“…However, limited to cultivation methods, there are also aspects that can be considered in a narrower context. Such cultivation methods would include, among others, appropriate plant nutrition and soil fertility management combined with crop rotation [54], appropriate irrigation management, and timing of sowing or planting in order to reduce pests. Precision farming like spraying of hot-spots and weeding with optical detectors has also been demonstrated to be effective in banana cultivation [55].…”

Conventional banana farming is pesticide-intensive and leads to high exposure of farmworkers. Ecuador is the world’s biggest exporter of bananas. In this field study in 5 communities in Ecuador, we recorded potentially pesticide-associated subjective health symptoms in farmworkers and compared pesticide users to workers in organic farming. With one exception, symptom rates were always higher in the pesticide-exposed group. Significance was reached in 8 out of 19 investigated symptoms with the highest odds ratios (and smallest p-values) for local irritation like skin and eye irritation (OR = 3.58, CI 1.10–11.71, and 4.10, CI 1.37–12.31, respectively) as well as systemic symptoms like dizziness (OR = 4.80, CI 1.55–14.87) and fatigue (OR = 4.96, CI 1.65–14.88). Moreover, gastrointestinal symptoms were reported more frequently by pesticide users: nausea (OR = 7.5, CI 1.77–31.77) and diarrhea (OR = 6.43, CI 1.06–30.00). The majority of farmworkers were not adequately protected from pesticide exposure. For example, only 3 of 31 farmworkers that had used pesticides recently reported using gloves and only 6 reported using masks during active spraying. Improved safety measures and a reduction in pesticide use are necessary to protect the health of banana farmworkers.

“…Banana with different crop rotations can effectively reduce banana Fusarium wilt (Hong et al 2020;Fan et al 2020). In this study, the results of pot experiments revealed that pineapple-banana rotation and residue amendment systems could signi cantly enhance the suppression of Fusarium wilt disease compared with banana monocropping and residue addition.…”

“…In addition, the abundance and activity of Pseudomonas, Sphingomonas, Penicillium and Trichoderma spp. were found to be signi cantly higher than the Fusarium number in the soil (Hong et al 2020). The soil microbiome can enhance rhizosphere immunity, improve soil fertility and crop yield, maintain the persistence of plants, animals and humans, and protect soil health (Bender et al 2016).…”

Aims The large outbreak of banana Fusarium wilt has become a bottleneck limiting the industry’s development, and crop rotation is a cost-effective and essential measure to overcome the obstacles of banana crop monoculture. The present work was carried out to explore the mechanisms of how changes in physicochemical properties and the reestablishment of soil microorganisms in high-incidence soils are affected by crop rotation and plant residue. Methods In this study, pineapple-banana crop rotation and pineapple residue amendment were used to alleviate banana Fusarium wilt, and their effects on bacterial and fungal communities were studied using the MiSeq Illumina sequencing platform. Results Both pineapple-banana rotation and residue addition significantly reduced disease incidence. Moreover, pineapple rotation and residue amendment altered the bacterial and fungal community composition. The taxonomic and phylogenetic alpha diversity of bacteria and fungi significantly increased against disease suppression and nutrition competition. The relative abundances of the Burkholderia, Pseudomonas, Elaphocordyceps, Penicillium, and Talaromyces genera were higher, and the number of Fusarium was significantly lower in rotational soil than in banana monoculture soil. Finally, linear models (LM) was used to show that the Burkholderia and Talaromyces in crop rotation, and Aspergillus in residue amendment have significant negative relationship to disease incidence, which plays a key role in Fusarium reduction. Conclusions To consider the economic benefits and protect the vitality of the soil, this study suggested that pineapple-banana rotation and pineapple residue amendment both could be considered for the sustainable management of banana wilt.

“…The majority genera included Aleuria, Chrysosporium, and Mortierella under all treatments (Figure 4D). Many potential beneficial antagonists are from Acremonium, Penicillium, Guehomyces, Trichoderma, and Mortierella (Jinu and Park, 2014;Hong et al, 2020;Huang et al, 2020;Li et al, 2020).

Soil treatment with disinfectants has been used for controlling soilborne phytopathogens. Besides suppressing specific pathogens, how these disinfectants impact soil health, especially soil microbial communities, is yet to be systemically determined. The objectives of this study were to examine the effects of three representative disinfectants, including the dazomet fumigant, fenaminosulf fungicide, and kasugamycin antibiotic on chemical properties, enzymatic activities, and microbial communities in soil for cucumber cultivation. Results showed that 14 days after soil treatment with these chemicals, residual content of dazomet and kasugamycin quickly declined in soil and were undetectable, while fenaminosulf residues were found at 0.48 ± 0.01 mg/kg. Total nitrogen and total carbon increased in soil after dazomet treatment. Urease and sucrase activities were significantly restrained after disinfectant application. The disinfectants did not significantly change the taxon of predominant bacteria and fungi but altered the relative abundance and diversity of soil microbiome, as well as microbial interspecific relationships. Moreover, cucumber cultivation enhanced the overall soil microbial diversity and enzymatic activities, which diminished the difference of soil microbiome among four treatments. The difference in soil microbial diversity among the four treatments became smaller after planting cucumber. Thus, soil microbial communities were affected by soil disinfectants and gradually recovered by cucumber application.
