“…Factors that contribute to the low productivity of rubber plants are the presence of pest and disease assault, inadequate understanding of routine care, such as fertilization and insect eradication, and less intensive disease [5]. It is estimated that crop losses caused by pests and diseases range anywhere from 17 to 30 percent across the globe [6]. Pathogenic fungal infections such as Phytophthora-caused aberrant leaf fall (ALF) and shoot rot, Corticium salmonicolor-caused pink disease, Corynespora-caused leaf disease, and powdery mildew (Oidium sp.…”

This research aims to determine the influence of climate in West Kutai, Indonesia on the intensity of disease attack Upas Fungus (Corticium sp.) pathogen on 4-year-old and 7-year-old rubber plants. The study began in 2015, with a 4-year-old rubber plant and continues in 2018 with a 7-year-old rubber plant. The methodology is to inventory 500 rubber plants in two neighboring locations to determine the incidence and severity of disease caused by Upas Fungus in 2015. The results indicated that an invasion of pathogenic Upas Fungus attacked rubber plants starting at the age of 4 years in 2 places and the age of 4 years in another location. Symptoms included substantial eruptions of tree trunks that finally dried up. The inventory and calculation results indicate that the attack frequency at position 1 is 1.20 % with an attack intensity of 0.90 %, and the attack frequency at location 2 is 2.40 % with an attack intensity of 1.80 %. The correlation test revealed an inverse (negative) relationship between temperature and attack intensity, with a coefficient value of 0.721, and a directly proportional (positive) relationship between humidity and intensity, with a coefficient value of 0.754 and vice versa, between rainfall and intensity there is an inverse (negative) relationship that is not significant with a coefficient value of 0.199 and vice versa.

Preliminary Studies on Suppression of Important Plant Pathogens by Using Pomegranate and Avocado Residual Peel and Seed Extracts

et al. 2022

Potential synergistic action of aqueous extracts of pomegranate peel (PP), avocado peel (AP), and avocado seed (AS) wastes isolated by microwave-assisted extraction were assessed in in vitro and in vivo assays as biocontrol agents against several plant pathogenic fungi. The study findings contribute to the utilization of a value-added industrial byproduct and provide significant value in advancing the development of new plant protecting compositions that benefit from the synergistic effects between two important plant species that contain several natural bioactive compounds. More specifically, the in vitro results proved that the use of 100%-pure (PP) extracted waste affected the mycelium growth of Penicillium expansum. Furthermore, mycelium growth of Aspergillus niger was decreased by 10.21% compared to control after 7 days of growth in medium agar containing 100% AP and extracted waste. Moreover, mycelium growth of Botrytis cinerea was affected by equal volume of avocado extraction wastes (50% peel and 50% seed) only at the first 3 days of the inoculation, while at the seventh day of the inoculation there was no effect on the mycelium growth. Equal volumes of the examined wastes showed decreased mycelium growth of Fusarium oxysporum f.sp. lycopersici by 6%, while Rhizoctonia solani mycelium growth was found to be the most sensitive in PP application. In addition, the in vivo assay shown that PP extract suppresses damage of tomato plants caused by R. solani followed by extracted wastes from AP. Based on the research findings, it can be argued that PP and AP extracts can be used as natural antifungals instead of dangerous synthetic antifungals to effectively treat phytopathogens that cause fruit and vegetable losses during cultivation.
