Soybean vein necrosis virus – As disease progresses, necrosis of area around veinds occur. Veins often look clear from above and dark from the underside of the leaf. Photo – Albert Tenuta, OMAFRA 2012
A row of soybean sprayed with an overlap rate (twice the labelled rate) of Flexstar GT.
A close up of Guardian injury when applied at the overlap (2X) rate.
A row of soybean sprayed with Guardian at twice the labelled rate (left) compared to an un-sprayed row (right).
From left to right and at the back. Post emergent applications of Lontrel, Banvel II, MCPA and 2,4-D ester. Contrast that to the front where the same four herbicides were applied pre-emergent, but due to no precipitation since application, no injury or weed control has been observed.

Above: note the poor soybean emergence where the previous year corn row existed because the no-till drill could not get the seed deep enough to moisture during the dry 2012 spring planting season
