Apply a barn spray to the point of run-off to the ceilings and walls of all live- 

 stock buildings. Also spot-spray outside around windows and doors and along 

 fences in the lot. The following insecticides are suggested for this purpose: 



Insecticide 



Amount 

 per 100 

 gallons 

 of water 



Diazinon, 50-percent wettable powder 



Dimethoate, 23-percent (Cygon) liquid 

 concentrate 



Rabon, 25-percent liquid concentrate 



Ronnel , 24-percent (Korlan) liquid 

 concentrate 



16 pounds 



Length of 

 control 



2 to 4 weeks 



4 gallons 4 to 6 weeks 

 4 gallons 4 to 6 weeks 



4 gallons 1 to 5 weeks 



Use only ronnel in poultry houses. All materials are cleared for use in dairy, 

 beef, swine, sheep, and horse barns. Always caution farmers to cover feed and 

 water troughs before spraying. Do not spray animals with these materials at the 

 dosages suggested. Remove animals before spraying the barns. Do not spray the 

 milk storage room. 



Supplement good sanitation and barn sprays with a spray bait material. Use 2 to 

 4 ounces of dichlorvos (DDVP) or naled (Dibrom) in a mixture of 1 gallon of clear 

 corn syrup and 1/2 gallon of warm water. Apply this from a small tank sprayer to 

 the favorite fly roosting areas. 



Barn foggers using insecticides like dichlorvos (DDVP), pyrethrum, or naled 

 (Dibrom) give a quick kill of flies during the fogging operation (10 to 20 minutes) , 

 but the effect is not lasting. When fly populations become intense, even twice a 

 day fogging fails to provide satisfactory fly control for the farm- -even though the 

 barn is kept temporarily free of flies. .As normally used, fogging does not leave 

 enough insecticide deposit on the animals to protect the cattle from flies when on 

 pasture. Coarse sprays applied to the animals are best for this purpose. 



WEEDS 



As soon as you're through cultivating, catch your breath, then sharpen the hoe and go 

 after the volunteer corn in soybeans while it's still small enough to chop off with 

 one whack. When soybeans quit growing, you may see velvetleaf or jimson weed popping 

 above the beans. If you only have 37 such weeds in a 40-acre bean field, a sharp hoe 

 is usually the most -practical and easiest means of control. 



Don't forget good fencerow weed control . Two miles of fencerow 4 feet wide is about 

 an acre. Five pounds of Dowpon plus a quart of 2,4-D (1 pound active) in 50 gallons 

 of water, applied as a coarse spray, can control both broadleaved and grass weeds in 

 a two-mile stretch. This combination makes an easy and inexpensive control program. 

 You can kill poison ivy in fencerows with amitrole or amitrole-T.
