Abstract The development of glufosinate-resistant soybean cultivars has created opportunities for use glufosinate applied postemergence weed control. Four field experiments were conducted in 2021 and 2022 to ascertain the effect rate addition ammonium sulfate on annual control glyphosate/glufosinate/2,4-D–resistant soybean. An increased 500 from 300 g ai ha −1 improved common ragweed, lambsquar...

Experiments were conducted in the greenhouse to assess root galling and egg production of three root-knot nematode species, Meloidogyne arenaria, M. incognita, and M. javanica, on several weeds common to Florida agricultural land. Weeds evaluated were Amaranthus retroflexus (redroot pigweed), Cyperus esculentus (yellow nutsedge), Eleusine indica (goosegrass), Portulaca oleracea (common purslane...

A two year field experiment was carried out to evaluate the effects of municipal waste compost (C), composted cattle manure (M), and nitrogen (N) on growth and composition of weeds in a corn field in Shiraz using a split-split plot design with 3 replicates. Visual inspection of the plots showed that the manure treatments neither introduced new weed species nor increased weed density more than t...

allelopathic plants, because of reduction in herbicide uses, are important in weed management. the allelopathic effects of sage salvia officinalis and white wormwood artemisia sieberi water extract were evaluated on germination and seedling growth of redroot pigweed amaranthus retroflexus at concentration of 0, 5, 10, 15, and 20% in controlled conditions. anova revealed that the extract concent...

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 vari...

abstract recently weed scientist are more interested in weed management by allelopathy . the main objective of the study was to evaluate allelopathic potential of sunflower on redroot pigweed and common lambsquarter. this study was conducted in two series of laboratory and greenhouse experiments. under laboratory conditions, leaf, stem and root aqueous extracts of sunflower at 0%, 2.5%, 5%, 7.5...
