Jim Shields asked, > >Can you give us the name of the active ingredient in Dexol granules? Disulfoton -- 0,0-Diethyl S[2-(ethylthio) ethyl] I buy it in 8 oz./227 gr jars. The brand name is "Dexol Tender Leaf" -- there is also a liquid spray that I think is just called "Tender Leaf" and is recommended for sensitive foliage. Now that I bother to read the warning in detail, it can be "fatal if swallowed, inhaled, or absorbed through the skin." I assume you would have to be exposed to a fairly large quantity to be harmed by breathing or touching it. I do not handle it bare-handed and, as mentioned earlier, stay out of the plant room after applying it. It is intended for use on houseplants, but I wouldn't apply it to anything in a room of the house proper. If I have to put it on one of my few real "house" plants, I take the plant outside for the day. The "fumes" dissipate in 2-3 hours. I doubt that it is as dangerous to handle as Marathon, which is commonly used in commercial operations as Jim mentions. Jane McGary NW Oregon
