In the context of a shift towards pesticide reduction in arable farming, weed management remains a challenging issue. Integrated Weed Management currently recommends agronomic practices for weed control, but it does not integrate the use of biodiversitybased options, enhancing the biological regulation of weeds. Here, wereview existing knowledge related to three potentially beneficial interactions, of crop-weed competition, weed seed granivory, and weed interactions with pathogenic fungi. Our main finding are the following : (1) promoting cropped plant-weed competition by manipulating cropped cover could greatly contribute to weed reduction ; (2) weed seed granivory by invertebrates can significantly lower weed emergence, although this effect can be highly variable because seed predation is embedded within complex multitrophic interactions that are to date not fully understood ; (3) a wide range of fungi are pathogenic to various stages of weed development, but strain efficacy in field trials does not often match that in controlled conditions. We present a framework that superimposes biodiversity-based options for weed biocontrol on a classical Integrated Weed Management system. We then describe the current state of knowledge on interactions between agronomic practices and the organisms at play and between the different biological components of the system. We argue that further advances in our understanding of biodiversity-based options and their performance for weed biocontrol will require farm-scale experimental trials.

“…Infected leaves collected from various sites, yielded a species of Gibbago, identified as Gibbago trianthemae Simmons, a phaeodictyoconidial hyphomycetes fungus reported on horse purslane for the first time in India. Pathogenicity of some fungal pathogens on horse purslane was studied in earlier; the species of fungal pathogens namely Cercospora trianthemae (Chiddarwar,1962), Drechslera (Exserohilum) indica (Bipolaris indica) (Rao and Rao, 1987;Taber et al, 1988), Colletotrichum gloeosporioides (Darshika and Daniel, 1992), Fusarium oxysporum (Darshika and Daniel, 1992;Ray and Lakshmi, 2013), Fusarium semitectum (Darshika and Daniel 1998), Alternaria alternata (Bohra et al, 2005;Gupta and Mukerji, 2001;Ray and Lakshmi, 2013), Paecilomyces varioti Bain.

A b s t r a c t A r t i c l e I n f oTrianthema portulacastrum L., commonly known as desert horse purslane is a member of Aizoaceae, interfere with many economic crops and treated as one of the serious weed in India and around the world. It is a native plant of South Africa but widely distributed in India, Sri Lanka, Pakistan and many parts of the world. It has become a noxious weed due to competition for yields in many crops and causing significant reduction in the yield. For instance, its infestation in cotton, maize and direct-seeded rice reduce crop yields by 32-60%, up to 60-70% infestation of this weed has been reported in pigeon pea and soybean fields and 80-90% in maize and brassica fields. The common weed control methods such as cultural practises, mechanical and herbicide treatments does not consider for the effective management of this weed due to their failures. Recently, the successes of Biological control agents over many herbs and alien weeds attracted researchers with their eco-friendly tactics. Therefore, a systematic field study was conducted for preliminary screening of natural enemies against horse purslane weed which would be an effective biocontrol agent after extensive work. An ascomycetes fungus, Gibbago trianthemae Simmons was isolated from parasitized leaves of horse purslane and the identity was confirmed by relevant literature and the biocontrol potential of the pathogen evaluated.

“…HP (horse purslane) is a very noxious annual herbaceous weed. It is considered as a one principle weed in various field crops, such as mustard, soybean, cotton and maize ( Nayyar et al, 2001 ; Ray and Vijayachandran, 2013 ). It belongs to the Aizoaceae family.…”

To assess comparative losses of Trianthema portulacastrum (HP) relative to other weeds, the experiment was set during consecutive summer seasons 2018 and 2019 at the Research Farm MNS-University of Agriculture, Multan, Pakistan. Experiment consisted three replications which were laid out under randomized complete block design. Experiment consisted of ten treatments viz: weeds free (whole season), HP free till 20 Days after emergence (DAE), HP free till 40 DAE, HP free till 60 DAE, all weeds free 20 DAE, all weeds free 40 DAE, all weeds free 60 DAE, weedy check (all weeds), weedy check except HP and weedy check containing only HP. During 2018 in all weeds weedy check, maximum HP relative density (33.33%) was observed while in 2019, plot where weeds were controlled from growing till 20 DAE showed (80%) relative density at 30 DAE. HP maximum frequency (66.67%, 77.78%) and relative frequency (66%, 100%) was recorded at 45 DAE in plots where HP was kept controlled till 20 DAE and all weeds kept controlled till 20 DAE, respectively. Maximum number of grains per cob (738, 700.68), 1000 grain weight (306.66, 271.51 g) and grain yield (6150, 8015 kg hec -1 ) were recorded in plots which were kept all weed free till 60 DAE. As the competition period of weeds increased over 40 DAE, it substantially reduced yield of maize. Keeping the plots HP free till 40 DAE in the maize fields with HP as the major dominating weed, likely increase in maize grain yield is up to 30% compared to the fields where HP left un attended throughout the growing season. However, if maize field is infested with a mix of weeds with more than one dominating weeds including HP, compared to weedy situation the whole season, 30% higher grain yield can be obtained if all weeds are kept controlled till 40 DAE. Hence it can be concluded that whether the farmers face heavy HP infestation only or the mix of weeds as dominating weeds, in either case farmer should control weeds within first 40 days in maize field for better grain yield.
