Serenade OPTI

Overview

Serenade® OPTI biological fungicide aids in the suppression of early blight and white mould in potatoes and powdery mildew, botrytis and bacterial diseases in many fruit and vegetable crops including bulb vegetables (Crop Group 3), leafy vegetables (Crop Group 4), cole crops (Crop Group 5), cucurbit vegetables (Crop Group 9), fruiting vegetables (Crop Group 8) and bushberries and caneberries (Crop Group 13).

Application Tips

Overview



  • Broad-spectrum, biological foliar fungicide that provides effective disease suppression
  • For disease control, Serenade OPTI should be used in a spray program that includes a conventional fungicide
  • Provides anti-fungal and anti-bacterial activity
  • Stimulates natural plant defense mechanisms
  • Has demonstrated increased plant growth effects
  • Is a new formulation, replacing the popular Serenade MAX, providing the same disease protection in a smaller, easier to use package.
  • Protects a variety of crops including potatoes, blueberries, leafy vegetables, pome fruit and many other fruit and vegetable crops
  • Unique mode of action (FRAC Group 44) makes for the best defense against the development of resistance
  • Is exempt from tolerances (no MRL or residue concerns), so you can sell your crops into even the most restrictive markets

 

Application Tips



  • Agitate thoroughly before application
  • Use 40-50 mesh screens if possible
  • Water pH should be between 4.5 and 8.5
  • Tanks should be sprayed out within 24 hours of mixing
  • Pre-harvest interval – Serenade® OPTI can be sprayed up to and including the day of harvest
  • Tank mixing – there are no registered tank mixes; however, Serenade OPTI is compatible with all most crop protection products. A jar test should be used to verify compatibility. Contact your local Bayer sales representative for more information.
  • Store below 25°C for up to 3 years; do not freeze
  • Registered for use by air
  • When using spray nozzle screens finer than 50 mesh, monitor for potential product buildup. This buildup is easily cleaned with water.

Resistance Management

Serenade OPTI has a unique mode of action and fungicide group (Group 44), which makes it very difficult for diseases to develop resistance. Serenade OPTI can help with resistance issues by preventing diseases from developing ways to combat single site synthetic products. Serenade OPTI works best when used in a program approach with other chemistries throughout the growing season to decrease the chance of resistance for all products on that particular crop.
