For the control of Powdery Mildew and Rust in Wheat and Barley.

GENERAL INFORMATION
TERN is a fungicide from the morpholine group with systemic, translaminar, protectant and early curative properties. It is rainfast in 2 hours. TERN is best used as a protective treatment during early crop development.

RESISTANCE MANAGEMENT
Disease control may be reduced if strains of pathogens less sensitive to TERN and related morpholine products develop. To minimise this risk use strictly in accordance with the label instructions. Use a maximum of 2 applications of TERN or any other morpholine fungicide per crop per season.

MIXING
When tank mixing with other products, add wettable powders, water dispersible granules and flowables first into the partly filled spray tank. Half fill the spray tank with clean water and start agitation. Whilst filling the remainder of the spray tank add the required amount of TERN, adding any tank mix products first. Maintain agitation until spraying is complete.

APPLICATION
Use 200 litres/ha of water; higher water volumes, 250 to 300 litres/ha, may be needed in dense or advanced crops. Uniform coverage is essential for best results. Wetting agent additives are not normally required when using TERN.

COMPATIBILITY
TERN is compatible with most commonly used cereal herbicides, insecticides and fungicides. Before using any tank mixture, consult and comply with the recommendations of the partner product. Each product should be added separately to the bulk of the water in the spray tank whilst filling and agitator working. As formulations of other manufacturer’s products are beyond the control of Syngenta all mixtures should be tested prior to use. Use of mixtures is at the users risk.

STORAGE
Store in a cool dry place and protect from sunlight. Avoid temperatures below minus 5°C or above 35°C.
