Management of rhizome rot disease of ginger using eco-friendly natural products

Abstract

Rhizome rot caused by Pythium spp and Fusarium spp is one of the most devastating diseases of ginger in most of the ginger growing areas of the Nepal. Realizing the context for development of alternative control strategies to reduce dependency on synthetic fungicides, a field experiment on management of rhizome rot disease of ginger using eco-friendly natural products was conducted at GRP, Kapurkot, Salyan during 2012/2013. Fresh and fermented extract of Artemesia vulgaris Linn (Titepati), Urtica dioica (Sisnoo), Zanthoxylumarmatum DC. (Timbur), Allium cepa L., (Onion), Allium sativum L. (Garlic), Capsicum annuum L. (Chili), Nicotiana tabacum (Tobacoo) along with Jeevatu (a mixed product of beneficial microbes) and biofit were tested in the experiment. Experiment was conducted in the naturally inoculated sick plot in RCB design with eight treatments replicated thrice. Each experimental plot area was 3m x1.5m (4.5m2). Observation on plant number, tiller clump-1, plant height, disease incidence, fresh rhizome yield, disease rhizome yield andmother rhizome yield were recorded and evaluated using statistical analysis tool MSTAT-C. Fresh rhizome yield for all the treatments were found lower than national average. Jeevatu (5%) treated plot had highest fresh rhizome yield (7.70 m t ha 1) followed by (onion+garlic+chili) + urine (1:3) fermented extract (4.88 mt ha 1). Similarly, rhizome rot scale (1.66), disease incidence (41.96%) and the diseased rhizome yield (0.74 mt ha 1) was shown least on jeevatu treated plot. Highest disease rhizome yield (2.37 mt ha 1) was obtained in the treatment titepati + urine (1:2) fermented extract followed by control(2.07 mt ha 1).

Adoption of Good Agricultural Practice to Increase Yield and Profit of Ginger Farming in Nepal

“…Turmeric rhizome yields were found significantly highest (42.71 t•ha -1 ) in the treatment applying vermicompost along with synthetic fertilizers in southern India (Isaac & Varghese 2016). Similarly, some studies found that various Trichoderma species are effective to manage rhizome rot disease in ginger and turmeric (Bharathi & Sudhakar 2011;Acharya et al 2016;Thakur et al 2017).…”

A comprehensive review on soft rot disease management in ginger (Zingiber officinale) for enhancing its pharmaceutical and industrial values

“… Fusarium oxysoprum f. sp. zingiberi Pythium aphanidermatum [ 91 ] Acorus calamus Allamanda cathertica Lasia spinosa Laurus nobilis Pythium aphanidermatum [ 92 ] Alamonda leaf extract Fusarium oxysporum [ 93 ] Artocarpus lakoocha Hemedesmus indicus Elaegnus kologa Schlecht Polyalthia longifolia Croton roxburghii Balak.

“…Additionally, Neem leaves were found to have certain sulfurous substances that had fungicidal capabilities, according to Pant et al [ 90 ]. Acharya et al [ 91 ] reported the activity of various plant extracts such as Arthemesia vulgaris Linn, Urtica dioica, Nicotiana tabacum, and Capsicum annuum Linn against Pythium and Fusarium species that cause soft rot of ginger. In another study, Kumar et al [ 92 ] demonstrated the antifungal activity of extracts of Acorus calamus, Allamanda cathertica, Lasia spinosa, and Laurus nobilis against Pythium aphanidermatum that causes ginger soft rot disease.…”

KERAGAMAN DAN KELIMPAHAN JAMUR PADA JAHE MERAH (Zingiber Officinale var Rubrum) DI KECAMATAN SANGATTA SELATAN KABUPATEN KUTAI TIMUR

“…Patogen dapat menyerang tanaman rimpang, baik di persemaian maupun di lahan pertanian, yang dapat menyebabkan kematian rimpang dan tanaman. Penyakit rimpang dapat menurunkan produksi jahe dan menurunkan hasil panen sebesar 50% hingga 90% (Acharya, et al, 2016). Pengembangan budidaya jahe merah untuk memenuhi kebutuhan industri biofarmasi memerlukan metode biologis untuk mengendalikan penyakit tanaman (Marwan, et al, 2023).…”
