Lightning� Herbicide
and the Clearfield�
Production System
Compliments
of Agronomy Services Department
History
Lightning� herbicide was developed by American Cyanamid in 1990 to offer
corn producers herbicide options to control a variety of tough grasses and weeds. In 1997
the EPA registered Lightning�, and in 1999 it became one of the newest members
of the Clearfield� production system.
How does Lightning�
kill weeds?
Lightning� control a broad spectrum of broadleaf and grass weed species by
contact and residual soil activity through weed foliage and roots. After application,
Lightning� is taken up by the foliage and translocated throughout the plant.
Keys to
application success
-
Apply only to
Clearfield� corn hybrids.
-
Make sure planter is
completely empty before filling with Clearfield� corn.
-
If you have heavy
grass pressure, use a companion herbicide.
-
Cultivation 7 –
10 days after application will enhance residual weed control.
-
If air temperature is
50 degrees or less for 10 or more hours, delay application for 48 hours.
-
There needs to be 1
hour from application to the first rainfall for proper absorption.
-
Thoroughly clean out
sprayer when complete.
Rate
and timing of application
Apply Lightning� at a rate of 1.28 oz. per acre.
Optimum control of
weeds has been obtained with early postemergence application of Lightning� to
weeds that have one to four leaves (2 to 4 inches tall) and before Clearfield�
hybrid are 18 inches tall. Apply postemergence to Clearfield� hybrids when
crop and weeds are actively growing. Time the application to maximize coverage on emerging
weeds.

Crop
safety with Lightning� herbicide:
-
Rotational crop
intervals for soybeans are 9.5 months.
-
No triazines, which
reduces triazine load on environment.
-
Excellent crop safety
with Clearfield� hybrids with no concern about crop injury.
-
No soil
insecticide/herbicide interactions, allowing greater flexibility.
-
Mycogen Seeds offers
many high yielding Clearfield� hybrid choices to maximize yields with optimum
weed control.
