“…These fungi grow very fast and have high sporulation capacity and are tolerant to heat. Dominance of Trichoderma in dam soils may provide benefits to growers using dam soils in their farms as several species of Trichoderma have been reported as potential biological control agents (Watanabe et al, 2005;John et al, 2010;Al-Sadi et al, 2015c;Diánez Martínez et al, 2015).…”

The study analyzed fungal diversity in soil trapped behind dams in three arid regions of Oman, in the south-eastern part of the Arabian Peninsula. Physicochemical analysis indicated that soils are of the loamy sand or sandy loam types and they are deficit in some macro and micro elements. Culture-based techniques revealed variation between dam soils in the number and type of phyla, classes, orders, genera and species. Ascomycota was the most dominant phyla in the three samples, contributing to 89% of the total species. Eurotiomycetes, Sordariomycetes and Dothideomycetes were the most common classes in dam soils. Zygomycetes, Pezizomycetes and Oomycetes were also detected, but at lower levels. Fifty fungal taxa were recovered from the three dam soils, with Aspergillus, Penicillium and Trichoderma being the most common genera. Most of the detected species were saprophytes; however some were either plant pathogens or mycotoxin producers, affecting humans directly or indirectly. This study appears to report for the first time 20 fungal species in Oman. It is also the first study from arid regions to characterize high fungal diversity in soil trapped behind dams. The sources of these fungi in dam soils and the implications of fungal diversity are discussed.

“…Trichoderma from rhizosphere, promoted growth of wheat and soybean under greenhouse conditions (Rojan et al, 2010). Some early work revealed that Trichoderma also promotes growth responses in some other crops viz., bean (Phaseoulus vulgaris L.), cucumber (Cucumis sativus L.), pepper (Capsicum annum L.), wheat (Triticum aestivum L.), radish (Raphanus sativus), bitter guard (Momordica charantia), loofah (Luffa Acutangula Roxb) and tomato (Solanum lycopersicum).…”

A three year study (2008)(2009)(2010)(2011) on the validation of the Trichoderma technology for growth promoting ability of Trichoderma harzianum (Th3) was evaluated in the popular wheat (Triticum aestivum L.) variety Raj 3765 at farmer's field through TIFAC-DST project entitled "On Farm Demonstration and Commercial Production of Trichoderma as Biopesticide and Growth Promoter". The biological formulation was developed at Biological Control Laboratory, Division of Plant Pathology, IARI, New Delhi, and was successfully demonstrated in two districts of Rajasthan viz., Jaipur and Kota belonging to different agro climatic zones. Rhizospheric Competence Index along with its growth promotion effect on rootlets, tillers, weight of grains and grain yield were evaluated by using it at three stages of crop viz., seed, flowering and preharvesting @ 4g/kg and @ 4ml/L along with soil treatment with a mixture of farm yard manure and formulation @ 50:1 before sowing. Compared to the first year where the farmers were unaware of Trichoderma in 2008-09, a significant increase in yield of wheat from 36.25 to 46.73Q/ha (29% in Jaipur) and from 36.88 to 50.12Q/ha (36% in Kota) has been observed after continuous application for three years (2008)(2009)(2010)(2011) The total income and the benefit cost ratio of farmers increased both at Jaipur (Rs 56242/ha, 1:1.8) and Kota (Rs 60332/ha, 1:1.9).

“…The most effective strains of some of these organisms are now commercial products. The fungus Trichoderma viride has been developed into biocontrol products to be used against soybean pathogens including Fusarium oxysporum and Pythium arrhenomanes [24], and several species of the bacterial genus Bacillus have been shown to suppress the soybean cyst nematode. A specific strain B. pumilus GB34, has been developed as a commercial product.…”

Organically Grown Soybean Production in the USA: Constraints and Management of Pathogens and Insect Pests

et al. 2016

View full text Add to dashboard Cite

Soybean is the most produced and consumed oil seed crop worldwide. In 2013, 226 million metric tons were produced in over 70 countries. Organically produced soybean represents less than 0.1% of total world production. In the USA, the certified organic soybean crop was grown on 53 thousand ha or 0.17% of the total soybean acreage in the USA (32 million ha) in 2011. A gradual increase in production of organically grown soybean has occurred since the inception of organic labeling due to increased human consumption of soy products and increased demand for organic soybean meal to produce organic animal products. Production constraints caused by pathogens and insect pests are often similar in organic and non-organic soybean production, but management between the two systems often differs. In general, the non-organic, grain-type soybean crop are genetically modified higher-yielding cultivars, often with disease and pest resistance, and are grown with the use of synthetic pesticides. The higher value of organically produced soybean makes production of the crop an attractive option to some farmers. This article reviews production and uses of organically grown soybean in the USA, potential constraints to production caused by pathogens and insect pests, and management practices used to reduce the impact of these constraints.
