Homeowners ' Insect Problems 



Correction : Last week a typographical error occurred. The statement 

 said "2 pounds of Aramite 15% wettable powder per gallon..." for spruce spider 

 mite. The recommendation should have been per 100 gallons of water. 



Sod webworms may be a problem in green lawns in those areas where the 

 drought has been severe and most lawns are brown. Unfortunately, the damage may 

 occur when lawns have been kept green by constant woterin^, as moths ten! to con- 

 centrate their egg laying in these lawns. If irrig-iion is discontinued (during 

 vacation time), growth will be retarded and webvorm damage nay be severe. But these 

 lawns may not be noticeably damaged if irrigation is continued. 



To control webworms, apply 2 pounds of actual csrbaryl or 1 pound of 

 diazinon per 10,000 square feet. Use this amount in at least 25 gallons of water. 



Caution to Those Us ing Insecticides 



Before applying insecticides, r^ad the labels carefully and follow all 

 precautions. This will not only insure personal safety, but will also eliminate 

 residue hazards.
