HOMEOWNER INSECTS 



Dark-winged fungus gnats have been present by the thousands for the past week. Com- 

 monly attracted to lights, they can be a nuisance around doorways since they enter 

 the home when the door is opened. 



The larval stage, a maggot, has lived over the winter in dead grass. The over- 

 wintering population was greater than usual because of the long, mild fall in 1971. 

 The sudden warm weather of a week ago caused huge numbers of them to emerge as adult 

 flies all at the same time. The total number has been far greater than in other 

 years. No control measures are suggested other than to spray clusters of these flies 

 with a household aerosol spray. Almost any one of those designed to control household 

 insects will kill these flies. 



WEEDS 



TIME TO APPLY PREPLAN! HERBICIDES 



As a general rule, the closer it is to planting time when herbicides are applied, the 

 better the chances are for weed control. The time of application is more critical 

 for some herbicides than for others. But if you expect 4 to 6 weeks of good weed con- 

 trol from a "4- to 6-week herbicide," it is best to "start the clock" close to plant- 

 ing time. Consider adjusting rates as a possible means of lengthening control, but 

 be sure to stay within the rates recommended on the label. 



Here are some specific timings for preplant herbicides : 



Soybeans : 



Treflan, anytime after January 1. 



Planavin, within the six-week period before planting. 

 Vernam, within the 10 -day interval before planting. 

 Lasso, within the 7 -day period before planting. 



Corn : 



Sutan, within the two-week period before the planting date. 

 AAtrex, within the two-week period before the planting date. 

 Sutan Plus, within the two-week period before the planting date. 

 Lasso, within 7 days of the planting date. 



REGISTRATION CHANGES FOR CHLORO IPC AND SOLO 



The Federal Environmental Protection Agency (EPA) has indicated that they intend to 

 cancel the registration for Chloro IPC and Solo . Manufacturers intend to invoke the 

 appeal process, which may mean that these materials could still be available for use 

 this year. We will make every effort to keep you informed.
