Command Injury to Cheniere Rice

Below are three photographs taken in the same field where Command had been applied with a ground rig.  The applicator made one pass on each end to provide a turn around area.  Then he started making linear passes from the east side of the field working his way to the west.  In the top photograph the clearly damaged area on the right is the first pass.  The green area is the east half of the field.  The bare area across the top of the picture is the west side of the field.  We could not determine if there was some extremely odd mixing problem that caused a light to normal dose to be applied at the beginning then a heavy rate later as more product mixed or if there was some sort of mechanical malfuntion in the spray rig.  It does have electronic spray controllers so I suppose it is possible that caused the strange injury pattern.  The severly damaged area will have to be replanted.  This is the most severe Command injury I have ever seen.

Last week we were called to a hybrid rice field where there were issues with stand loss.  We could not determine any specific cause, but did note the presence of thrips on nearly every plant.  While the number was fairly large there presence was not especially alarming to me because I have always seen them on seedling rice.  The field was treated with Dermacor which is not expected to control thrips.  We also suspected some seedling disease.  In the past we planted at high enough seeding rates to compensate for seedling loss, but the low seeding rates of hybrids magnifies any stand loss.  Without a definitive cause we could only make a couple of suggestions; apply an insecticide or add some starter nitrogen.  I followed up with the farmer who said he chose to add starter fertilizer and while the stand is still thin the seedlings are growing better.  Nearby crawfish ponds may have had some influence on the decision.
