“…It has also been confirmed by (Ramadhina et al, 2013) and (Akhtar & Javaid, 2018). According to (Deden & Umiyati, 2017), Trichoderma could limit Fusarium oxysporum f. sp. cepae growth by up to 95.9 percent in vitro.…”

Fusarium wilt disease/moler is a concern in onion cultivation. Many farmers apply chemical pesticides such as azoxystrobin and difenoconazole to control the diseases. Both of these chemical pesticides are currently exhibiting a decline in effectiveness, prompting farmers to increase the dosage and frequency of application. Recommendations for biological control, including Trichoderma spp.. This study aimed to determine the influence of application time of of Trichoderma spp. in various media types on the incidence of moler disease and shallot growth and yield. This study was conducted in Tabalong district, South Kalimantan, from February to June 2019 using a completely randomized design (CRD) factorial comprising two nested designs. The first factor was the type of media in which Trichoderma spp.. was applied, namely solid and liquid. The second factor was the application time of Trichoderma spp.. Level 1 was the application of Fusarium sp. seven days before planting and Trichoderma spp.. seven days after planting. Level 2 included the application of Trichoderma spp.. seven days before planting and Fusarium sp. simultaneously during planting. Level 3 involved the administration of Trichoderma spp.. concurrently with planting and Fusarium sp. seven days later. This investigation used one positive control (without treatment) and one negative control (shallots inoculated with Fusarium). Each experimental unit was consisted of ten plants and replicated three times. The parameters observed were the incubation period of Fusarium sp., disease incidence, number of leaves, plant height, number of cloves, and average clove weight. The study found that the application time of Trichoderma on various types of media affected the incidence of Fusarium disease, the number of leaves, and the number of shallot cloves.When compared to liquid media, the application of solid media resulted in a reduced incidence of Fusarium disease and a greater frequency of flares. The application time on solid media gave a low response to moles. As for liquid media, the lowest incidence of moler disease occurred at the seven days before planting.

“…Batuijo performed as moderately resistant, while the cultivars Bauji from Magetan and Nganjuk were susceptible to FOCe. The productivity of shallots was affected by the disease severity and the variety of shallot (Wiyatiningsih et al, 2009;Prakoso et al, 2016;Deden and Umiyati, 2017;Edy, 2019). The reports, however, did not discuss about the yield losses by the disease.…”

Basal plate rot or moler caused by <em>Fusarium oxysporum</em> f. sp. <em>cepae</em> (FOCe) is the most important disease of shallot. However, the information of crop losses attributed to the pathogen is still limited, especially related to resistance of shallot. This paper discusses the correlation between disease severity and resistance of some shallot varieties to yield losses. The experiment was arranged by Completely Randomized Design (CRD) with six varieties of shallot as treatments, each of which consisted of 20 shallots, with three times of replications. The independent variables were the disease severity of twisting leaf and rotting of shallot bulb. The association of disease severity versus yield losses in different varieties was based on the correlation analysis. The results showed that both variables were positively correlated to yield losses, which were significantly affected by the level of resistance. Yield losses in resistant and moderate varieties were at the ranges of 2.13-4.38 and 15, 27.26-40.04, respectively.

Chemical control is still a mainstay for some farmers in shallot center areas such as in Brebes, Central Java. Applications of fungicides that are carried out in these areas are very intensive and are carried out periodically every 3-5 days. The application of fungicides that are too intensive can certainly have a negative impact on functional microbes including biological disease control agents. The purpose of this study was to evaluate the negative impact of the application of several brands of fungicides on the efficacy of T. harzianum as a biological control agent for red onion mole. Experiments were carried out in the field and in the laboratory. The results of the field experiment showed that the combined application of T. harzianum and fungicide did not increase the efficacy of a single application. While the results of laboratory tests with application doses in the field can inhibit the growth of colonies and germination of T. harzianum. Brand-B with active ingredients Carbendazim 12% and Mancozeb 63% can inhibit colony growth and germination 100%.
