Signal Word Chart


Signal Word (Precautionary Language) for Tree Fruit Pesticides

The signal word provides the applicator with important information about the toxicity, irritation and sensitization hazards associated with use of that pesticide. Word category is determined by the results of six acute toxicity studies submitted by the pesticide registrant (ingestion, inhalation, dermal absorption, eye effect and skin irritation tests). Danger/Poison products are the most toxic, followed by products marked Danger, followed by products marked Warning, whereas Caution products are the least toxic (Source 40 CFR 156).

In general, "Danger/Poison" and "Danger" chemicals require a 48 hr REI (72 hours for organophosphates used in areas with less than 25 inches of annual precipitation)." Warning" chemicals, in general, require a 24 hr REI and "Caution" chemical usually require a 12 hr REI. Note: Product specific reentry requirements are set by the chemical's registrant. Read all labels carefully to determine the right reentry period for the product you are using.
