“…This shows that in the same plant genus, pathogenic fungi can cause disease in one species, but in other species, pathogenic fungi may not necessarily cause disease (Li et al, 2020). Soesanto et al (2020) reported that Chaetomium sp. can cause disease in weeds, but in cultivated plants Chaetomium sp.…”

Weed pathogenic fungi play an important role in biological control of weeds. Weeds grow a lot among cultivated plants, the role of weed pathogenic fungi to cultivated plants is not yet known. This research aimed to determine the effect of weed pathogenic fungi on bok choy. The research was carried out in Tambaksogra Village, Sumbang District, Banyumas Regency at an altitude of 100 m above sea level. Randomized block design was used with treatments of weed pathogenic fungi (Fusarium sp., Curvularia sp., Chaetomium sp., Fusarium sp. + Curvularia sp., Fusarium sp. + Chaetomium sp., Curvularia sp. + Chaetomium sp., and Fusarium sp. + Curvularia sp. + Chaetomium sp.) repeated four times. The observed variables included symptoms, incubation period, disease intensity, disease incidence, infection rate, AUDPC, number of leaves, plant height, and plant fresh and dry weight. Results showed that Curvularia sp., Chaetomium sp., and Curvularia sp. + Chaetomium sp. did not affect on bok choy, while Fusarium sp., Fusarium sp. + Curvularia sp., Fusarium sp. + Chaetomium sp., and Fusarium sp. x Curvularia sp. + Chaetomium sp. caused disease intensity of 2.7, 2.7, 3.55, and 4.4%, respectively, and affected plant dry weight by 113.35, 82.36, 77, and 74.07 %, respectively, from control. Curvularia sp., Chaetomium sp., and Curvularia sp. + Chaetomium sp. could be used as a bioherbicide in bok choy cultivation.

This research aimed to determine the effect of secondary metabolites from weed pathogenic fungi (Fusarium oxysporum. Curvularia sp., and Chaetomium sp.) on narrow leaf weeds and on cultivated plants. The research was conducted at the Laboratory of Plant Protection and the experimental farm, Faculty of Agriculture, Jenderal Soedirman University for five months. Split plot design was used with main plot consisted of the pathogenic fungi Fusarium oxysporum, Curvularia sp., and Chaetomium sp. and subplots consisted of Imperata cylindrica, Cyperus kyllingia, and Cynodon dactylon, and maize, and rice. The variables observed were the incubation period, disease intensity, infection rate, disease area under progress curve (AUDPC), plant height, fresh plant weight, and dry plant weight. Results of the research showed that the secondary metabolites of three weed pathogenic fungi were able to infect narrow leaf weeds. From the single effect of the pathogen, the secondary metabolites of Curvularia sp. were the most virulence against narrow leaf weeds with increasing incubation period, disease intensity, infection rate, and AUDPC value as 79.90, 39.91, 14.4, and 99.69 %, respectively, compared to control. The secondary metabolites decreased plant height, fresh plant weight, dry plant weight as 26.66, 65.03, and 47.23 %, respectively, compared to control. From the single effect of weeds, the most susceptible weed was Cynodon dactylon indicated by a disease intensity of 28.08 %. From the combination effect, Fusarium oxysporum on Cynodon dactylon and Curvularia sp. on Cyperus kyllingia showed the highest disease intensity, respectively, as 53.08 and 48.14 %. The secondary metabolites of three weed pathogenic fungi were not virulence to rice and corn.

“…Weed pathogenic fungi, i.e., Chaetomium sp., Fusarium sp., and Curvularia lunata, were prepared in PDA (Soesanto et al 2020). Furthermore, the three weed pathogenic fungi were propagated using three liquid media, i.e., Potato Dextrose Broth (PDB), rice washing water, and tofu liquid waste, which were shaken out at 150 rpm (Daiki) at room temperature for 7 days.…”

Abstract. Soesanto L, Mugiastuti E, Manan A. 2021. The use of alternative liquid media for propagation of pathogenic fungi and their effect on weeds. Biodiversitas 22: 719-725. Weeds cause high yield losses and are controlled by chemical, physical and mechanical control. Weed pathogenic fungi could be used as a biological control agent. However, the propagation media of them are still a higher cost, therefore, the new alternative and inexpensive media for weed pathogenic fungi propagation are required. The propagation of weed pathogenic fungi in liquid media in-vitro used randomize completely design consisted of three pathogenic weed fungi, i.e., Chaetomium sp., Fusarium sp., and Curvularia lunata and three liquid media, i.e., PDB, rice washing water, and tofu liquid waste. The in-planta tests used split-plot design used weed pathogenic fungi multiplied in the best formula from in-vitro results (rice washing water) and control as the main plot and four weeds, i.e., Cyperus kyllingia, Cynodon dactylon, Portulaca oleracea, and Ageratum conyzoides as subplot. The variables observed were conidia density, incubation period, disease intensity, number of leaves, and weed height. The results showed that rice washing water and tofu liquid waste were suitable media for the propagation of the weed pathogenic fungi. Chaetomium sp. was virulent fungi against broad leaves weeds, especially A. conyzoides. This fungus can be promoted to manufacture organic herbicides against the weed.
