ICECRD ACTIVITIES – Bogor, July 23, 2021. The Indonesian Spice & Medicinal Crops Research Institute (ISMCRI) held a Virtual Technical Guidance with the theme “Control of OPT Ginger (Leaf Spots and Rhizome Flies) with 669 participants attending the zoomeeting and youtube. Participants come from various professions, and various domicile origins throughout Indonesia. Each participant gets free materials and certificate facilities.
This Technical Guidance activity was opened by the Head of the ISMCRI, Dr. Ir. Evi Savitri Iriani, MSi and accompanied by Moderator Dr. Retno Djiwanti and the Resource Persons. The materials presented in this Technical Guidance include 1) Introduction to Ginger Leaf Spot Disease and its Control with the resource person Marlina Puspita Sari, SP., MSc.; 2) Mimegralla coeruleifrons Macquart (Diptera: Micropezidae) Rhizome Flies on Ginger Plants and their Control with resource persons Rismayani, SP, M. Agr.
Dr. Evi Savitri Iriani, MSi in her speech said that the topic that was raised for technical guidance at this time was Ginger because during the COVID-19 pandemic, Ginger is a commodity that is much sought after by the public. Based on several studies, ginger has many benefits including increasing immunity, having high anti-oxidants, anti-inflammatory and anti-microbial properties. On this occasion, the ISMCRI tries to convey information on innovations, especially the handling of pests on ginger, hopefully the information conveyed through this technical guidance will benefit the participants,” said Dr. Evie Savitri.
In her presentation, Marlina Puspita Sari, SP., MSc said that leaf spot disease is caused by a plant parasitic fungus. Environmental conditions, plant age and the type of ginger planted affect the damage and the dominant type of fungus in an area. Integrated control includes 1) Handling and selection of seeds; 2) tillage of the soil to bury the rest of the affected plants; 3) Spacing and fertilizing according to SOP; 4) Routine monitoring; 5) Application of fungicides when necessary.
The rhizome fly Mimegralla coeruleifrons (Diptera: Micropezidae) is one of the important pests on ginger plants. Rhizome fly attacks always coincide with the bacterium Ralstonia solanacearum. The use of vegetable pesticides based on citronella oil was able to achieve a mortality rate of rhizome fly pests above 80% on the third day after application, “said Rismayani, SP, M. Agr in her presentation.
Hopefully the presentation of the material and the discussion presented can improve the quality, bring benefits and revive the agricultural sector, especially ginger in Indonesia, which is growing and advancing. (Anjas)
