SOYBEAN INSECTS 



Seed com maggots continue to damage a few fields of late -emerging soybeans. Skips 

 appear in the row of damaged fields. Small, white maggots can usually be found in- 

 side the damaged seed. It is too late to control the maggot when damage is observed. 

 The warm, wet weather should help slightly damaged plants to recover. 



HOMEOWNER INSECT PROBLEMS 



Millipedes are moving into homes from shrubbery beds, lawns, storm 

 sewers, and nearby wasteland with a heavy trash cover. These mi- 

 grations are somewhat earlier than normal (August and September), 

 and are probably the result of recent heavy rainfall. It is usually 

 the cool weather that causes them to seek shelter in homes. These 

 brown or grey, hard-shelled, slow-moving, worm- like animals have 

 two legs per body segment. They are sometimes called "thousand- 

 leggers," and will curl up in a tight coil when disturbed. Although 

 harmless, they make a general nuisance of themselves in the home, 

 Millipede clustering in basements and garages. 



In cases of heavy migrations, spray lawns and shrubbery beds with carbaryl (Sevin) , 

 diazinon, or trichlorfon (Dylox) . This provides a barrier zone in which the millipedes 

 are killed, and prevents them from gaining access to the house. If migrations persist, 

 repeat the treatment in a week or two. For minor problems, spray shrubbery beds and 

 a 5- to 4-foot wide area around the foundation of the house for control. The general 

 lawn treatment will also control sod webworms and leafhoppers, but it is ineffective 

 against grubs. 



Picnic beetles are becoming numerous at the present time. These black beetles with 

 four yellow spots are attracted to food odors and decaying or overripe fruit and vege- 

 tables. They are commonly found around garbage cans and on window screens. 



For control in home yards, harvest fruits and vegetables before they become overripe. 

 Dispose of any spoiled produce. To kill the adult beetles, spray with malathion, 

 diazinon, or carbaryl (Sevin) in and around garbage cans. Spraying shrubbery and tall 

 grass with the same insecticides before a cookout will greatly reduce the number of 

 these beetles. Follow directions on the label. Check plants that may be injured if 

 sprayed with the insecticide you are using. Either 0.1-percent pyrethrin or 0.5-percent 

 dichlorvos (DDVP) spray in pressurized cans will give a quick knockdown of beetles that 

 suddenly move into an area. 



WEEDS 



Wet is the word from all over the state. If you did not complete your cultivation 

 before the rains, corn and beans are likely to be too large in many fields to finish 

 cultivating when it dries up. 



2,4-D can still be helpful in many late-maturing cornfields. So far, fewer farmers 

 have reported 2,4-D injury to corn this year than last. A few areas, however, have 

 reported rather severe injury --some where 2,4-D was sprayed July 5 and 4 during 

 exceptionally hot and humid weather followed by wind. 



Avoid spraying 2,4-D during such hot, humid periods. Be sure application rates are 

 correct. We suggest 1/6 lb. /A., low-volatile ester; 1/4 lb. /A. , high-volatile ester; 

 or 1/2 lb. /A. of amine. (If you're using a 4 lb. /gal. concentrate, 1/4 lb. is a half 

 pint and 1/2 lb. is one pint.)
