A new study has shown that turf algae release chemicals that can kill young kelp, creating a feedback loop that reinforces kelp forest collapse. The research reveals an indirect way climate change is reshaping ocean ecosystems, complicating kelp forest recovery along Maine's rapidly warming coast.
Studies show that some allelopathic winter cover crops may impact row crop yields, with corn and wheat affected by cereal rye chemicals. However, clear cause-and-effect relationships are rare due to limited field studies.
A new study has found that crabgrass produces chemicals that inhibit the growth of nearby staple crops like wheat, corn, and soybeans. The research, published in ACS' Journal of Agricultural and Food Chemistry, suggests that crabgrass is not just a nuisance but also a significant cause of crop loss on farms.
Researchers evaluated rice varieties for their allelopathic potential, finding that certain parts of the plant can inhibit barnyardgrass growth. This study suggests the possibility of developing rice-based natural herbicides to improve weed control.
