“…Moreover, the combination of Trichoderma spp. and potassium fertilizer extended the incubation time and decreased P. palmivora specks on cocoa leaves by as much as 75.37% [18]. In a different review, Choudhary et al 2021 [19] highlighted the effective management of citrus gummosis/foot rot and maximized harvest using T. asperellum as a soil treatment.…”

Phytophthora palmivora-induced root and basal stem rot pose a significant threat to the survival of Soe mandarin plants in East Nusa Tenggara Province, Indonesia. We isolated four Trichoderma species, five Bacillus, and 13 Pseudomonas isolates from the rhizosphere of healthy Soe mandarin. This study pursued two main objectives: (a) assessing the inhibitory capabilities of indigenous Trichoderma spp., Bacillus, and Pseudomonas towards P. palmivora in vitro, and (b) investigating the combined efficacy of Trichoderma spp., Bacillus, and Pseudomonas in controlling P. palmivora in a pot trial. Results revealed that four Trichoderma species (T. asperellum, T. hamatum, T. harzianum, and T. viride) significantly inhibited the growth of P. palmivora. Notably, T. asperellum exhibited the highest inhibition, at 84.31%, followed closely by T. harzianum (84.11%), T. viride (83.67%), and T. hamatum (80.28%). Bacillus and Pseudomonas exhibited varying levels of inhibition to P. palmivora growth in vitro, with the most substantial inhibition observed in Bacillus 1, followed by Pseudomonas 6. In the subsequent pot trial, the application of Trichoderma, Bacillus, or Pseudomonas, either individually or in combination, significantly increased the height increment and reduced the disease incidence caused by P. palmivora in Soe mandarin seedlings.

“…Acrhomobacter, Acinetobacter, Agrobacterium, Bacillus, 86 Brevibacterium, Microbacterium, Pseudomonas, Xanthomonas and other species have also been discovered to have the capacity to suppress phytopathogenic nematodes (Yadav et al, 2017;Harni et al, 2023). Istifadah et al, 2018 Studies on endophytic bacteria invading plant roots and inhibiting nematode development are few.…”

The biological management of plant diseases has developed into a separate scientific and technological discipline, and in recent years, this change has happened quickly. A form of bacterium known as a bacterial endophyte may colonize any portion of a plant without causing any symptoms or harm to the host plant. Endophytic bacteria have been discovered by several researchers, and there is growing evidence that they can stop a variety of plant diseases from growing and functioning. Endophytes have a variety of benefits including growth-increasing and disease-hampering properties. Researchers’ interest in this field is growing as a result of its potentially to be utilized as an alternative to synthetic fungicides. This review's main objectives are to chart the development of endophytic bacterial research and give scientists access to current knowledge that will spur further investigation. Endophytic bacteria are employed to control plant diseases including wilt, rot and post-harvest damage, as well as nematode infestation. Endophytic bacteria are also used to control nematodes and postharvest diseases. With an emphasis on endophytic bacteria, this review explains the diverse mechanisms of bacterial endophytes to shield the plant from biotic infection.

“…Instead of using a single crop management strategy, researchers have to combine Trichoderma spp. with potassium fertilizer to control cocoa black pod rot in Indonesia (Harni et al, 2020) (Table 2). Generally, potassium deficiency weakens plant resistance, allowing pathogens to penetrate (Damiri et al, 2011).…”

Phytophthora palmivora is a destructive plant pathogenic oomycete that has caused lethal diseases in a wide range of hosts. It is a pan-tropical distributed pathogen that can infect plants at all growth stages. Extensive studies have linked P. palmivora to severe diseases in several crops, such as black pepper, rubber, cocoa, and durian, causing global economic losses. This review covers the following topics in depth: (i) P. palmivora as phytopathogen; (ii) identification and infection mechanism in rubber, cocoa, and durian; and (iii) management and control applied for P. palmivora diseases. Effective management strategies were studied and practiced to prevent the spread of P. palmivora disease. Genetic resistance and biocontrol are the best methods to control the disease. A better understanding of P. palmivora infection mechanisms in our main crops and early disease detection can reduce the risk of catastrophic pandemics.
