GENERAL INSTRUCTIONS

MIXING PROCEDURE:
Half fill the spray tank with water. Engage pump agitation. Add the required amount of MERPAN to the half filled spray tank then complete tank filling, continuing to agitate the mixture during filling and use. When tank mixing MERPAN with another product, ensure products are added in the following order with tank agitation running.
1. First add MERPAN to the half-filled tank.
2. Add any fungicides and insecticides to a ¾ full tank with agitation running (add WG’s, WP’s followed by SC’s and EW’s).
3. If adding foliar fertilisers such as Calcium Chloride (CaCl2), or Calcium Nitrate (Ca(NO3)2) or a surfactant, these must always be added last. Refer to the specific product labels for any preparation required before adding to the spray tank.
4. Do not leave mixed spray standing overnight.

APPLICATION
The rates suggested are for high volume spraying to run-off. For concentrate spraying adjust dilution rate accordingly. Calibrate equipment to give the desired application rate and full coverage of foliage. Fine droplets are more effective than coarse droplets. Ensure undersides of leaves are treated. Keep agitated during use, and agitate thoroughly after a stoppage before recommencing spraying.

COMPATIBILITY
Merpan Fungicide is compatible with most commonly used pesticides. It should not be combined with Bordeaux mixture, lime sulphur, oils or dicofol. Its use with emulsifiable concentrates is not recommended. If used in combination with sulphur on Kidds Orange, Delicious and some sulphur-shy varieties, some leaf spotting and drop may occur.
