Open pruning will aid in
SWD management, as will prompt harvest of ripe berries.
Spray timing must be at least every 7 days in many cases. Rotate modes of action in order to delay the development of pesticide resistance. There is a 24(c) label for malathion 8F allowing 2.5 pt for SWD. Addition of table sugar at the rate of 30 oz per 100 gal will aid in efficacy of chemical control of SWD. |
