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

Spodoptera exigua is the primary pest attacking shallot plants from the vegetative to the generative phase. Yield loss caused by S. exigua attack can reach 57%. Rhizobacteria have been known to be used as biocontrol agents for controlling insect pests. The research objectives were to determine and compare the effectiveness of Yuyaos and BPTPH rhizobacteria formula (Bacillus sp.) in suppressing the attack of S. exigua on shallot-growing areas. The study used a completely randomized design (CRD) of 3 treatments and five replications. The treatment consisted of shallot seedlings treated with two types of rhizobacteria (Yuyaos and BPTPH) and water (without rhizobacteria) as control before planting. Beneficial effects of the rhizobacteria on shallot plants were observed in the following variables, including the development of the S. exigua population, damage level of S. exigua, and shallot growth. The results showed that introducing Yuyaos rhizobacteria (RZ2.1AG1, Bacillus thuringiensis), which originated from the rhizosphere of the chili plant, was the best way to protect shallot plants from S.exigua. Effectively reduced the population of S.exigua (78.90%), leaf damage (62.12%), and damage intensity (38.88%). On the other hand, Yuyaos was also influential in increasing tuber growth (11.11%), plant height (43.29%), number of leaves (58.33%), and number of tillers (22.22%).

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, such as enhancing plant resistance using Trichoderma spp, are needed. 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. 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

Red chili pepper (Capsicum annuum) is a high-value horticultural crop in Indonesia, but its production is severely constrained by Aphis gossypii, which can cause yield losses of up to 65%. This study aimed to evaluate the biological characteristics, virulence, and lethal-sublethal effects of local isolates of Beauveria bassiana and Metarhizium anisopliae against A. gossypii. Fungal viability and growth were assessed through spore germination and radial growth assays, while pathogenicity was evaluated using four conidial concentrations (10⁴–10¹⁰ conidia mL⁻¹). Aphid mortality, lethal concentration (LC), lethal time (LT), and reproductive performance were recorded, and the data were analyzed using factorial and probit analyses. The results showed that both fungi exhibited high spore viability (>96%) and stable mycelial growth rates (3.71–3.74 mm day⁻¹). Aphid mortality increased significantly with increasing conidial concentration, reaching 100% at 10¹⁰ conidia mL⁻¹, whereas mortality at 10⁴ conidia mL⁻¹ ranged from 26.67% to 40.00%. Probit analysis revealed comparable virulence, with LC₉₅ values of 8.09 for M. anisopliae and 8.29 for B. bassiana. Lethal time analysis showed a concentration-dependent killing pattern, with B. bassiana acting more rapidly at lower concentrations (10⁴–10⁶ conidia mL⁻¹) and M. anisopliae exhibiting shorter LT₅₀ values at higher concentrations (10⁸–10¹⁰ conidia mL⁻¹). In addition to lethal effects, both fungi significantly suppressed aphid reproduction, particularly at higher conidial concentrations. These findings demonstrate that B. bassiana and M. anisopliae possess strong and complementary bioefficacy against A. gossypii, supporting their potential application in integrated pest management programs.

Abstract

Jorong Parit Dalam Nagari Taeh Baruah, Payakumbuh District, Limapuluh Kota Regency is one of the villages that has various problems such as drought, high number of idle lands and remote access. The main crop planted during the rainy season is lowland rice, but most of the land becomes idle land during the dry season. In terms of fertilization, farmers in this location still use artificial fertilizers (chemical fertilizers) and in terms of pest and disease control they still use chemical pesticides. The solutions that can be offered are planting chili plants which are more resistant to drought, processing agricultural waste into compost as an alternative to reduce dependence on the use of chemical fertilizers, use of Trichoderma and vegetable pesticides as agents for controlling pests and diseases, and processing chili production to increase value. selling, competitiveness and community income. The purpose of this farmer group empowerment activity is to increase public knowledge about the use of Trichoderma which can increase the growth of chili plants, and can also be used as a biological agent to control pests and diseases that often attack chili plants when cultivated. The method used in this activity is socialization and counseling, structured training and direct practice in the field of Trichoderma's influence on the growth and production of chili plants. The results obtained from this activity are that the community can recognize that there are alternative controls that are more environmentally friendly than the use of synthetic pesticides. The public can also gain new understanding regarding the increased growth and yield of chili plants by utilizing the Trichoderma biological agent. So that in the end it can reduce dependence on synthetic pesticides obtained from outside. Therefore, the environment and the balance of the ecosystem in the Nagari Taeh Baruh area are maintained. The conclusion of this activity is that plant growth applied using Trichoderma spp is higher than plants that are not treated with Trichoderma spp (control). The use of Trichoderma spp is highly recommended because besides being easy to obtain, it also provides positive values for plant growth and is good for environmental technology around cultivated plants.

Abstract

The Tunas Harapan Women Farmers Group, Limau Manis Village, Pauh District, Padang City is one of the farmer groups that has various problems such as drought, high amount of unused land and arid land. The main crop planted during the rainy season is lowland rice, but most of the land becomes idle land during the dry season. Another problem that is often faced during the implementation of cultivation is the problem of soil quality, the lack of organic matter in the soil can also be the cause of degradation which has an impact on decreasing the productivity of rice plants. In terms of fertilization, farmers in this location still use artificial fertilizers (chemical fertilizers), where the use of chemical fertilizers can also reduce the quality of agricultural food so that it is not safe for consumption. The purpose of this activity is to increase public knowledge that corncob waste and cocoa waste that are widely available in the surrounding environment can be used as compost material. The method used is the method of socialization, counseling and discussion as well as demonstrations in the form of the practice of making rhizocompost directly in the field with farmer groups and the surrounding community. The results of this activity obtained rhizocompost made from corn cobs waste and cocoa waste. The conclusion that can be drawn from this activity is the increasing understanding of the community, especially the Farmers Group (KWT Tunas Harapan) about the benefits of corncob waste and cocoa waste that can be used as the main ingredients for making compost.

Abstract

Fusarium wilt, caused by the fungus Fusarium oxysporum, is a significant disease that severely reduces the productivity of chili plants. This study investigated the potential of Trichoderma asperellum’s liquid culture as a biological control agent to control this disease and induce plant defense enzymes. Our findings demonstrated that applying the liquid culture of T. asperellum can significantly suppress disease development. Several treatments (A, D, E, and G) proved to be the most effective, showing the lowest disease severity and incidence. Furthermore, these treatments successfully increased the activity of key plant defense enzymes: peroxidase in roots (0.8746 U/g) and phenylalanine ammonia-lyase (PAL) in both roots (0.1886 μmol TCA/g) and stems (0.1653 μmol TCA/g). This increase in enzyme activity suggests that T. asperellum not only directly controls the pathogen but also triggers internal resistance mechanisms within the plant. While the liquid culture did not show a significant effect on plant growth, this may be due to the natural variability of T. asperellum and to additional factors, such as pests and environmental stress, in the field. Liquid culture of T. asperellum shows potential as a bioprotectant by suppressing the pathogen and enhancing host resistance.
