Applicator exposure to 2,4‐D, dicamba, and a dicamba isomer
Journal of Environmental Science and Health - Part B Pesticides, Food Contaminants, and Agricultural Wastes, 1982Potential respiratory and dermal exposure to applicators were estimated in a ground boom spray application of 2,4-D and dicamba. Time-weighted averages for airborne herbicide residues did not exceed 2.2 microgram/cu.m. in the cabs of application vehicles allowing only minor respiratory exposure. Dermal exposure was important as relatively large amounts

Factors influencing dicamba drift, especially vapor drift, were examined in field and growth chamber studies. In field experiments, potted soybeans[Glycine max(L.) Merr.]. exposed to vapors arising from corn (Zea maysL.) foliarly treated with the sodium (Na), dimethylamine (DMA), diethanolamine (DEOA), orN-tallow-N,N1,N1-trimethyl-1,3-diaminopropane ...

Differentially expressed genes in dicamba‐resistant and dicamba‐susceptible biotypes
Weed Biology and Management, 2011In an ongoing effort to investigate the mechanism of auxinic herbicide resistance in Kochia scoparia (kochia), polymerase chain reaction‐based cDNA suppression subtractive hybridization was used to identify genes that are differentially expressed between dicamba‐resistant (HRd) and dicamba‐susceptible (S1) kochia biotypes in response to herbicide ...

Herbicides are standard weed management tools for producers. This lesson examines the development of herbicide resistant-weeds and research conducted to help predict and prevent this resistance. Discussion on populations of organisms and evolution of these populations is included.

Use of dicamba-degrading microorganisms to protect dicamba susceptible plant species
Journal of Agricultural and Food Chemistry, 1991Three strains of dicamba-degrading microorganisms were able to reduce the herbicidal activity of dicamba in the rhizosphere quickly enough to allow dicamba susceptible crop species to grow. Pea seedlings planted immediately after inoculation had higher weights over the uninoculated controls at the 0.5 and 4.0 lb/acre rates in growth chamber studies (.)

Abstract Chenopodium album is a troublesome arable weed species which has evolved resistance to dicamba in New Zealand. The objective of this work was to investigate the patterns of absorption, translocation and metabolism of dicamba in resistant and susceptible C. album populations.

AbstractDicamba (3,6‐dichloro‐2‐methoxybenzoic acid) effectively controls many dicotyledonous weeds, but nontarget species such as soybean [Glycine max (L.) Merrill) are susceptible to spray or vapor drift. Field studies were conducted on a Canfield silt loam (fineloamy, mixed, mesic Aquic Fragiudalf) soil to determine the response of ‘Elf’ and ...

Abstract Kochia plants resistant (R) to field rates of dicamba were characterized for their frequency of occurrence and levels of resistance and for the physiological fate of applied 14C-dicamba. Of 167 randomly sampled fields and seven fields identified by producers to contain R kochia, 19 contained plants that produced 1% or more R progeny.

Dissipation and Phytotoxicity of Dicamba
Weed Science, 1969Dissipation of 2-methoxy-3,6-dichlorobenzoic acid (dicamba) was greater in Sharpsburg silty clay loam soil than in Anselmo sandy loam soil and was faster in the topsoil than in the subsoil. Breakdown increased with increasing soil incubation temperatures.

Dicamba is a semivolatile herbicide that has caused widespread unintentional damage to vegetation due to its volatilization from genetically engineered dicamba-tolerant crops. Strategies to reduce dicamba volatilization rely on the use of formulations containing amines, which deprotonate dicamba to generate a nonvolatile anion in aqueous solution ...
