Banvel use appears to have increased this year. Reports have started coming in of 

 injury to nearby soybean fields. Symptoms are cupping and crinkling of soybean 

 leaves. Some of the top leaf buds may not open normally. Yields may be affected, 

 but not always as much as you would anticipate by the appearance of the field. 

 There's not much you can do except to get a good book on how to win friends and in- 

 fluence people. 



NOT FOR PUBL I CAT I ON --SPECIAL NOTE TO COUNTY EXTENSION ADVISERS 



Fly control at county fairs : We have modified the following portion of a Purdue 

 Insect Newsletter on this subject to fit Illinois conditions: 



1. Fair officials will need to be sure that manure, garbage, refuse, and soft- 

 drink bottles are removed from the grounds every day. This is a must. 



2. A few days before the fair starts, spray livestock sheds, outdoor privies, empty 

 food tents, and other buildings that may harbor flies with dimethcate (Cygon) , 

 diazinon, or ronnel (Korlan) . A farm crop sprayer, equipped with a lead of hose 

 and a spray gun, can be used for this purpose. Apply the spray to the ceilings 

 and walls to the point of runoff. Most rotary pumps on these sprayers can be 

 adjusted to operate at 250 to 300 pounds of pressure. If the water pressure is 

 good (50 p.s.i. or more), a spray gun that fits on the end of the hose will do 



a good job of applying the insecticide. 



Sprays should also be applied to refuse containers, garbage cans, and the like 

 before and during the fair. A couple of young boys with compressed-air tank 

 sprayers can do this job. 



5. Flies are attracted from great distances to animal waste and food odors. These 

 flies are not killed until they land on a treated surface. For quick knockdown 

 of these incoming flies in animal shelters and other places, use a small electric 

 fogger with oil- or water-base pyrethrum or dichlorvos (DDVP) . These fogs are 

 best applied in the early morning when no people are around. Animals need not 

 be removed, although horses may be frightened by the fog. 



4. Urge that food stands keep some pyrethrum or dichlorvos in a pressurized spray 

 can for quick kill of adult flies. These sprays should be used at night after 

 the stands close. The local health department should insure that all stands 

 maintain the required standards of cleanliness.
