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.

Abstract

Papaya leaf (Carica papaya Linnaeus) is one of the sources of botanical fungicides that is known to have an ability in inhibiting Colletotrichum gloeosporioides growth. The aim of the study was to determine the effectiveness of papaya leaves extract to suppress of C. gloeosporioides growth that caused anthracnose disease of red pepper (Capsicum annuum Linnaeus) in vitro assay. The study was done in a Completely Randomized Design (CRD) with five concentration levels of papaya leaves extract and control (1%, 2%, 3%, 4%, 5%, and control). The parameters were colony growth, colony area, wet weight, dry weight, and conidia number (per ml of suspension). The data obtained were analyzed by ANOVA and LSD tests at 5% significance level. The results showed that the application of papaya leaves extract with different concentrations could suppress the growth of C. gloeosporioides, the pathogen of anthracnose disease in chili. The higher the concentration of papaya leaves extract given, the higher its effectiveness in suppressing the growth of C. gloeosporioides. Application at the 5% concentration was the most effective inhibiting the conidia formation (82.5%), followed by inhibiting the expansion of the colony (64.04%), reducing wet weight (45.16%) and dry weight (54.16%).

Abstract

Camel groundbeetle (Ophionea nigrofasciata Schmidt-Goble 1846) or CGB is reported as one of predators of brown planthopper (Nilaparvata lugens Stal 1854) or BPH. The difference in BPH densities is assumed to affect the predation rate of the CGB. This study aimed to determine the predation rate of CGB on BPH at different densities. This experiment used a completely randomized design (CRD) consisting of six treatments and five replications. The treatment consisted of predation of one CGB at several BPH densities (5, 10, 20, 30, 40, and 50 individuals). BPH used was second-third instar of nymphs, and the CGB used was female. The results showed that the predation rate of CGB increased with increasing BPH density with functional response types classified as type I (Linear). The highest predation occurred at 50 density (23.6 individuals or 47.2% of BPH provided). The difference in density of BPH did not affect the bodyweight gain of CGB and tended to decrease due to different prey-seeking behavior.

Abstract

Root-knot nematodes (Meloidogyne spp.) have been reported to be one of the primary pathogens that decreased tomato production in Indonesia. Biological control of root-knot nematodes by using parasitic fungus as like as Paecilomyces lilacinus is still limited. An effective application of parasitic fungi could be successful by managing a suitability application time. The study aimed to determine the suitability of the application time of the P.lilacinus in controlling root-knot nematodes on tomato. The study was conducted in farmers' land that was infected by root-knot nematodes. The experiment was done in a randomized block design with applying P.lilacinus isolates on 12, 8, and 4 days before planting, planting time, and 4, 8, 12 days after planting. All treatments were repeated four times. The application of P. lilacinus onto tomato root at planting time was better at suppressing the development of root-knot nematode compared to applications made before or after planting. P. lilacinus was able to suppress the number of root-knot (66.08%), the number of egg groups (77.33%), the number of eggs (26.79%), and the number of nematodes in the soil (82.20%).

Abstract

Endophytic bacteria have several advantages, including controlling plant pathogens and increasing plant growth. As a biological control, endophytic bacteria can suppress the development of plant pathogenic fungi. This study aimed to obtain endophytic bacteria and the consortium of endophytic bacteria that can inhibit the growth of C. oryzae. The study used a Completely Randomized Design (CRD) for studying the ability of endophytic bacteria using eight isolates: Bacillus sp HI, Bacillus sp SJI, B. cereus P14, B. cereus Se07, Serratia marcescens strain JB1E2, S. marces-cens strain JB3, S. marcescens strain ULG1E2 and S. marcescens strain ULG1E4, with three replications. For Studying the ability of endophytic bacteria consortium using six endophytic bacteria consortia and control with three replications. Observations were made on the inhibition growth of C. oryzae. The results showed that all endophytic bacteria and the endophytic bacteria consortium could inhibit C. oryzae, with inhibition of 58.50% – 75.00% and 38.00% – 77.00%. Endophytic bacteria which can significantly suppress the growth of C. oryzae were B. cereus Se07, Bacillus sp HI and Bacillus sp SJI with inhibition of 75.00%, 70.50%, and 70.00%. The endophytic bacteria consortium that had a high ability to suppress the growth of C. oryzae was the consortium of B (S. marcescens strain ULG1E4, S. marcescens strain JB1E3), D (Bacillus sp SJI, Bacillus sp HI, S. marcescenns JB1E3), and G (Bacillus sp SJI, S. marcescens strain ULG1E4), with inhibition of 77.00%, 72.33%, and 71.33%, respectively.

Abstract

Potatoes (Solanum tuberosum L.) are a strategic horticultural commodity in Indonesia, but their productivity is often hampered by attacks from plant-parasitic nematodes. This study aims to determine the effect of potato varieties on the abundance and structure of plant-parasitic nematode communities in the potato production centre of Solok Regency. Soil samples were collected randomly using the zig-zag method from red and white potato fields at several locations with different elevations. Nematodes were extracted using the Baermann funnel method, followed by population calculation, genus identification, and frequency of occurrence analysis. The results showed that the parasitic nematode community was dominated by the genus Meloidogyne in both varieties, with higher populations and frequency of occurrence in red potato varieties. White potato varieties showed lower total nematode populations with more diverse community structures. These differences indicate the influence of variety on the development of plant parasitic nematode populations. These findings emphasise the importance of variety selection as part of an integrated nematode management strategy in potato cultivation in Solok Regency.

Abstract

Whitefly (Bemisia tabaci) is a major pest on tomato plants. Whiteflies not only attack plants directly but also serve as vectors for viruses that spread diseases such as geminiviruses, causing plants to turn yellow. One alternative for controlling this pest is to use entomopathogenic fungi, such as Beauveria bassiana. This study aimed to isolate a B. bassiana strain that enhances tomato plant resistance to B. tabaci. The experiment was arranged in a Completely Randomized Design (CRD) with six treatments and five replications. The treatments included five isolates of B. bassiana, namely BbWs, TD312, PA221, PD114, and PB21 plus a control. The B. bassiana concentration used was 108 conidia/mL. The fungus was applied by soaking tomato seed lots. Results showed that seed soaking with B. bassiana significantly reduced egg, nymph, and adult populations across all isolates compared to the control. Notably, PA221 and TD312 isolates showed significant nymph suppression. Five weeks after planting, the TD312 isolate resulted in the lowest populations: 20.40 eggs per plant, 7.25 nymphs per plant, and 2.30 adults per plant. Additionally, B. bassiana application affected plant morphology by increasing trichome density; plants treated with TD312 had a trichome density of 616.73 trichomes/cm², higher than the control (295.73 trichomes/cm²). Although statistically comparable to several other isolates on some parameters, TD312 consistently exhibited the lowest pest counts and the highest trichome density, indicating its potential to enhance tomato resistance to B. tabaci by suppressing pest populations and reinforcing trichome density.

Abstract

Yellow disease in eggplant caused by a virus transmitted by Bemisia tabaci has become a serious threat to the sustainability of horticultural production in Padang City. The high dependence of farmers on chemical pesticides has the potential to induce pest resistance, environmental pollution, and health risks. This activity was conducted to enhance farmers’ capacity to recognize and control insect vectors of yellow disease through the application of eco-enzymes derived from fermented local plant organic waste as an environmentally friendly alternative control strategy. The methods applied included training, field demonstrations, mentoring, and the application of eco-enzymes in treatment plots, while chemical pesticides were applied in control plots. The results indicated that farmers’ knowledge increased by 80%. However, the incidence of yellow disease in the eco-enzyme treatment was 10% higher than that in the control, with disease severity being 3.11% higher. A production difference of 1.53 kg was observed, although plants treated with eco-enzymes exhibited better overall plant health, whereas 5% plant mortality was found in the control plots. It was concluded that eco-enzymes have not yet been effective as a single technology for controlling yellow disease in eggplant under field conditions. Therefore, the implementation of integrated pest management is required through the integration of natural enemies, the conservation of refugia plants, and the control of other pests such as shoot borer.

Abstract. Nurbailis, Djamaan A, Rahma H, Liswarni Y. 2019. Potential of culture filtrate from Trichoderma spp. as biofungicide to Colletotrichum gloeosporioides causing anthracnose disease in chili. Biodiversitas 20: 2915-2920. Trichoderma spp. have the potential to be used for controlling the airborne pathogenic fungi such as C. gloeosporioides. The purpose of this study was to evaluate the antifungal activity of the culture filtrate of five isolates of Trichoderma spp. (T. harzianum, T. viride, T. koningii, Trichoderma PP2, Trichoderma PP3) against C. gloeosporoides causing anthracnose disease in chili. Culture filtrate of Trichoderma spp. was produced from single culture and dual culture techniques. The design was a Completely Randomized Design with six treatments and four replications. The treatments were culture filtrate from T. harzianum, T. viride, T. koningii, Trichoderma PP2, Trichoderma PP3, and negative control (without culture filtrate from Trichoderma spp.). Parameters observed were: the diameter of the colony, colony coverage, conidial germination, and conidial density. The results of this research showed all the culture filtrate from Trichoderma spp. produced by single and dual culture techniques can inhibit the growth of C. gloeosporioides. The culture filtrate from Trichoderma PP2 and T. koningii were the most potential in inhibiting the growth, conidial density, and conidial germination of C. gloeosporioides.
