Arrow 2 EC Herbicide is not recommended for use on vegetable crops being grown for seed production unless
specific use directions are provided.
Arrow 2 EC Herbicide is a selective postemergence herbicide for control of annual and perennial grasses.
Arrow 2 EC Herbicide does not control sedges or broadleaf weeds.
Repeated use of Arrow 2 EC Herbicide (or similar postemergence grass herbicide with the same mode of
action) may lead to the selection of naturally occurring biotypes that are resistant to these products in some
grass species.
If poor performance occurs and cannot be attributed to adverse weather or application conditions, a resist-
ant biotype may be present. This is most likely to occur in fields where other control strategies such as crop
rotation, mechanical removal, and other classes of herbicides are not used from year to year.
Do not allow Arrow 2 EC Herbicide to come in contact with desirable grass crops such as corn, rice, sorghum,
small grains, or turf, as these and other grass crops will be injured or killed. Minor leaf spotting may occur on
treated plants under certain environmental conditions. New foliage is not affected.
Control Symptoms
Treated grass weeds show a reduction in vigor and growth. Early chlorosis /necrosis of younger plant tissue
is followed by a progressive collapse of the remaining foliage. Symptoms will generally be observed in 7 to 14
days after application depending on grass species treated and environmental conditions.
When an adjuvant is to be used with this product, Makhteshim Agan of North America, Inc. suggests the use
of a Chemical Producers and Distributors Association certified adjuvant.
APPLICATION INFORMATION
Timing of Applications
Apply Arrow 2 EC Herbicide postemergence to actively growing grasses according to rate table recommen-
dations. Applications made to grass plants stressed by insufficient moisture or hot or cold temperatures or to
grass plants exceeding recommended growth stages may result in unsatisfactory control. Do not apply under
these conditions.
In arid regions where irrigation is used to supplement limited rainfall, Arrow 2 EC Herbicide should be applied
as soon as possible after an irrigation (within 7 days). In arid regions, a second application of Arrow 2 EC
Herbicide will generally provide more effective control of perennial grass weeds than a single application.
Make second application to actively growing grass 2 to 3 weeks after emergence of new growth.
Cultivation of treated grasses 7 days prior to or within 7 days after application of Arrow 2 EC Herbicide may
reduce weed control. DO NOT APPLY Arrow 2 EC Herbicide if rainfall is expected within one hour since con-
trol may be reduced.
