“…The pre-emergent Group B SU herbicides have limited incorporation requirement compared with many other preemergent herbicides, making them eminently suitable for minimum-tillage systems. However, the intensity of SU herbicide use in alkaline soils has historically been influenced by lengthy plant-back periods limiting rotational options, with Group D herbicides a common alternative (Black et al 1999;Boutsalis et al 2006;Nufarm Australia 2018a). This has potentially resulted in the following: higher herbicide resistance in acidic soils due to reduced cultivation associated with Group B herbicide use; lower Group A resistance in alkaline soils because some weed control can be obtained by the cultivation needed for incorporation; and increased Group D resistance in the alkaline soils due to greater selection pressure (Boutsalis et al 2006).…”

Herbicide resistance is a common occurrence in southern Australia. The evolution of herbicide resistance is influenced by the selection pressure placed on the weed species controlled by that herbicide. Results from resistance screening of ~4500 annual ryegrass (Lolium rigidum Gaud.) samples were entered in a GIS database, together with several agricultural parameters used in the Australian Bureau of Statistics Agricultural Surveys. This allowed a study of the associations between mode of action of resistance, geographic distribution of resistance across southern Australia, and farming practices employed in particular regions. Cultivation was negatively associated with resistances in acetyl-CoA carboxylase (ACCase)-inhibiting cyclohexanedione and acetolactate synthase (ALS)-inhibiting herbicides. Higher proportions of wheat sown were associated with higher incidences of resistance. ACCase-inhibiting aryloxyphenoxypropionate and cyclohexanedione and ALS-inhibiting resistances were higher in those shires where soils were predominantly acidic. This study demonstrates the association between farm practice and the evolution of herbicide resistance. The analysis provides reinforcement to the principle of rotating chemical modes of action with non-chemical weed control measures to minimise the risk of herbicide resistance evolution in any farming system.

“…imidazolinones) or alkaline (e.g. sulfonylureas), thereby limiting crop-rotation options (Black et al 1999;Kennedy 2003). Reduced tillage can result in increased soil acidity, enhancing the persistence of some herbicides or limiting crop rotations through the pH level itself (Blevins et al 1983;Locke and Bryson 1997).…”

“…1 Cinosulfuron tion, a very low animal toxicity has been reported (Tomlin 1994). However, depending on environmental conditions, sulfonylureas or their metabolites may persist excessively in the environment with a residual phytotoxicity (Anderson and Humburg 1987;Black et al 1999;Sarmah et al 1999). They can also reach the aquifer (Battaglin et al 2000).…”

The photocatalytic degradation of a sulfonylurea herbicide, cinosulfuron, has been studied in TiO 2 aqueous suspensions. A first order kinetic law was found. The influence of the initial concentration of cinosulfuron and of the initial radiant flux on the kinetics were evaluated. The identification of the intermediate products was based on high performance liquid chromatography coupled with mass spectrometry analyses (HPLC-MS). The mineralization of cinosulfuron was traced using ion chromatography and total organic carbon (TOC) measurements. These results indicate that the photocatalytic degradation of cinosulfuron leads to CO 2 , NO 3 − and SO 4 2− as final products, and in addition cyanuric acid (C 3 H 3 O 3 N 3 ), confirming previous results on triazinic ring-containing compounds.

“…In soils that are neutral to alkaline, they exist as anions and degrade very slowly (Sarmah et al 1998). Black et al (1999) and Hollaway et al (2006) found that most chlorsulfuron residue was located in the top 20 cm of soil. Studies in Queensland reported minimal carry-over of sulphonylureas in alkaline soils in a sub-tropical climate (Walker & Robinson 1996) and indicated that recropping was safe within 1 year of the application of chlorsulfuron (Osten & Walker 1998).…”

The herbicide chlorsulfuron is commonly applied to cereals and may persist in alkaline soil long enough to damage subsequent sensitive crops. Sewage water, a potential source of the heavy metal cadmium (Cd), is used to irrigate agricultural soils in many developing countries. The current work evaluated the effects of the residual herbicide chlorsulfuron and Cd on maize seedlings, with particular attention to the mechanism of their action on plant growth. Maize seeds were planted in soil that had been sprayed with chlorsulfuron and Cd, after which residues in both seedlings and the soil were measured. The chlorsulfuron dose was correlated with the amount of residue found in seedlings but not in the soil. In all, 39 metabolites were identified in seedlings using the Automated Mass spectral Deconvolution and Identification System software program and the retention index method. The combination of chlorsulfuron and Cd significantly reduced multiple metabolites in the shikimate pathway, malic acid and citric acid production in the tricarboxylic acid cycle, and lactic acid, glucose, aspartic acid, asparagine and 3-glycerophosphoric acid production. In addition, chlorsulfuron caused an increase in multiple amino acids, including tyrosine, methionine and asparagine, and a marked decrease in caffeic and cinnamic acids (the secondary metabolites derived from the shikimate pathway and galactose). Finally, chlorsulfuron and Cd stress markedly increased shikimate acid, decreased 3-glycerophosphoric acid and caused negative correlations between the amounts of phenylalanine and tyrosine and those of quinicand cinnamic-acid. In conclusion, chlorsulfuron and Cd did not have a synergistic effect on maize seedlings; rather, the combination of these pollutants had an antagonistic effect on some amino acids.
