Product Information

Quite rightly, Fusarium risk often drives T3 fungicide decisions. This clearly remains extremely important given mycotoxin risks from Fusarium. As well as choosing an appropriate Fusarium-active fungicide and applying it at a suitable dose, achieving the correct spray timing (GS63-65) is critical when targeting Fusarium. Prothioconazole is likely to remain a key component in barley fungicide programmes. Elatus Era contains prothioconazole, co-formulated with the SDHI fungicide, solatenol, for long-lasting protection. If used solo, apply SDHI fungicides in strict alternation with fungicides from adifferent cross-resistance group.

At T2 the canopy is complete, and growers can take advantage of the long-lasting disease control. The top leaf layer is also crucial to protect in wheat, contributing the largest amount to yield. In lower disease risk situations or in later-drilled crops in England, it may be possible to apply a single fungicide spray in spring barley, typically at GS37-45, rather than a T1 plus T2 programme. However, the most complete protection will come from two sprays, and this may be preferred in Scotland where the growing season is longer.

Curr Opin Genet Dev 35:57–65 That performance is reflected in trials from 2016 to the current day. AICC regional trials have shown Ascra’s protective properties to be on a par with Revystar and Univoq, only when exposed to curative pressure are differences seen – and then only small. The adverse effects of boscalid on CNS development and functioning were investigated in two recent studies. First, Wang et al. [ 39] showed that embryos exposed for 48 h to boscalid at 14.56 µM and above displayed gross brain defects, including decreased number of newborn neurons, enlarged brain ventricles, and reduced number of spontaneous movements. In addition, 6 dpf larvae exposed for 24 h to boscalid at 14.56 µM displayed markedly decreased locomotion. Using environmentally relevant concentrations, Qian et al. [ 31] found that larvae exposed for 7 days to boscalid at 0.87 and 1.74 µM showed significant inhibition of locomotor abilities and reduced phototactic response, respectively. Following 4 or 8 days of exposure to boscalid at 1.74 µM, larvae also showed decreased AChE activity and defects in cerebellar granule cell and retina neuron differentiation. Long-term toxicity studies (21 days) of boscalid toward adults indicated that exposure to 2.9 µM caused significant inhibition in average velocity and acceleration, but a significant increase in active time and distance moved, and exposure to 0.029 µM markedly impaired predatory abilities. Lastly, transcriptome analysis indicated changes in the expression of genes related to neurodevelopment in embryos exposed to bixafen at 1.74 µM for 96 h or 0.87 µM for 8 days, with downregulation of mbp and synapsinIIa, and upregulation of gap43. In addition, several genes required for eye development and phototransduction, opn1sw1, opn1mw1, opn4.1, and rho, were significantly upregulated following exposure to 0.87 µM boscalid for 8 days but downregulated with higher concentrations (3.49 µM). Exposure to subacute doses of boscalid thus impaired several essential neuro-behavioral processes, locomotion, and the ability to detect prey, possibly caused by visual system defects and a severe reduction in cerebellar granule cells.A. The second generation SDHIs have been likened to having the impact of strobilurin fungicides when they were first launched. For example, yield responses in wheat trials with a full rate of Aviator Xpro averaged 0.6t/ha over current standards in 2008 and 2009. In barley Siltra Xpro yielded 0.25t/ha more than Fandango on average in the same years. Neither firm is particularly pushing growers to use the product at T1, although in high early septoria pressure situations there could be a case for considering it. However, neither has much eyespot activity, and if that is a strong driver at that timing, another option could be better. The SDHI that has been most thoroughly studied for long-term toxicity in adult zebrafish is thifluzamide. Yang et al. [ 23] first showed that following exposure to thifluzamide at 0.36 µM for 21 days, liver damage could be observed, including hepatocyte vacuolization and necrosis. In addition, decreased mitochondrial enzymatic activities were detected in adults exposed for 28 days to thifluzamide at 0.36 µM, including SDH and all four ETC complexes, and exposure to 0.036 µM significantly affected mitochondrion morphology and inhibited ETC complexes III and IV. Lastly, gene expression analysis indicated that thifluzamide at 0.036 µM and above caused decreased expression of immunity-related genes il-8 and ifn and two chemokine-encoding genes. Thifluzamide at 0.036 µM also induced upregulation of pro-apoptotic genes p53, casp-3, and apaf1, but higher doses (0.36 µM and above) induced markedly decreased expression of these genes and of bcl-2 and casp-9. This study produced the first evidence that long-term exposure to low doses of thifluzamide causes severe adverse effects related to mitochondrion defects and subsequent apoptosis. Using the same 28-day exposure protocol, Yang et al. [ 34, 35] further investigated the long-term adverse effects of thifluzamide with a focus on liver toxicity, glycometabolism, energy production, and lipid metabolism. Thifluzamide at 3.6 µM caused a significant increase in liver glycogen content and glucose-6-phosphate dehydrogenase (G6PDH) activity, associated with a marked decrease in blood glucose concentration and lactate dehydrogenase (LDH) activity. Pyruvate accumulation was also significantly decreased following exposure to thifluzamide at 0.36 µM. Gene expression analysis indicated that genes required for mtDNA replication and transcription, polg1, twk, tk2, polmt, tfam, and mt-nd1, were downregulated, and sdha was upregulated, following exposure to 0.036 µM thifluzamide; the expression of genes encoding ETC proteins, ndufs4, sdha, uqcrc2, cox5ab, and atp5α 1, was significantly decreased in individuals exposed to 0.36 µM and above. Analysis of liver lipids revealed that thifluzamide decreased triglycerides (0.036 µM and above) and total cholesterol (0.36 µM and above). Also, fatty acid synthase (FAS) and carnitine palmitoyl transferase (CPT-1) activities were markedly decreased (0.36 µM). Importantly, hepatocyte damage was also observed (0.036 µM), including swollen endoplasmic reticulum (ER) and stripped ribosomes. Additionally, several genes related to lipid metabolism were markedly downregulated following exposure to thifluzamide at 0.036 ( prl, dgat1b, mgst1, insr, and ngf) and 0.36 µM ( xdh), while ide expression was significantly decreased in the two groups.

was another year of unseasonal weather, with a mostly cool dry spring giving way to warm and wet weather later – ideal Septoria conditions. Compounded by delayed leaf emergence and stretched spray timings, wheat crops came under intense late disease pressure.Syngenta has not released pricing for its new wheat product, but, assuming approval is given, expect to pay a similar amount. A. Both firms are targeting the new wheat products firmly at the T2 flag leaf market. Neither is particularly systemic, meaning they won’t move to new growth, but they are long-lasting and give excellent disease control. It could be particularly relevant if fungicides with reduced rust activity were used earlier in the programme and/or if T2 was applied early and there is a risk of it ‘running out of steam’. To help gain a better understanding of thifluzamide hepatotoxicity and the associated toxic mechanisms, Yang et al. [ 35] studied the effects of thifluzamide on the expression of genes related to hepatocyte physiology, unfolded protein response (UPR), and autophagy. The data showed that thifluzamide at 0.036 and 0.36 µM induced marked downregulation of hepatocyte-specific ( hpx, cyp3A4, and ces2) and UPR genes ( atf6, ire1α, xbp1, perk, bip and atf4), associated with increased expression of autophagy-related genes lc3 (0.036 µM and above) and beclin and agt-5 (0.36 µM). In addition, autophagic features in hepatocytes, but decreased caspase-3 activity, were observed following exposure to thifluzamide at 0.036 µM and above. These data suggest that oxidative stress and autophagy, along with ER stress, but not apoptosis, play an important role in the hepatotoxicity of thifluzamide in zebrafish. The acute toxicity to adult zebrafish of thifluzamide, flutolanil, and fluxapyroxad also enabled a comparison of the LC 50 values with those observed for other adult fish species. The results show that the most sensitive species varies according to the SDHI studied. For example, bluegill ( Lepomis macrochirus) was more sensitive to thifluzamide (96 h LC 50 2.46 µM) than zebrafish (96 h LC 50 7.93 µM), but less sensitive to flutolanil (96 h LC 50 16.7 µM) than zebrafish (96 h LC 50 8.35 µM). Another example was fluxapyroxad, for which the 96 h LC 50 value was 0.76 µM for common carp and 3.02 µM for bluegill. By contrast, the 96 h LC 50 values of fluxapyroxad were close for adult zebrafish and bluegill (2.4 µM, and 3.02 µM, respectively).
