HOT-UP Spray Adjuvant
Product Description
Hot-Up™ is a unique spray adjuvant that contains wetters, ammonium sulphate and mineral oil in an easy to mix and stable formulation.
Unique blend of nonionic surfactants, ammonium sulphate and
mineral oil in a stable, ready to use formulation.
For use with knockdown herbicides in non-crop situations.
Will assist in wetting and spreading of herbicides on weeds.
Reduces hard water degradation and alkaline hydrolysis of
certain herbicides.
Increases penetration of herbicides through waxy weed
cuticles.
Delays the dry down rate of spray droplets on weeds.
Enhances the performance of certain combinations of
herbicides.
HOT-UP is a multi-functional adjuvant designed for use with
knockdown herbicides. It is this unique combination of
surfactants, ammonium sulphate and mineral oil in an easy to mix
and stable formulation that provides HOT-UP with its range of
exceptional properties.
Product Performance
HOT-UP combines the properties of surfactants, ammonium
sulphate and mineral oil, all of which are known to provide
adjuvancy to knockdown herbicides under certain conditions.
1. The surfactants lower the surface tension of the spray droplet.
This will increase (A) retention of the droplet on the weed surface
at initial impact and
(B) coverage of the herbicide on the weed
surface due to enhanced wetting and spreading.
HOT-UP
enhances herbicide performance on hard to wet weed surfaces.
2. Ammonium sulphate protects certain herbicides
eg. glyphosate from being deactivated in hard water. For optimum
results it is necessary to add HOT-UP to the water prior to adding
the herbicide. Ammonium sulphate can also assist in the uptake
of herbicides into the weed and their translocation to the active
site. HOT-UP enhances herbicide performance in hard water.
3. The mineral oil will act as an anti-evaporant slowing the dry
down rate of the spray droplet so that the herbicide has a longer
time to enter the weed. It will also assist in the modification of
the weed’s protective cuticle thereby increasing herbicide
penetration. HOT-UP can enhance herbicide performance during
hot weather.
4. HOT-UP will buffer the pH of spray water to approximately 7.0
which is neutral. This will help to reduce degradation of the
herbicide due to alkaline hydrolysis which can occur when the
water’s pH is greater than pH 7.0.
Product Usage
HOT-UP is designed for use with non-selective herbicides in noncrop situations only.
HOT-UP use rate : 0.25 - 1.0 L / 100 L of
Spray Volume.
The high end of the HOT-UP usage rate is recommended when ;
mixing in hard water (>340 ppm CaCO3 )
conditions are hot or dry
treating difficult to control weeds
When using a herbicide that can be degraded by hard water (eg.
glyphosate), it is advisable when using hard water to add HOT-UP to
the spray tank before the herbicide, to reduce herbicide loss.
Evaluation and Testing
Trials and compatibility studies have shown that HOT-UP is an
excellent adjuvant for use with knockdown herbicides
particularly when hard water is used and/or the air temperature is
high.
HOT-UP is suitable for mixing with a wide range of
knockdown herbicides and can enhance the performance of
certain combinations of herbicides.
