HERBICIDAL WEED CONTROL IN CORN, PEANUTS, SOYBEANS AND GRAIN SORGHUM 1962
By R. L. Smith


CORN: Cokers 67 corn was planted April 17 on Carnegie fine sandy loam soil
w~Eh had been fertilized with 600 pounds of 4-12-12 prior to planting. Treat.
ments using Trifluralin, R-1910 and Casoron were incorporated with a rotivator
prior to planting. Other chemicals, as shown in the table, were applied as
preemergence treatments on the day after planting. Four plots of each treat-
ment were included. The supply of moisture was very good at planting time, but
declined very rapidly with severe dry weather as the corn grew to maturity.

Treatments and rates of material giving good control of weeds and grass
were: Simazine 3 pounds, Atrazine 3 pounds, R-1910 3 pounds incorporated,
Karmex 2 pounds, Falone 2 pounds, Fenac 1 pound, Premerge 9 pounds,
Sinox-PE 9 pounds, Sinox-G 9 pounds and Premerge -4-1/2 pounds plus 2,4-D -
1 pound. Trifluralin was very toxic but gave lasting control of weeds and
grass. FW-925, Falone, Fenac and the dinitro compounds were slightly toxic
in seedling stage, but the corn recovered. R-1970 3 pounds incorporated was
superior to 3 pounds sprayed preemergence.

Uniform stands of crabgrass, watergrass and barnyard grass, Florida
pursely and red weed (Melochia corcorifoliar) were present. Other weeds
present were cockleburr, rough morning glory (Thyella tamnifolia), night
shade, coffee weed and pig weed.

PEANUTS: Dixie Runner peanuts were planted May 17 on Red Bay fine sandy loam
soil. The population of crabgrass, watergrass, Florida pursely and red weed
were uniform. Other weeds present were: cockleburr and coffee weed. The
supply of moisture was low at planting, and the dry weather continued. However,
a stand was finally obtained. Thirty-six treatments were applied preemergence
one day after planting with the exception of the materials Trifluralin, R-1607,
Tillam and Casoron which were incorporated prior to planting. In addition,
12 treatments, as shown in the table, were applied at emergence or "cracking
time".

The following materials were toxic: Randox T 10 Iounds (very toxic),
Prometryne 1-1/2 and 3 pounds, Ametryne 1-1/2 and 3 pouA2, FW-925,
Falone 3 pounds, Chloro IPC both granular and liquid, Alanap 3 and Loro -
2 pounds. Peanuts recovered where Prometryne 1-1/2 p unds, Amyhe /2
pounds, Falone and Lorox were used. "Yt? /

Excellent weed control was obtained with: all dinit 'copounds, alone -
1-1/2 and 3 pounds, Prometryne 3 pounds, FW-925, Trifluralhn --2-ad
pounds, R-1607 -J pounds, Tillam 3 pounds, Ametryne 1-1/2 and 3 pounds,,
Dacthal 6 pounds, CIPC 8 pounds, Randox T 10 pounds, Amiben 3 pounds,
Lorox 2 pounds and Sesone 3 pounds.,

Combinations of dinitro at 1-1/2 pounds with Amiben, Sesone, Falone,
Fenac, Tillam, Lorox and Butyrac applied at "cracking time" at rates shown





-2-


in the table gave good to excellent control of weeds. Applications of dinitro,
Lorox and Falone at "cracking time" gave good results but not quite as good as
in combination. The foliage was burned by these sprays but the plants
recovered

SOYBEANS: One-half of this experiment was planted in 38" rows and the other
half was planted with a grain drill. Three replicates of each of 50 treatments
were included in each part of the test on Carnegie fine sandy loam soil.
Florida WH 57-1 beans were planted and a good stand was obtained with an ex-
cellent supply of moisture. Severe dry weather occurred during the growing
season. A power-driven rotary hoe was used to incorporate materials indicated
in the tables. The incorporated treatments in the section planted with a grain
drill were disked once after incorporation with a rotary hoe. This disking
was necessary to remove row furrows in this section.

Uniform stand of crabgrass, watergrass, barnyard grass, red weed and
Florida pursely were present. Cockleburr, coffee weed, rough morning glory
and night shade occurred irregularly.

There was a total loss of stand in the section planted in rows where
the materials were incorporated with a rotary hoe. The stand on these treat-
ments was much better where disking in broadcast plantings was done following
the rotary hoe. The probable reason is that the rotary hoe did not stir the
area of the row where the beans were planted. The hoe had been used for
cultivating young beans in rows and the tines were not moved leaving the
space immediately over the row undisturbed. Prometryne and Ametryne 3
pounds damaged the stand in both sections of the experiment. Treatments caus-
ing slight damage were: Lorox 4 pounds, G-34,696 and Weed Beads (27 pounds).
Use of 2,4-D derivatives caused some toxicity but the beans recovered.

Treatments giving good to excellent control without any ill effects were:
Amiben 4 pounds, Lorox 3 and 4 pounds, Prometryne 1-1/2 pounds,
Ametryne 1-1/2 pounds, Karmex 2 pounds, Dacthal 6 and 8 pounds,
combinations of Premerge 1-1/2 pounds plus Butyrac 1/2 pound, Butoxine
Amine 1 pound and Ester 1 pound and MCPB 1 pound, Premerge 4-1/2
pounds, Randox 6 pounds, Falone h4-E 1 pound, CIPC 6 pounds, Sinox-G -
6 pounds, M-1693 6 pounds and Weed Beads 18 pounds.

Herbicides were more effective with broadcast or grain drill plantings
than with row plantings. Shading by the beans is quicker and more complete
with broadcast stands of beans. This brings up the possibility of using
smaller amounts of herbicides for broadcast planting. Previous experiments
indicate that yields from broadcast plantings of beans are equal to yields of
row plantings.

GRAIN SORGHUMt Grain sorghum variety R-12 was planted June 25 on Ruston fine
sandy loam soil, The stand on the check plots was good. Severe dry weather
occurred as the growing season progressed. All materials were applied as
preemergence treatments except one treatment with Simazine which was applied
when sorghum was in the spike stage. Four replications of each treatment were
included, the rates and data are as shown in the table.

Stands af crabgrass, watergrass and Florida pursely were present. Sand-
spur and nutgrass occurred irregularly.

Good results were obtained at rates shown in the table with the following
materials: Simazine, Atrazinej Propazine, Premerge, Premerge plus Butyrac,
Randox T, Weed Beads, M-2025, Amiben and Sinox-G.

R-1910, CIPC and EW-925 caused a complete loss of the stand. Stand damage
from use of N-3291, Lorox, Diphenamid, Sesone and Dacthal was 0O, 50, 50, 50
and 65 percent, respectively. Other materials caused small but negligible
damage to the stand as shown in the table.
