“…In general, three successive extractions are carried out with the same volume of solvent. 56,68,[76][77][78][79] In some cases, several extractions are carried out using successively hexane, chloroform, ethyl acetate and butanol due to their increasing polarity, to explore the widest diversity of metabolites. 70,76,80,81 This strategy allows a finer characterization of the metabolites because each fraction can be analyzed.…”

Among the alternatives to synthetic plant protection products, biocontrol appears as a promising method. This review reports on the diversity of fungal secondary metabolites phytotoxic to weeds and on the approach generally used to extract, characterize, identify and exploit them for weed management. The 183 phytotoxic fungal secondary metabolites discussed in this review fall into five main classes of molecules: 61 polyketides, 53 terpenoids, 36 nitrogenous metabolites, 18 phenols and phenolic acids, and 15 miscellaneous. They are mainly produced by the genera Drechslera, Fusarium and Alternaria. The phytotoxic effects, more often described by the symptoms they produce on plants than by their mode of action, range from inhibition of germination to inhibition of root and vegetative growth, including tissue and organ alterations. The biochemical characterization of fungal secondary metabolites requires expertise and tools to carry out fungal cultivation and metabolite extraction, phytotoxicity tests, purification and fractionation of the extracts, and chemical identification procedures. Phytotoxicity tests are mainly carried out under controlled laboratory conditions (not always on whole plants), while effectiveness against targeted weeds and environmental impacts must be assessed in greenhouses and open fields. These steps are necessary for the formulation of effective, environment‐friendly fungal secondary metabolites‐derived bioherbicides using new technologies such as nanomaterials.This article is protected by copyright.

“…After many years of study, there is no conclusive result or commercial application, even with breeding and release of adults. Other types of widely studied biocontrol agents are fungi [62] and bacteria [63] that have shown certain levels of control in pot studies under controlled conditions, but conclusive results from field studies have not yet been reported, highlighting above all the difficulty of finding a viable method of application and persistence [64]. The use of a series of natural metabolites produced by fungi or plants has also been proposed [65,66], which has shown an effect in the laboratory, but the mode of extraction or synthesis of these metabolites as well as their incorporation into the field must be optimized to make them applicable.…”

Grain and forage legumes are important sources of food and feed, key for sustainable agriculture given the environmental services they provide. However, their cultivation is hampered in the Mediterranean Basin and Near East by the widespread occurrence of the root parasitic weed crenate broomrape (Orobanche crenata). Other broomrape species such as O. minor, O. foetida, and Phelipanche aegyptica are also of local importance. As for other parasitic weeds, a number of management strategies have been proposed, but considering that temperate legumes in the area are low-input crops, these strategies are largely uneconomical or hard to achieve, leaving the use of resistant cultivars as the most desirable option. Breeding for broomrape resistance is not an easy task, but significant progress has been achieved by classical breeding and selection and will profit from recent developments in phenomics and genomics. Here, achievements and prospects in broomrape management and resistance breeding are presented and critically discussed.

Safe methods as alternative approaches to chemical herbicides for controlling parasitic weeds associated with nutritional crops: a review

2021

View full text Add to dashboard Cite

Weeds are among the important pests of agricultural and nutritional crops causing major yield loss, ranged between 10% to 98% of total crop yield, which may vary from crop to other or region to other in the same crop. This loss in crop yield results when parasitic weeds attach themselves to another plant, their 'host', and draw nutrients from it causing huge damage to the host crop and consequently huge economic loss. Orobanche spp., Striga spp. and Cuscuta spp. are the most common parasitic agricultural weeds with economic importance in many world parts. Applying control methods selective enough for killing these parasitic weeds without causing crop damage is as difficult as the application of chemical herbicides which causing soil and water contamination and adverse effects to beneficial organisms and hence loss in the nutritional benefits of the cultivated crop. In some cases chemical compounds which resulting from herbicide degradation process may continue to be significantly toxic to health and environment. A review was made to highlight research conducted yet concerning important alternative methods to herbicides, such as biological control; natural products; agricultural practices and cropping systems, for controlling parasitic weeds and their management in nutritional crops.
