Rigidoporus microporus is the main causal of white root disease (WRD) in rubber trees (Hevea brasiliensis). The present study investigates use rhamnolipid, a biosurfactant produced by Pseudomonas aeruginosa USM-AR2 against R. microporus. In vitro dose-responses towards rhamnolipid were determined on different isolates using poisoned food technique (PFT). Inhibition mycelial growth was found to ...

Pest and disease attacks are one of the obstacles in increasing shallot production Palu Valley, Central Sulawesi. Farmers still rely on use synthetic pesticides to control pests diseases, which results a high demand for insecticides fungicides. This community service aims disseminate pest technology with bioinsecticide Beauveria bassiana biofungicide Trichoderma, as well train farmers develop a...

While consumers are interested in organic or biorational alternatives to synthetic fungicides for the control of diseases of ornamentals as well as vegetables and tree fruits in residential landscapes, relatively few field trials have been conducted to establish their performance against ornamentals diseases. Weekly applications of Armicarb® 100 (potassium bicarbonate) controlled powdery mildew...

Lysobacter capsici AZ78 has considerable potential for biocontrol of phytopathogenic microorganisms. However, lack of information about genetic cues regarding its biological characteristics may slow down its exploitation as a biofungicide. In order to obtain a comprehensive overview of genetic features, the L. capsici AZ78 genome was sequenced, annotated and compared with the phylogenetically r...

Corynespora causes leaf fall disease in rubber plants. Control can be done with bio fungicides and potassium fertilizer. This study aims to determine the effectiveness of essential oils fertilizer controlling disease. The research was conducted from January December 2018 Landak Regency, West Kalimantan. used a randomized block design 13 treatments repeated 3 times. treatment is without biofungi...
