ABSTRACT
Background: Enlist E3™ soybean is tolerant to 2,4-D, glyphosate and
ammonium-glufosinate and were developed for effective management of
herbicide resistant weeds such as glyphosate Herbicides, even being
selective, can cause damage to crop metabolism, affect growth and
development and interfere with seed physiological quality.
Objective: The aim of this research was to evaluate the physiological
quality of Enlist E3™ soybean seeds submitted to herbicide application.
Methods: The field trial was carried out in a randomized block design
with four replications. The treatments tested were 2,4-D choline +
glyphosate, 2,4-D choline, glyphosate + 2,4-D amine and ammoniumglufosinate; 
and control without application, sprayed at V6 soybean
growth stage. After harvest, the seeds were submitted to first germination
count, accelerated aging, germination speed index, shoot and root length,
shoot and root dry mass and electrical conductivity tests.
Results: The management of Enlist E3 soybeans with Enlist herbicides
(2,4-D choline + glyphosate and 2,4-D choline) as well as glyphosate +
2,4-D amine and glufosinate did not negatively impact soybean
parameters such as: vigor, germination count, accelerated aging,
germination speed, aerial part and primary root length, aerial part and
root dry mass and electrical conductivity.
Conclusions: Those herbicides can be recommended to be used on post
emergence (V6) of Enlist E3 soybean.
