GENERAL USE INFORMATION
Serenade Opti is a broad spectrum, preventative product for the suppression of many plant diseases. Serenade Opti may be applied as a foliar spray alone, or in an alternating spray program with other registered crop protection products. When conditions are conducive to heavy disease pressure, use Serenade Opti in a rotational program with other registered fungicides. Serenade Opti may be applied with ground or aerial application equipment.

MIXING INSTRUCTIONS
MIXING: Serenade Opti must be diluted with water for spray applications and may be used in spray equipment commonly used for making ground applications. Partially fill the spray tank with clean water and begin agitation. Add the specified amount of Serenade Opti to the tank. Finish filling the tank to the desired volume to obtain the proper spray concentration. Maintain agitation continuously while spraying. Do not allow spray mixture to stand overnight or for prolonged periods.

APPLICATION INSTRUCTIONS – Agricultural Use:
GENERAL: Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment-and-weather–related factors determine the potential for spray drift. The applicator and the grower/treatment coordinator are responsible for considering all of these factors when making decisions. Where provinces/territories have more stringent regulations, they should be observed.
As this product is not registered for the control of pests in aquatic systems, DO NOT use to control aquatic pests.
GROUND: Thorough coverage is essential for Opti disease control. To achieve good coverage, use the appropriate spray pressure, liters per hectare, nozzles, nozzle spacing and ground speed. Consult spray nozzle and accessory catalogues for specific information on proper equipment calibration.
AIR: Use the application rate indicated for the appropriate crop in sufficient water to achieve thorough coverage.
