DESCRIPTION
The ULVA+ is a simple robust hand-held spinning disc Controlled Droplet
Application (CDA) sprayer powered by torch (D-cell/R20) batteries, with one set of
good quality batteries giving up to twenty hours spraying time. It is designed
primarily for the foliar application of insecticides and fungicides –both water-based
mixtures (e.g. ECs, WPs) at 10 to 20 litres/hectare total spray volume and involatile
Ultra-Low Volume (ULV) formulations at 1 to 3 litres/hectare. An electric motor
spins the atomiser disc to produce uniform spray droplet size ranges (the actual size
of droplets produced depends on the atomiser disc speed which is determined by the
number of batteries fitted). Liquid is fed by gravity through colour coded feed
nozzles. The ULVA+ can apply insecticides and fungicides to various row crops e.g.
cotton, groundnuts, rice, vegetables, etc., (and it can also be used for the control of
migrant pests with ULV formulations e.g. locusts, grasshoppers and armyworm). The
sprayer produces relatively small spray droplets which are distributed and deposited
by wind and gravity, allowing several rows/metres to be treated during each spray
pass. The sprayer must therefore always be held downwind of the operator.

Specially designed Micropak backpacks can be supplied for use with the ULVA+,
with a refilling system to refill the one litre spray bottle fitted to the spray head. Only
use ULV formulations with a backpack if appropriate chemically resistant tubing is
available (e.g. Micron Micropaks fitted with EVA tubing).
SAFETY
Using agrochemicals is a hazardous process. Operators should comply with all
relevant legislation and/or regulations governing the use of agrochemicals and should
use appropriate personal protective equipment (see ‘OPERATOR PROTECTION’).
The ULVA+ can be used with most traditional water-based insecticide and fungicide
products, as well as specific ULV formulations (only available in some countries)
which can reduce risks in mixing and filling.
Always read the product label carefully to discover:-
approved applications
maximum dose rates
maximum number of treatments
operator protection required
necessary environmental protection measures
N.B. ‘Dose rate’ refers to the amount of chemical product applied per hectare.
Never eat, drink, or smoke when working with agrochemicals. After using
agrochemicals or handling equipment wash your hands thoroughly. Keep people
(especially children) and animals out of areas being sprayed.
Always store agrochemicals safely to protect people and animals, and to safeguard
the environment (take special care to avoid water pollution). See ‘SPRAYING’
sections for guidelines on safe use of the ULVA+ in operation.
OPERATOR PROTECTION
Always wear the protective clothing items listed on the product label for mixing and
filling. The minimum protective clothing required for spraying with the ULVA+ is:
rubber gloves and boots
Face shield, eye protection and hat
long sleeved shirt and trousers

PREPARING FOR SPRAYING
The sprayer is delivered in a collapsed form pre-set for use with a particular number
of batteries N.B. five batteries are recommended for use with water-based products,
six to eight for ULV formulations. To assemble ready for spraying:
1) Remove the atomiser protective cover and check by hand that the atomiser disc
spins freely. Extend the sprayer and screw the one litre bottle onto the spray
head. Do not overtighten. Make sure the red cap or refilling point is in line with
the extension tube. Instructions on assembling Micron Micropak backpacks are
contained inside the tank. N.B. the feed tube from the Micropak must be securely
connected to the flow valve which should be fitted into the valve retaining clamp
on the battery case and the hose connections secured with the clips supplied. The
tubing on the sprayer should be clipped into the large hole on the battery case end
cap and attached to the flow valve.
2) Remove the switch end piece as
shown on the label.
3) Insert the required number of
batteries (D-cell/R20) negative, i.e.
flat, end first.
N.B. Battery condition should always be checked before use, either in a torch or
using a torch lightbulb and electric wire –see ‘TROUBLESHOOTING’. Before
spraying for the first time with the ULVA+, sprayer operation should be checked
using only water (see ‘BEFORE SPRAYING’).

Always wear gloves when handling
agrochemicals and equipment.
Always use the correct equipment
when mixing and measuring.
MIXING, FILLING AND CALIBRATION
Mixing and filling is generally the most hazardous process in the spraying operation.
Always follow the label instructions. Always use a filter (fitted in the Micron Mi-
cropak backpacks) and use a funnel if directly filling the spray bottle. Only mix
enough spray for the area to be treated if using water-based mixtures to avoid the
need for disposal of unused spray mix.
Always wash off any skin
contamination
Always clean all equipment after
use.
ULV FORMULATIONS
ULV formulations are pre-mixed, i.e. ready to spray, and should have full
instructions for use on the label. These products can be poured directly into the spray
bottle using a funnel, if using the one litre twin neck bottle, or directly into the
backpack.

WATER-BASED PRODUCTS
Traditional water-based insecticides and fungicides are usually applied with the
ULVA+ at 10 to 20 litres total spray volume per hectare. Most insecticides can be
used at 10 litres/hectare but fungicides may require around 20 litres/hectare. For
example, if the label recommends applying a minimum of 1 litre of insecticide
product made up to 100 litres of water per hectare with a knapsack sprayer, use 1 litre
of product made up to 10 litres for application with the ULVA+, i.e. a spray mix
concentration of 10%.
Do not use product concentrations greater than the maximum recommended on the
label (unless specific training or recommendations have been given) if the label:
a) specifically prohibits use of ‘Reduced Volumes’ i.e. increased
concentrations;
b) has a statutory requirement for use of personal protective equipment when
using the diluted product at high volumes (N.B. this will appear in the
statutory box on the label);
or
c) carries one of the following hazard ratings: ‘very toxic’, ‘toxic’ or ‘corrosive’
or carries the warning ‘risk of serious damage to the eyes’.
Micron do not generally recommend using spray mixes of more than ten times the
maximum concentration recommended for high volume application with knapsack
sprayers. At high concentrations some products can be phytotoxic to crops thus, if in
doubt, first spray a small test area. The safest product and lowest dose rate
appropriate for the treatment should be used at all times.
To prepare the spray mix with water-based products select the dose rate of product to
be applied per hectare and mix in a suitable container e.g. a Micron Micropak
Measure out the exact amount of
product.
Half fill the tank with clean water.
Check for leaks. Add the measured
product.
Never use leaking equipment. Take care to avoid spillage when filling or lifting the
tank.
6
Finish filling the tank with clean water. Replace the tank lid. Wipe the tank
with a dry cloth.
Mix well by gently shaking the tank. Place the tank on the operator‘s back.
Transfer the spray mix to the one litre
bottle on the spray head (by placing the
base of the bottle on the ground and
opening the flow valve).
ON
OFF
When the bottle is filled to the 1 litre
mark stop filling. The flow valve must
then be turned off.

CALIBRATION
ULV FORMULATIONS
The table below indicates the relationship between spray volume, flow rate and
walking speed for the ULVA+ as per the following formula:
Flow rate (ml/min) = 6 x spray pass interval (m) x total spray volume (l/ha) x walking speed (m/s)
Spray volume
(l/ha)
Spray pass
Interval (m)

0.8 Crop pests 5 Yellow 25 1.0
1.0 and diseases 5 Orange 34 1.1
1.0 3 Red 60 1.1
1.0 Migrant pests 5 Orange 34 1.1
1.0 10 Red 60 1.0
* Note: Assumes a standard ULV formulation viscosity of 7mm2/sec. The flow rate will differ
with liquid viscosity and for more viscous formulations it may be necessary to use a larger feed
nozzle.
For ULV applications spray passes of 3 to 6 meters can generally be used in crop
situations (5 to 10 meters for control of migrant pests on rangeland). Spray pass
intervals should be reduced as crop height increases.
Choose and fit the feed nozzle that is likely to be required. The actual flow rate
should be checked holding the ULVA+ in the spraying position with the feed nozzle
vertical. Remove the atomiser disc by unscrewing the disc fixing screw by hand and
then turn over the sprayer. Wait until the liquid flow is steady and then allow the
liquid to flow into a suitable container for one minute and measure the volume
dispensed. If the flow rate is substantially different from that required change the
feed nozzle and repeat the above procedure. If the flow rate is close to that required
adjust walking speed.

= 1.33
i.e. 1.33 m/s or 80 metres in one minute (1.33 x 60)
Mark out a distance of 80 metres and practice walking it in one minute.
WATER BASED PRODUCTS
Examples of mixing spray –for 1 hectare:
a) insecticide: 1litre
add water: +9 litres
Total volume: 10 litres
i.e. 1 part insecticide : 9 parts water
b) fungicide: 3 litres
add water: +17 litres
Total volume: 20 litres
i.e. 3 part insecticide : 17 parts water
The following table indicates the relationship between spray volume, flow rate and
walking speed for the ULVA+ as per the following formula:
Flow rate (ml/min) = 6 x spray pass interval (m) x total spray volume (l/ha) x walking speed (m/s)

* Note: Flow rates measured with water plus surfactant. Some products when mixed in water
can be more viscous and the actual flow rate through each feed nozzle may be different from
that indicated. For very viscous spray mixes it may be necessary to use a larger feed nozzle.
