Weed Control Rating 10/8/73

(Weed Control - predominant species, etc.)
Weed control was generally poor due probably to the cloddy condition of the seedbed. Not cultivated. Predominant broad leafs were
pigweeds, an occasional sunflower and velvetleaf.
Broadleafs few
in number even in no treatment plots. Grasses were predominantly
giant foxtail and fall panicum with foxtail the more prevalent of
the two.
15.
Summary:
(Crop Injury - stand reduction, stunting, chlorosis, etc.)
None observed except in the Modown plots where some leaf burning
occurred and transverse band of puckering across the leaf. This
crinkling persisted through most of the season. Not all plants
affected--35-40%.
This apparently had little influence on the
yield. Injury ratings were 0 = none, 5 = very severe.
16.
Summary:
(Crop Yield)
Yields were quite good considering the rather low plant populations
and poor weed control. 50 plants per harvest area is equal to
14,520 plants per acre. There appeared to be a fairly strong
correlation between plant population and yield.

I cultivation
Broadleaf control excellent.
Grass control very poor especially when
treated in the 3-and 6-leaf stages. Predominant grass was giant foxtail with just a little panicum and crabgrass.
15.
Summary:
(Crop Injury - stand reduction,
stunting,
chlorosis,
etc.)
Treatments 6, 11, and 15 applied in water preemerge and the N sol.
added later at proper stage of growth. Treatment 1 was in N sol.
applied preemerge.
The spike stage treatment was actually at the Ito 2-leaf stage on account of wet fields at the time the corn was in
the spike.
Injury was especially noteworthy when treated in the 6-leaf stage with
considerable burning occurring in the AAtrex-Lasso and Outfox plots
at the 3-leaf stage. Outfox also caused noticeable stunting of the
crop particularly in the 6-leaf stage, but with no loss of plants.
16.
Summary:
(Crop Yield)
Yields were rather erratic with the 2nd rep having the highest yields
quite consistently.
Plot 301 and 302 were on an area that got no N
during the years 1958 through 1968 and the corn appeared to be quite
deficient
in N.
These plots were on the same area as in 1972.

(Crop Injury - stand reduction,
stunting,
«h Lo ros t a , etc.)
No apparent crop injury where herbi 'ide and nitrogen applied preemergent or when corn was in spike stage. All treatments applied
in the 3-leaf and 6-leaf stages cause corn leaf burn.
Leaf burn
was most severe in plots treated with Lasso + Atrazine or Outfox.
Corn leaf burn did not influen~e grain yield.

Summary:
(Crop Yield)
The average yield in the plots were below normal.
Barren stocks
were in all pLocs , Small ears, rotten cobs, and smut infected
stocks contributed to below normal yields.

Summary:
(Weed Control - predominant

_
_
species,
etc.)
Predominant weed species:
sunflower and foxtail.
Some pigweed, giant
foxtail, and lambsquarter.
Weed populations in plot area (which was
not cultivated in 1972) were high. Herbicide rates generally were
higher than recommended for a 1.0% OM soil; weed control was generally
excellent.
Many preplant-incorporated
herbicide plots had some weeds,
vis. foxtail, about 3" from corn rows as a result of soil disturbance
at planting.
Moderate to dense sunflower stands shaded other weeds,
especially foxtail.
15.
Summary:
(Crop Injury - stand reduction,
stunting,
chlorosis,
No injury resulted from higher-than-norma11y-recommended
etc.)
herbicide
rates for a 1.0% OM soil. Modown caused a necrotic band across corn
leaves, being most evident when corn was· 6" to 24tl tall; sunflower
leaves also were injured.
Modown injury to corn and sunflowers was
temporary.
Corn in Rowtate and Rowtate A plots was stunted and slightly
chlorotic, with stunting observed until July.
16.
Summary:
(Crop Yield)
Soil moisture throughout the seaSOn was adequate although plots were
not irrigated.
Thin weed stands did not significantly reduce yields.
Sunflowers markedly lowered yields in Sutan, Lasso, Lorox + Lasso,
Modown, and Modown + Lasso plots.

No corn injury was observed.

Summary:
(Crop Yield)
Grain yields were not significantly different among herbicide treatments.
The untreated control-plot yields were 36 to 46% of herbicidetreated plots. Crop yields were very low, primarily as a result of
compaction from land leveling in 1972.

(Weed Control - predominant

Weed control was quite good on PPI treatments and was generally
unsatisfactory on the PRE treatments, which was probably due to the
absence of effective rainfall for the first 3 weeks following planting. Broadleaf weeds consisted of occasional pigweeds, velvet leaf ,
and a few cockleburs.
Grasses were almost entirely giant foxtail.

Weed control was influenced by a low soybean population resulting from
low-germination seed, poor conditions for germination, and variable
planting depth. Predominant species:
pigweed, crabgrass, and smartweed. Other species:
ivy-leafed morning glory, barnyardgrass, and
foxtail.
Broadleaf and grassy weed control varied, with most herbicides prOViding adequate control to allow combine harvesting.
For the
particular weed species present, marginal control was observed with
Soyex, Cobex, Modown and Basagran in combinations.

Summary:

(Crop Injury - stand reduction,
stunting,
chlorosis,
etc.)
Soybean injury was in part related to low-germination
seed, poor conditions for germination, and variable planting depth.
Leaf injury was
observed on Sencor, Treflan-Sencor, and Vernam plots, with recovery of
Vernam-injured plants but severe stand reduction of Sencor-treated
plots.
The above herbicides, Cobex, and Treflan caused some stand
reduction and stunting.

Summary:
(Crop Yield)
Combine-harvested
yields ranged from 48.2 bu/A to 10.4 bu/A for the
no-treatment plots. Yields generally were correlated
ness of weed control and lack of crop injury.

Plot area was overseeded with alfalfa seed screenings.
Predominant
weed species present were pigweed, velvetleaf, crabgrass, foxtail
ssp., sunflower, and morningglory.
Modown alone did not provide
adequate morningglory control.

Igran + Atrazine applied early post caused a redu ·tion in stand.
Moderate injury was observed from Bladex + Ramrod early post.

Excessive moisture fell in September causing sprout damage to occur
in the head.
Some shattering occurred as a result of sprouting.

stunting,
chlorosis,
etc.)
Some injury was noted on nearly all post treatments.
Atrazine + Ramrod
was most damaging particularly at the spike and 3-leaf stages where
some stand reductions occurred.
It caused severe leaf burning at the
6-leaf stage but killed no plants.
It also caused some apparent delay
in maturity at the 6-leaf stage and 3-leaf stage as did the Outfox
treatment.
Even N solution alone caused noticeable leaf burning at
all stages but the leaf burning apparently caused little or no permanent damage.

Summary:
(Crop Yield)
Yields were good considering
the relatively
low rate of fertilization
and late planting date. PRE treatments averaged 119.6 bu/A, spike
stage - 117.7 bu/A, 3 leaf stage treatments - 114.2 bU/A and 6 leaf
stage treatments 114.7 bu/A. Hand weed plots averaged 118.1 bU/A.

All Igran plots except treatment 24 gave unsatisfactory weed con-
