“…Anthracnose caused by Colletotrichum show irregularly shaped, dark brown on undersides of leaves and petioles and defoliation. However, a large body of evidence shows that pelleting seed and seed dressing with biocontrol fungal agents Trichoderma harzianum and T. virens are more effective than fungicide treatments against a wide range of root-infecting fungi and results in increased plant growth thus antifungal plant extracts can reduce dry root rot incidence and severity when optimal conditions for their use are provided (Dubey et al 2011;Waheed et al, 2016;Ramzan et al 2016). Antifungal plant extracts can reduce dry root rot incidence and severity when optimal conditions for their use are provided (Waheed et al, 2016).…”

Cowpea anthracnose caused by Colletotrichum lindemuthianum causes about 75 % yield reduction in Cowpea production in Nigeria. Trichoderma harzianum is a bioagent in controlling fungal diseases. Effect of T. harzianum was investigated on growth, disease incidence and yield of selected varieties of Cowpea infested with C. lindemuthianum. Four improved Cowpea varieties were selected IT07K-292-10, IT07K-318-33, IT98K-205-08, IT99K-573-11 and a local variety DANMISRA. Pure isolate of Colletotrichum lindemuthianum and Trichoderma harzianum were each cultured on PDA. Four concentrations of T. harzianum suspensions were prepared at 1x102 conidia/ml, 1x104 conidia/ml, 1x106 conidia/ml, 1x108 conidia/ml and control . Cowpea seedlings were artificially infested with 1x107conidia/ml of C. lindemuthianum at 22 days after sowing. The experiment was arranged in a complete randomized design (CRD) with three replications. The result indicated that the infested variety IT99K-573-11 treated with T. harzianum at 1x108 conidia/ml was insusceptible and had significantly (p<0.05) increased biomass, number of seeds and low disease incidence (19.1 %) while increase in chlorophyll content, seed number and decreased in the anthracnose incidence was observed at 1x108 conidia/ml concentration. The cultivar IT99K-573-11 appeared tolerant hence is recommendedto farmer for cultivation in C. lindemuthianum infested areas.

Mung bean (Vigna radiata), known as green gram or golden gram, is one of the most important short duration pulse crops grown in India during the kharif, spring and summer seasons. However, its production and productivity has been stationary as the crop is prone to more than one disease and pests [34]. Fungi such as Fusarium spp., Rhizoctonia solani, Macrophomina phaseolina and Pythium spp., produce severe diseases such as root rot, charcoal rot, damping-off and stem rot as well as mycotoxins in the grain [4,26]. These soil-borne pathogens can be controlled by chemicals but use of the chemical pesticides has several negative effects. The use of microbial antagonists is a safe, effective and eco-friendly method for the control of many of these soil-borne pathogens and this is gaining popularity in recent days. These biological agents promote plant growth by nutrient recycling and other processes [30]. Their biocidal effects can occur via local antagonism to soil-borne pathogens or by induction of systemic resistance against pathogens. Several substances produced by antagonistic rhizobacteria have been tested for pathogen control and indirect promotion of growth in many plants [6].

“…The biocontrol of P. aphanidermatum has been achieved using Pseudomonas sp., Trichoderma spp. [20][21][22], Bacillus cereus [23], and B. subtilis [24,25] isolated from various sources. Biocontrol agents are divided into two groups: endophytes, that live inside the plant; and rhizospheric microorganisms, that live attached to or beside plant roots [26,27].…”

This study was conducted to investigate the antagonistic potential of endophytic and rhizospheric bacterial isolates obtained from Citrullus colocynthis in suppressing Fusarium solani and Pythium aphanidermatum and promoting the growth of cucumber. Molecular identification of bacterial strains associated with C. colocynthis confirmed that these strains belong to the Achromobacter, Pantoea, Pseudomonas, Rhizobium, Sphingobacterium, Bacillus, Sinorhizobium, Staphylococcus, Cupriavidus, and Exiguobacterium genera. A dual culture assay showed that nine of the bacterial strains exhibited antifungal activity, four of which were effective against both pathogens. Strains B27 (Pantoea dispersa) and B28 (Exiguobacterium indicum) caused the highest percentage of inhibition towards F. solani (48.5% and 48.1%, respectively). P. aphanidermatum growth was impeded by the B21 (Bacillus cereus, 44.7%) and B28 (Exiguobacterium indicum, 51.1%) strains. Scanning electron microscopy showed that the strains caused abnormality in phytopathogens’ mycelia. All of the selected bacterial strains showed good IAA production (>500 ppm). A paper towel experiment demonstrated that these strains improved the seed germination, root/shoot growth, and vigor index of cucumber seedlings. Our findings suggest that the bacterial strains from C. colocynthis are suppressive to F. solani and P. aphanidermatum and can promote cucumber growth. This appears to be the first study to report the efficacy of these bacterial strains from C. colocynthis against F. solani and P. aphanidermatum.
