Abstract

Brown planthopper or BPH (Nilaparvata lugens Stal, Hemiptera: Delpachidae) is a significant pest that is a severe problem to rice plants in various places, including Bogor District, East Java Province. Resistance of several varieties of rice to BPH of Bogor Population has not been reported. One method to determine a variety's resistance is the honeydew test. This study aims to determine the resistance of several rice varieties to BPH of Bogor population. This study used six different varieties as treatments, and carried out in five replications. Those varieties were Pelita, Mapan, Situ Bagendit, Ciherang, Inpari-33, and IR-64. The observations were made on the area of honeydew spots produced by BPH after consuming sap of rice plant. This research showed that the Situ Bagendit variety was relatively resistant to BPH of Bogor population. The Mapan and Pelita varieties were quite susceptable, while Inpari-33, Ciherang, and IR-64 were moderate. The region of origin where BPH grows and the testing procedure can affect the resistance category of one variety.

Abstract

Anthracnose is an important disease in red chili caused by Colletotrichum capsici which can reduce productivity by up to 65%. Controlling using indigenous epiphytic yeasts has never been done. The study aimed to determine the ability of indigenous epiphytic yeast isolates to control C. capsici on red chili. The study was carried out at the Phytopathology Laboratory, Faculty of Agriculture, Universitas Andalas, from August 2019 - April 2020 in vitro and in vivo. The study used a completely randomized design (CRD) which consisted of 6 treatments with five different isolates (4 isolates from fruit and one from leaves) and a control. Parameters observed were macroscopic and microscopic characteristics of yeasts, C. capsici colony area, disease incubation period, and anthracnose symptoms. The results showed that the five epiphytic yeast isolates could suppress the growth of C. capsici, inhibit colony expansion between 27.09 – 59.11%, extend the incubation period for one day, and inhibit the expansion of anthracnose symptoms between 52.30 – 62.64%. Epiphytic yeast isolate KB1 derived from fruit has the highest inhibition.

Abstract

Rhinoceros beetle (Oryctes rhinoceros) is the primary pest of oil palm (Elaeis guineensis Jacq.). Applying oil palm empty fruit bunches (OPEFB) and various other organic materials to cultivated land is assumed to support the growth of rhinoceros beetles. The study aimed to determine the suitability of organic matter as a place for rhinoceros beetle larvae to live. The research was carried out experimentally using a completely randomized design (RBD) with eight treatments and four replications. The treatment was in the form of OPEFB, rice husk, sawdust, OPEFB + rice husk, OPEFB + sawdust, OPEFB + rice husk + sawdust, and OPEFB + rice husk + sawdust without composting. The results showed that the growth of rhinoceros beetle larvae tended to be best on an organic material combination of OPEFB + rice husk + sawdust without being composted. Meanwhile, rice husk is the most unsuitable organic material for developing rhinoceros beetle larvae. Applying organic matter to palm land should be composted beforehand to reduce Rhinoceros beetle infestation.

Abstract

Atrazine 500 g/l is a selective herbicide that can be applied during pre- or post-growth of corn. This study aimed to determine the effective level of dosage in controlling weeds in the corn planting area and its impact on growth and corn yields. The study was conducted at the Experimental Garden of Universitas Lampung, South Lampung, and the Weed Laboratory of the Faculty of Agriculture, Universitas Lampung, from August to November 2022. The study used a Randomized Block Design (RBD) with seven treatments and four replications. The treatment consisted of 5 herbicide doses (Atrazine 500 g/l (500, 750, 1,000, 1,250, and 1,500 g/ha), manual weeding, and control. The results showed that Atrazine 500 g/l at doses of 750 - 1,500 g/ha effectively controlled the growth of total weeds, broadleaf and grass weeds, Digitaria ciliaris, and Richardia brasiliensis. While at doses of 500–1,500 g/ha, it effectively controlled Eleusine indica, Cleome rutidosperma, and Commelina benghalensis. Those doses did not poison, and did not inhibit growth, and the yield of maize.

Abstract

The density and attack rates of Spodoptera frugiperda have been reported in various maize cultivation in Indonesia, but there has never been a report in Sijunjung District, West Sumatra. The research was conducted to study the attack level, density, and distribution of S. frugiperda in Sijunjung District. The study was carried out in March -May 2023 using a survey method in 8 sub-districts in Sijunjung District. The results showed that S. frugiperda had spread and attacked maize crops evenly in Sijunjung District, but the attack rate (26.96%) and density (0.24 individuals) were low. The highest attack was found in Nagari Guguak (88.7%). The high or low rate of attacks is influenced by differences in varieties, planting ages, and maize cultivation techniques. Meanwhile, the density is more influenced by age differences.

Abstract

Integrated Pest Management (IPM) is a pest control method that combines several control techniques by considering ecological, economic, and sociological consequences. Management efforts with IPM principles can be conducted by cultivating healthy plants and entomopathogen application. This study examined the IPM package's success for controlling fall armyworm (Spodoptera frugiperda) in maize field. This research was conducted in a farmer's maize plantation in the West Pasaman District from August to December 2021. The study used a Randomized Block Design (RBD) which consisted of three treatments and five replications. The treatments were different cultivation techniques using IPM, Non-IPM, and control. The variables observed were the population of S. frugiperda (individual/plant), attack rate (%), attack intensity (%), cob weight (g/cob), and farming cost (IDR). The results showed that the IPM and Non-IPM maize cultivation techniques had no different effect on S. frugiperda, especially survival stage, attack rate, intensity, and yield. However, this effect was higher than the control. In addition, the economic benefits of cultivation with IPM were higher than non-IPM. Therefore, this IPM package can be recommended for controlling S. frugiperda because it is also economically profitable and environmentally friendly.

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 production of rice is closely related to the presence of pests, one of which is the rice field rat (Rattus argentiventer). The development of pests that attack plants is influenced by the dynamics of climate factors, both directly and indirectly. The climate in Karawang Regency is highly suitable for the growth of R. argentiventer. In the rice - rice - intercrop cropping pattern, climate factors have strong influence on the infestation of rice field rats during the intercrop season. Meanwhile, climate factors have low influence during the rice monocrop season. Based on CLIMEX output, the altitude difference in Karawang Regency does not have a significant effect on the environment suitability for the growth and development of rice field rats, allowing them to live in any rice field in Karawang Regency. Based on climate scenarios, the suitability of the climate in Karawang Regency for the potential growth and development of rice field rats is projected to decrease in the 2070s. Increasing temperatures and decreasing rainfall cause the rice field rats to experience dry stress.
