“…These results indicated that these two DSE fungal isolates were resistant to mancozeb concentration up to 400 ppm (Figure 1). Malandrakis et al (2018) reported that the nonpathogenic Fusarium solani endophytic fungi was insensitive to mancozeb at a concentration of 100 µg/mL. Spagnoletti and Chiocchio (2019) also reported DSE fungi Alternaria alternata and Cochliobolus sp.…”

Mancozeb is a group member of dithiocarbamat fungicides that most widely applied in the field. The use of mancozeb causes residues that have negative effects on agricultural production system and on agricultural environment. This research aimed to obtain dark septate endophyte (DSE) fungal isolates that are tolerant to mancozeb fungicide. The study was consisted of three steps, i.e., the isolation of DSE fungi from chili roots, the effect of DSE fungal isolates on chili seeds, and the growth ability of DSE isolates on medium supplemented with mancozeb. Thirteen DSE fungal isolates were isolated from chilli pepper roots and grown in the field assumed to be contaminated by pesticides. The isolates of DSE fungi caused the growth of chili seeds were normal and abnormal. Seven DSE isolates were able to grow well at PDA medium suplemented with mancozeb at concentrations of 100, 200, 400, and 800 ppm with different levels of relative growth inhibition. Mancozeb on PDA medium influenced the mycelial growth and colony color of DSE fungal isolates. The biomass of DSE fungal isolates were reduced when they were grown at malt extract broth (MEB) medium suplemented various levels of mancozeb. ABSTRAKMankozeb adalah kelompok fungisida ditiokarbamat yang paling banyak digunakan di lapangan. Penggunaan mankozeb yang tidak sesuai dapat menyebabkan dampak negatif pada sistem produksi dan lingkungan pertanian. Penelitian ini bertujuan untuk memeroleh isolat cendawan Dark Septate Endophyte (DSE) yang toleran terhadap fungisida berbahan aktif mankozeb. Penelitian terdiri atas tiga tahap, yaitu isolasi cendawan DSE dari akar tanaman cabai, pertumbuhan isolat cendawan DSE pada tanaman cabai, dan kemampuan tumbuh cendawan DSE pada media yang mengandung mankozeb. Berdasarkan hasil penelitian diperoleh 13 isolat cendawan DSE dari akar tanaman sawit yang terkontaminasi oleh penggunaan pestisida. Isolat cendawan DSE yang diperoleh menyebabkan pertumbuhan benih cabai normal dan tidak normal. Tujuh isolat cendawan DSE mampu tumbuh dengan baik pada media PDA yang telah diberi penambahan konsentrasi mankozeb, yaitu 100, 200, 400, dan 800 ppm dengan hambatan pertumbuhan relatif yang berbeda. Penambahan mankozeb pada media PDA memengaruhi pertumbuhan miselium dan warna koloni isolat cendawan DSE. Pertumbuhan cendawan DSE pada media cair Malt Extract (ME) yang ditambahkan konsentrasi mankozeb menyebabkan penurunan biomassa cendawan DSE. Kata kunci: ditiokarbamat, hambatan pertumbuhan relatif, toleran

“…Beberapa fungisida akan memengaruhi kelimpahan endofit di dalam tanaman dengan tingkat sensitivitas yang bervariasi (Cadez et al 2010). Malandrakis et al (2018) melaporkan bahwa cendawan endofit Fusarium solani tidak sensitif terhadap fungisida thiophanate-methyl, fenhexamid, cyprodinil, boscalid, dan mankozeb, tetapi sangat sensitif terhadap fungisida prochloraz, fludioxonil, pyraclostrobin, dan difenokonazol.

Application of fungicides to control rice diseases potentially have adverse effect on non target organisms including endophytic fungi. Unfortunately, information of fungicide effect on endophytic fungi on rice is still limited. The purpose of this research was to study the diversity and abundance of endophytic fungi on rice plant because of application of synthetic fungicides. There were two treatments in this study: non systemic fungicide (mankozeb) and systemic fungicide (difenoconazole) which were compared to control (without fungicide). Isolation of endophytic fungi and application of fungicides were conducted every week started at aged of 3 to 10 weeks after planting. Variables observed were total segment of rice colonized by endophytic fungi, colonization frequency of endophytic fungi, continued by identification and analysis of the diversity of endophytic fungi. This study showed that there was an increase in colonization of endophytic fungi with an increase of plant ages. The diversity of endophytic fungi was higher in stems than in leaves with the value of H' is 0.00-1.35 and 0.00-0.98 respectively. The most common types of endophytic fungi appear in each isolation of rice segments were Acremonium, Curvularia, Fusarium, Helminthosporium, Nigrospora, Penicillium, and Mucor. Both fungicides do not significantly affect the percentage of colonization and diversity of endophytic fungi. At the beginning of planting (4-6 MST) there was a decrease in the percentage of endophytic fungal colonization in the stem. From the percentage of colonization of each genus of fungi, Nigrospora and Fusarium decreased significantly with difenoconazole on the stem during the vegetative phase. Keywords: colonization, community, difenoconazole, diversity, mancozeb

“…Fusarium species are the most common pathogens, which can live in organic materials and nearly all soil types (Boyaci et al, 2010). They can attack the vascular system in infected plants, block water transport through xylem by inducing vessel plugging, leading to foliage wilt and finally plant death (Portal et al, 2018;Malandrakis et al, 2018).…”

Fusarium wilt of tomato plants caused by Fusarium oxysporum Schlecht. emend. Snyder & Hansen and Fusarium solani (Mart.) Sacc. are serious problem limiting tomato production worldwide. Biological control has emerged as one of the most promising alternatives to chemical fungicides. The biological control capability of a T. harzianum isolate against F. solani and F. oxysporum has been investigated. It inhibited colony growth of two Fusarium species by more than 80 % in dual culture tests. Results of greenhouse experiments revealed that disease severity in the tomato plants co-inoculated with T. harzianum was significantly lower than plants only infected with the Fusarium pathogens. Tomato plants inoculated with the antagonistic T. harzianum isolate, showed enhanced peroxidase and polyphenol oxidase activities in greenhouse experiments and increased resistance to F. solani and F. oxysporum. The T. harzianum isolate indirectly affected the Fusarium pathogens by enhancing plant defence.
