“…Daba et al [7] considered the Macrotermes species as minor pests infesting pepper gardens in major producing areas of Ethiopia due to their very low infestation level, although they had a wide distribution. However, under termites-fungi interactions, fungi might function as pathogens/lethal parasites to the termites [55]; they can also act as symbionts, attractants, antagonists, or even synergists to the termites [56,57]. e ability of termites to survive and interact with soil fungi could be supported by the lower density of the fungi in soil (or concentration of fungal conidia, spores/mycelium) and the antifungal compounds (peptide termicin) released in termite saliva from the gut during hygienic and grooming activities.…”

Pepper (Piper nigrum L.) serves as a source of income to smallholder spice farmers in Morogoro district of Tanzania. Recently, spike shedding and stem wilting of pepper plants were reported to cause about 30% yield loss of the crop. This study was undertaken to identify the causal agent(s) of the problems. Three pepper gardens in each of the four hamlets (Nyange, Doga, Tandai, and Lukenge) in Tandai village (Kinole ward) were surveyed, and plant tissue and soil samples were collected for laboratory analysis. An experiment was laid out in a randomized complete block design with three replications. Pepper cultivars, Babu kubwa, Babu ndogo, Babu kati, and Ismailia grown in the study area, were used as treatments for evaluation of the prevalence of spike shedding and stem wilting. Treatments mean separation was conducted based on Duncan’s multiple range test at p = 0.05 . Regression (R2) and simple correlation (r) analyses between stem wilting (incidence and severity) and termite pest infestation were performed. The identified pathogen in most of the soil and plant tissue samples was Fusarium oxysporum. The nutrients, N, P, Mg, and Cu, concentration in soil and leaf samples was below the optimal ranges. Termite attacks were significantly high in some farmer’s gardens where up to 50.5% of the pepper plants was damaged. Hence, a significant positive correlation was observed between termite pest infestation in gardens and both incidence (r = 0.881, R2 = 0.74, p < 0.001 ) and severity of stem wilting (r = 0.918, R2 = 0.84, p < 0.001 ) of pepper plants. Most of the termite attacks and damages (70%) were observed on pepper plants supported on silver oak, unlike those trained on Jatropha. A higher percentage of undeveloped berries (36%) and intermediate-size berries (34%) was recorded on cultivars “Babu kati” and “Babu kubwa,” respectively. Multiple factors have been associated to be the causes of spike shedding and stem wilting of pepper, which could be used to develop appropriate control solutions useful to farmers. Confirmation of F. oxysporum pathogenicity is recommended. A comprehensive study is suggested on the repellent or lethal activities of Jatropha against F. oxysporum and termites. Furthermore, studies through field experiments are needed to generate site-specific soil nutrient improvement recommendations and design an integrated approach to control F. oxysporum and termites and to determine existing alternative host plants for these pests.

Actinobacteria is a phylum and class of Gram-positive bacteria. The phylum Actinobacteria are classified into six classes namely Acidimicrobiia, Actinobacteria, Coriobacteriia, Nitriliruptoria, Rubrobacteria and Thermoleophilia. Members of phylum Actinobacteria are ubiquitous in nature. Actinobacteria can be utilized as biofertilizers for sustainable agriculture as they can enhance plant growth and soil health though different plant growth promoting attributes such as solubilization of phosphorus, potassium and zinc, production of Fe-chelating compounds, phytohormones hormones such indole acetic acids, cytokinin, and gibberellins as well as by biological nitrogen fixation. The Actinobacteria also plays an important role in mitigation of different abiotic stress conditions in plants. The members of phylum Actinobacteria such as Actinomyces, Arthrobacter, Bifidobacterium, Cellulomonas, Clavibacter, Corynebacterium, Frankia, Microbacterium, Micrococcus, Mycobacterium, Nocardia, Propionibacterium, Pseudonocardia, Rhodococcus, Sanguibacter and Streptomyces exhibited the multifarious plant growth promoting attributes and could be used as biofertilizers for crops growing under natural as well as under the abiotic stress conditions for plant growth and soil health for sustainable agriculture.

The extreme environment of low temperature is one of the major abiotic stresses acting as the limiting factor affecting the agricultural productivity. 20% of the Earth's surfaces were covered frozen soils (permafrost), glaciers and ice sheets, and snow cover area. Extreme low temperature represents unique ecosystems which harbor novel biodiversity which has been extensively investigated in the past few years with a focus on culture-dependent and culture-independent techniques [1-6]. The psychrotrophic microbes have been reported from all three domains of life archaea, bacteria, and eukarya and belong to different phylum, namely Actinobacteria, Planctomycetes,
