and if full clearance is obtained and the product becomes more readily available, 

 use can be expected to increase. 



Tolerance of commonly grown soybean varieties to Basagran has been good in research 

 studies thus far. And Basagran will control most troublesome annual broadleaf weeds 

 if applied sufficiently early. The label indicates the relative susceptibility of 

 various weed species. Basagran does not control grass weeds, but some control of 

 nutsedge has been noted. 



Glyphosate shows considerable promise for control of both grass and broadleaf peren- 

 nial weeds such as Canada thistle, johnsongrass, and wirestem muhly. The material 

 will be sold under the trade name Roundup. Clearance for use on noncropland is an- 

 ticipated for 1974 and for use on cropland possibly for the 1975 season.
