|Section2= |Section8= }} Chlorothalonil (2,4,5,6-tetrachloroisophthalonitrile) is an organic compound mainly used as a broad spectrum, nonsystemic fungicide, with other uses as a wood protectant, pesticide, acaricide, and to control mold, mildew, bacteria, algae.〔 Chlorothalonil-containing products are sold under the names Bravo, Echo, and Daconil. It was first registered for use in the US in 1966. In 1997, the most recent year for which data are available, it was the third most used fungicide in the US, behind only sulfur and copper, with some 12 million pounds used in agriculture alone that year.〔(PESTICIDE USE IN U.S. CROP PRODUCTION: 1997 ) National Center for Food and Agricultural Policy, 1997.〕 Including nonagricultural uses, the EPA estimates, on average, almost 15 million pounds were used annually from 1990-1996.〔(Reregistration Eligibility Decision for chlorothalonil ), US EPA, 1999.〕 ==Uses== In the US, chlorothalonil is used predominantly on peanuts (about 34% of usage), potatoes (about 12%), and tomatoes (about 7%), though the EPA recognizes its use on many other crops.〔 It is also used on golf courses and lawns (about 10%) and as a preservative additive in some paints (about 13%), resins, emulsions, and coatings.〔 Chlorothalonil is commercially available in many different formulations and delivery methods. It is applied as a dust, dry or water-soluble grains, a wettable powder, a liquid spray, a fog, and a dip. It may be applied by hand, by ground sprayer, or by aircraft.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chlorothalonil」の詳細全文を読む スポンサード リンク
