A synthetic pyrethroid insecticide for the control of caterpillars, beetles, thrips and aphids on a broad range of crops.
Active Ingredient: 25g/litre deltamethrin
Chemical Group: Synthetic pyrethroid
Formulation: Emulsifiable concentrate
General: Deltaphar 25EC is a quick acting synthetic pyrethroid insecticide which works through contact activity and ingestion. It is not systemic. Thorough plant coverage is essential.
Resistance Management: Brassicas – To minimise the development of resistance to synthetic pyrethroids apply only in the period from February to August. Use insecticides of a different mode of action during September to the end of January.
Onions – Refer to supplier or adviser for the local integrated Pest Management programme. A cluster of 3-4 sprays should be made from early January in response to crop monitoring when the threshold of thrip numbers has been exceeded. Ensure good cultural practices such as removal of self-sets.
Compatibility: Deltaphar 25EC is compatible with most commonly used fungicides and insecticides. Flocculation may occur when mixed with some wettable sulphur formulations.
Mixing: Add the required amount of Deltaphar 25EC directly into the spray tank with agitator operating. Maintain agitation during application.
