REGISTRATION REQUESTED FOR VERNAM PLUS TREFLAN 



Registration for Vernam Plus Treflan at rates o£ 2 pounds per acre plus 1/2 pound 

 per acre, respectively, has been requested. 



Why combine two good grass killers? It may be a chance to reduce the possibility of 

 Treflan residue, if this is a concern. Including Vernam might also improve velvet 

 leaf control, but a full rate of Vernam rather than in combination would probably 

 do better. 



When considering combinations, carefully consider your objectives and do not try con- 

 coctions just because combinations are popular. The key consideration is: Will a 

 full rate of one herbicide give better control of specific, weeds than a combination? 



HERBICIDE FOR SUNFLOWERS 



Amiben and Treflan are registered for weed control in sunflowers, and can be used in 

 much the same way as they are used for controlling weeds in soybeans. Eptam is not 

 cleared for sunflowers in Illinois. There appears to be some possibility that sun- 

 flowers may volunteer and grow the following year. It may be best to plan to follow 

 sunflowers with corn rather than soybeans, so that Sutan Plus Atrazine or 2,4-D can 

 be used to control volunteer sunflowers. 



SUTAN PLUS ATRAZINE, OR SUTAN FOLLOWED BY 2,4-D POSTEMERGENCE? 



In most cases, Sutan Plus Atrazine will give better control of smartweed than Sutan 

 alone followed by postemergence application of 2,4-D. Using the combination will 

 also save a trip. If you use Sutan alone, 2/3 of a gallon per acre is suggested, 

 but 1/2 gallon per acre is more commonly used in the combination. 



SILVEX FOR BRUSH CONTROL 



2,4,5-T should not be used around homes, on lakes or ponds, or along ditchbanks. Sil- , 

 vex may be used to control brush or along ditchbanks and for some of the other pur- 

 poses for which 2,4,5-T was previously used. Silvex should give similar results. Check 

 the silvex label for specifics. 



PERENNIAL GRASSES DISCOURAGE ANNUAL WEEDS 



Smooth bromegrass or similar perennial grasses provide excellent, competitive vegeta- 

 tion which will discourage annual weeds such as ragweed, foxtail, and marihuana. This 

 vegetation will also provide excellent protection for the soil and for wildlife. Now 

 is a good time to seed bromegrass in fencerows, along ditchbanks, and in other noncrop 

 areas. Use about 15 pounds of seed per acre. Two miles of fencerow or ditchbank four 

 feet wide is about an acre. 



AATRAM AND BLADEX GRANULES AVAILABLE THIS YEAR 



AAtram is the name of the new Atrazine Plus Ramrod combination now available as 20- 

 percent granules for use in controlling both broadleaf and grass weeds in corn. Weed 

 control in research trials during the past few years has been relatively good, but 

 has varied some with rainfall. Corn tolerance is good. Bladex will also be avail- 

 able as granules this year, again to control both broadleaf and grass weeds.
