Evaluation of Anaerobic Soil Disinfestation for Environmentally Sustainable Weed Management

In anaerobic soil disinfestation (ASD), amended with a carbon source undergoes conditions accompanied by changes in microbial community composition and an increase the concentration of organic acids, primarily acetic butyric gases that are deleterious to plant pathogens, insects, potentially weeds. The purpose this study was explore efficacy ASD different sources on inactivation propagules variety weed species. Germination viability common lambsquarters (Chenopodium album L.), black nightshade (Solanum nigrum yellow nutsedge (Cyperus esculentus pokeweed (Phytolacca decandra barnyardgrass (Echinochloa crus-galli dandelion (Taraxacum officinale (Weber)), redroot pigweed (Amaranthus retroflexus L.) were tested using rates four sources: molasses, wheat bran, mustard greens biomass, raw chicken manure. Wheat bran most effective for all propagules, followed molasses biomass. Carbon mixed soil, which irrigated saturation covered plastic promote three weeks. Chicken manure inactivated species except A. compared control. Rates applied weakly but significantly correlated (r > 0.42 p < 0.04) seed mortality or germination inhibition (E. crus-galli) C. album, retroflexus, S. nigrum. Laboratory tests confirm acid toxicity showed 1000 µL L−1 plus acids at least 60 h inhibited sprouting tubers E. crusgalli seeds, whereas 120 exposure required inhibit germination. Anaerobic effectively suppressed when biomass used as sources. This approach could be adopted management systems any farming system where priority is given environmentally sustainable practices.
