Abstract

Spodoptera frugiperda is a polyphagous insect pest that attacks corn, sorghum, soybeans, wheat, and horticultural crops. The feeding activities of S. frugiperda larvae can lead to significant economic losses for farmers. Current efforts to control S. frugiperda still rely heavily on the use of chemical insecticides. However, the excessive or inappropriate use of chemical insecticides can lead to the survival of pests that are resistant to these treatments. Bioinsecticides are considered to have lower toxicity to both living organisms and the environment, which makes them a potentially ideal option for agricultural use. This study aims to test the toxicity both individually and in combination as well as the interaction properties of a mixture of Annona muricata and Leucaena leucocephala seed extracts in various ratios as bioinsecticides against S. frugiperda in sweet corn plants. The research methods consist of rearing S. frugiperda, extraction, bioinsecticide formulation, single and mixed toxicity tests, and the interaction properties of the mixture. The results of the study showed that the method of making nanoemulsions by homogenization showed better toxicity activity compared to the method of making nanoemulsions by inversion phase. The toxicity of nanoemulsions of mixed extracts of A. muricata and L. leucocephala seeds against S. frugiperda pests at a ratio of 1:2 was more toxic than the ratios of 2:1 and 1:1. The nature of the interaction of nanoemulsions of mixed extracts of A. muricata and L. leucocephala was more dominantly antagonistic.

Abstract

Seed storage is an important aspect of plant breeding. Aged seeds tend to lose their viability during storage, reducing their ability to grow. One effort to increase the viability of seed germination that has been stored for a long period is to provide priming treatment to the seeds before planting. The purpose of this study was to evaluate the effect of garlic oil emulsion on the germination of aged melon seed that has been stored for more than five years. The study was conducted using a factorial completely randomized design (CRD). The first factor consisted of two melon seed lines that had been stored for more than five years, namely Ougan makuwauri (V1) and Ginsen makuwauri (V2), and the second factor was the priming treatment consisting of P0 = Aquadest, P1 = 0.125% garlic oil emulsion, P2 = 0.25% garlic oil emulsion, and P3 = 0.5% garlic oil emulsion, each treatment was repeated three times with a soaking time of 20 hours. There is an interaction between the line and priming treatment that significantly affects the variable of cotyledon opening on the fifth day and hypocotyl length. Meanwhile, the single priming treatment has a significant effect on the observation variable of cotyledon opening on the third day and has a very significant effect on the variable of root length of germinated melon seeds.

Abstract

Urban farming by cultivating microgreens is an alternative for fulfilling food security. Microgreen is a technique for cultivating vegetables in urban areas, with a harvest time of 7-14 days after sowing. Increased cowpea microgreen production is influenced by growing light and natural phytohormones. This research aimed to determine the role of grow light distance and natural phytohormones in increasing production and chlorophyll content in cowpea microgreens. This research used a Randomized Block Design (split-plot) consisting of 2 factors. The 1st factor, A1= 20 cm, A2= 40 cm and A3= 60 while the 2nd factor, B0 = Aquades, B1 = 50% Aquades + 50% Coconut Water, B2= 50% Aquades + 50% Onion Extract , B3 = Aquades 50% + Coconut Water 25% + Onion Extract 25%. The research results showed that the treatment of 50% distilled water + 25% coconut water + 25% shallot extract at a grow light distance of 60 cm produced the highest value for the plant height parameter, namely 16.70 cm. The highest chlorophyll content was in the combination of 50% distilled water + 50% coconut water at a distance of 20 cm, namely 52.97 mg/g. The 60 cm grow light distance treatment produced the highest plant height, namely 18.88 cm, the heaviest wet weight parameter using a 40 cm grow light distance, namely 1.43 grams and a 20 cm grow light distance produced a high chlorophyll content, namely 38.40 mg/g. The aquadest treatment produced the highest plant height, namely 14.33 cm, while the optimal number of leaves and fresh weight used the 50% aquades + 25% coconut water + 25% shallot extract treatment, namely 5 pieces and 1.38 g and the 50% aquades + coconut water treatment. 50% produces a high chlorophyll content of 24.87 mg/g.

Agronomic and morphological characteristics of two rice genotypes plant in open land and under two years of sengon (Paraserianthes falcataria). Biodiversitas 24: 4927-4933. The increase in population is the biggest challenge for the agricultural sector in providing food needs. The main problem in increasing food production in Indonesia is the limited agricultural land. There is a need to explore alternative land options to address this issue and enhance production capacity, specifically for rice at the national level. One of the potential solutions is to use land currently occupied by plantation crops and forests that can be managed through agroforestry. Sengon (Paraserianthes falcataria (L) I.C.Nielsen) is a forestry plant that offers a comparative advantage for investigation in agroforestry systems due to its relatively open canopy cover and classification as a legume. Therefore, this research aimed to determine the response of the morphological and agronomic characters of two rice genotypes planted in open land under 2-year-old sengon stands. The experiment was conducted from October 2017 to March 2018 in the Sengon community forest of Cikarawang, Bogor, with coordinates 06° 33.061' S and 106° 43.987' E. The results showed that two rice genotypes grown under one-year-old sengon stands experienced decreased productive tillers, plant height, stem strength, and the number and weight of grains per panicle. The IR 64 genotype decreased by 40.65% in grain weight per panicle, while the Situ Patenggang genotype experienced a 56.21% decrease.

Abstract. Nuryanti NSP, Budiarti L, Dulbari, Sutrisno H, Sudrajat D, Yuriansyah, Priyadi, Rahmadi R, Rochman F, Sari EY, Maharani JS. 2023. Activity of nanoemulsion botanical insecticides from Myristica fragrans and Jatropha curcas essential oil against Sitophilus zeamais. Biodiversitas 24: 5610-5617. Maize weevils also known as Sitophilus zeamais, are primary pests that decrease in the quality and quantity of grain products. This study aimed to examine the impact of nanoemulsion formulas of Myristica fragrans and Jatropha curcas essential oils on S. zeamais adults. The investigation focused on the toxicity, ability to inhibit population growth, intensity of damage caused, and effect on seed weight loss. The essential oils were extracted using the distillation method, and the toxicity was tested through contact, fumigant, and seed dressing. A probit program was used to analyze the toxicity level (LC50 and LC95). The results showed that M. fragrans essential oil had the highest toxicity in contact treatment and the lowest when applied via fumigation. Furthermore, this method shows an LC50 value for the contact method of 0.53% and fumigation of 1.01%, while the LC95 value is 4.38% and 10.60% respectively. Based on the LC95 botanical insecticide from J. curcas, all three methods were toxic to S. zeamais adults, with contact being the highest, followed by seed dressing, and fumigant, at 5.23, 6.44, and 19.94%, respectively. The botanical insecticides derived from M. fragrans essential oil through contact provided the best inhibitory activity on population development, intensity of damage, and seed weight loss, with values of 18.00, 16.81, and 13.96%. Plant-based pesticides not only cause pest mortality but also maintain seed quality by reducing weight loss, intensity of pest attacks, and inhibiting the development of pest populations in storage.
