3. For quick knockdown at cookouts or outdoor parties, use either 0.1-percent 

 pyrethrin or 0.5- to 1-percent dichlorvos (DDVP) as an oil- or water-base space 

 spray. Spray the mist lightly beneath tables and chairs and into the air for a 

 few feet around the area. If the mosquitoes are numerous, it may be necessary 

 to spray beforehand as well as once or twice during the event. 



4. When entering mosquito- infested areas, use a repellent on the exposed parts of 



the body. One of the most effective mosquito repellents is DEET (diethyl toluamide). 



WEEDS 



NEW CLEARANCE 



Solo (naptalam-plus -chlorpropham) -plus-Lasso (alachlor) recently received a federal 

 clearance for use as a tank-mix combination for preemergence weed control in soybeans. 

 The combination will provide better grass control than Solo alone, and better broad- 

 leaf weed control than Lasso by itself. The treatment had been cleared for use in 

 some neighboring states before the federal clearance was announced. Illinois does not 

 register herbicides or combinations until they have received federal registration. 



HERBICIDES NOT CLEARED 



Naptalam-plus-dinoseb (sold as Dyanap, Ancrack, and Kleenkrop) is not cleared for use 

 as a salvage postemergence treatment for soybeans. The Federal Pesticide Act of 1972 

 states that herbicide treatments not applied according to label are illegal, and il- 

 legal treatments are subject to fine.
