The ability of certain plant species to affect other plants has been well documented since antiquity. The first writings on this subject are attributed to Theophrastus (300 BC), a student of Aristotle who noticed the harmful effects of cabbage on a vine crop and suggested that such effects were caused by "smells" from cabbage plants. This phenomenon of interference among neighboring plants is known as allelopathy and typically includes the study of interactions between plants or plants and microbes, as well as the effects of compounds or allelochemicals released by plants on plant growth or other soil factors and can be studied at different scales within plant communities.
Allelopathic interference is mediated typically by the release of plant or microbially produced secondary metabolites into the environment via volatilization, leaching through rainfall, root exudation or decomposition of plant litter. A single compound or mixture of metabolites may prove to be active but the phenomenon of allelopathy is dependent on the accumulated concentration of bioactive compounds and their persistence over time in the natural environment. Therefore, the study of the ecology of such interactions, as well as the physiology and chemistry of allelochemical interference is critical to the field of allelopathy. Involvement of allelopathic mechanisms in vegetation dynamics and the spatial distribution of plants has been explored to date on a limited basis, both in natural ecosystems or agrosystems. In addition to the fundamental aspects of research on plant interference and relationships between plant species, the field of allelopathy also includes applied aspects of plant ecology including but not limited to, weed and crop ecology and invasive weed management. Aspects of phytoremediation and bioremediation may also be presented in this special issue as well as the development of novel bioherbicides or competitive crops through allelopathy.

Abstract: The present study aims to identify tomato (Solanum lycopersicum L.) cultivars with weed-suppressive ability against target weed species in tomato growing season. Thus, a greenhouse study was conducted at Mississippi State University, at the R. R. Foil Plant Science Research Center, Starkville, MS. Three weed species were targeted: Palmer amaranth (Amaranthus palmeri S. Wats), yellow nutsedge (Cyperus esculentus L.), and large crabgrass (Digitaria sanguinalis L.). Tomato plants and weed species were grown in the same pot. Tomato seeds were sown on the circumference of the pot, and weed seeds were sown in the center of the pot. The four central weed plants in each pot were considered for the evaluations. Four weed-only pots were used as control. The experiment was laid out in a completely randomized design with 17 tomato varieties and a weedy check. The experiment had four replication and was repeated twice. Plant height, chlorophyll, and dry weight biomass of the weeds were measured 28 days after sowing. Cultivar 15 showed the most inhibition in Palmer amaranth seedlings. In the presence of this cultivar, Palmer amaranth height, chlorophyll, and dry shoot biomass were reduced by 58, 28, and 83%, respectively. Chlorophyll percentage in yellow nutsedge seedlings was suppressed by 15% with cultivar 64, whereas 13% of its height was reduced by cultivar 20. Inhibitory effects of cultivar 15 were observed in relation to the total dry biomass of yellow nutsedge, which decreased by 40% in the presence of this cultivar. The percentage of chlorophyll in large crabgrass was reduced by 22% with cultivar 5, whereas cultivar 38 reduced 35% of the seedling height. There was a 44% increase in the biomass reduction of large crabgrass in response to cultivar 63. These results suggest that the weed-suppressive potential of tomato differed among cultivars and weed species. Overall, cultivar 15 was most competitive against the weeds tested and may be used as an effective tool in the suppression of troublesome weeds in tomato.
