“…This study revealed that Fusarium solani causes gummosis in Eucalyptus camaldulensis, which was not reported till now. However, it has been reported to cause Gummosis in rubber tree (Huang et al, 2016). In this study, two previously unreported Fusarium species were discovered as a causative organisms of stem canker in Bombax, ceiba and dieback in Eucalyptus camaldulensis.…”

The structure and composition of healthy ecosystems, as well as the production and protection equations, are all influenced by forest diseases. This study was conducted in a planted forest in Ghorahi, Dang, Nepal, to document pathogenic fungi associated with economically important tree species, viz. Tectona grandis, Dalbergia sissoo, Eucalyptus camaldulensis, and Bombax ceiba. By using a stratified random sampling technique, a total of 10 quadrats, with a sample size of 20x20m, were located. Each plot was then divided into quadrats of 10x10m. The diseased samples were collected and brought to the laboratory. A total of 10 fungal pathogens were identified. Of them, eight pathogens were identified to species level and two to generic level. These 10 pathogens are Erysiphe tectonae (powdery mildew), Oliveatectonae (leaf rust), Alternaria alternata (leaf blight), Colletotrichum gloeosporioides (leaf blight), Cylindrocladium reteaudii (leaf blight), Fusarium sp. (dieback), Alternaria alternata (leaf blight), Fusarium solani (gummosis), Fusarium sp. (canker), and Maravalia achroa (leaf rust).

Abstract. Yulia E, Mahmudah AI, Rahayu A, Nasahi C, Maharani Y, Suganda T, Widayat D. 2022. Phytopathogenic fungi as potential biocontrol agents against an invasive weed, Asystasia gangetica, at Sakambangan rubber plantation in Garut, West Java, Indonesia. Biodiversitas 23: 4532-4538. Many weeds are invasive species causing both economic and ecological losses. Asystasia gangetica is one of invasive species from the Acanthaceae family and has now been established as one of the most important weeds of rubber plantation. Mechanical control of A. gangetica is ineffective, while chemical control is harmful to the environment. Thus, it is imperative to explore alternative control methods. This study aimed to carry out an inventory of pathogenic fungi isolated from A. gangetica and test their pathogenicity to A. gangetica and rubber seedlings. This research was conducted from November 2021 to February 2022. The methods used were field observation and laboratory test conducted at the Sakambangan rubber plantation, Garut District, West Java and the Phytopathology Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Padjadjaran. Pathogenicity test was carried out using water-culture method to grow the tested plants without soil. Fungi isolated from A. gangetica identified as Fusarium sp., Pestalotiopsis sp., Colletotrichum sp. and Cercospora sp. were tested to be pathogenic to A. gangetica, and deemed potential biocontrol agents. However, Pestalotiopsis sp. and Cercospora sp. were also pathogenic to rubber seedlings which make them ineligible as biocontrol agents for A. gangetica in rubber plantations.

“…En este estudio la identificación y cuantificación realizada de hongos presentes en el follaje de las tres coberturas a través de nueve muestreos en el tiempo mostró que los hongos más abundantes correspondieron a E. sorgui y Cladosporum spp, considerados como no limitantes de cultivo del caucho, a diferencia del tercer hongo encontrado correspondiente a Fusarium sp. el cual en los últimos años se ha asociado a necrosis del tallo, chancros y escurrimiento de látex (Huang et al, (2016). Estos resultados indican que el establecimiento de coberturas, especialmente Desmodium sp., en plantaciones de caucho en etapa productiva sería contraproducente ya que favorecería la disponibilidad de inoculo de Fusarium sp., el cual podría llegar a afectar el panel de sangría (Li et al, 2014).…”

Se evaluó el efecto de las coberturas Mucuna bracteata, Desmodium sp. y Pueraria phaseoloides en el crecimiento y su influencia en el estado fitosanitario de un cultivo de caucho natural de dos años de edad en la altillanura colombiana. En condiciones de libre exposición se establecieron tratamientos por cobertura con tres repeticiones y tres réplicas con un control. Las variables respuestas fueron perímetro y la altura total del árbol; se realizaron muestreos del follaje de las coberturas para identificar y cuantificar hongos presentes. Adicionalmente, se hicieron inoculaciones de Colletotrichum gloesporioides en las tres coberturas en condiciones semicontroladas. Se encontró que las tres coberturas generan un leve aumento en la materia orgánica del suelo y favorecen el desarrollo de los árboles. Los hongos más frecuentemente aislados correspondieron a Cladosporium sp., E. sorgui y Fusarium sp. Las inoculaciones mostraron que las tres coberturas son susceptibles a C. gloesporiodes.
