“…Also, the highest lipase content in P2 and P2E, may be associated with the larger fungi populations with capacity to penetrate the host cuticle, consisting of chitin (Homthong et al, 2016), contributing to biological control of the soil-borne disease (Boat et al, 2019).…”

“…About 70% of yield losses have been reported in local bean production in Kenya and Rwanda due to Pythium root rot (Nzungize et al, 2012). Not only Pythium, there is a group of pathogens that contribute to root rot of common bean; they are Fusarium spp., Sclerotium spp., and Macrophomina spp (Eke et al, 2020, Bedine et al, 2020. Root rot of common bean causes yield loss of about 221000 metric tons in a year in Saharan Africa (Paparu et al, 2018).…”

Purpose: Country bean (Lablab purpureus L.) is an important pulse crop consumed as a vegetable in the central and south-western regions of Bangladesh after eggplant and tomato. It promises to ameliorate nutritional demand from vegetables and has an excellent possibility for the world market. But the production is hampered due to infection of several diseases in field conditions.Research Method: This study was undertaken based on secondary data of existing literature from Bangladesh and other parts of the world. So far, many research works were done on this issue but those were not available to the policymakers, extension workers, and public in a systematic manner to date. Findings:In this paper, we tried to bring forth different aspects of phytopathological problems of country bean. It usually undergoes stresses from different soilborne to seed-borne pathogens and expresses symptoms from the seedling stage to maturity. Crop protection largely depends on the integration of host plants, seeds, agronomic practices, environmental footprints, and the use of appropriate agrochemicals based on the epidemiology of target pathogens. Here, we have also described effective management strategies against respective pathogens of the diverse category. These microorganisms attack at different stages of crop growth and can affect the host plants enormously to cause maximum yield loss. Research Limitations:The study focused on the management of country bean diseases based on biological and chemical approaches. It presents limited information on specific technologies in different agroecological zones.Originality/ Value: This study identified research gaps among Bangladesh and other countries. It also provides information to combat country bean diseases to the economic threshold level for ensuring sustainable crop yield.

“…Volatile organic compounds play an important role in the protection of plants against pests and pathogens. Volatiles produced by T. asperellum were tested against Fusarium oxysporum, Fusarium solani, Macrophomina phaseolina and Pythium ultimum (Boat et al 2020). As a result, it was found that fungus produced volatile and non-volatile inhibitory metabolites as well as hydrolytic enzymes (chitinase, cellulase, protease and lipase).…”

The protective effects of Trichoderma asperellum IZR D-11 as a biocontrol agent against the powdery mildew Erysiphe alphitoides infecting leaves of Quercus robur were evaluated for the first time. A strain of Trichoderma had earlier been isolated in Belarus, and was identified in this study as T. asperellum by sequencing of three genomic markers: internal transcribed spacer, translation elongation factor 1 alpha and RNA polymerase II subunit 2, with over 99.2% identity to corresponding genomic sequences in GenBank. When applied once in the first year just after onset of powdery mildew disease, T asperellum IZR D-11 reduced disease progression and continued to reduce powdery mildew levels during the following three years. Photosynthetic activity as represented by chlorophyll fluorescence measured in oak seedlings was increased in treated plants, and greater assimilate production was also found. The use of this antagonistic fungus increased the total water content in oak leaves suggesting that T. asperellum IZR D-11 can serve as a preventive measure to reduce energy losses in the process of water transpiration. GC-MS analysis detected 49 volatile compounds in the headspace of pure cultures of T. asperellum. Sesquiterpenes represented mainly by daucene, dauca-4(11),8-diene and isodaucene were the largest group of compounds emitted. We speculate that these volatiles from T. asperellum IZR D-11 may be involved in induced resistance in the plant, but further research is needed. The above results suggest that T. asperellum strain IZR D-11 has potential as a biocontrol agent of oak powdery mildew in forest nurseries.
