CHEMICAL HAZARD: This product reacts wiIh aluminum to produce hydrogen gas which may 
form a highly combustible gas mixture. Such gas could flash or explode, causing serious 
pe!Sonal injury, H ignited by open flame, spark. welder's torch, lighted cigaretle, or other ignition 
source. Do not mix or store in containers, spray tanks, nUnie tanks, or such systems made of 
aluminum or having aluminum fittings. After dilution with water to spray concentrations, spray 
systems made of, or containing aluminum parts, may be used but Should not be used for 
extended (ovemight) storage. 
EQUIPMENTICONTAINER: Flush all spray equipment With water after use each day. PRELUDE 
EW is corrosive to aluminum. Aluminum spray equipment and aluminum aircraft structures that 
are exposed to spray solution or spray drift Should be flushed thoroughly with water immediately 
after use.

GENERAL INFORMA";lON 
PRELUDE EW herbicide Is a contact burndown herbicide which also provides residual control oj 
many annual grass and small seeded broacleaf weeds. PRELUDE EW controis most small 
annual weeds - both broadeaves and gfP":88S, and suppmlBs perennial weeds by destroying 
green foliage. • 
PRELUDE EW intera<:ts with the plants phoaJilthetic process to pro<lJce supetDDddes which 
destroy the plant cells. PRELUDE EW requires IIdIveIy glOAtno green plant tissue to Mction. 
Thorough coverage of III green foliage Is e.entlal for effective weed control. PRELUDE EW Is 
not IS effective on droufllt-sbelled weeds, or on weeds with little green foliage (I.e., rncrtJed or 
cut weeds. 
RAINFASTNE8S: Because PRELUDE EW Is readily ebeorbed by the weed foliage, rain 
occurring 30 minutes or more after lPPIic:aIIon will have 1liiie, If any, effect on the activity of 
PRELUDE EW.

APPLICATION DIRECTIONS 
Page 9 
PRELUDE EW Booklet 
PRE1348.RS8 - RS-1109928 
Since PREWDE EW provides ctOOfad bumdown or exiF.tIng vegetation, It Is essential to obtain

aps:ilicaltion to large, st.esled. or mown weeds wII usuaIy nIS&It In reduced weed control. See 
. ..•.•..•... for specific application InsIrucions. 
USE OF A NONIONIC SURFACTANT: ALWAYS ADD 8 nonJonIc surfactant with PREWDE EW 
containing at least 50% surface active 1ngi8Clem. The concecltiBtion or surface .:tiYe Ingutdent 
In 8 particularsurfaclant will deterrnk1e how much should be added to lie tank. Refer to the table

50-74% 2 pints 
Less than 50% DO NOT USE 
• 1 pint = 0.125% v/v 
•• Where higher rates of surfactant are desired, additional surfactant may be used. 
Failure to use a nonionic surfactant at recommended rates will result in reduced performance of 
PRELUDEEW. 
DO NOT use crop oil concentrate or any other oil-based additive with PRELUDE EW. 
NOZZLE SELECTION: The use of flat-fan nozzles (either single or twin orifICe design) will result 
in the most effective application of PRELUDE EW. Flood nozzles are generally not as good as 
flat fans since they produce large uneven droplets. The use of ftood nozzles may result in 
reduced weed control due to inadequate coverage.

APPI.ICAnON nMING: PRELUDE EW herbicide should be applied to .merged weeds when 
they are small. Weeds 1" to 6" In height a,. the ...... t to control. Larger weeds may be 
more difficult to control. When weeds have been grazed or mowed, thus removing much of 
the green foliage, allow the weeds to regrow to a height of 2 tJ 4 inches before spraying. 
Similarly, when forage or grain crops have been harvested prior to spraying, weeds present in the 
fl8ld will also have been cut. To allow for adequate green foliage to remain on weeds in this 
situation, raise cutler bars as high as pelSslbl" from the ground to ClIt stubble and weeds at a 
greater height. 
BURNDOWN Or- GRASS COVER CROPS OR VOLUNTEER CEREALS: When using 
PRELUDE EW for control of grass cover crops or volunteer cereals, best results are obtained 
when PRELUDE EW is applied prior to tlilerfng or der boot stege. ThIs Is especially Important 
with a wheat cover crop or volunteer wheat. Treatments made between tll9ring and boot stage 
win erally not rovide complete control. . . . • . .. ... ... gen p ... .. _'_> .. N
