Description

Monterey Liqui-Cop is a copper fungicide garden spray that controls many diseases attacking citrus, fruits, nuts, vegetables, and ornamentals.

The control of diseases with fungicides is based on prevention. Plant surfaces must be covered entirely with the fungicide to prevent infection successfully. Keep in mind, copper pesticides are considered preventative, not curative, of plant diseases.

Use the highest indicated rate when disease incidence is high or expected to be, depending on rainfall and temperature. The lower rate is suitable for general preventive sprays under normal conditions. Since weather conditions and disease incidence vary, consult your Agricultural Extension Service for timing and initial application.

Contains: Copper Ammonium Complex – 27.15%

pollinators?

Are you asking if it will harm pollinators such as bees? If so There should be no problem using Monterey Liqui-Cop in an area where there are bees. We would advise avoiding spraying directly to flower blossoms or during times when pollinators are present as the direct spray may have toxicity to bees or other insects if contacted directly
