“…The initial volume of each composting pile was about 1 m 3 and occurred in wire mesh containers protected by a windshields plastic net to avoid excessive heat and moisture loss, while allowing natural air movement. Chemical, physical and microbiological parameters were monitored during the composting process as described by Coelho et al (2020).…”

“…In comparison with all the fungi isolated in composts P1 and P2, T. atroviride showed the best results as a biological control agent, with higher inhibition rates of phytopathogenic fungi (Coelho et al, 2020). A suspension of T. atroviride was obtained by adding 50 mL of sterilized distilled water to Petri dishes where the fungus had grown for seven days.…”

“…Composts from organic residues, due to their large and diverse microbial populations, can be one of the best solutions for plant diseases biological control (Bernal-Vicente et al, 2008;Alfano et al, 2011;Liu et al, 2016;Coelho et al, 2020). In addition, composts are also known for their potential as fertilizers, namely due to their high organic matter content.…”

“…Two applications of T. harzianum caused the pathogens were difficult in attacking soybean plants, so its production is higher. T. harzianum is capable of decomposing organic materials from rice husk, and in the decomposition process, the antagonist alters elements in a dissolved form so they can be absorbed by plants (Coelho et al 2020). According to Suryawan et al (2017) Potassium element in rice husk that can increase plant resistance to disease and antagonist able to inhibit disease progression.…”

Abstract. Martanto EA, Tanati AE, Baan S, Tata HR, Murdjoko A. 2020. Effectiveness of biological control of Trichoderma harzianum on soybean leaf rust disease and the production in West Papua Lowland, Indonesia. Biodiversitas 21: 1935-1939. This study aims to evaluate the application of Trichoderma harzianum in leaf rust disease on soybean and its production. The study was conducted for three months starting from May to July 2017, at Residential Unit 11th Sidey Subdistrict, Manokwari District, West Papua Province, Indonesia. This study was designed using Factorial Complete Randomized Design consisting of two treatment factors and repeated three times. There was no treatment of pathogen inoculation in the field. The tested varieties had a different response to plant height. Burangrang, Grobogan, Dena-1, Anjasmoro, and Detam-1 varieties were categorized as moderate resistant varieties. The Trichoderma harzianum application should be applied in the whole crops of soybean to control environmentally the leaf rust disease. Seeds weight per plot for Dena-1 variety was higher compared to other varieties. The combination of Detam-1 varieties with Trichoderma treatment 2 times resulted in increased production.

“…Trichoderma harzianum tends to perform better when nutrients are available and initial pathogen levels are low, indicating the most suitable application timing as a preventative application [16]. Trichoderma atroviride suppressed Clarireedia spp on creeping bentgrass by 67.5% [17].…”

Clarireedia jacksonii sp. nov. Formerly Sclerotinia homoeocarpa F.T. Bennett, the causal agent of dollar spot (DS), is the most destructive pathogen in turfgrass. Symptoms appear as circular patches 10-40 mm in diameter with small tan lesions surrounded by a darker band, sometimes presenting an hour glass appearance. A multi-year study was initiated with the objective of determining the effi cacy of biological control agents (BCA) and tank mixes of BCA's and synthetic fungicides on DS control. Nutrient source was also evaluated to determine any interaction with the BCA's and tank mixes. In vitro studies evaluated the effi cacy of synthetic and BCA's for C. jacksonii control. Quarter strength potato dextrose agar was amended with ¼, ½ and full labeled rates of various products. Chlorothalonil at all rates provided greatest (> 90%) control of C. jacksonii for study duration. Biological control agents provided best effi cacy at ¼ and ½ label rates. Streptomyces griseoviridis provided least effi cacy and may have exacerbated formation of C. jacksonii. Preventative fi eld evaluations for synthetic and BCA's provided different results between two study years. In Year 1, all treatments had < 15% disease severity for the duration of the study. In year 2, disease pressure was extremely elevated. Synthetic program 1, centered on azoxystrobin + propiconazole applications and conventional fertility sources, provided best results with < 5% disease severity for the duration of the study. Reduced synthetic program 1, and synthetic program 2 followed closely with < 10% disease severity. Reduced synthetic programs were based on monthly applications of either chlorothalonil or pyraclostrobin every 30 day, alternated with biofungicide applications. Synthetic program 2 utilized rotation applications of pyraclostrobin and chlorothalonil every 14 days. Organic programs, utilizing only biofungicides and organic fertility sources, provided the least amount of control and exceeded the 15% threshold by the second month of the evaluation period.
