l/8 lb. per acre, may "be applied to corn to within k-0 days of harvest or ensiling, 

 and to soybeans to within 60 days of harvest. Dieldrin, l/h lb., may be applied to 

 corn or soybeans to within 60 days of harvest. Dibrom, malathion and Sevin can also 

 he used on corn for ensilage. 



Bean leaf beetles have been appearing in soybean fields and feeding ex- 

 tensively on the leaves in some areas of the state. Dieldrin or toxaphene as used 

 for grasshoppers will control them as well as the grasshoppers. 



Face flies became much more noticeable this week, particularly in the north 

 1/2 to 2/3 of the state. Infestations may become more severe during the month. 

 DDVP sirup baits should be applied regularly to dairy animals by painting a strip 

 of bait on the animal's forehead with a paint brush. Severely attacked beef animals 

 should be brought into the lot or barn for protection. 



DDVP sirup bait can be further diluted with water so that it will pass 

 through a small hand sprayer. Hold the hand sprayer about 1 foot from the cow's 

 head, and apply 1/5 of an ounce (1 to 2 strokes) to each animal after the morning 

 milking. Losse-housed cattle or beef cattle are more difficult to treat, but good 

 control can be obtained by spraying twice the amount on the sides and backs of these 

 animals. 



For beef cattle, use backrubbers charged with 5.0$ toxaphene, preferably 

 in a mineral oil hase, although a No. 2 fuel oil can also be used. Place the back- 

 rubber where it will get the most use. Allow 30 days between treatment and slaughter 

 of beef animals treated with toxaphene. Do not use toxaphene on dairy cattle. 



Crickets , as predicted earlier, are now migrating and are attracted to 

 lights; in addition, large green leafhoppers which feed and develop on grass crops 

 are also attracted in swarms to lights. 



To aid in reduction of the crickets and leafhoppers that enter the house, 

 apply 2$ chlordane or 1/2$ dieldrin around the foundation of the house and around 

 doorways. Follow label precautions in handling insecticide concentrates. 



Caution : Before applying insecticides, read the labels carefully, and 

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

 eliminate insecticide residue hazards.
