Included in the lima. bean test were ,the standard formU~
lations (R-1856 6E and 100). and the expemmental formulations
EAP4030 and EAP4031. The\design was' a>~andomized block I'
with three replications.
The soybean experiment was a split plot factorial with
two replications.. The 1lla1.n-,plot included'rates of application
and the subplots comJ1'8ted of unincorporated and in- I

The experimental formulations were evaluated for weed
control and· crop toleranoein strawberries, corn, and soybeans.
, ,I
The strawberry experiment included commercial EPTC
(EPtam 6E and 50) and the formulations EAP4001 and EAP4002.
Rates of 3 and 6 pounds 'were used for the"oommercial EPTCbut
only the.lowerrate .was uled for the latter two materials.
All treatments were applied in quadruplicate, in a randomized
block design, 16 days afteJ:I,transplantllll8~'
Included in the corn experiment were commercial EPTC
(EPtam 6E and 50) and experimental formulations EAP4000 and
EAP4005 at rates of 3 and 5 pounds. The experimental design
was a split plot factorial With three replications. The main
plot included rate of appl!ca.tion and tn. subplots consisted
of unincorporated and incorporated treatments of all formulations
randomized completely.
The soybean experiment was similar tlo the corn experiment
in design. Rates of. 4 and 6 pounds were applied in duplicate
for the following formulations: EPtam 6a"and 50, EAP4001
and EAP.4002.

Weed control and crop injury ratings were made periodically

Results
and Discussiop
In tables 1~5 are presented summaries .01' weed control arid
crop injuI"J ratings for the·e.xperimental formulations of R-:1856
and EPTCapplied to the various test crops. For ease of di,scussion
each thiolcarbamate herbicide will be discussed separately.
