Abstract

This study aims to manage the population of Spodoptera exigua pests using refuge plants in onion crops. The research employed a non-factorial randomized complete block design with 4 treatments, namenly P0 (red onion without refuge plants/ control), P1 (red onion intercropped with Marigold), P2 (red onion intercropped with Zinnia), and P3 (red onion intercropped with combination both Marigold and Zinnia), with each treatment being replicated 6 times. The study comprised 24 experimental units, with each unit containing 4 plants, resulting in a total of 96 plants. The results revealed that the highest population density occurred in treatment P0 (red onion without refuge plants/ control) with a percentage of 0.55 %, while the lowest population density was observed in treatment P3 (red onion intercropped with combination both Marigold and Zinnia) with a percentage of 2.1x10-17 %. The analysis indicated significant differences between treatments P0 and P3. The conclusion drawn from this study is that treatment P3, involving the combination of Marigold and zinnia, yielded the most effective results for managing the population of S. exigua pests in red onion cultivation. Keywords: red onion, population, refuge plants, S. exigua

Abstract

Shallots (Allium ascalonicum) are a commodity in Indonesia that has high economic value. One of the pests that often attacks and reduces shallot yields is the onion caterpillar pest S. exigua. Tobacco plants and babadotan weeds are types of plants that can be used as botanical pesticides as a method of controlling and preventing pest attacks on plants. Tobacco and babadotan plants contain secondary metabolite compounds such as alkaloids, flavonoids, saponins, terpenoids and tannins which are able to kill insect pests on shallot plants. The aim of this research is to determine the effectiveness of tobacco extract (Nicotiana tabacum L.) and Babadotan (Ageratum conyzoides L.) as control of the onion caterpillar pest Spodoptera exigua on shallots. The highest combined mortality rate was treated with T6 at 96JSP with an average of 75%,The lowest larval mortality percentage test was found in T2 with an average mortality result of 22.50%.The results of biosafety testing show that the combination of tobacco extract and babadotan extract cannot be used together. From the conclusions that have been obtained, the extracts of (Nicotiana tabacum L.) and (Ageratum conyzoides L.), both single extracts and combination extracts, are effective in controlling the pest S.exigua

Abstract

Spodoptera exigua is the main pest that attacks the onion crop. S.exigua attack can cause crop failure reaching 57%-100%. The use of natural ingredients from plants for vegetable pesticides such as papaya leaves and mahogany leaves containing secondary metabolite compounds: alkaloids, papain, saponins, tannins, terpenoids, flavonoids and steroids that can damage the feeding activity system and damage the pest growth system which eventually the pest will die. This study uses a non-factorial RAL (Completely Randomized Rack) method with 7 treatments M0= Control, M1= Papaya leaf extract 30%, M2= Papaya leaf extract 60%, M3= Mahogany leaf extract 30%, M4= Mahogany leaf extract 60%, M5 = Papaya leaf extract 15% + mahogany leaf extract 15%, M6= Papaya leaf extract 30% + mahogany leaf extract 30%. The highest mortality result is 72.50% with the treatment of 60% papaya extract vegetable pesticide and the lowest is 27.50% with the treatment of 30% mahogany extract vegetable pesticide. The initial symptoms of death of S. exigua caterpillars are characterized by larvae that are less active in moving, moving to the surface of the container, moving away from the feed, convulsing and finally dying. The mortality of S. exigua larvae at 24 JSA killed a total of 14 larvae and increased with each subsequent treatment. The results of the vegetable pesticide test on natural enemies using extracts that produce the highest percentage of mortality on S. exigua is 100%. This indicates that the extract is safe for the survival of natural enemies. Plant-based pesticides papaya leaf extract, mahogany leaves and a combination of papaya and mahogany leaves have an effect on the mortality of S. exigua caterpillars

Abstract

The excessive use of pesticides and synthetic fertilizers will result in a decrease in nutrients resulting in an impact on shallot productivity, so that shallot production in Indonesia still does not meet consumer demand. This study aims to determine the effect of dosing of vegetable pesticides and POC of goat urine on shallots. This study used a factorial Group Random Design (RAK), with 3 replicates. The first factor is the use of vegetable pesticides from mahogany seeds with 3 concentration levels, namely M0 = 0 ml/100 ml of water/plot, M1 = 30 ml/100 ml of water/plot, and M2 = 60 ml/100 ml of water/plot. The second factor is liquid organic fertilizer from goat urine with 3 concentration levels, namely K0 = 0 ml/liter of water/plot, K1 = 200 ml/liter of water/plot, and K2 = 400 ml/liter of water/plot. The variables observed were plant height, wet weight, dry weight, attack intensity, and arthropod diversity. The results of the study were taken at the age of 2,3,4,5, and 6 weeks after planting (MST). The treatment of vegetable pesticides and POC of goat urine did not produce an interaction on the observed variables of plant height, wet weight, and dry weight. The results showed that the treatment of vegetable pesticides with the highest concentration at M2 resulted in a plant height of 32.60 cm, a wet weight of 35.14 grams and a dry weight of 27.11 grams. Meanwhile, the treatment of goat urine liquid organic fertilizer was the highest, resulting in a plant height of 32.73 cm in the K2 treatment. For wet weight, and dry weight, the highest treatment was in K1 with a wet weight yield of 36.92 grams, and dry weight of 29.14 grams. Regarding the intensity of pest attacks, the results of the study showed that in the first week no attacks were found. However, in weeks 2 to 6 attacks began to appear, with the highest intensity of 0.19 in the M0 treatment. The analysis of Arthropod diversity showed an index of 1.8. which indicates the level of species diversity that is currently in the research field. Overall, this study shows an increase in the growth and production of shallot plants.

Abstract

Spodoptera exigua is a major pest in onion cultivation. S.exigua larvae have a rapid spread and can cause yield losses of up to 20-100% if not controlled. Soursop leaf extract and betel leaf pesticides can cause mortality in S.exigua pests. This is due to secondary metabolites found in soursop leaf extract and betel leaf such as acetogenin, alkaloids, flavonoids, terpenoids, steroids, saponins and tannins. The purpose of this study was to determine the effectiveness of soursop leaf extract and betel leaf and the combination of both in controlling S.exigua pests. This study used a non-factorial Complete Randomized Design method with 7 treatments, namely P0 = Control, P1 = 30% soursop leaf extract, P2 = 60% soursop leaf extract, P3 = 30% betel leaf extract, P4 = 60% betel leaf extract, P5 = 15% soursop leaf extract + 15% betel leaf extract, P6 = 30% soursop leaf extract + 30% betel leaf extract. The results showed that the P2 treatment had the highest mortality rate with 67.50% mortality and the P3 treatment had the lowest mortality rate of 25.00%. Symptoms of attack show that the larvae are initially actively eating and then begin to stay away from feed, the larvae then show a change in color to brown and slowly remain still and die. The duration of pest mortality showed the fastest mortality occurred in 24 hours with the death of 20 larvae, larval mortality continued to increase with each observation. Testing on natural enemies showed results that the use of soursop leaf extract did not show any death
