HASTEN Spray Adjuvant
HASTEN spray adjuvant is a blend of esterified vegetable oil and non-ionic surfactants that has :
Proven cost effective performance for over 10 years with a wide range of agricultural products
Excellent plant and insect penetrating and wetting properties
An internationally recognised tradename and reputation forreliability
Approval by Environmental Protection Agencies in many countries including the USA,
Renewable material – Vegetable oil – as its base raw material
A high quality formulation providing easy dispersion and stable emulsion characteristics,and
International Patents granted and pending.
HASTEN is a unique spray adjuvant that has been designed to
improve the efficacy of a wide range of agricultural products
including Herbicides (selective and non – selective), Insecticides,
Fungicides and Defoliants.
The use of adjuvants, such as HASTEN, with agricultural products has
been the subject of extensive research, and they are well accepted
by the agricultural industry based on the benefits they provide.
Some of the benefits that HASTEN provides include increased
crop yields, lower input costs and reduced impact on the
environment. HASTEN achieves these benefits for the agricultural
industry through its unique, patented formulation.
HASTEN may be viewed as the third generation of oil based spray
adjuvants due to its technology. The first generation adjuvants may
be viewed as those based on emulsified petroleum oil products
(COC). The second generation includes those products that are
based on emulsified vegetable oils.
HASTEN is different to these two types of products because the
active ingredient is a different class of oil known as esterified
vegetable oil. In combination with a proprietary blend of non-ionic
surfactants, HASTEN is also unique because the esterified oil is
based on an ethyl ester in contrast with other commercial
products that contain predominantly methyl esters.
When HASTEN is mixed with agricultural products and applied in
the field, the non-ionic surfactants help to retain and improve the
contact of the spray droplet on the plant or insect surface. The
esterified oil is an excellent penetrating agent through waxy
surfaces such as those of plants and insects thereby assisting the
performance of the agricultural product.
It is this dual action
which makes HASTEN a very effective adjuvant.
HASTEN may be used in place of non-ionic surfactants or crop oil
concentrates when permitted by agricultural product labels.
Typically, HASTEN is added to the spray tank at a concentration of
0.5-1.0% when spray volumes are between 50-100 Litres per
In situations where the agricultural practice is to use a
higher volume than 100 Litres per hectare, HASTEN is typically used
at 0.5-1.0 Litres per hectare.
Evaluation and Testing
Extensive testing and evaluation of HASTEN over the past 14 years
by universities, lifescience companies, research organizations and
independent researchers has proven that HASTEN is a very
effective adjuvant for improving the performance of agricultural
Based on independent university studies, it is well
established that esterified vegetable oil products out perform
both emulsified petroleum and vegetable oil based products
in many situations.
’S commercial success is confirmation that it can provide
important cost effective benefits to the agricultural industry.
