Description
Mepiquat Formulations
Technical Field
The invention relates to novel mepiquat formulations. In particular, the invention is
concerned with highly loaded mepiquat formulations, mepiquat being present as the
chloride.
Background Art
Mepiquat chloride (1,1-dimethylpiperidin-1-ium chloride) consists of equimolar amounts of the mepiquat cation and the chloride anion. It is a well-known plant growth regulator,
which inhibits biosynthesis of gibberellic acid (GA) in plant tissue. Inhibition of GA production reduces vegetative growth and increases yield. Mepiquat chloride can be
used on a range of crops but is especially useful commercially to reduce vegetative growth of cotton and to inhibit sprouting in bulbs, such as garlic, leek and onions.
In cotton, mepiquat chloride can increase output of cotton by reducing height and vegetative growth, as well as boll shedding. Vegetative growth is regarded as a pattern
of extension of cotton plant height through stem and branch growth. Mepiquat chloride stunts vegetative growth in cotton, resulting in an increase in cotton boll production.
Mepiquat can be combined with ethephon to reduce internode length in cereals such as
wheat, thereby preventing lodging (which is the permanent displacement of the cereal stems from their upright position).
Mepiquat chloride has high solubility in water: over 50% w/w at 20°C. It is available at a high purity of 980 g/kg or more. However, commercial formulations typically contain a
low concentration of mepiquat chloride per litre. Where mepiquat chloride is the sole active ingredient, commercial formulations typically contain 51 g/L of mepiquat chloride
(38 g/L of mepiquat acid) Where mepiquat chloride is combined with ethephon, the
concentration of mepiquat chloride maybe as high as 305 g/L (232 g/L of mepiquat acid).
High concentration formulations are generally desirable: a highly loaded formulation can
deliver the required quantity of active ingredient to a user in a smaller volume. Higher
I concentration formulations also reduce the quantity of formulated product required to be produced by formulators. For both formulators and users there is a saving in packaging, freight costs, storage volume and energy costs and a reduction in waste.
Mepiquat acid use rates range from 9.5 to 76 g/ha. This means that formulated product use rates for existing available solo formulations typically range from 250 mL/ha to 2
L/ha. The bulk of the current formulations - more than 90% - comprises water. It is
clearly inefficient to produce, store and transport to growers such a bulky product.
Therefore, it would be beneficial to provide formulations of mepiquat chloride which are
more highly loaded than those currently available.
It has been discovered that it is possible to provide mepiquat chloride formulations that
are more highly loaded, yet stable.
Summary of the Invention
Accordingly, the invention provides a soluble concentrate mepiquat formulation having a concentration of mepiquat, present as mepiquat chloride, of about 380 g ae/L,
wherein the mepiquat chloride is the only active ingredient in the formulation and
wherein the formulation is free from ethylene oxide/propylene oxide block copolymer.
While the formulation of the invention has only mepiquat chloride as the sole active
ingredient, the formulation may include any other desirable or convenient adjuvant type ingredient. Preferably, the formulation includes a suitable colorant, an anti-foaming
agent and water.
A colorant is used to warn users that the formulation contains mepiquat chloride. An
example of a suitable colorant is New Coccine-Dye Content 75% (trisodium (8Z)-7-oxo-8
[(4-sulfonatonaphthalen-1-yl)hydrazinylidene]naphthalene-1.3-disuifonate), available
from Sigma-Aldrich in Saint Louis, Missouri, USA.
Preferred as anti-foaming agent is Gensil 2030 TM, a polydimethylsiloxane aqueous emulsion available from Solvay Chemicals Pty Ltd in Bundoora, Victoria, Australia. Other
anti-foaming agents may also be suitable.
Testing has shown that the highly loaded formulations of the invention are stable,
including in cold conditions.
Trial results on cotton crops have shown that formulations of the invention are as
effective as and a bioequivalent of a prior art mepiquat formulation, namely RewardTMin relation to regulation of fruiting and vegetative growth. RewardTM has as its only active
ingredient mepiquat, present as the chloride salt, at a concentration of 38 g/L.
The benefits of the formulation of the invention include a more suitable concentration of active ingredient, given that, in the main crop use in Australia, namely cotton,
application rates range from 250 mL/ha to 2 L/ha of mepiquat acid. Current formulations, with only 38 g/L of mepiquat acid, are more than 90% water. This is an
inefficient and bulky product for the manufacturer to produce, store and transport and for growers to apply.
In order that the invention in its various aspects may be more readily understood and put into practice, one or more preferred embodiments thereof will now be described.
Detailed Description of Preferred Embodiment
Example 1: Preparation of Soluble Concentrate Formulation (SL) containing 380 g/L of

Example 2:
Field Trial - Norwin, Queensland
A field trial was conducted near Norwin, Queensland, Australia to evaluate post
emergence applications of mepiquat applied to conventional cotton cv. at mid-bloom to early boll set.
The cotton crop trialled was American upland cotton (Gossypium hirsutum).
The purpose of the trial was to assess the bio-equivalence of the formulation of Example 1 with the commercially registered formulation 'Reward'.
The formulation of Example 1 was identified as AD-AU-1815. In the trial, a comparison was made between an untreated plot group and 28.5, 76 and 152 ga/ha of each of
Reward (38 g/L mepiquat) and AD-AU-1815 (380 g/L mepiquat).
Treatments were applied post-emergence, using a hand-held boom fitted with 6
TT11015 nozzles, calibrated for an output of 100 L/ha at a ground speed of 5.4 kph and an operating pressure of 250 kPa to irrigated cotton cv. 75RRF at mid-flowering to early
boll development.
The treatments are summarised in Table 2 below:
Table 2
Trt Treatment Active Rate (gac/ha) Dosage Rate (mL No. Ingredient /ha) 1 Untreated --

Prior to planting height, length of 6 terminal nodes and nodes above white flower
(NAWF) were measured on 10 marked plants per plot. These parameters were then re measured on the same 10 plants 21 days after application (21 DAA).
Total number of bolls and numbers of open and closed bolls and numbers of immature bolls were recorded on the tagged 10 plants at 54 days after application (54 DAA). A
calculation of percentage of "harvestable" bolls was derived from the counts of
harvestable bolls and total bolls.
At 90 days after application (90 DAA), the weights of seed cotton from 100 open bolls
per plot were recorded to derive a value of boll weight. Samples were ginned by CSD and submitted to Australian Classing Services for quality analysis.
Values for gin turnout, staple length, fibre length, fibre micron diameter, fibre uniformity, fibre strength and short fibre index were measured in addition to fibre
classing values.
The results are shown in Table 3 (Plant height) and Table 4 (Nodes above white flower), below.

Reward.
Example 3:
Field Trial - Dalby, Queensland
A field trial was conducted near Dalby in the Western Down region of Queensland, Australia. The purpose of the trial was to evaluate bioequivalence of the formulation of
the Example 1 (AD-AU-1815) and the commercially registered formulation 'Reward', when used for growth regulation in cotton (Sicot 75BRF).
The treatments were as set out in Table 2, above.
Treatments were applied using a gas operating boom sprayer incorporating four Teejet
TT110015 flat fan nozzles. At an application speed of 1.5 metres per second and a pressure of 200 kPa, treatments were applied in a total volume of 118 L/ha and a
medium quality. The treatments were applied once at BBCH 62.
Detailed assessments were conducted pre-spray, at 4 and 7 weeks after application
(WAA) and at harvest. These included counts of number of nodes above white flower
(NAWF) and crop height
The results are shown in Table 5 (Nodes above white flower), Table 6 (Plant height) and
Table 7 (Mean crop height) below.

As shown in Table 5 (Mean Number of Nodes Above White Flower), there were significantly fewer nodes (NAWF) in the cotton treated with AD-AU-1815 at 76 g ai/ha, than in the untreated cotton. A rate effect was seen with REWARD with fewer nodes at the 152 g ai/ha rate than at the 28.5 g ai/ha rate. There were fewer nodes (NAWF) on the cotton plants treated with AD-AU-1815 at 28.5 and 76 g ai/ha than with the equivalent rates of REWARD. The application of AD-AU-1815 had a greater effect on growth than REWARD.

AD-AU-1815 provided similar or better overall reduction in vegetative growth was as per the results in table 6. Assessments at four and seven weeks after application indicated
than all three rates of AD-AU-1815 reduced the amount of crop height after application.
It will be appreciated from the data in Tables 2 to 6 that the efficacy of the formulation
of the invention is at least comparable to that of the prior art formulation REWARD. In one field trial, the formulation of the invention was more effective than REWARD.
The formulation of the invention, being more concentrated, is more efficient. An
increase in loading from 38 g ae/L to 380 g ae/L represents a 90% reduction in the volume of material to be formulated, transported, stored and applied by the end user.
