By Lauren Diepenbrock As the March bloom tapers off and fruit begin to set, it is time to think about lebbeck mealybug management to protect developing fruit. Damage to setting fruit causes malformed fruit that are often aborted or not marketable if they continue development (Figure 1). Early-season management is critical to both reducing early fruit damage and to maintaining …
