*Cultivation is suggested in addition to the VERNAM lO-G 
treatments in fields with moderate or heavy infestations 
of wild cane. 
The above listed broadleaf weeds will be controlled only if 
treatment is made when conditions are favorable for weed seed 
germination and growth.

c ,j 
Existing stands of nutgrass must be turned under and chopped up 
thoroughly before treatment. For nutgrass control VERMAN lO-G 
must be thoroughly mixed into the soil prior to planting. 
cultivation is suggested in addition to VERMAN lO-G treatment in 
fields with moderate or heavy nutgrass infestations. 
GENERAL USE PRECAUTIONS 
VERMAM lO-G should be used only for recommended purposes and at 
recommended rates (do not overdose). 
Applied according to directions and under normal growing 
conditions, YERMAN lO-G will not harm the treated crop. 
Malformation of the primary leaves is not unusual. This condition 
is only temporary and will not affect yields. During germination 
and early stages of growth, extended periods of unusually cold 
and wet or hot and dry weather, insect or plant disease attack, 
the use of certain soil-applied systemic insecticides, imprope,rly 
placed fertilizers or soil insecticides may create abnormal 
conditions that weaken crop seedlings. YERMAN lO-G used under 
these· abnormal condi tions co,€-~ result· in crop inj w;"~" 
VERMAN lO~G is recommended for use on mineral soils only. 
Do not contaminate irrigation water or water used for domestic 
purposes. 
Do not mix VERMAN lO-G with insecticides or fungicides.

DIRECTIONS FOR USE OF VERNAM lO-G 
It is a violation of Federal law to use this product in a manner 
inconsistent with its labeling. 
VERNAM lO-G is a selective herbicide which is mixed 
(incorporated) into the soil, except where note~ under 
RECOMMENDATIONS, for control of weeds listed on this l~bel. 
VERNAM lO-G controls annual weeds as their seeds germinate by 
interfering with normal germination and seedling development. It 
does. not control established weeds. All weed growth and crop 
stubble should be thoroughly worked into the soil before 
treatment. 
VRNAMIOG.doc 6/28/93

APPLICATION DIRECTIONS 
The soil should be well worked and dry enough to permit good soil 
mixing (incorporation). Use granular applicators designed to 
hcondle herbicide granules. Calibrate the applicator according to 
the manufacturer's directions prior to use and check frequently 
during application to be sure equipment is working properly and 
distributing the granules uniformly. Avoid overlaps that will 
increase dosage above recommended limits. When using certain 
broadcast applicators, a splash pan is needed to spread the 
granules and avoid concentration of the material in narrow bands. 
Broadcast applications before planting may be made by airplane. 
INCORPORATION DIRECTIONS 
with soil incorporation applications, VERNAM 10-G must be mixed 
(incorporated) into the soil immediately (within minutes) after 
application to prevent loss of herbicide. Whenever possible, 
application and incurporation should be done in the same 
operation. 
SOIL MIXING (INCORPORATION) BEFORE PLANTING: Use power-driven 
CUltivation equipment set to cut to a depth of 2 to 3 inches OR a 
tandem disc set to cut to a depth of 4 to 6 inches operated at 4 
to 6 mph, followed by a spike-tooth harrow or some other leveling 
device which extends beyond the ends of the disc. For thorough 
mixing, disc in two different directions (cross disc). Prior to 
the second discing, raise the disc to prevent cutting deeper than 
4 to 6 inches. 
SOIL MIXING (INCORPORATION) AFTER PLANTING: Use po\t~r-driven 
CUltivation equipment set to cut to <'. depth of 2 i.nches OR on 
d' ~ D 
I 
J 
light soils only, Iground-dr~en ·tille~~ (rolling .. cultivators, .~ .. \ 
rotary hoe, row ~heels, etc) set to cut to a depth of 1-1/2 
.~ .; 
inches an~ oper~ted at 6 to 8 mph. When incorporating after 
planting, carF. must be taken not to disturb the crop seed or 
seedlings. Adjust tines or blades of incorporation equipment so 
they are noe directly over the drill row. 
PLANTING - SOYBEANS, PEANUTS 
Do not plant seed deeper than 2 inches. For VERNAM 10-G 
applications made before planting, seeding can be done 
immediately or it may be delayed up to 10 days. If it is 
necessary to wo~~ the soil following application and incorpor­
ation, but before planting, do not work the soil deeper than the 
depth the herbicide was incorporated. To avoid removing VERNAM 
10-G from the row (with loss of weed control in the row) do not 
move or shape soil after treatment, such as by planting in deep 
furrows.

RECOMMENDATIONS 
These recommendations are given in terms of broadcast (over-all) 
rates VERNAM 10-G per acre. For band or row applications, reduce 
broadcast rates proportionately depending on band width to be 
treated and row spacing. 
PEANUTS: 
VERNAM 10-G may be applied before planting, or immediately after 
planting. When incorporatL g after planting, care must bE> taken 
not to disturb the seed. Broadcast Rates Per Acre--20 pounds on 
sandy (light) soils, 25 pounds on sandy loam to clay loam (medil.:m 
to heavy) soils. 
SOYBEANS: 
For Soybeans Grown in Midwestern, ~rorth Central and Northeastern 
states: VERNAM 10-G may be applied before planting by broad­
casting 20 pounds on sandy (light) soils, or 25 pounds on sandy 
loam to clay loam (medium to heavy) soils. 
VERNAM 10-G may also be applied at planting or immediately after 
planting by broadcasting 20 pounds on sandy (light) soils, 25 
pounds on sandy loam to clay loam (medium to heavy) soils, and 30 
pounds on clay (heavy) soils. WhE'. incorporating after planting, 
care must be taken not to disturb the crop seed or seedlings. 
For Soybeans Grown In The Southeastern States including North 
Carolina, South carolina, Georgia, Alabama, Florida, and Eastern 
Tennessee (Tenn. River East): VERNAM 10-G may be applied before 
planting or immediately after planting. For appli~ations made 
before planting, do not plant in' deep furrows or .. woe shanks or 
other devices ahead of plantdr· which bring up untreated soil to·~"~" , .. "- . 
the surfac;;e. For furrow planted soybeans, apply VERNAM lO-G 
immediately after planting in bands over the row and incorporate 
with row wheels only. When incorporating after planting, care 
must be taken not to disturb the crop seed or seedlings. 
Broadcast Rates Per Acre--20 pounds on sandy (light) soils and 25 
pounds on sandy loam to clay loam (medium to heavy) soils. 
In The Midwest and North Central States Only: VERNAM 10-G may 
also be applied to the soil surface immediately after planting 
I without mixing it into the soi: by broadcasting 30 pounds on 
sandy (light) to clay (heavy) soils. This application method will 
not control nutgrass, Johnsongrass from seed, wild cane or 
velvetleaf. Also, rainfall of at least one-half inch in one rain 
is necessary to carry the chemical down to the germinating weed 
seeds. One or more light rains are not sufficient. Poor weed 
control will result if sufficient rain does not occur within 7 
d~ys after application. If sufficient rainfall does not occur, OR 
if weeds have emerged, rotary hoeing or standard CUltivation 
should be done before weeds become well established.

For Soybeans Grown in the ~outhwestern States Including Arkansas, 
Louisiana, New Mexico, Texas, Oklahoma, Mississippi and Western 
Tennessee (Tenn. River West): VERNAM lO-G may be applied before 
planting. When incorporating at or after planting, care must be 
taken not to disturb the crop seed or seedlings. Broadcast Rates 
Per Acre--20 pounds on sandy (light) soils, 25 pounds on sandy 
loam to clay loam (medium to heavy) soils and 30 pounds on clay 
(very heavy) soils. 
NOTE: If beds are made prior to planting soybeans, VERNAM lO-G 
may be applied 1n a band immediately ahead of the bedding discs 
set to cover the VERNAM lO-G with 3 to 4 inches of soil. If bed 
levelers are used before planting soybeans, make the beds higher 
to compensate for leveling, so 2 to 3 inches of soil remains over 
the treatment after the planting operation is done. 
CULTURAL PRACTICES FOLLOWING APPLICATION 
VERN}~ 10-G is not persistent in the soil, and susceptible ~ceds 
germinati~g later during the growing season may not be 
controlled. Shallow cUltivation may be necessary to control these 
late-germinating weeds. Do not cUltivate deeper than the depth of 
the herbicide incorporation. Recommended preemergence or post­
emergence herbicides may be applied over the top of preplant 
incorporated applications of VERNAM lO-G when necessary to 
control weeds resistant to VERNAM IO-G.
