HEADLAND ENTAIL
240g/l nicosulfuron
Grass and Broad leaved weed Control in Maize – Spring 2015
ENTAIL, containing 240 g/l nicosulfuron in an oil dispersion formulation is a selective herbicide
from Headland Agrochemicals for the control of a range of grass and broad-leaved weeds in Grain
and Forage Maize.
The maximum label rate is 170 ml/ha, applied from two to eight ‘true leaf’ stage (GS 18) of the
maize, with one application per crop.
ENTAIL requires the addition of an esterified rapeseed oil adjuvant at a concentration of 0.5% of
total spray volume, for which Headland recommends the use of HEADLAND FORTUNE (ADJ
0703).
Efficacy: Replicated trials work carried out to EPPO standards in the UK on maize crops
demonstrated its equivalence to the industry standard nicosulfuron product with excellent levels of
grass weed control and equivalent broad-leaved weed control.

Crop Safety: Tank mix trials have been carried across five varieties, using Entail at 125 ml/ha
(30g a.i) in mixture with Callisto, Calaris, Blazer M (pendimethalin) or Butryflow. At the time these
trials were undertaken maize crops were under stress, caused by a mixture of waterlogging
following prolonged rainfall and cold weather conditions. In all cases, except mixtures with
bromoxynil and adjuvant, any crop effects were transient, and were outgrown by the crop.

Entail contains nicosulfuron
Callisto contains mesotrione
Calaris contains mesotrione + terbuthylazine
Butryflow contains bromoxynil
During the spring 2013 season when the weather was warm, relatively dry and maize crops grew
well and were not under stress, no crop effects were experienced where Fortune was added to the
mix regardless of the partner product(s).
Our view on a mixture with Entail and bromoxynil is that it is OK, provided the crop is not under
stress from any climatic factor, nor from deficiency of either macro- or micro nutrient. Additional
adjuvant should be avoided with this mixture.
Headland is happy to endorse a range of micronutrient products in mixture with Entail. Although
the label itself appears to prohibit such tank mixes, further work has been undertaken to prove
compatibility with a range of micronutrient products.
Where more extensive tank mixes are employed, such as Entail + a partner herbicide + a complex
micronutrient product, it may be an option to omit the adjuvant. This strategy should be considered
where the maize crop is under stress, and the weather conditions are cooler and more variable
than ideal.
Typical herbicide tank mixes include:
Entail, 125 ml/ha + Callisto, 0.75 l/ha
Entail, 125 ml/ha + Calaris, 0.75 l/ha
Entail, 125 ml/ha + Butryflow, 1.0 l/ha
Entail, 125 ml/ha + PDM 330EC, 4.5 l/ha
Compatibility: A number of physical compatibility tests have been carried out, all of which are
positive. A list of these compatibilities can be found on the Headland Agrochemicals Ltd website,
