How often can I spray Monterey Liqui-Cop for rust on my avocado tree?

Answer:

Monterey Liqui-Cop is only labeled for Anthracnose on avocados. You will use 4  tsp per gallon of water. Per the Label, Apply when the flower buds begin to swell and continue at monthly intervals until August. Do not apply more than 430 tsp. of LIQUI-COP (0.43 lbs. metallic copper) to Avocados per 1,000 sq. ft. per year.
