oedema. If ingested, perform gastric lavage and administer activated charcoal.
GENERAL INSTRUCTIONS
This product is not systemic but moves quickly into leaves following application. It is important that thorough
coverage is achieved so that the maximum amount of product can be deposited on the leaf surface for
uptake and subsequent ingestion by sucking Mites.
RESISTANCE WARNING
It is known that early development of Mite resistance may occur of one particular miticide and miticides from
one particular chemical group are continually used. For this reason, it is recommended that this product be
applied no more than recommended in this label per season. A second and more applications are only
recommended where Mite pressure is very high. It is also recommended to alternate this product with
miticides from a different chemical group.
BIOMECTIN®18 EC is a group code 6 insecticide. Any insect population may contain individuals naturally
resistant to BIOMECTIN®18 EC and other group code 6 insecticides. The resistant individuals can
eventually dominate the insect population if these insecticides are used repeatedly. These resistant insects
may not be controlled by BIOMECTIN®18 EC or any other group code 6 insecticide.
To delay insecticide resistance:
•avoid exclusive repeated use of insecticides from the same insecticide group code. Alternate or
tank-mix with products from different insecticide group codes,
•integrate other control methods (chemical, cultural, biological) into insect control programmes.
For specific information on resistance management contact the registration holder of this product.
Since occurrence of resistant individuals is difficult to detect prior to use, Villa Crop Protection (Pty) Ltd
accepts no liability for any losses that may result from the failure of this product to control resistant insects.
Mode of Action:
Biomectin 18 EC is an emulsified concentrate which allosterically activates glutamate-gated chloride
channels (GluCls) resulting in increased chloride ion flow and causing paralysis. It is an effective Insecticide,
acaricide and nematicide active by both contact and ingestion, limited systemicity, but exhibits translaminar
mobility.
USE RESTRICTION
BIOMECTIN®18 EC is registered for the control of Leafminer in wheat and barley, grown under
irrigation in the Douglas and Prieska areas for use only by members of the Griqualand West

not use it in tank mixtures with products other than those mentioned on this label.
•When spraying BIOMECTIN®18 EC in citrus, apples and pears alight mineral oil should be added at
recommended label rates.
•Do not apply Captab (captan) or sulphur sprays within two (2) weeks before or after applying
BIOMECTIN®18 EC plus oil as fruit and/or leaf spotting may result.
•In cotton, molasses may be used with BIOMECTIN®18 EC for aerial application.
•Tank mixtures containing synthetic pyrethroids should contain the lowest pyrethroid dose rate for weekly
protection.
•Do not add adjuvants or surfactants not listed in this label, to spray mixtures of BIOMECTIN®18 EC.
•Consult the supplier for the latest information on the compatibility of BIOMECTIN®18 EC.
Mixing instructions:
•Half fill the spray tank with clean water.
•Mix the required quantity of BIOMECTIN®18 EC with at least 10 litres water and add to the tank whilst
agitating. If any other product (e.g., mineral oil) will be used in a tank mixture with BIOMECTIN®18 EC,
the required quantity of that product must be pre-mixed in a similar way.
•Pre-mix the BIOMECTIN®18 EC and oil together before adding to the mixing tank.
•Add the required mixture to the water while stirring.
•Fill the spray tank with water to the required level while maintaining agitation, to ensure thorough mixing.
Water quality in respect of pH values and hardness will not affect the efficacy of BIOMECTIN®18 EC.
•Prepared spray mixtures must be used immediately and not left in the spray tank for any length of time,
e.g., overnight.
Number of sprays per crop:
Do not apply more than:
2 sprays per season in vines, or
3 sprays per season in citrus, or
3 sprays per season in cotton, or
4 sprays per season in apples, pears and strawberries and
5 sprays per season in tomatoes and potatoes.
Application techniques:
All spray applications of BIOMECTIN®18 EC must be performed with appropriate equipment that is properly
calibrated and in good working order. Ensure a good even application of spray mixture on the target crop,
for maximum efficacy.
Ground application:
Apply in enough water, to ensure even coverage of the target area. The volume of water needed will depend
on the growth stage of the plants and the type of equipment used.
"Tramline" application:
For use in dryland cotton grown in tramlines. Use 50 to 100 litres spray mixture per hectare depending on
the size of the cotton plants. Use at least 5 nozzles equipped with hollow cone tips for each set of tramlines.
Two nozzles must spray directly on top of each of the two rows, one between the rows and the two outside
nozzles, mounted on drop arms, must spray upwards at an angle of 45 degrees.
Aerial application:
Aerial application of BIOMECTIN®18 EC may only be done by a registered aerial application operator using
a correctly calibrated, registered aircraft according to the instructions of SANS Code 10118 (Aerial
Application of Agricultural Pesticides). Ensure that the spray mixture is distributed evenly over the target
area and that the loss of spray material during application is restricted to a minimum. It is therefore essential
that the following criteria be met:

5: 24/1/2023 – Jan2023
BIOMECTIN®18 EC PAGE 6OF 10
•Volume: A spray mixture volume of 30 litres per hectare is recommended. As this product has not been
evaluated at a reduced volume rate, the registration holder cannot guarantee efficacy, or be held
responsible for any adverse effects if this product is applied aerially at a lower volume rate than
recommended above.
•Droplet coverage: 25 to 35 droplets per cm² must be recovered at the target area.
•Droplet size: A droplet spectrum with a VMD of 280 to 300 micron is recommended. Limit the
production of fine droplets less than 150 micron (high drift and evaporation potential) to a minimum.
•Flying height: Maintain the height of the spray boom at 3 to 4 metres above the target. Do not spray
when aircraft dives, is in a climb or when banking.
•Use suitable atomising equipment that will produce the desired droplet size and coverage, but which will
ensure the minimum loss of product. The spraying system must produce a droplet spectrum with the
lowest possible Relative Span.
•Position all the atomisers within the inner 60 to 75 % of the wingspan to prevent droplets from entering
the wingtip vortices.
•The difference in temperature between the wet and dry bulb thermometers, of a whirling hygrometer,
should not exceed 8 °C.
•Stop spraying if the wind speed exceeds 15 km per hour.
•Stop spraying under turbulent, unstable and dry conditions during the heat of the day.
•Spraying under temperature inversion conditions (spraying in or above the inversion layer) and/or high
humidity conditions (relative humidity 80 % and above) may lead to the following:
a) reduced efficacy due to suspension and evaporation of small droplets in the air (inadequate
coverage),
b) damage to other sensitive crops and/or non-target areas through drifting of the suspended spray
cloud away from the target field.
•Ensure that the aerial spray operator knows exactly which fields to spray.
Obtain an assurance from the aerial spray operator that the above requirements will be met, and that
relevant data will be compiled in a logbook and kept for future reference.

Spider mite scouting technique for cotton:
Use this technique to establish the degree of infestation. Start inspections three weeks after germination
and continue weekly inspections until first boll split at about 20 weeks. Select 48 plants at random for
inspection in areas covering up to a maximum of 15 hectares. Examine one leaf from the middle and two
from near the top of each of the selected plants. Count the total number of adult female Mites present and
allocate the following numerical scores accordingly:
Zero adult females = 0
1 to 10 adult females = 1
11 to 30 adult females = 2
31 or more adult females = 3
Calculate the population index by dividing the total numerical value by the number of plants sampled (48).
The level of infestation will have a value between 0 and 3. It is essential to keep the index below the
economic threshold level of 0.8 for the first 12 weeks and thereafter below an increasing economic threshold
level that reaches a value of 2.0 at 20 weeks, by spraying BIOMECTIN®18 EC as recommended.

NOTE
•BIOMECTIN®18 EC is suitable for use in Integrated Pest Management Programmes (IPM). When
applied at the recommended rates it will not control all the Spider mites in a crop. Survivors will supply a
food source for the predatory Mites thus encouraging a build-up in their numbers.
•BIOMECTIN®18 EC will not adversely affect lint quality in cotton.
•BIOMECTIN®18 EC is quickly taken up by the plant. It will not easily be washed off by rain and/or
irrigation if the spray mixture has had sufficient time to dry properly.
•Heavy spray applications can reduce the efficacy of BIOMECTIN®18 EC by causing run-off.
•BIOMECTIN®18 EC does not have a fast knockdown effect on mites or Leafminers and the time taken
to reach maximum control is temperature dependent. This can vary from 3 to 5 days. During this time
crop damage is minimal due to the mobility of the pests being curtailed by BIOMECTIN®18 EC.
•Spray residues of BIOMECTIN®18 EC have a negligible effect on predatory Mites and other beneficial
arthropods.
Consult the Villa 51, Charge and Masterlock®labels for WARNINGS, PRECAUTIONS and DIRECTIONS
FOR USE.
