-4- 





Use 1 pound of actual diazinon in granular form per acre or 1-1/2 pounds of carbaryl (Sevi) 

 as granules. For spraying, use the same amount of actual insecticide per acre, and direct 

 the spray to the upper third of the plant. Aerial applications should be granules, not 

 sprays or dusts. Allow 10 days between treatment and the ensiling of corn when applying 

 diazinon; carbaryl has no waiting period. Commercial applicators may prefer to use para- 

 thion, which provides good control of the corn borer. Parathion has a 12 -day waiting perid 

 between treatment and harvest. 



SOYBEAN INSECTS 



Bean leaf beetles are now appearing and are eating holes in leaves . Do not treat unless 

 the stands are being noticeably reduced. 



Alfalfa weevils and related alfalfa pests are feeding on the leaves of soybeans planted ir. 

 fields where alfalfa was plowed down this spring. No controls are needed. 



FORAGE INSECTS 



Alfalfa weevil needs watching on second-growth alfalfa in central and north-central Illi- 

 nois; also, on the east side of the state to as far north as Kankakee and LaSalle. On the 

 west side of the state, this problem tapers off to the south. If second-crop alfalfa is 

 not growing and is browning and if worms are present, apply one of the weevil insecticides 



STORED-GRAIN INSECTS 



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

 in southern sections . To protect wheat from insect damage, follow these steps: 



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

 storage bin. 



2. Apply a water -base spray of 1.5-percent premium-grade malathion (mix 5 ounces of 50- 

 to 75-percent malathion emulsion concentrate per gallon of water) or a 2.5-percent 

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

 of water) to the ceiling, walls, and floor of the bin. 



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 (1 pint 

 of 50- to 57-percent emulsion concentrate in 5 to 5 gallons of water per 1,000 bushels 

 The dust is best applied on the surface of the wheat in the combine hopper; the spray, 

 as the wheat is augered or elevated into the bin. 



4. Clean out the combine, auger, and other grain-handling equipment. An easy way to cleaj 

 the combine is to discard or feed to livestock the first 2 or 5 bushels that pass 

 through . 



HOMEOWNER INSECT PROBLEMS 



Sod webworm moths can be observed around shrubbery, also on window screens and around ligh'i 

 at night. They are laying eggs for the first -generation larvae, which will be feeding dur 

 ing late June. This generation usually does not do economic damage, as docs the second 

 generation in late July and August. But lawns should be watched for damage anyway. If 

 control is necessary, use carbaryl (Sevin) or diazinon- -either as spray or granules.
