(Weed Control - predominant species , etc.)
Prior t o planting, the plot area was over seeded with alfal fa and red
clover seed screenings . Equa l quant ities of rough and s mooth pigweed
made up the pigweed population. A spa r se velvet leaf population did
not warrant a rating. The foxtail popula t ion was equally divided among
s pec ies of giant, yellow, and green fo xt a il.

(Crop Injury- stand reduction, stunting, chlorosis, etc.)
Although s i gnificant crop inj ury was noted in some treatment s , the

Summary:
(Crop Yield)
Crop y i eld was r educed becaus e of the low amount of rainfall received.

(Weed Contro l - predominant species , etc.)
Weeds were essentially 100% velvet1eaf . Grass control was exce llent.
Preplant treatments clearly gave the best weed control with the
except ion of PROWL in the preemerge treatments. This material was
out·standing in 1976.
15.
Summary:
(Crop Injury- stand reduct i on, st unting, chlorosis, etc . )
Crop injury was only very s l ight if it exis t ed at all.
16 .
Summ3ry:
(Crop Yield)
Crop y i e lds were quite variab le and generally low because of an unfavorable
season for corn and the choice of hybrid for th e type b f season that deve loped .

Essentially 100% ve l vet leaf. Inadequate rainfall resulted in l ittle or no
early control of seeds, particularly in the plots treated b efore pl ants
emerged, so all plots were cul tivat ed June 23. Plots were reasonably clean

Summar:i:
(Crop Injury- stand reduction, stunting, ch l orosis, etc.)
There was very lit tl e, if any, crop injury because of inadequate rainfa ll
fo llowing treatment to activate the herb ic ides . Some stands were a litt l e
thin because of plant er malfunction .
16.
Summ.ny :
(Crop Yi e ld)
This was a f airly good tes t in sp ite of the variations in stands and again
t he preplant treatments were clearly supe rior for weed control .

Summar~:
Delay of rainfall after planting r educed weed emergence , bu t also prevented
incorporation of chemical s by rainfall. The dry summer helped the effect ive ness of post treatme nts. PPI trea tments were effect ive.
Summary : (Crop I njury- stand reduction, stunting, chlorosis, etc . )
No injury notes were taken as no injury was evident until the application
of early post treatments.
Neighborhood aerial spraying of wheat {ields with 2,4-D or banvel caused
some overal l injury .
Overa ll stand was irregu l a r because of faul t y seedbed preparation and
planter adjustment . No r e duction of stand was apparent b ecause of herbicides.
16.
Summary :
(Crop Yield)
Crop yield was fair considering the dry season .
36
Stands differed among plots .
