WEOWNER INSECTS 



uigus gnats will soon appear, attracting the attention of many people. These small, gnat- 

 ke flies develop in wet, decaying organic matter. They get into homes and are nuisances, 

 iside the home, a spray of 0.1-percent pyrethrins applied from a pressurized can will give 

 mporary relief.

1W CLEARANCE 



aisanto has announced new clearances for alachlor (Lasso) . Lasso is now cleared for tank 

 _xing with atrazine (AAtrex) for corn and with linuron (Lorox) for soybeans. The rate 

 .earance for clay soils and soils with over 3-percent organic matter has also been in- 

 leased to allow the useage of 3- and 4-pound rates per acre. Most of the material avail- 

 >le in 1970 will not have this information on the label . 



JACKGRASS 



: you are in quackgrass country (northern Illinois) , it is still not too late to think 

 )out a control program in corn. Atrazine (AAtrex) is the key to quackgrass control. The 

 ite is 5 pounds per acre of the 80 -percent wettable powder. This can be applied as a 

 .ngle application preplant, or as a split application of 2-1/2 pounds per acre in the 

 )ring and 2-1/2 pounds per acre at planting time. 



ZGETABLE GARDENS 



Cultivation and mechanical removal . THIS METHOD IS THE MOST -USED AND SAFEST ONE FOR 

 THE HOME GARDEN. It must be repeated several times through the growing season of a 

 crop. Vacations or absence from the garden is a negative factor for this method. 



Mulching or smothering weeds . This prevents light from reaching the weed seedlings . 

 Several opaque materials used are- -Kraft papers, black polyethylene, ground corn cobs, 

 week- seed- free straw, other fresh vegetation, and composted vegetation. 



, Use of herbicides . This is not practical in small vegetable gardens with several crop 

 species. Different vegetables and weeds vary in their tolerance to herbicides. Thus, 

 ideally , several herbicides should be used. Certain desirable herbicides for certain 

 vegetables remain in the soil longer than one growing season, and may kill or injure 

 different vegetables the following year. Applications must be carefully controlled 

 when a herbicide is used on a small area. The tendency is to apply additional amounts 

 if the quantity measured-out "looks" as though it is not enough. 



my home vegetable gardens are not large enough to make buying several herbicides worth- 

 rile. But Dacthal, Amiben, or Treflan can be used by the home or small commercial gardener 

 10 doesn't want to hand weed but wants to use a herbicide. Dacthal, Amiben, or Treflan are 

 )t the most desirable herbicides for a large planting of an individual species. The most- 

 ;sirable ones for individual vegetable species are listed in Circular 907, Herbicide Guide 

 >r> Commercial Vegetable Growers. 



icthal can be used on snap or garden beans, broccoli, brussel sprouts, cabbage, cantaloupe, 

 lulif lower, collards, cucumbers, eggplant, lettuce, mustard greens, onions, peppers, potatoes, 

 juash, strawberries, sweet potatoes, tomatoes, turnips, and watermelons. Dacthal must be 

 )plied to weed-free soil, because it is a weed-seed germination inhibitor. Best results
