“…At present, commonly controlling weeds and management strategy including agricultural and chemical methods, such as mechanical/manual removal, spray chemicals while suppressed by high investment and poor durability [4][5][6]. Although chemical herbicides have better effectiveness such as spray of glyphosate was well control weed growth at short time, while the effectiveness will reduced when longtime applied owing to rapidly developing of weed resistance biotypes [7][8][9]. In addition, chemical herbicide and pesticide residues was hard to degrade and cause harmful effect on organisms and environmental from contamination of water and land as well as gases [10][11][12].…”

In order to isolated and identified the bacterial strains from wheat rhizosphere and evaluated the effect of different concentration of bacterial fermentation broth on the wild oats weed growth. This experiment carried out the separation and purification of dominant bacterial strains from the wheat rhizosphere soil, and performed the fermentation broth biological activity assessment by measured the seed germination and plant growth from 20 wheat varieties. The results had shown that the bacterial fermentation broth inhibits the growth of wild oat seedlings and plants to varying degrees, bacterial strains of X3, X4, X8, X12, X16 and X20 has certain level of inhibition activity and X20 has the highest herbicidal effectiveness. According to molecular biology identification, obtained superior bacterial strains X20 was Bacillus as potentially inhibitor for developing of bacterial-based bioherbicides for wild oats weed control management in the wheat field.

“…Overall, the effect of AM fungal taxa on weed growth seems to be not easily predictable. Concerning maize production, Li et al (2019) [ 18 ] found that the effect of AM inoculants on weeds and maize growth varied greatly across plant species. Numerous AM taxa were shown to have negative effects on certain weeds but not on maize.…”

Weeds: An Insidious Enemy or a Tool to Boost Mycorrhization in Cropping Systems?

Weeds have always been considered an insidious enemy, capable of reducing crop production. Conversely, the agroecological vision attributes a key role to the spontaneous flora in promoting plant diversity and belowground interactions, which may improve the ecological performance of agroecosystems. We summarized the literature on the weeds’ arbuscular–mycorrhizae (AM) interaction and we analyzed evidence on the: (i) AM suppressive/selective effect on weed communities; (ii) effect of weeds on AM colonization, and (iii) positive role of AM-supporting weeds on forming shared mycorrhizal hyphal connections in agroecosystems. While some authors conceptualized AM as a weed control tool, others underlined their selective effect on weed communities. Recent studies suggest that AM-host weeds can participate in the development of a common mycorrhizal mycelial network (MMN) among different plants species. Nevertheless, direct evidence of the actual exchange of nutrients and C between coexisting plants through MMN in agroecosystems is missing. Although the effect of agricultural practices on plant community-AM interactions are complex, more conservative farming management seems to foster AM populations. Future studies should focus on: (i) field studies, (ii) weed communities and their traits, rather than on the most abundant species, and (iii) the use of advanced analytical techniques, able to monitor MMN development and functionality.

“…Todavia, algumas medidas de controle possuem custo elevado e pouca durabilidade, como: capina manual que necessita de muita mão-de-obra, mas possui baixo rendimento operacional (LAZARUS et al, 2020). No entanto, o controle químico tem sido uma das ferramentas mais utilizada no manejo de plantas daninhas, principalmente em sistemas de cultivos convencionais, mas não é recomendado a adoção deste método como única ferramenta de controle, pois pode aumentar a pressão de seleção de biótipos resistentes a herbicidas (LI, et al, 2019). Ainda mais, algumas moléculas de herbicidas possuem degradação lenta no ambiente; dependendo das propriedades físico-químicas, podem lixiviar para camadas mais profundas do solo, o que pode contaminar os lençóis freáticos e consequentemente causar poluição ambiental (CARVALHO, 2013).…”
