DISEASE & CHEMICAL DAMAGE
Crop to be planted: Potatoes

PROBLEM	RATE OF CHEMICAL APPLIED	SOIL TYPE	CROP TO BE PLANTED	RECLAIM APPLICATION	RESULTS
Sinbar	1 1/2 lb per acre	Sandy Loam	Potatoes	2 qt per acre early spring preplant 1 qt per acre at golf ball size	No detectable damage could be found. Yield: 37 ton per acre was 3 ton/acre better than control
Sinbar	1 lb per acre	Sandy Loam	Potatoes	2 qt per acre June 1st 1 qt per acre late July	Treated acres yielded 34+ ton per acre. Untreated yielded 29.79 ton per acre.
Harmony Extra applied to Wheat	.5 oz per acre	Sandy Loam	Potatoes	2 qt per acre applied thru pivot preplant	Very good potato crop with no sign of chemical damage. 1.79 T/acre increase in yield
Curtail Applied to Wheat	2 pt/acre Curtail	Sandy Clay Loam	Potatoes	Farmer had plowed under chemical & planted - plants quit growing at 8". He then applied 2 qt/acre Reclaim through pivot	Half of field had been affected by chemical. Within one week of application of RECLAIM, line dividing areas could no longer be detected. Yielded 34 ton/acre with good quality
Tordon applied several years earlier with dry land wheat. New pivots installed & potatoes growing in rotation	Unknown	Sandy Loam	Potatoes	2 qt per acre late May 1 qt per acre late July	Spots still detectable but damage confined to small spots. Yields greater than expected & much improved quality. Double application seems to be key for yield enhancement. Single application showed great response on detoxification, but yield not as good as double application
Stinger	4 oz.	Sandy Loam	Potatoes	2 qt per acre	Planted 20 days later - no damage in treated acres with good yield. Untreated areas - not enough crop to dig!
