Pest management before harvest and insecticidal dip after harvest as a systems approach to quarantine security for red ginger.

摘要: A systems approach consisting of insecticide application before harvest and use an insecticidal dip after provided quarantine security that eliminated all insect pests red ginger, Alpinia purpurata (Vieill.) K. Schum., including the banana aphid, Penta Ionia nigronervosa Coquerel; cotton Aphis gossypii Glover; citrus mealybug, Plano coccus citri (Risso); obscure Pseudococcus affinis (Maskell); longtailed longispinus (Targioni-Tozzetti); cardamom thrips, Sciothrips cardamomi (Ramakr); black earwig, Chelisoches Mario (F.); ant, Technomynnex albipes (F. Smith). Insecticide consisted chlorpyrifos 50 dry flowable (DF) applied to foliage at 2-wk intervals, or 20 microencapsulated (MEC) as barrier treatment. 5-min with a combination fluvalinate 2.0 (F) soap (potassium salts fatty acids) agitation killed any remaining survivors long field populations had <6% mealybug infestation, <33% aphid <70% infestation. These procedures plus final inspection flowers for live insects ensured pest-free ginger met requirements.
