U.S. cattle producers applied 2.16 million pounds of insecticides to beef and dairy cattle in 1999. Applications made to beef cattle accounted for 72 percent of the total while insecticide use on dairy cattle accounted for 28 percent.

Xylene was the top active ingredient in total quantity used at 459,700 pounds followed by tetrachlorvinphos at 287,300 pounds and piperonyl butoxide at 154,300 pounds. These three active ingredients accounted for 42 percent of the U.S. total.

Of the total chemical applications made to cattle in 1999, the method of application was 37 percent by spray, 28 percent by pour-on, 9 percent by rubbing device, 9 percent by dust and 7 percent by injectable shot. All other methods (dip, mineral block, pill, ear tags, and other) accounted for the remaining 10 percent of applications.

A total of 1.55 million pounds of insecticides was applied to beef cattle in 1999. The top active ingredients in total pounds used on beef cattle were xylene, at 452,400 pounds, tetrachlorvinphos at 219,300 pounds, malathion at 140,900 pounds and famphur at 129,200 pounds.

Of the total chemical applications made to beef cattle in 1999, the method of application was 39 percent by pour-on, 18 percent by spray, and 11 percent by injectable shot. All other methods (dip, dust, mineral block, rubbing device, pill, ear tags, and other) accounted for the remaining 32 percent of applications.

A total of 606,400 pounds of insecticides was applied to dairy cattle in 1999. Piperonyl butoxide was the predominant active ingredient in total quantity used on dairy cattle at 101,700 pounds. Dichlorvos had the second highest quantity used at 96,200 pounds followed by cyfluthrin with 92,200 pounds.

Of the total chemical applications made to dairy cattle in 1999, the method of application was 65 percent by spray, 13 percent by pour-on, and 10 percent by both rubbing device and dust. All other methods (dip, mineral block, injectable shots, pill, ear tags, and other) accounted for the remaining 2 percent of applications.

A total of 354,400 pounds of insecticides was applied to cattle facilities in 1999. Tetrachlorvinphos had the highest quantity used at 125,200 pounds. Dimethoate had the second highest quantity used at 98,700 pounds followed by diazinon with 39,300 pounds.

A total of 148,400 pounds of insecticides was used to treat beef cattle facilities in 1999. Diazinon was the predominant active ingredient in treating beef cattle facilities with 39,300 pounds used. Malathion had the second highest quantity used at 15,100 pounds followed by dichlorvos with 14,600 pounds.

A total of 206,000 pounds of insecticides was applied to milk cattle facilities in 1999. Dimethoate accounted for 48 percent of the total at 98,700 pounds. Piperonyl butoxide accounted for 29,500 pounds or 14 percent of the total.

The 1999 agricultural chemical usage numbers are published by regions. Montana is included with Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming. Our region applied 328,000 pounds of insecticides to beef and dairy cattle in 1999. Applications made to beef cattle accounted for 99 percent of the total. A total of 70,800 pounds of insecticides was applied to cattle facilities in our region in 1999. Ninety five percent of these applications were to beef cattle facilities.

A complete listing of insecticides and amounts used by region is contained in the national agricultural chemical usage release and can be viewed at http:www/nass.usda.gov/.
