2. Persons not equipped with protective clothing . Use: (1) Imidan at 1 pound 

 per acre; (2) a mixture of 3/4 pound of malathion and 3/4 pound of methoxy- 

 chlor per acre; (3) a mixture containing at least 1/2 pound of diazinon and 

 1 pound of methoxychlor per acre; or (4) 1-1/4 pounds of malathion per acre 

 on days when air temperatures will be above 60° F. for several hours after 

 application. Do not harvest for 7 days after treatment with Imidan, methoxy- 

 chlor, diazinon, or mixtures of them. There is no waiting period for mala- 

 thion. Do not apply Imidan more than once per cutting. 



5. Using ground equipment . Apply a minimum of 20 gallons of finished spray per 

 acre, or 4 gallons by air. 



Clover leaf weevil . Larvae of this pest resemble alfalfa weevil larvae. Both 

 are green with a light- colored stripe down the back. One thing is noticeably 

 different- -the head capsule of the clover leaf weevil is brown not black as that 

 of the alfalfa weevil. Also clover leaf weevils are usually larger. In hot, 

 muggy weather they die in large numbers from a fungus which penetrates their body. 

 Alfalfa weevils are not affected by this fungus. 



Fields of red clover examined in the southern one- third to one-half of the state 

 this week indicate that clover leaf weevil larvae are present in considerable num- 

 bers , but the clover is growing away from their feeding damage and no spraying is 

 recommended. 



SMALL GRAIN INSECTS 



Armyworm moths can now be seen at lights at night. These light brown, heavy- 

 bodied moths have a white dot on each forewing. They will deposit eggs on grasses, 

 including small grains, in the most vigorous areas in these fields. Abundance of 

 moths is not known, and it will be three to five weeks before the potential can be 

 determined. 



CORN INSECTS 



Black cutworms . Moths of this pest can also be seen at lights at night. These 

 purplish-brown, heavy-bodied moths are often present at this time of year. As 

 with armyworms, it is difficult to determine potential infestations by moth flight. 



Usually these moths deposit their eggs in low spots in fields, particularly if 

 these spots are wet. Time alone will tell where these moths may deposit eggs this 

 year if present weather conditions continue . 



HOMEOWNER INSECTS 



Many species of aphids are beginning to appear on trees and shrubs, especially haw- 

 thorne and crab apple. The green, soft-bodied plant lice suck the sap from the new 

 leaves, causing the leaves to curl, but rarely do severe damage to the tree. If 

 aphids are very numerous, a spray of either diazinon or malathion will control them. 

 Follow mixing directions on the label. Do not use malathion on canaert red cedar 

 or diazinon on ferns or hibiscus plants. 



Fungus gnats are beginning to appear inside homes now. These small flies develop 

 in wet, decaying organic matter. If they are a nuisance inside the home, a spray 

 of 0.1-percent pyrethrins applied from a pressurized can will give temporary relief.
