 NOT FOR PUBLICATION: SPECIAL NOTE TO FARM ADVISERS 



Dyfonate (N- 2 790), which is suggested for control of resistant corn rootworms and 

 cutworms in Illinois Circular 899, has not received federal label approval to date. 

 Until label approval is granted, dyfonate should not be used for this purpose. 

 Label approval is not expected in time for use this year. 



Corn borer pupation reached 40 to 50 percent in extreme southern sections, and the 

 first moths emerged this week. Peak egg laying will probably take place in late 

 May and early June in this area. No pupation has been recorded in the central sec- 

 tion as yet. 



Homeoivner Insect Problems 



Bean leaf beetles are damaging newly emerging garden beans. These beetles are 

 green, yellow, tan, or red insects with a distinct black band around the edge of 

 the wing covers. They usually have black spots on their back, but not always. 

 They feed on the undersides of the leaves, eating irregular holes. Sometimes 

 plants are completely defoliated in just a few days. These adults will continue 

 to feed for several weeks. 



Carbaryl (Sevin) , as a spray or ready -prepared dust, is effective. For sprays, 

 use 2 tablespoons of the 50 -percent wettable powder per gallon of water. Repeat 

 treatments may be needed, if more beetles appear. Spray both the upper and lower 

 sides of the leaves for best results. Treatments can be applied up to the day 

 of harvest if needed. 



If you have a history of soil insect problems in your vegetable garden, apply 

 diazinon at 1 ounce per 1,000 square feet before planting . To do this, mix 1/4 

 pint (4 fluid ounces) of 25-percent diazinon emulsion in enough water (usually 

 2 to 3 gallons) to cover 1,000 square feet, then rake into the soil. 



Clover mites are still troublesome in some homes . The cold weather slowed their 

 activity and has prolonged the problem. These mites are tiny, orange -to -black 

 moving specks about the size of the period at the end of this sentence. They are 

 commonly found on window sills, curtains, walls, furniture, etc. --especially on 

 the south and west sides of the building. Ihey move actively about in search of 

 a way outdoors. Pick them up with a vacuum cleaner, or use an 0.1-percent pyre- 

 thrum spray from a pressurized spray can for quick knockdown. Before fall, remove 

 grass, clover, and weeds next to the foundation, leaving a strip of bare soil at 

 least 18 inches wide. Replanting this strip with such flowers as zinnia, marigold, 

 chrysanthemum, rose, or salvia (which do not attract clover mites) will prevent 

 clover-mite problems next year. 



Clothes moths and carpet beetles are looking forward to a summer's feast on im- 

 properly cared for woolens. To protect woolens during the warmer months, follow 

 one or more of these suggested programs: 



1. Dry-clean or wash woolens and place them in clean, plastic storage bags or 

 other insect-tight containers. 



2. Woolens that are not dry-cleaned or washed should be hung in bright sunlight 

 for a full day and brushed thoroughly before storing. Pay particular atten- 

 tion to pocket interiors, cuffs, and folds when brushing.
