“…studies have demonstrated that microorganisms and essential oils can be used as a biocontrol agent in controlling a number of plant diseases with a high efficacy i.e. extract of lantana showed broad antifungal activity against Aspergillus flavus and A. niger (Fayaz et al 2017), Colletorichum falcatum (Sreeramulu et al 2017). Also, charcoal rot infection was substantially reduced by seed coating of mungbean and sunflower by T. harzianum, Gliocladium virens and Streptomyces sp.…”

“…Methanol leaf extract of lantana showed broad (Fayaz et al 2017). Aqueous and methanolic leaf extracts of lantana showed significant inhibition against Colletorichum falcatum (the causal fungi of sugarcane red-rot disease) under in vitro conditions (Sreeramulu et al 2017). The water and ethanol extracts of acalypha leaf inhibited the growth of standard and local strains of bacteria and fungi including Staphylococcus aureus, Trichophyton rubrum, Trichophyton mentagrophytes, Candida albicans and Aspergillus flavus (Alade and Irobi 1993).…”

Plant extracts are among the biological control agents that directly affect the plant pathogens and can induce resistance in plants against phytopathogens (Mishra and Raja 1999). Recently, plant extracts have gained considerable attention as alternative options to synthetic fungicides and efforts have been made to utilize these extracts in the control strategies against plant diseases (Srivasata et al. 2011; Elsharkawy and El-Sawy 2015). It has been previously proven that plant extracts are effective control agents L EAF rust, caused by Puccinia triticina Eriks., is among the most common wheat rust diseases in Egypt causing major losses in the grain yield. The objective of this study was to evaluate the efficacy of water and 80%-methanol extracts prepared from seven different plants (henna, blue gum, acalypha, chinaberry, pomegranate, basil, and lantana) in controlling the leaf-rust disease of wheat. In an in vitro experiment, all methanol extracts inhibited the germination of the fungus spores by more than 98%, while water extracts were less effective. The methanol extracts of henna, lantana, acalypha, chinaberry, and pomegranate exhibited a 100%-inhibition of spore germination. In addition, no significant differences were recorded between the methanol extracts of these five plants and the synthetic fungicide Fungshou. In a filed experiment, wheat plants were one-and two-time sprayed with henna, lantana, acalypha, chinaberry, and pomegranate water or methanol extracts. The results revealed that all plant extracts not only decreased the disease severity of the leaf rust, but also enhanced the grain yield components including spike weight, the 1000-kernel weight, and the test weight. Furthermore, the two-time spray application was more effective than the one-time spray. Our study indicated that water and methanol extracts of henna, lantana, acalypha, chinaberry, and pomegranate might be utilized for the control of wheat leaf-rust disease as a safe and environmentally friendly alternative to synthetic fungicides.

“…Reports of Daniel et al [33] showed that garlic effectively inhibited Botrytis cinerea in vitro. Tick berry extracts were reported to effectively inhibit the growth of P. infestans [34,35] and Colletotrichum falcatum that causes red rot disease of sugar cane [36]. Mexican marigold extracts were also reported to significantly suppress the root-knot nematodes that infect tomato [37] and to have antibacterial effects against Escherichia coli and Staphylococcus aureus [38].…”

Tomato production is constrained by fungal diseases especially the early and late blight caused by Alternaria solani and Phytophthora infestans, respectively. Control of the two diseases is usually by use of synthetic fungicides which have a long residue effect and also contribute to environmental pollution. Innovative use of biocontrols may offer an eco-friendly and more sustainable solution. This study tested the in vitro efficacy of crude extracts and essential oils of ginger, garlic, tick berry, and Mexican marigold in inhibition of radial growth of A. solani and P. infestans. Extraction of the crude extracts was done using distilled water, ethanol, and methanol solvents, while essential oils were extracted using the dry steam distillation method. The extracts and essential oils were used to amend the growth media of the test pathogens before introducing the precultured pathogens. Sterile distilled water and synthetic fungicide, Ridomil Gold®, were used as positive and negative controls, respectively. Fungal growth inhibition was determined by measuring the radial growth of the test pathogens. Both the crude extracts and the essential oils portrayed some efficacy against the test pathogens. Garlic crude extracts were found to be the most effective, while ethanol was the most suitable extraction solvent. Essential oils were more effective in restricting the pathogen growth than crude extracts. Ginger and garlic oil was found to be as effective as the synthetic fungicide, and thus it was concluded that the two plants have strong antifungal properties with high potential of being utilized as biofungicides. However, effective utilization of these products in farmers’ fields may require industrial formulation to improve their efficiency.
