Abstract

Background: Shallots (Allium Ascolonicum L). is a seasonal crop that is widely grown by farmers intensively. Although the demand for productivity of this crop continues to increase, domestic production is still not enough to meet market demand because shallots are a seasonal crop. The low productivity of onion plants can be influenced by various factors, one of which is Fusarium attack, which if not controlled can cause crop failure. The use of chemical pesticides to control Fusarium sp. often causes dependence and pollution, so alternative controls are needed. The purpose of this study was to determine the potential of Fobio Biopesticide against three onion varieties in increasing growth and reducing the intensity of Fusarium sp. attack.Method: The method used is RAKF with a factor of 1 consisting of three varieties of shallots (Biru Lancor, Tajuk, and Batu Ijo), factor 2 in the form of farmer treatment and concentration levels of Biopesticide Fobio 5 and 10 ml / l. Results: The results showed that treatment with a concentration of Biopesticide Fobio 5 ml / l and Blue Lancor varieties was able to increase the best results in various variables such as plant height, wet weight, dry weight, disease intensity, and incubation period. Conclusion: Based on the research that has been done, it can be concluded that Fobio Biopesticide has the capacity to increase the resistance of onion plants to moler disease. Treatment with Biopestiisda Fobio concentration of 5 ml / l in the Lancor Blue onion variety showed the best results in various variables compared to other treatments, it was shown an increase in plant height up to 5 – 6 cm, wet weight up to 2.8 g / tuber, dry weight up to 1.7 g / tuber, disease intensity up to 8% at 42 HST, and the longest incubation period up to 23 days.

Abstract

Background: Seed-borne pathogens threaten plants because they can survive in seed tissues for long periods. Efforts that can be made include treating the seeds before planting them in the field with biological agents, one of which is Trichoderma sp. It is often found in soil with high organic matter, namely peat soil. This research aims to determine the potential of Trichoderma sp. isolates. from peat soil on pathogen infection of soybean seeds and germination of soybean seeds. Method: This research used a factorial method. The first factor was sick and healthy seeds, and the second was Trichoderma sp. isolates, consisting of TP1 and TP2. The control treatment uses the active ingredient fungicide mancozeb 80%. Seed treatment was carried out by soaking the seeds in a suspension of Trichoderma sp. with a spore density of 106 for 24 hours. The seeds were then tested using the growing-on-test method in sterile soil. Results: Identifying pathogens in soybean seeds found two genera, Aspergillus sp., and Fusarium sp., in the immersion treatment on Trichoderma sp isolates. TP2 gave the best results, where the lowest infection power was 46.6% for healthy seeds and 73.3% for symptomatic seeds. In addition, treatment with isolates of Trichoderma sp. TP2 can increase the germination capacity of soybean seeds by 60.0%. However, seed treatment with Trichoderma sp. does not affect soybean plant height and root length growth. Conclusion: The two isolates of Trichoderma sp. from peat soil positively protect seeds against soybean seed pathogens, seed germination, and soybean growth.
