Efficacy and economics evaluation of seed rhizome treatment combined with preplant soil fumigation on ginger soilborne disease, plant growth, and yield promotion

Abstract

BACKGROUND Ginger (Zingiber officinale Roscoe) is widely planted around the world. Owing to continuous planting, ginger is seriously affected by soilborne fungi, bacteria, and nematodes. Although preplant soil fumigation is an effective prevention strategy of soilborne diseases, individual fumigant and technology could not provide effective control of ginger soilborne disease. In our research, different combinations of soil fumigants and seed rhizome treatments were evaluated by monitoring the soil pathogens population, ginger growth, yield, and estimation of economic benefits. RESULTS Soil fumigation effectively reduced the population of soilborne pathogens, and chloropicrin had a better control effect on soilborne pathogens than dazomet did. Preplant soil fumigation and seed rhizome treatment not only provide good control of soilborne disease, but also reduced the incidence of plant foliar pest and disease. Average yield increase rate of seed rhizome treatment was 12.0%; the highest yield increase was 24.4%. The average cost of seed rhizome treatment only increased by about 2.86%, but the rate of net revenue increase for the seed rhizome treatment reached up to 19.1%. CONCLUSION Seed rhizome treatment is a very cost‐effective soilborne disease control technology. In the management of soilborne diseases, the combined application of soil fumigation and seed rhizome treatment can reduce the risk of crops infected by soilborne diseases and ensure high and stable crop yields. © 2021 Society of Chemical Industry.

Exploring the Heat Shock Transcription Factor (HSF) Gene Family in Ginger: A Genome-Wide Investigation on Evolution, Expression Profiling, and Response to Developmental and Abiotic Stresses

“…Nevertheless, further experimental verification is necessary to confirm these findings. The rhizome serves as the economic organ of ginger and selecting seed ginger with robust rhizome buds for planting is an effective method to achieve high ginger yields [ 65 ]. Based on the expression pattern of ZoHSF01 , we observed relatively high expression levels in rhizome buds, the first internode, and the secondary internodes, indicating its potential role in the process of rhizome enlargement.…”

Application of microbial organic fertilizers promotes the utilization of nutrients and restoration of microbial community structure and function in rhizosphere soils after dazomet fumigation

“…With the improvement of agricultural modernization, intensive production, characterized by monoculture planting of crop types and high replanting index, has gradually become the mainstream agricultural production model, which has led to the frequent occurrence of soil-borne diseases, causing serious effects on crop yield and quality, and has now become an important bottleneck limiting sustainable agricultural development ( Harrier and Watson, 2004 ; Haas and Défago, 2005 ; Piotr et al, 2014 ). Crop succession leads to continuous accumulation of pathogens in soil; for example, eggplant crop succession leads to severe occurrence of bacterial wilt ( Wu et al, 2020 ) and blight ( Bogoescu et al, 2014 ), watermelon crop succession leads to severe occurrence of wilt ( Karki et al, 2021 ), and ginger crop succession can lead to severe ginger plague ( Yan et al, 2021 ). This not only breaks the soil nutrient balance but also deteriorates the soil biological traits, which eventually results in the collapse of the soil microcosm and causes serious harm to crop yield and environmental safety ( Bron et al, 2011 ; Roeland et al, 2012 ).…”

Benzalkonium Chloride and Benzethonium Chloride Effectively Reduce Spore Germination of Ginger Soft Rot Pathogens: Fusarium solani and Fusarium oxysporum

“…Ginger (Zingiber officinale Roscoe) is a significant cash and spice crop in certain tropical and subtropical countries [1,2]. China is the second-largest ginger producer in the world, with about 3 million hectares under ginger cultivation [3], and accounts for about a quarter of the world's output [4]. Continuous farming causes ginger cultivation to be impacted by a variety of soil-borne diseases, including bacteria and fungi [3].…”

Continuous farming causes ginger cultivation to be impacted by a variety of soil-borne diseases, including bacteria and fungi [3]. As a prevalent disease in large ginger soils, the ginger disease soft rot caused by Fusarium solani and Fusarium oxysporum [5][6][7][8] poses a great threat to the yield and quality of ginger.…”
