Specialty crop sensitivity to dicamba
… to 47% in 2019 (USDA-NASS). During this time, dicamba (2-methoxy-3,6-dichlorobenzoic acid) tolerant soybeans (Glycine max) and cotton (Gossypium hirsutum) were first introduced (2017) and approximately 1.45 million hectares of soybean were injured by the off-target movement of dicamba across …

Dicamba Effects on Soybean (Glycine max) Growth, Yield, and Offspring
<p>Introduction of a new dicamba-resistant (Xtend) trait in soybean and cotton will increase dicamba herbicide use. Consequently, concern for injury to sensitive crops from off-target movement and tank contamination will likely increase. For soybean, foliar symptoms associated with dicamba damage …

Biodegradability of dicamba and 2,4-D in riparian wetland soils
A general review of soils in Virginia counties bordering the Chesapeake Bay reveals that coastal plain soils, especially those most agriculturally productive, are dominantly sandy texture in the subsurface horizon, and have shallow water tables. Considering the high amounts of pesticides used in …

Response of Grapes to 2,4-D, Dicamba, and Glyphosate Simulated Drift
… New technologies, including 2,4-D and dicamba resistant crops, are one approach for corn and soybean farmers to better manage weeds; however, vapor or particle drift of these herbicides can damage sensitive crops such as grapes, tomatoes, and peppers. Research over the last 30 or more …

Biodegradation of pesticide and indolic compounds under methanogenic conditions
Degradability of atrazine, cyanazine, and dicamba under methanogenic conditions was evaluated using serum bottle microcosms containing wetland soil inocula obtained from three different sites. Pesticides were monitored by high-performance liquid chromatography (HPLC) and the production of methane …

Evaluation of herbicides for no-till corn establishment
… with 2,4-D [(2,4-dichlorophenoxy)acetic acid] or dicamba (3,6-dichloro-2-methoxybenzoic acid) at three timings of application. Both locations were heavily infested with annual, biennial, and perennial broadleaf weeds, including horseweed (Conyza canadensis), buckhorn plantain (Plantago …

THE INFLUENCE OF CARRIER WATER QUALITY, COAPPLIED FOLIAR FERTILIZER, AND WATER CONDITIONING ADJUVANT ON HERBICIDE EFFICACY
… such as ammonium sulfate (AMS). At present, dicamba or 2,4-D resistant crops have been developed and the newer formulation of dicamba or 2,4-D and their premixed formulation with glyphosate will be applied on these crop systems. Likewise, hydroxyphenylpyruvate dioxygenase (HPPD); or …

Isolation and Partial Characterization of a Pseudomonas Species That Degrades 3,6-Dichloro-2-Methoxybenzoic Acid (Analog Enrichment)
… of utilizing 3-6-dichloro-2-methoxybenzoic acid (Dicamba) as a growth substrate could be isolated from an agricultural soil. Secondly, an assessment was made of the role of plasmid DNA in Dicamba degradation.

Alternative Herbicide Control Options for Glyphosate-Resistant Palmer Amaranth (Amaranthus Palmeri)
… efficacy of glufosinate, tembotrione, 2,4-D or dicamba, applied alone or tank-mixed, on Palmer amaranth with higher tolerance to glufosinate in the greenhouse and corn field, and (3) establish the mechanism involved in the tolerance of Palmer amaranth to glufosinate. Tembotrione, 2,4-D, dicamba, …

Control and Fecundity of Palmer Amaranth (Amaranthus palmeri) and Common Ragweed (Ambrosia artemisiifolia) from Soybean Herbicides Applied at Various Growth and Development Stages
… respectively, versus using one SOA (mesotrione, dicamba, 2,4-D, or glufosinate alone). Seed production of 5 to 10 cm Palmer amaranth and common ragweed was reduced greater than 76% by fomesafen, auxin (dicamba and 2,4-D), or glufosinate containing treatments. Some weeds survived and set seed even …

New Herbicide Strategies for Weed Management in Pumpkin and Soybean and Potato Vine Desiccation
… and ALS- resistant biotypes, fomesafen plus dicamba were applied at first postemergence (POST) to small Palmer amaranth (<5 cm, 0 d) and at simulated delays of 7, 14, 21, and 28 d. All plots received lactofen plus dicamba 14 days after first POST. Palmer amaranth control 14 days after first …
