“…They concluded that both extracts of marigold stem and leaves with 6% concentration significantly reduced the percent of infected plants. In another study, Al-Hussaen, et al [44] recommended the use of garlic plant extracts to control Pythium ultimum on tomato seedlings since it is considered as an environmentally friendly product. Undiluted garlic extract showed the highest control activity with no growth as compared to the biotic control without the extract whereas diluted garlic extracts 10 and 5% reduced the fungal growth to 15.5 and 41%, respectively.…”

Tomato (Lycopersicon esculentum L.) is one of the most popular and important commercial vegetable crops grown throughout the world. Tomato is a rich source of various micronutrients and antioxidants. One of the major causes of poor quality and fruit loss during storage and transport are diseases caused by phyto-pathogenic fungi. Fusarium wilt of tomato caused by Fusarium oxysporum lycopersici becomes one of a limiting factor in the production of tomato and accounts for yield losses in Jordan and the whole world. It is considered as one of the most prevalent and damaging diseases wherever tomatoes are grown because the pathogen persists in infested soils. Pathogenic fungi of the genus Fusarium, cause root and basal stem deterioration and result in the wilting of vegetable plants. Browning of the vascular tissue is a strong evidence of fusarium wilt. Because of hazards of pesticides in general, and fungicides in specific, on public health and environmental balance, new direction of pest control management was introduced. Biological management of Fusarium wilt of tomato using bio-fortified composts associated with selected biological control agents (Fungal and bacterial species) is studied. Recently, different reports stated that some plant extracts and plant essential oils have been reported to be effective antimicrobial agents against food and stored grain fungi, foliar pathogens, and soil-borne fungal phyto-pathogens. This review is aimed at investigating the occurrence of Fusarium wilt of Tomato in Jordan and summarizing the best ways of management and control, especially the biological means.

“…Several chemical fungicides are used widely to manage fungal diseases of agricultural crops. The adverse effects of the environmental residuals of these fungicides have generated much concern regarding the health of humans and the functioning of beneficial soil microbiota 1 . This has led to the demand for eco‐friendly measures with better performance than commercial fungicides to control the plant diseases in a sustainable manner 2 .…”

BACKGROUND Lipopeptides from the Bacillus spp. possess an excellent spectrum of antimicrobial properties which make them suitable candidates to be explored for the food, agricultural, pharmaceutical and biotechnological applications. As the low yield of the lipopeptides limits their applications, methods to enhance their production are highly significant. RESULTS In this study, extracts prepared from endophytic Bacillus sp. Fcl1 cultured in the presence of various supplements were screened for antifungal activity against Pythium aphanidermatum. From the results, the supplementation of carbon sources and zinc oxide nanoparticles (ZnONPs) was found to have an enhancement effect on the antifungal activity of Bacillus sp. Fcl1. Among these, the highest antifungal activity (73.2%) could be observed for the Fcl1 sample cultured with 5 mg L−1 of ZnONP supplementation. The growth of Fcl1 in the presence of ZnONPs also indicated its compatibility with the nano‐supplement in the concentration range used. By liquid chromatography quadrupole time‐of‐flight mass spectrometry (LC‐Q‐TOF‐MS) analysis, the synthesis of increased numbers of lipopeptide surfactin derivatives could be identified from the extracts of Fcl1 prepared from the carbon sources and ZnONP‐supplemented cultures. In addition to the surfactin derivatives, the presence of another lipopeptide iturin was also detected from the extracts of Fcl1 cultured with ZnONPs. CONCLUSION ZnONP supplementation was found to enhance antifungal activity and lipopeptide production in the Bacillus sp. Fcl1. The use of nanoparticles to enhance the antifungal mechanisms of Fcl1 as observed in the study provides novel insights to explore its applications for sustainable agricultural productivity.
