Abstract

Damping off caused by Rhizoctonia solani is an important soil-borne disease in tomato nursery. In addition to their role as organic fertilizer, compost and vermicompost are able to suppress plant diseases. Compos and vermicompost can be applied directly or in the form of their soaking water or teas. This study evaluated the abilities of compost, vermicompost, compost tea and vermicompost tea to inhibit R. solani in vitro and suppress damping off disease in tomato seedlings. The in vitro experiment used completely randomized design, while the experiment in tomato seedlings used randomized complete block design. The in vitro experiment examined nonsterile and sterile suspension or teas of compost and vermicompost. The treatments in tomato seedling experiment were compost or vermicompost applied in the growth media (25% v/v), compost or vermicompost tea applied to the tomato seedlings every 3 days or 7 days, and untreated check. The results showed that in the agar media containing suspension of compost or vermicompost nonsterile was dominated by Trichoderma spp. colonies and therefore the growth of R. solani was inhibited by 58.5-60.0%. The sterile preparation of compost, vermicompost and their teas did not inhibit the pathogen. Compost and vermicompost incorporated to the growth media suppressed damping off disease caused by R. solani by 54.2-66.7%. The abilities of compost and vermicompost to suppress the disease and support plant growth were better than their teas. Drenching the seedlings with compost tea every 3 or 7 days suppress damping off disease by 31.0-41.7%. However, vermicompost tea showed disease suppression (27.6-37.1%) only if it was applied every 3 days.

Abstract

Using of synthetic insecticides to control the C. pavonana pest could have negative impacts. As an alternative control, using plant extracts is relatively safer in controlling these pests. This research aims to study the bioactivity flower of kipahit T. diversifolia extract on mortality and feeding behavior of C. pavonana larvae. Extraction was carried out using the maceration method using methanol. Bioassay for insecticidal activity was carried out using the residual method on the leaves against larvae II. Feeding on treated leaves was carried out for 48 hours. the antifeedant assayed for 24 hours of exposure to instar III. The concentration - mortality relationship was analyzed using probit analysis. Data on development time are expressed as the average value ± standard deviation. The results showed that the activity of kipahit flower extract had an LC50 of 0.51% and an LC95 of 3.86%. These extract with choicw method at the sub lethal dose tested inhibit the feeding activity by 24.90%, 53.96%, 76.34% respectively, while the no choice method inhibits feeding activity by 27.20%, 59.69% 86.40%, respectively.

Abstract

Planococcus minor is one of the pests prohibited from entering several destination countries during the mangosteen export process. Control of P. minor can be achieved by using patchouli and eucalyptus essential oils. The objective of this research is to determine the effects of patchouli and eucalyptus essential oils on the mortality of P. minor, with the aim of developing control measures to prevent mangosteen export failures. This study was conducted at the Class 1 Agricultural Quarantine Station in Bandung from May to December 2023. The method used is the experimental method with a Randomized Complete Block Design. Contact and neurophysiological tests were conducted with 13 treatments, including distilled water control, distilled water + tween 80 control, synthetic pesticide with abamectin 0.005%, patchouli essential oil at concentrations of 0.13%, 0.18%, 0.24%, 0.32%, 0.43%, and eucalyptus essential oil at concentrations of 0.22%, 0.29%, 0.39%, 0.51%, 0.68%, each repeated three times. The research results indicate that mortality of P. minor caused by 0.43% concentration of patchouli essential oil did not significantly differ from abamectin, with a rate of 96.67%. The LC50 values for patchouli and eucalyptus essential oils were 0.19% and 0.42%, respectively. The LT50 value of eucalyptus essential oil is lower when compared to the LT50 value of patchouli essential oil. The LT50 value of eucalyptus essential oil at the highest concentration of 0.68% was 49.94 JSP. Patchouli essential oil at concentrations of 0.43% and 0.32% had different LT50 values of 37.27 and 50.73 JSP. Furthermore, based on morphological observations that eucalyptus and patchouli essential oils affect the morphology of mealybugs.

Abstract

Spodoptera frugiperda is a pest that is capable of migrating over a wide range. Currently, the S. frugiperda attack can be said to be comprehensive in almost all regions of Indonesia. The level of adaptability of S. frugiperda to the suitability of the agroecosystem needs to be reviewed further in order to predict the potential for S. frugiperda attacks in the future. This research aims to test the suitability of temperature for the biological activity of  S. frugiperda. The treatments tested in this study included temperatures (A) 34.0±2.2 oC, (B) 27.0±4.1 oC, and (C) 19.0±1.3 oC. Each treatment used 5 larvaes 2nd instar and was repeated 6 times so that the number of test insects used was 120. The parameters observed in this study included growth, development, feeding activity and mortality rate of the test insects. The data obtained was then analyzed using ANOVA and tested further with DMRT at an error level of 5%. Differences in rearing temperature can affect growth, development, feed consumption and larval mortality. Temperature (B) 27±4.1 ℃ is the most suitable temperature for S. frugiperda. Temperatures (A) 34.0±2.2 ℃ and (C) 19.0±1.3 ℃ are less suitable temperatures, but S. frugiperda can still carry out its life cycle. This research can provide an overview to anticipate S. frugiperda attacks that may occur due to global warming in the future.

Abstract

Fusarium oxysporum f.sp. cepae (FOCe) is a pathogenic fungus causing moler disease in shallots. One method of controlling this disease is by using endophytic bacteria. Endophytic bacteria are bacteria that live in plant tissues without causing disease symptoms. This research aims to obtain the most effective endophytic bacteria in inhibiting the growth of the pathogenic fungus FOCe. The study employs a Completely Randomized Design (CRD) consisting of 8 treatments with 3 replications each. The treatments include Bacillus sp. HI, Bacillus sp. SJI, Bacillus cereus P14, Bacillus cereus Se07, Bacillus subtilis, Serratia marcescens JB1E3, Serratia marcescens ULG1E4, and control. Tests conducted include the antibiosis test of endophytic bacterial cells using the dual culture method and the secondary metabolite test using media poisoning method. The observed parameters include inhibition zone, effectiveness of secondary metabolites, fresh weight, and dry weight of the FOCe fungus. All endophytic bacteria were capable of inhibiting the growth of FOCe. The most effective endophytic bacteria in inhibiting the growth of FOCe were found to be Serratia marcescens ULG1E4 and Serratia marcescens JB1E3. In the antibiosis test of endophytic bacterial cells, Serratia marcescens ULG1E4 exhibited an inhibition zone of 64.44%, while Serratia marcescens JB1E3 showed an inhibition zone of 61.11%. In the secondary metabolite compound test, the effectiveness values for Serratia marcescens ULG1E4 and Serratia marcescens JB1E3 were 95.31% and 95.03%, respectively.

Abstract

Weeds are plants whose presence is unwanted because they interfere with and reduce the yield of cultivated plants. One of the plantation crops with high economic value is coconut. Coconut is a commodity that can make a major contribution to the economy in Indonesia. The presence of weeds in coconut plantations will reduce yields. This study aims to determine the diversity and dominance of weed species that grow in the coconut plantation area in Tial Village, Central Maluku Regency. This study uses the "weed survey" method to collect data by direct observation in the field. In conducting vegetation analysis, the quadratic method was used with a sample plot measuring 1 m x 1 m. For sampling in the coconut planting area in Tial Country, 6 plant samples were taken at each plant stage to obtain 12 plant samples and repeated 3 times to obtain 36 observation samples. Observations of weeds in Tial Village showed that in the immature coconut planting area, there were 11 broadleaf weed species from 10 broadleaf weed families, 3 pakisan weed species from 2 pakisan weed families and 1 grassy weed species from the Poaceae and 1 type of tekian weed from the Cypeaceae tribe, as well as from observations of weeds in Tial Village, it shows that in the coconut plantation area at the productive stage, there are 13 types of broadleaf weeds from 11 broadleaf weed families, 2 types of pakisan weeds from 1 pakisan weed tribe and 1 type of grass weed from the Poaceae tribe and 1 type of tekian weed from the Cypeaceae tribe. Based on the total dominant value Summed Domination Ratio (SDR) the immature plant had the highest value, Thuja occidentalis 26.78 percent from the Convovulaceae tribe. In the coconut planting area the mature stage of the plant having the highest SDR value was Stelaria holasta.L 29.21 percent from the Caryophylaceae.

Abstract

Coffee is one of the export commodities that has produced gross domestic product up to 16.15% of the agricultural sector. However, pesticide residues in agricultural products remain a barrier in the context of exports and agricultural product safety. The study aims to analyze the pesticide residue content in coffee produced by farmers at the Manglayang Mountain Community Coffee Plantation (CCP) compared to the maximum residue limit. The method used in this research is explorative descriptive by collecting samples from the Giri Senang Forest Community, Legok Nyenang-Giri Mekar Village, Cilengkrang District, Bandung Regency, and analyzed with the method EN 15662:2018. A kilogram of coffee is washed and dried for two days, then separated from the skin of the coffee and the green bean. The green bean are then extracted by QuEChERS, by adding 1% acetic acid in acetonitril and the extract is cleansed using high SPE  dispersive. LC-ESI-MS/MS is operated in MRM mode, and validated according to the SANTE 12682/2019 requirements. The results of the research showed that the coffee from was not detected containing residues of pesticides from the organophosphate and carbamate groups. Thus, the coffee products from Manglayang Mountain CCP are considered safe to be consumed, and can be exported abroad.

Abstract

The development of cocoa in Indonesia was followed by an increase in cocoa waste in the form of fruit skins as much as 75% of fruit skins. The purpose of this study was to determine the formulation of fungi (Trichoderma harzianum and Pleurotus ostreatus)and methods of composting cocoa fruit skin waste as well as analysis of the quality of the compost produced.  The research was conducted at Bontomanai village, Bungayya sub-district, and Gowa district which all have composting facilities on February to June 2023 . The quality testing of compost and counting the amount of Phytophtora palmivora spores in cocoa pod husk compost was carried out in the Plant Disease Laboratory, Department of Plant Pest and Disease, Faculty of Agriculture, Hasanuddin University. This study consisted of three activities, there were producing compost, checking the quality and maturity of the compost, and measuring the amount of P. palmivora spores in the cocoa pod husk compost. This study included six treatments, notably P0: without Bioactivator, open pile, P1: T. harzianum, open pile, P2: P. ostreatus, open pile, P3: T. harzianum + P. ostreatus, open pile, P4: T. harzianum + P. ostreatus, open pile P4: without Bioactivator, close pile, P5: T. harzianum, close pile, P6: P. ostreatus, close pile, P7: T. harzianum + P. ostreatus close pile. Based on the compost maturity test and nutritional content analysis of cocoa waste, it can be seen that the most effective treatment in composting cocoa pod shells was the T. harzianum + P. ostreatus in open pile treatment, the highest levels of P2O5 and K2O but lowest levels of C/N.  Composting process had also reduced the amount of P. palmivora in cocoa pod husk waste.
