“…Observation of shallot twisted disease. Twisted disease on shallot showed typical symptoms with twisted or curved leaves due to disturbances at the roots or base, estimated to rot extensively and consequently hinder the function (Supyani et al, 2021). The twisted disease on shallot in Bantul coastal area showed in Figure 2.…”

Shallot (Allium cepa var. aggregatum L.) is an important commodity in horticulture and Indonesian foods. In Bantul Regency, Yogyakarta, Indonesia, shallot twisted diseases caused by Fusarium spp. significantly reduced yield quality and quantity. Supportive condition for plant-pathogen interaction needed for twisted disease development. This research aimed to measure the twisted disease incidence and observe the cultivation practice applied by shallot farmers in the Bantul coastal area as environmental aspects of the twisted disease to be a pre-study for further research on metagenomic analysis. This research had conducted in three sub-villages with different agroecosystems in the coastal area: Sono, Samiran, and Depok. Data were collected in shallot cultivation period in dry and rainy seasons from three farmers of each area. The higher disease incidence in the rainy season occurred in the Samiran sub-village at 33.97%, while in the dry season, disease incidence occurred in the Depok sub-village at 20.14%. Sono sub-village had the lowest disease incidence in rainy and dry seasons at 12.44% and 0%. Farmer cultivation practice may drive disease incidence due to environmental factors such as shallot variety, spacing between plants, fertilizer, and fungicides. Hence, further study is needed to understand plant-pathogen interaction with metagenomics through samples from 2 and 6 WAP in rainy seasons.

“…The most important pathogen today is Fusarium oxysporum f.sp. cepae (FOCe) causing basal rot [3], [4] that in Indonesia is called Moler disease due to the early symptoms of twisted leaves which the Javanese call moler. In the field, the intensity of moler can reach more than 60% with yield losses up to 40% [4], [5].…”

Moler caused by Fusarium oxysporum f.sp.cepae is a seed-borne disease, so the disease intensity in the field is depend on the amount of initial inoculum in the infected bulbs as seeds. Therefore, the detection of seed-borne pathogens is important to determine the potential of their transmission. The aim of this research was to evaluate the sensitivity of the bulb tissue of shallot based on the pathogen Infection Index by incubation method on agar media to detect the presence of F. oxysporum f.sp. cepae. The experiment was conducted using a completely randomized design with five replications and three varieties of shallots (Thailand, Bima, and Bauji). Each treatment unit was placed in a Petri’s dish with a diameter of 20 cm, containing 40 mL PDA on which 16 pieces of the tip, middle, and base of the bulb tissues were placed, which were incubated for 7 days. Pathogen Infection Index is a parameter that was observed macroscopically and microscopically. The results showed that the base of the bulbs tissue section of the three varieties tested showed higher sensitivity than the other part to detect the presence of F. oxysporum f.sp. cepae in shallot. It indicates that the basal bulb is the major infection side of the pathogen.

The main obstacle to garlic cultivation is the attack of Fusarium oxypsorum f. sp. cepae (FOCe) causes basal rot. Bacillus and Trichoderma are popular antagonist microorganisms that can act as biological control agents (BCA). This paper would like to report on the effectiveness and compatibility of Bacillus sp. and Trichoderma sp. as a biological control of basal rot of garlic based on laboratory and Greenhouse tests. The results of in vitro studies show that Bacillus and Trichoderma are potential antagonist agents through antibiosis and even Trichoderma through competition. Meanwhile, in vivo, the two biological control agents were not effective in reducing wilting intensity but effective in reducing basal rot intensity and increasing disease tolerance. Increasing disease tolerance is showed by the yield that is higher significantly than those control with no BCA. Bacillus sp. and Trichoderma sp. have been shown to be incompatible BCA based on both in vitro and in vivo tests, which are indicated by the effectiveness of the combination application being less effective than alone.
