For soybeans or corn for grain, use 1 to 2 ounces of dieldrin or 1 l/2 pounds 

 of toxaphene per acre. Allow 60 days to elapse between application of dieldrin and 

 harvest. If corn or soybeans are to be used for ensilage, hay or pasture, use sevin 

 or malathion with a 7-day interval between application and harvest. Diazinon can be 

 used on ensilage corn with a l4-day interval between application and harvest. 



Fall armyworm moth flight continues and late fields in pretassel stages have 

 shown some worm damage in the whorl. This has occurred throughout the state. In gen- 

 eral, damage has been of minor importance. 



Sod webworm damage to turf may occur any time from now on. But do not con- 

 fuse this damage with other similar problems as the after effects of dry weather. 



Several insecticides can be used to control webworms in lawns: 1/4 to 1/2 

 pound of sevin, l/4 pound of diazinon, l/8 pound of DDT, or l/2 ounce of dieldrin can 

 be used for each 2,500 square feet of surface. Where birds are extremely abundant, 

 it would be best to use sevin. 



Stable flies are particularly bad on cattle; cattle fight flies by stamping, 

 kicking, and switching. It was quite noticeable this week. Stable flies resemble com- 

 mon house flies but are found most commonly on the legs and undersides of the cattle. 

 They pierce the skin with their needle-like mouth parts and suck blood. 



For dairy cattle , apply 2.0$ ciodrin, 1.0$ DDVP or 0.1$ pyrethrin in a min- 

 eral oil base. Spray at the rate of 1 to 2 ounces per animal per day or as often as 

 needed. Be sure to spray the undersides and legs. 



For beef cattle , apply a 0.5$ toxaphene water diluted spray at 1 to 2 quarts 

 per animal every three weeks. Thorough coverage of the animal is important for effec- 

 tive results. Allow 30 days to elapse between treatment and slaughter when using tox- 

 aphene. Ciodrin 2.0$ in oil applied two or three times a week with an automatic 

 sprayer can also be used effectively. 



Face fly populations remain low. 



For dairy cattle , brush 0.2$ DDVP in corn syrup on the foreheads each morn- 

 ing. Use a DDVP concentrate and mix with corn syrup as needed. Commercial ready- 

 to-use baits may be ineffective. Dairymen who wish to try a new remedy for face flies 

 should obtain a 2.0$ ciodrin oil solution. Apply at the rate of 1 to 2 ounces per 

 animal as needed, but 2 to 3 applications per week should be adequate. Ciodrin has 

 federal label approval for use on dairy and beef cattle. 



For beef cattle , use a rubbing device, preferably constructed of cloth, bur- 

 lap or canvas, and keep it well saturated with a 5-0$ toxaphene-oil solution. Locate 

 these devices surrounding salt, mineral or watering units to insure their use. 2.0$ 

 ciodrin in oil can also be used on beef cattle conveniently from an automatic sprayer. 

 Apply 1 to 2 ounces per animal 2 to 3 times per week. Allow 30 days to elapse between 

 treatment and slaughter when using toxaphene. 



Salt blocks, mineral supplements or other feeds containing either pheno- 

 thiazine or ronnel are not recommended for face fly control even though they may give 

 good control of horn flies. Even though ronnel, not phenothiazine when fed to beef
