Abstract

Food crops are plants grown for consumption by humans and animals. These crops face threats from both abiotic and biotic factors. Therefore, environmentally friendly alternative controls are needed, such as enhancing plant resistance using Trichoderma spp. This systematic literature review provides information on the effects of Trichoderma spp. application on plant physiology, particularly focusing on defense enzymes in food crops in the Asian region. Articles on the effects of Trichoderma application on food crop defense enzymes in Asia were retrieved from PubMed and Scopus. The literature search yielded 3,022 articles from these databases. Four criteria were established for study inclusion: i) studies involving Trichoderma spp.; ii) studies using food crops as the subject; iii) studies conducted in Asia; and iv) studies evaluating at least one defense enzyme activity. India has conducted the most research on this topic, with a total of 26 studies. Across 43 reviewed articles, 100 isolates were identified. The most frequently used Trichoderma species was T. harzianum, and the most common inoculation method was seed treatment, reported in 25 articles. Additionally, 50% of the articles conducted their studies in controlled environments. Trichoderma spp., known for enhancing plant resistance, also have the ability to increase certain physiological aspects of plants, such as defense enzyme activity. More research on changes in plant enzymes due to Trichoderma application is recommended, especially in field conditions, to assess its effectiveness in practical, real-world settings.

Abstract

The control of Colletotrichum gloeosporioides, the causal agent of anthracnose in chili, is typically achieved through synthetic fungicides, which pose risks to both the environment and consumers. As a safer alternative, microbial-derived biopesticides offer an environmentally friendly solution. This study aimed to evaluate the potential of secondary metabolites produced by Trichoderma viride T1sk, extracted using organic solvents with different polarities (ethyl acetate and butanol), to inhibit the growth of C. gloeosporioides in vitro. A Completely Randomized Design (CRD) was used, comprising three treatments with six replications, each consisting of two petri dish units. The treatments included: (A) ethyl acetate extract, (B) butanol extract, and (C) a control. The media poisoning method was employed to assess the antifungal activity of the extracts. Key parameters observed were colony area, conidial count, conidial germination rate, and propagule density of C. gloeosporioides. The results demonstrated that both ethyl acetate and butanol effectively extracted antifungal secondary metabolites from T. viride T1sk. In general, these metabolites significantly suppressed the growth of C. gloeosporioides. Among the solvents tested, butanol exhibited the highest efficacy in extracting antifungal compounds and consistently achieving the strongest inhibition across all observed variables.

In this systemic review, we found at least 100 isolates of Trichoderma spp. that can increase plant resistance, as indicated by the increase of plant defense enzymes in Asia. The studies were mostly reported in India and China. Rice is the most frequently studied crop. The most frequently used is T. harzianum. Meanwhile, the defense enzymes tested are peroxidase, polyphenol oxidase, phenylalanine ammonia-lyase, chitinase, and β-1,3-glucanase. The most commonly used inoculation method is seed treatment in a controlled environment such as a greenhouse. More research on changes in plant enzymes due to Trichoderma spp. application is recommended to assess its effectiveness in practical, real-world settings, especially in field conditions.

Abstract

Rhizobacteria is a group of bacteria that colonize roots, affect growth and control plant pathogens. Based on the results of previous studies, 6 isolates have the best ability to control Ganoderma boninense in oil palm seedlings. It is important to characterize them molecularly. Molecular identifications of the selected rhizobacteria isolates were done using the 16S rRNA gene. The results showed that all isolates were identified to have similarity as 5 different species i.e Bacillus paramycoides, Microbacterium paraoxydans, B. albus, B. cereus, and Serratia marcescens based on NCBI database.

Abstract

Spodoptera frugiperda J.E. Smith, sometimes known as armyworm, is a serious pest in maize crops. This pest affects maize plants' leaves, resulting in yield losses of up to 79.9%. Entomopathogenic fungi is one alternate method for controlling the pest. Various entomopathogenic fungus can be found in nature, one of which thrives endophytically on plants, such as Trichoderma asperellum. The purpose of this study was to obtain and evaluate T. asperellum's pathogenicity in suppressing S. frugiperda eggs. This investigation used five T. asperellum isolates (A116, PC21, S2D11, SD34, and AB2B3) obtained from diverse plant tissues. S. frugiperda larvae were treated with 2 mL of a conidia suspension containing 108 conidia/mL and sterile distilled water as a control. The observation variables comprised S. frugiperda egg mortality, first-instar larvae mortality, pupae formation percentage, and imago formation percentage. The findings indicated that the endophytic fungus T. asperellum can infect S. frugiperda eggs. The mortality rate for S. frugiperda eggs ranged from 43.27 to 78.34%. The mortality rate of first instar larvae ranged between 36.94% and 60.22%. The application of T. asperellum to S. frugiperda decreased pupae and imago production by 39.78% and 37.87%, respectively. T. asperellum SD324 is the most effective isolate for infecting S. frugiperda eggs. Keywords: endophytes fungus, entomopathogenic fungus, larvae, maize, Spodoptera frugiperda

Abstract

Beauveria bassiana is one of the entomopathogenic fungi to control various kinds of insect pests. Virulence of B. bassiana against insects could be affected by ultraviolet (UV) light. The study was aimed to determine the effect of different times of UV light exposure to B. bassiana against Spodoptera litura. The study was arranged in a Completely Randomized Design (CRD) with six different times of UV light exposure (control, 0, 15, 30, 45, 60 minutes) in four replications, respectively. Those B. bassiana were inoculated on the second instar of larvae of S. litura. The parameters observed were colony growth of B. bassiana, conidial germination, larval mortality, percentage of pupae, and adults formed. The data were analyzed by analysis of variance and LSD test at the 5% significance level. The results showed that exposure of B. bassiana to UV light reduced its germination but not inhibit the growth of B.bassiana. The exposure for 45 minutes and 60 minutes increased the virulence of B. bassiana that indicated by an increase of S.litura mortality (15.0-62.5%) and shorter LT50 (6.29-10.92).

Abstract

Tungro disease is one of the obstacles to increasing national rice production. The use of resistant varieties is a component to control the virus that is environmentally friendly and easily accepted because it does not require additional costs. This study aimed to determine the resistance of nine rice varieties commonly planted by farmers against the tungro. The study was conducted in a greenhouse, and the source of the tungro virus inoculum was taken from the Lintau area of ??West Sumatra Province. The results showed that of the nine varieties tested, IR 42 was resistant to the tungro attack, seven others were classified as moderate, and one variety was classified as vulnerable. The moderate resistant varieties were Anak Daro, Cisokan, Cantik Manih, Saganggam Panuah, Junjuang, Kuriek Kusuik, and Caredek Merah. In contrast, the variety that classified as vulnerable was Batang Sungkai due to the symptoms of attack more clearly than on other varieties, the fastest of a period of symptoms appear (10.15 days), the highest disease incidence (80.62%) with a disease index of 7.65.
