or trade names are listed on the left by chemical class. They are numbered and in an alphabetical list on the bottom left of the poster in a separate chart with the numerical position of the chemical listed as an aid in locating it on the main chart. More detailed information about the chemical classes is listed in the chart on the lower right of the poster.

The main chart includes chemical classes, active ingredients, formulations, EPA registration numbers, REI, signal words and any safety or phytotoxicity considerations listed on the label. Brand names of products with the same formulations and active ingredients are also listed. There is also a column for tomatoes, peppers and herbs, as these are often grown as transplants for resale. (Consult MSU Extension bulletin E-0312, “2012 Insect, Disease and Nematode Control for Commercial Vegetables,” for insecticide recommendations for controlling vegetable insect pests. The Michigan Department of Agriculture and Rural Development will allow pesticides to be applied in greenhouses as long as the crop is listed on the label.)

This wall chart is a list of what is labeled and not a list of recommendations. Most of the labels listed on this chart have the disclaimer that the product should be applied to a few plants and checked for phytotoxicity several days later before spraying the whole crop. This is a recommended practice for all greenhouse products.

To obtain a copy of the publication, go to the MSU Extension Bookstore website and type in E2696 in the search bar, located in the upper left corner. The price for an individual copy is $7.
