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.

Apply in prebloom, bloom, petal fall and first cover sprays at 10 to 14 day intervals. 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.
Apples (Western U.S.) Primary scab - Use 1 to 1 1/2 Tbs. per gal. of water. For secondary scab in mid-summer coverage spray - Use 1 Tbs. per gal. of water. (Pacific Northwest): Bull's eye rot, botrytis rot - Use 1 Tbs. per gal. of water. Make 1 or 2 applications with late cover sprays and 1 final spray prior to harvest. May be applied up to harvest.
