cannot "be used for livestock feed and should not be applied adjacent to dairy 

 pastures or hay crops. 



Black cutworm moths normally deposit eggs in overflow areas or low, 

 damp spots in fields. This year there are low, damp spots in most cornfields, 

 and we may have a peculiar condition. The moths now present may have been scat- 

 tering a few eggs over wide areas in many fields or concentrating them in spots. 

 If they are concentrating their egg-laying, it may be too wet in the usual low 

 spots and they may lay eggs in higher, ordinarily well-drained spots that this year 

 are remaining wet . Such spots might never before have been bothered with black 

 cutworms . 



Since little corn is up to help us appraise the situation, carefully 

 examine areas in fields if you find cut plants, which may occur almost anywhere 

 this year. 



The Homeowner's Present Insect Problems 



Aphids may soon appear on cabbage and related cole crops as well as on 

 tomatoes; they transmit certain tomato diseases. Apply malathion to control them. 

 Watch for white cabbage butterflies around cabbage and related plants. These are 

 the adults of the cabbage worms . Early application of carbaryl (Sevin) when the 

 worms are small makes control easy. 



Bagworms have begun to hatch in southern Illinois and will soon hatch in 

 central Illinois. As soon as you see lots of the tiny bags on trees, apply 

 carbaryl, diazinon, lead arsenate or malathion. The label lists plants that will 

 not tolerate the insecticide. Follow these precautions. 



European pine shoot moth is damaging on some pine shrubs and trees. 

 Small brown larvae with black heads are boring into the base of the needles on new 

 growth of pines, especially Mugho. For control, use a spray containing 3 table- 

 spoons of 25 percent DDT per gallon of water. This application may be late for 

 maximum control. Apply again in mid- to late June, when the next generation of 

 larvae appears . 



Chiggers may be real scratchers very soon. This wet, damp weather favors 

 their development. Use a good chigger repellent around the ankles and waist if 

 you are going on an outing. Upon return, take a good, hot, soapy shower or bath. 

 These precautions will almost eliminate chigger bites. 



Caution to Those Using Insecticides 



Before applying insecticides, read the labels carefully and follow all 

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

 residue hazards .
