“…There was little difference between the effectiveness of the wetter and the adjuvant. This is in contrast to the results obtained by Last and Bean (1991) who showed increased uptake of Mn (when applied as sulphate or as an inorganic formulation) when an adjuvant was used in the spray. The reason for the different effects of the adjuvant with Cu and Mn is not known.…”

“…The foliar sprays of both forms of Cu also contained either Agral, a non-ionic wetting agent or LZ700 containing wetting agents and penetrants. Previous work had shown this adjuvant to increase uptake of foliar applied Mn by sugar beet (Last and Bean 1991). The Agral was used at a rate of 0-1 ml litre-' and the LZ700 at a rate of 5 ml litre-'.…”

Previous studies have shown positive yield responses from foliar copper (Cu) applications to beet. However, some of these responses may have been due to fungicidal instead of nutritional effects. Also, since these studies, national yields have increased possibly increasing the Cu requirement of the beet crop. So, between 1987 and 1990 six field experiments tested the effect of foliar sprays of copper on the yield and processing quality of sugar beet. The copper was applied as Cu oxychloride or an inorganic Cu formulation, in factorial combination with a wetter or an adjuvant. Four of the experiments were on loamy sand textured soils, the remainder on peaty soils. The Cu sprays did not affect beet yields for crops grown on the peat soils. On two of the light textured mineral soils the Cu sprays did increase yield, but there was no clear relationship between soil ethylene diamine tetra acetic acid (EDTA) extractable Cu and yield response to added Cu. There was little difference between the forms of Cu tested on yield, or between the wetter or the adjuvant. Cu sprays did not affect beet processing quality, even when large yield responses were obtained. An analysis of the geographical distribution of sugar beet quota and soil extractable Cu showed that 15% of the UK's national crop could be affected by Cu deficiency.

Zinc is an essential microelement, but its excess exerts toxic effects in plants. Heavy metal stress can alter the metabolism of reactive oxygen (ROS) and nitrogen species (RNS) leading to oxidative and nitrosative damages; although the participation of these processes in Zn toxicity and tolerance is not yet known. Therefore this study aimed to evaluate the zinc tolerance of Brassica organs and the putative correspondence of it with protein nitration as a relevant marker for nitrosative stress. Both examined Brassica species (B. juncea and B. napus) proved to be moderate Zn accumulators; however B. napus accumulated more from this metal in its organs. The zinc-induced damages (growth diminution, altered morphology, necrosis, chlorosis, and the decrease of photosynthetic activity) were slighter in the shoot system of B. napus than in B. juncea. The relative zinc tolerance of B. napus shoot was accompanied by moderate changes of the nitration pattern. In contrast, the root system of B. napus suffered more severe damages (growth reduction, altered morphology, viability loss) and slighter increase in nitration level compared to B. juncea. Based on these, the organs of Brassica species reacted differentially to excess zinc, since in the shoot system modification of the nitration pattern occurred (with newly appeared nitrated protein bands), while in the roots, a general increment in the nitroproteome could be observed (the intensification of the same protein bands being present in the control samples). It can be assumed that the significant alteration of nitration pattern is coupled with enhanced zinc sensitivity of the Brassica shoot system and the general intensification of protein nitration in the roots is attached to relative zinc endurance.

“…32 MnSO 4 was also more effective than Mn-EDTA to increase leaf Mn concentration in orange trees 33 and sugar beet. 34 The reduced Mn content in the petioles in plants treated with Mn-EDTA could be associated with a negative net charge of the complex, since the cuticle itself is negatively charged. 1,32 By analogy with zinc complexes, 35 one can expect the diffusion coefficient of Mn-EDTA to be about half of that of MnSO 4 .…”

Increasing the yield of soybean is a challenge to humankind dependent on several management practices, such as fertilizing and weed control. While glyphosate contributes to controlling weeds, it can interfere with spray mixture stability and, supposedly, complex with micronutrients within the plant tissue. This study investigated the effects of glyphosate on soybean foliar uptake and transport of Mn supplied as MnSO4, MnHPO3, Mn-ethylenediamine tetraacetic acid (EDTA), and MnCO3. These fertilizers induced ultrastructural changes in the leaf cuticle, regardless of the glyphosate mixture. Except for MnCO3, all tested sources increased the Mn content in the petiole. The mixture of glyphosate impaired Mn transport from MnSO4 and MnHPO3, but no evidence of Mn–glyphosate complexation within the plant was found. Manganese is rather transported in a similar chemical environment regardless of the source, except for Mn-EDTA, which was absorbed and transported in its pristine form. Interferences of glyphosate seem to be related to complexations in the tank mixture rather than affecting nutrients’ metabolism.
