Good housekeeping practices will help reduce the number of these insects. Clean 

 the house frequently to prevent lint and hair from accumulating, especially around 

 radiators, baseboards, heating vents, and closets, as well as beneath large furni- 

 ture and other hard- to -get -at places. If such places become infested, a light ap- 

 plication of a 0.5-percent diazinon spray will insure protection. 



WEEDS 



STALE-SEEDBED WEED CONTROL — A MODIFIED PIGGYBACK TREATMENT 



A stale seedbed is one that has been prepared before planting and then left undisturbec 

 during planting. Treflan or Planavin is usually applied as a preplant treatment, whicl 

 is incorporated sometime before planting. The weeds that were not controlled by the 

 preplant chemical will emerge. At planting or shortly afterward, a contact herbicide, 

 such as Lorox (linuron) , is applied to control the growing weeds, but the seedbed is 

 not disturbed. 



Lorox (linuron) is the contact herbicide usually chosen, because it gives some residua] 

 control in addition to the contact control. Adding a surfactant greatly enhances its 

 contact action. Paraquat has also been tried, but some weeds still emerge after plant- 

 ing; also, paraquat has no residual action. 



For drilled soybeans, the stale-seedbed concept is one of the most -promising practices 

 for weed control. This concept is really a modified piggyback idea. Two herbicides 

 are applied at different times. Lorox and Chloro-IPC have been cleared for use in a 

 piggyback treatment with Treflan. Dynap--a combination of dinitro plus Alanap 

 (naptalam) --is also being sold for use as an overlay treatment with a grass-control 

 herbicide, such as Treflan. 



SOYBEAN HERBICIDE COMBINATIONS 



There are several new names in soybean herbicides. Many of these are herbicide com- 

 binations that may provide control of more weeds or may permit use on a greater di- 

 versity of soil types. Some of these combinations are: 



SHAMROX—Dacthal (DCPA) plus Lorox (linuron) 



SOLO- -Alanap (naptalam) plus Chloro-IPC (chlorpropham) 



NORABEN--Herban (norea) plus Amiben (chloramben) 



DYNAP- -dinitro (dinoseb) plus Alanap (naptalam) 



DYNARAM- -dinitro (dinoseb) plus Amiben (chloramben) 



AMILON- -Amiben (chloramben) plus Lorox (linuron) 



Tank mixes of Lasso (alachlor) with Lorox (linuron) or Chloro-IPC (chlorpropham) have 

 also been cleared. Chloro-IPC is added primarily for smartweed control, while Lorox 

 will control smartweed and many other broadleaf weeds for which Lasso does not provide 

 adequate control.
