“…Fusarium proliferatum, is a widespread soilborne disease that causes serious damage and significant economic losses to Ba kich production in Vietnam in general and in Thai Nguyen in particular [1]. Several bio-products have been applied for the management of FRRBK in Thai Nguyen province.…”

“…Three isolates of F. proliferatum, BKVN (Ba kich growing in Vo Nhai district), BKDT (Dai Tu district), and BKPL (Phu Luong district), which were previously identified as causal agents of FRRBK in Thai Nguyen province [1], were cultured on potato dextrose agar (PDA) plates for three days at 25 0 C in dark conditions. A piece of PDA medium containing mycelium of each isolate was grown in potato dextrose broth at 25 0 C with shaking at 120 rpm.…”

“…Tebuconazole also suppressed disease incidence of FRRBK in field conditions; however, its efficacy was lower than that of either prochloraz or metconazole ( Table 5). F. proliferatum has been reported as the causal pathogen of FRRBK in Vietnam [1]. To investigate the effects of different fungicides on F. proliferatum, DMI (metconazole, prochloraz, and tebuconazole) and QoI (kresoximmethyl and pyraclostrobin) fungicides were evaluated in this study.…”

Fusarium proliferatum has been identified as the causal pathogen of Fusarium root rot of Ba kich (Morinda officinalis) (FRRBK). No studies are available regarding the effectiveness of chemical treatments on the disease incidence of FRRBK. The efficacy of five active ingredients (metconazole, prochloraz, tebuconazole, kresoximmethyl, and pyraclostrobin) from two chemical groups (demethylation inhibitors and quinone outside inhibitors) in reducing three isolates (BKVN, BKDT, and BKPL) of F. proliferatum mycelial growth was tested in vitro. The results indicate that only metconazole, prochloraz, and tebuconazole are highly effective in inhibiting the mycelial growth of F. proliferatum. These were selected for investigation of their efficacy with regard to the disease incidence of FRRBK in pot and in field conditions. Prochloraz and metconazole showed the highest efficacy and significantly suppressed the disease incidence of FRRBK in pot and in field conditions.

“…Fusarium root rot of Ba kich (FRRBK) is a widespread soil-borne disease, which can cause serious damage and huge economic losses to Ba kich production in Viet Nam. Fusarium proliferatum (FP) has been identified as the causal pathogen of FRRBK [1]. It was shown that long periods of continuous cropping of Ba kich with high planting density and intensified soil acidification from chemical N fertilization and less use of organic manures may change in the soil microbiome, subsequently leading to disease outbreak [1].…”

Background: Fusarium root rot disease in Indian mulberry (Morinda officinalis How.) (FRRBK), caused by Fusarium proliferatum (FP), is widespread and responsible for serious economic losses in Viet Nam. The efficacy of a new bioproduct named MICROTECH-1(NL) is compared with other commercial products for suppression of FP under in vitro, pot, nursery as well as in the field conditions. Results: In in vitro antagonistic assay, MICROTECH-1(NL) significantly inhibited the mycelial growth of FP (72.38%). Under pot conditions, the efficacy of all the bio-products was significantly higher when applied prior to pathogen inoculation. The disease severity of treatments with double application of MICROTECH-1(NL) (applied both in the nursery and in the pot soil) was only 15.56%, significantly lower than control (80%). Thus, the application of MICRO-TECH-1(NL) significantly reduced the incidence of FP and markedly increased the number of plant beneficial bacteria and actinobacteria in rhizoplane of M. officinalis compared to untreated control. In the field conditions, double application of MICROTECH-1(NL) (both in the nursery and in the field soils) significantly decreased disease severity in comparison to single application in nursery or field. Conclusion: The most effective treatment was double application of MICROTECH-1(NL), which significantly reduced the disease severity and FP population in roots of M. officinalis and increased the population of plant beneficial microbes.
