The product label of Bonide Captan does not specify a maximum amount of applications per season. For more information on the reasoning, you may contact the manufacturer (Bonide) directly at 315-736-8231 as they will be an expert on their own product.

Brooks fruit spot, sooty blotch, fly speck, black rot, black pox, botryosphaeria rot, bitter rot - Use 1 1/2 Tbs. per gal. of water. Apply in second and late cover sprays 10 to 14 day intervals. May be applied up to harvest. Note: Do not apply this product with or closely following, or in alternation with wettable sulfur products on sulfer-sensitive varieties of apples such as Baldwin, Kind, Red Delicious, Staymen, etc. as severe injury and defoliation may occur.
