GROUP M4 FUNGICIDE

For the control of certain diseases in a range of fruit crops, almonds, pistachios, turf and ornamentals as shown under Directions for Use.

DIRECTIONS FOR USE
TREE AND VINE CROPS
RESTRAINT: DO NOT apply this product by aircraft.

RATE: In the following table, all rates are given for dilute spraying. For concentrate spraying, refer to the Mixing/Application section.
CRITICAL COMMENTS: For all uses in this table apply by dilute or concentrate spraying equipment. Apply the same total amount of product to the target crop whether applying this product by dilute or concentrate spraying methods.
DO NOT use at concentrate rates greater than 250 g/100 L water.

APPLES
Disease: Black Spot (Venturia inaequalis)
State: All States
Rate/100L:
Dilute spraying 125 g/100L
Concentrate spraying Refer to the Mixing / Application section
WHP: 7 days
Critical comments: Apply from pink stage onwards following a copper spray at green tip, then at 7 day intervals until petal fall. After petal fall apply as a cover spray at 10-14 day intervals. The risk of russet may be increased in some varieties. Where this is of concern use alternative materials between full bloom and second cover. Apply to point of run-off. Apply no more than five applications per season.

Dilute spraying 200 g/100L
Concentrate spraying Refer to the Mixing / Application section
WHP: 28 days
Critical comments: For almonds, apply at either pink bud, full bloom, petal fall or at 2-3 and 4-6 weeks post petal fall using the shorter intervals under heavy pressure. For pistachios, apply from bud swell through to full bloom stage in orchards with a history of disease pressure. As part of an overall spray program, further applications may be applied during spring and summer where favourable disease conditions exist. Apply when climatic conditions favour disease development. Apply in a protective program alone or with other fungicides approved for the specified diseases. Apply no more than five applications per
season.

EXPORT TRADE ADVICE:

GENERAL INSTRUCTIONS
FUNGICIDE RESISTANCE WARNING
For fungicide resistance management Adama CAPTAN 800 WG Fungicide is a Group M4 fungicide. Some naturally occurring individual fungi resistant to Captan 800 WG and other Group M4 fungicides may exist through normal genetic variability in any fungal population. The resistant individuals can eventually dominate the fungal population if these fungicides are used repeatedly. These resistant fungi will not be controlled by Captan 800 WG or other Group M4 fungicides, thus resulting in a reduction in efficacy and possible yield loss.
Since the occurrence of resistant fungi is difficult to detect prior to use, Adama Australia Pty. Ltd. accepts no liability for any losses that may result from the failure of Captan 800 WG to control resistant fungi.

MIXING
Captan 800 WG mixes readily with water and should not be pre-mixed. Slowly add the required amount of product to the water under agitation in the spray vat. Maintain agitation throughout spraying. After a stoppage, thoroughly re-mix before recommencing spraying.

COMPATIBILITY AND CROP SAFETY
Mixtures of Captan 800 WG with commonly used wettable powders and suspension concentrate insecticides and fungicides should not cause any problems. Apart from the products listed below mixtures with emulsifiable concentrates are not recommended. If tank mixes are to be used observe all directions, precautions and limitations on all products to be used. Caution should also be exercised when spraying any mixtures on varieties of fruit trees or vines where there has been no previous experience of mixtures with Captan 800 WG.
Captan 800 WG is compatible with any one of the following products: Anvil, Bayfidan, Topaz, Penncap-M, Gusathion 200 SC with or without calcium nitrate, Bugmaster Flowable, Confidor, Hymal, Insegar, Kumulus, Lebaycid, Lorsban, Mavrik Aquaflow, Omite 300WG (apples only), Pirimor WG, Pyranica, Saboteur, Sanmite, Systhane.
A mixture of Captan 800 WG with more than one of these products or with any other product may be ineffective or may cause serious damage. The use of such a mixture is not recommended without prior advice, and would therefore be entirely at the user’s risk. If other mixtures or 3 way mixtures of any of these products are being considered consult your Adama dealer or representative for advice.
Mixtures of Captan 800 WG with Lorsban 500EC or Nimrod may leave an oily residue on the inside of spray vats which may be difficult to remove.
Captan 800 WG should not be combined with Bordeaux mixture, spray lime, lime sulphur or oils. DO NOT apply Captan 800 WG in combination with or within 14 days before or after winter or summer oil sprays. Combinations of Captan 800 WG and sulphur should not be used on crops sensitive to sulphur.
Captan 800 WG mixed with Folidol M500 may be phytotoxic to many varieties of apples and pears. If it is necessary to use both Captan 800 WG and Folidol M500 in a spray program, sprays of these products must be at least 7 days apart.
On pears tank mixtures of Captan 800 WG plus Omite 300WG and Captan 800 WG and Gusathion (without calcium nitrate) plus Omite 300WG have been found to be phytotoxic.
DO NOT tank mix these products, for use on pears.
Caution should be taken when applying chemical mixtures to all crops. Varieties within crop groups may react differently therefore a small area should be tested prior to application to crop.

APPLICATION
Ground application – these rates are for high volume spraying to point of run-off. DO NOT apply by aircraft.
Dilute Spraying: Use a sprayer designed to apply high volumes of water up to the point of run-off and matched to the crop being sprayed. Set up and operate the sprayer to achieve even coverage throughout the crop canopy. Apply sufficient water to cover the crop to the point of run-off. Avoid excessive run-off. The required water volume may be determined by applying different test volumes, using different settings on the sprayer, from industry guidelines or expert advice. Add the amount of product specified in the Directions for Use table for each 100 L of water. Spray to the point of run-off. The required dilute spray volume will change and the sprayer set up and operation may also need to be changed, as the crop grows.
Concentrate Spraying: Use a sprayer designed and set up for concentrate spraying (that is a sprayer which applies water volumes less than those required to reach the point of run-off) and matched to the crop being sprayed. Set up and operate the sprayer to achieve even coverage throughout the crop canopy using your chosen water volume. Determine an appropriate dilute spray volume (see Dilute Spraying above) for the crop canopy. This is needed to calculate the concentrate mixing rate. The mixing rate for concentrate spraying can then be calculated in the following way.
Example only
1. Dilute spray volume as determined above: For example 1000 L/ha
2. Your chosen concentrate spray volume: For example 500 L/ha
3. The concentration factor in this example is :
2 X (i.e. 1000 L ÷ 500 L = 2)
4. If the dilute label rate is 125 g/100 L, then the concentrate rate becomes 2 x 125, that is 250 g/100 L of concentrate spray.
The chosen spray volume, amount of product per 100 L of water, and the sprayer set up and operation may need to be changed as the crop grows.
DO NOT use at a concentration rate higher than that specified in the Critical Comments as crop safety has not been assessed.
For further information on concentrate spraying, users are advised to consult relevant industry guidelines, undertake appropriate competency training and follow industry Best Practices.

PRECAUTION
Re-Entry Periods: DO NOT allow entry into treated areas until the spray has dried. When prior entry is necessary wear cotton overalls buttoned to the neck and wrist (or equivalent clothing) and chemical resistant gloves. Clothing must be laundered after each day’s use.
