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.

Abstract

Background: Rice (Oryza sativa) is the world's second most important food crop after wheat. In Indonesia, more than 90% of the population consumes rice, and there is a very high level of dependence, so rice has essential value for the Indonesian population. However, this has not been accompanied by the availability of healthy seeds because many pathogenic fungi are carried by rice seeds, such as Rhizopus sp., Mucor sp., Aspergillus sp., Fusarium sp., Curvularia sp. Seed treatment using synthetic fungicides is an effort to control pathogenic fungi on seeds, but it hurts seeds, humans, and the environment. A safe control alternative is using biological agents, namely the fungus Trichoderma sp. isolated from peatlands and has an antibiosis mechanism. The research aimed to test the potential of the fungus Trichoderma sp. from peat soil as a biological control agent for pathogenic fungi carried by rice seeds (Oryza sativa). Methods: The test uses the incubation method on PDA media and the growing test method on sterile soil media. The research used a completely randomized design with a factor of 2 isolates of Trichoderma sp. and eight replications and data analysis using BNJ5%. Results: isolation results obtained two isolates of Trichoderma sp. (P1 and P2), two isolates of Trichoderma sp. (P1 and P2) were able to suppress the level of pathogenic fungal infections carried by rice seeds in the incubation method using PDA media and the growing on test method, 3.75%, two isolates of Trichoderma sp. able to increase the germination capacity of rice seeds by P1 (12.50%) and P2 (31.25%) respectively. Conclusions: Two isolates of Trichoderma sp. (P1 and P2) could suppress the level of pathogenic fungal infections carried by rice seeds in the incubation method using PDA media and in the growing on test method. Apart from that, two isolates of Trichoderma sp.

Abstract

Background: Seed is a planting material that must have high viability and quality, including being free from pathogens. One of the obstacles in the supply of quality maize seeds is seed-borne fungal pathogen which can affect the quality of maize seeds and cause plant disease. Endophytic bacteria Bacillus sp. has been widely studied to be able to produce secondary metabolites as antifungals. This study aimed to determine the exact concentration of secondary metabolites of endophytic bacteria Bacillus sp. to decrease the infections of seed-borne pathogens fungal on maize seeds using the blotter test method. Methods: This study used a completely randomized design with four concentration levels (10%, 15%, 20%, 25%) and two strain codes of endophytic bacteria Bacillus sp. (Bth-31a and Bth-22). Results: The result of identifying seed-borne fungal pathogen on maize seed included Fusarium sp., Aspergillus flavus, Aspergillus niger, and Rhizopus sp. The Bth-22 treatment with a concentration of 25% could decrease the infection of seed-borne fungal pathogen and had the highest percentage until 50% compared to the control. While the lowest percentage to decrease the infections of seed-borne fungal pathogen occurred in the Bth-31a treatment with a concentration of 10%, which was 32.1% compared to the control. Conclusions: All seed treatments that used secondary metabolites of Bacillus sp. able to decrease the infections of seed-borne fungal pathogen on maize seed compared to the control. In addition, the treatment of secondary metabolites Bacillus sp. is able to increase the germination of maize seeds.
