Azinphosmethyl has a 21-day waiting period between treatment and harvest; carbopheno- 

 thion, a 7 -day waiting period. Do not feed soybeans sprayed with these insecticides 

 as forage to dairy cattle or livestock being fattened for slaughter. 



Potato leafhoppers , both nymphs and adults, are numerous in some alfalfa fields. They 

 reduce hay yields as well as the quality of the hay by lowering the content of Vitamin 

 A and protein. These leafhoppers cause a yellowing of second- and third -crop alfalfa. 

 Treatment is indicated if swarms of these small (1/8 inch), green, wedge-shaped in- 

 sects are observed during cutting or on the new growth of the second crop. Use either 

 carbaryl (Sevin) or methoxychlor, at 1 pound per acre. When using methoxychlor, allow 

 7 days to elapse between treatment and harvest. There is no waiting period for carbar> 

 (Sevin) . 



STORED-GRAIN INSECTS 



Stored-grain insects are lying in wait for the wheat harvest, which is just around the 

 corner in the southern part of Illinois. To protect stored wheat from insect damage, 

 follow these steps : 



1. Sweep-up and clean-out all the old grain, chaff, and other debris from inside and 

 around the outside of the storage bin. Also clean-out the combine, auger, and 

 other grain -handling equipment. You can clean the combine by discarding or feed- 

 ing to livestock the first 2 or 3 bushels that pass through. 



2. To the ceiling, walls, and floor of the bin, apply a water-base spray of 1.5- 

 percent, premium-grade malathion (mix 3 ounces of 50- to 57 -percent, malathion - 

 emulsion concentrate per gallon of water), or a 2.5-percent methoxychlor spray 

 (mix 14 ounces of 25 -percent, methoxychlor -emulsion concentrate per gallon of 

 water) . 



3. If the wheat is to be stored for a month or longer, treat it with a premium-grade 

 malathion dust (40 to 60 pounds of 1 -percent dust per 1,000 bushels), or spray 



(using 1 pint of 50- to 57-percent emulsion concentrate in 3 to 5 gallons of water 

 per 1,000 bushels). The dust can be applied best to the wheat when it is in the 

 combine hopper; the spray, as the wheat is augered or elevated into the bin. Give 

 the surface grain a light treatment after all the grain is in the bin. 



4. Re inspect the grain once each month to be certain that your control program is 

 effective. Last year some stored wheat that had been treated with premium-grade 

 malathion became infested with Indian meal moths by mid- to late August, indicat- 

 ing a possible resistance of this insect to malathion. 



Use malathion as directed . A report has been received that one large grain company 

 refused to buy wheat treated with malathion because of the objectionable odors. Be 

 sure the malathion you use is labeled for use in stored-grain insect control, and, 

 therefore, is of the low-odor type. Do not overdose, and do not apply malathion if 

 you plan to ship the grain within a week or two. Apply a grain fumigant for quick 

 kill, if insects are present and the grain is to be shipped soon. 



HOMEOWNER PROBLEMS 



Sod webworm moths appeared this week around lights and in tall grass and shrubbery. 

 They fly a zig-zag pattern over lawns during the early evening, laying eggs that
