Special Issue Information

Dear Colleagues,

Anthropogenic activities have led to severe climatic changes that have critically impacted all aspects of life, with serious implications for crop production and protection. Although some benefits for crop production are hinted at, climate change is expected to negatively affect  factors involved in crop protection, including weed biology, herbicide efficacy and the sustainability of weed management. Hence, this Special Issue intends to explore the consequences of climatic changes on the abovementioned topics.

In addition to research on the effect of shifting climate conditions on herbicide properties, studies proposing methods to achieve sustainable weed control under a changing climate are welcomed for this Special Issue.

Suitable topics for this Special Issue could include:

  • Impact of climate change on herbicide properties;
  • Impact of climatic change on weed growth;
  • Impact of climatic change on herbicide efficacy;
  • How climate change affects the sustainability of weed management;
  • Studies proposing methods to achieve sustainable weed control under a changing climate.

Weed management is a crucial aspect of sustainable agriculture. In this study, we investigated the allelopathic potential of wedelia (Wedelia trilobata L.) leaf extract as a bioherbicide against purple nutsedge (Cyperus rotundus L.). The experiments were carried out through greenhouse experiments using a completely randomized design (CRD) with four replications. Five different concentrations were evaluated: C10% (10% wedelia extract concentration), C20% (20% wedelia extract concentration), C40% (40% wedelia extract concentration), C+ (92 mg L−1 of gallic acid), and C− (aquadest). Allelochemicals present in the wedelia leaf extract inhibited plant height, shoot number, leaf number, leaf area, root area, and total root length. The fresh weight, dry weight, and photosynthetic pigments decreased with increasing wedelia leaf extract concentrations. Malondialdehyde contents were highest when C40% was used. Additionally, peroxide activities decreased at the highest wedelia leaf extract concentration, indicating the failure of the plant’s antioxidant defense mechanism. The decrease in growth, photosynthetic pigment, and antioxidant activity indicates that wedelia leaf extract may be able to help control the growth of purple nutsedge. The results of this study could contribute to the development of a new cropping system based on the use of wedelia as a bioherbicide for sustainable agriculture. Full article

A long-term, sustainable solution to weed infestation is extremely desirable because weeds have the potential to reduce crop productivity and the aesthetic appeal of the environment. In this study, the impacts of mowing and varying degrees of trampling pressure on the suppression of weeds, alongside wound-induced changes in the allelopathic potential, of the rhizosphere soil and the root exudates of southern crabgrass (Digitaria ciliaris) and Asian flatsedge (Cyperus microiria) were evaluated under both field and greenhouse conditions. The field study results showed that all trampling treatments induced the relative suppression of weed growth. Grass weeds showed higher resistance to trampling than broad-leaved weeds. However, laboratory bioassays showed that light trampling caused a significant increase in the growth-inhibitory effects of southern crabgrass rhizosphere soil on lettuce. Moreover, mowing (9.11% of control) and trampling (16.4% of control) resulted in a marginal increase in the growth-inhibitory effects of root exudates released from southern crabgrass. Furthermore, the growth-inhibitory activities of the Asian flatsedge rhizosphere soil were significantly reduced after heavy trampling pressure. Moreover, mowing and trampling resulted in marginal reductions in the growth-inhibitory activities of root exudates released from Asian flatsedge against lettuce (i.e., 18.7% and 28.5%, respectively). In general, mowing and varying degrees of trampling induced contrasting and integrated impacts on weed suppression as well as the allelopathic potential of both southern crabgrass and Asian flatsedge.

Narrow row spacing has attracted significant attention due to its beneficial impacts on weed management in cotton. This study compared the effects of normal and ultra-narrow row spacing on critical periods of weed control in American (Gossypium hirsutum L.) and ‘Desi’ (Gossypium arboreum) cotton. Two different row spacings (i.e., recommended (75 cm) and ultra-narrow (30 cm)) and three weed control intervals (i.e., weed control at 30, 60 and 90 days after sowing (DAS)) were included in the study. Weedy-check and weed-free treatments were included in the experiment as controls for comparison. ‘Desi’ cotton grown under ultra-narrow spacing recorded the lowest weed density and individual density of Trianthema portulacastarum L., Cyperus rotundus L., Cynodon dactylon L., Echinochloa colona (L.) Link and Digera muricata (L.) Mart. Moreover, ‘Desi’ cotton sown under ultra-narrow spacing with weed-free and weed control at 30 DAS resulted in the highest leaf area index (LAI), leaf area duration (LAD), net assimilation late (NAR), root elongation rate (RER) and root growth rate (RGR) at all sampling dates. Likewise, ‘desi’ cotton sown under recommended row spacing and weed-free conditions produced the highest number of sympodial and monopodial branches, number of flowers and bolls per plant, whereas the highest seed cotton yield of ‘Desi’ cotton was noted under ultra-narrow spacing and weed-free conditions. It is concluded that sowing both cotton types in ultra-narrow row spacing and controlling weeds at 30 DAS will result in lower weed infestation and higher seed cotton yield. Full article
