When applying Sevin SL Carbaryl Insecticide to apples for Japanese beetles you will use 1 ½ to 3 quarts per acre (1 1/8 to 2 1/4 fl oz per 1,000 sq ft). The product label states on apples, avoid use during the period from full bloom until 30 days after full bloom unless fruit thinning is desired. Use during this period also may result in fruit removal. Repeat applications as necessary up to a total of 8 times per crop (including thinning sprays on apples) but not more often than once every 14 days.
