I have several 10" diameter king and queen palms that have a fungus. How much should I apply and how?
Monterey Liqui-Cop can be applied to Queen palms for Exosporium leaf spot, Phytophthora bud rot at 2 tsp per gallon. Per the product label: "Begin application at first sign of disease and repeat at 7-14 day intervals as needed. Use shorter interval during periods of frequent rains or when severe disease conditions persist. Do not apply more than 460 tsp. of LIQUI-COP (0.46 lbs. metallic copper) per 1,000 sq. ft. per year".
