Remember, azoxystrobin acts against the fungus the same way as trifloxystrobin does and so on. Strobilurins present broad-spectrum, rapid and highly efficient germicidal activities, are cost effective and rapidly degrade during plant metabolism, and these benefits have contributed to the large-scale use of these fungicides.

This also includes pre-mixes such as Adament which have a strobilurin component. Additionally, as the degradation of contaminants by microorganisms is a slow process, more details about strobilurin biodegradation pathways, degradation enzymes and genes that encode for key enzymes will help to identify the new bioremediation strategies.

Caution must be taken when applying these products in the vicinity of sensitive crops. In berries, they are especially effective against fruit rot and foliar fungi.

Strobilurin residues have increased in trophic level due to biomagnification; thus, the development of degradation technologies for these pesticides is necessary. The threat for resistance development in important pathogens to FRAC group 11 fungicides is always present, and it will become even more important to monitor as generic products with azoyxstrobin and other group 11 fungicides as active ingredients begin to emerge in the future.

Four species of Bacillus spp. Environmental concentrations of azoxystrobin higher than the Regulatory Acceptable Concentration (RAC) have been found in ecosystems, which poses a serious risk to soil organisms, aquatic organisms, and mammals (Warming et al., 2009; Dijksterhuis et al., 2011; Liu et al., 2013; Mostafalou and Abdollahi, 2013; Rodrigues et al., 2013; Regueiro et al., 2015; Li et al., 2016; Pearson et al., 2016; Zubrod et al., 2019). Although highly effective, fungicide chemistries like those in FRAC group 11, with a very specific MOA, are susceptible to fungicide resistance development by some fungi. In the 2015 Vegetable Crops Recommendations Guide you will see that most references to Quadris have been replaced with azoxystrobin, much like we did the chlorothalonil (i.e., Bravo Weatherstik) a few years ago. The results highlighted the genotoxic threat to freshwater fish in azoxystrobin-contaminated rivers (Bony et al., 2008). Chemosphere 68, 12801288. Microbiol. It is advisable to alternate strobilurins with block treatments (2 to 3 sprays) of fungicides with a different mode of action, including multi-site contact materials that have a low risk of resistance development, such as Bravo, Captan, and Ziram, or biological control agents, such as Serenade. 30, 6774. Tank-mixing strobilurins with other fungicides is usually not necessary or cost-effective since they already have a broad spectrum of activity. 271, 22642271. Strobilurin resistance has been reported in grapevine powdery and downy mildew in various eastern US states and has not also been confirmed in grapevine powdery mildew in Michigan.

(2018) also investigated the effects of azoxystrobin and picoxystrobin on the embryonic development and enzyme activity of zebrafish (Danio rerio). Though the structures of strobilurins were complex due to many active sites on its molecular, the possible molecular mechanisms involved in strobilurin biodegradation pathways were similar (Balba, 2007; Chen et al., 2018; Wang et al., 2018).

In the strobilurins, a single nucleotide polymorphism of the cytochrome b gene leads to an amino acid substitution of glycine with alanine at position 143 of the cytochrome b protein.

To do this, it is important to limit the number of strobilurin applications, for instance by alternating them with fungicides with a different mode of action. Strobilurin fungicides are globally used to combat white mold, rot, early and late leaf spot, rusts and rice blast (Bartett et al., 2001; FAO Meeting, 2008).
