“…Among PPs, fludioxonil, used alone or in mixture with other fungicides, has been largely used for cereals and soybean seed treatment, showing a high efficacy against Fusarium species [53,54,55,56]. We showed that all Fusarium and Aspergillus strains tested were slightly inhibited by this compound, and fungal growth inhibition was not correlate to the increasing fludioxonil concentrations.…”

Aspergillus flavus, the main aflatoxin B1 producing fungal species, Fusarium graminearum, a deoxynivalenol producer, and the fumonisin-producing species F. proliferatum and F. verticillioides are the main toxigenic fungi (TF) that colonize maize. Several strategies are available to control TF and related mycotoxins, such as chemical control. However, there is poor knowledge on the efficacy of fungicides on maize plants since few molecules are registered. The sensitivity of F. graminearum, F. proliferatum, F. verticillioides, and A. flavus to eleven fungicides, selected based on their different modes of action, was evaluated in both in vitro assays and, after selection, in the field. In vitro, demethylation inhibitors (DMI) showed excellent performances, followed by thiophanate-methyl and folpet. Among the succinate dehydrogenase inhibitors (SDHI), isopyrazam showed a higher effectiveness against Fusarium species than boscalid, which was ineffective against Fusarium, like the phenyl-pyrrole fludioxonil. Furthermore, both SDHIs and fludioxonil were more active against A. flavus than Fusarium species. In field trials, prothioconazole and thiophanate-methyl were confirmed to be effective to reduce F. graminearum (52% and 48%) and F. proliferatum contamination (44% and 27%). On the other hand, prothioconazole and boscalid could reduce A. flavus contamination at values of 75% and 56%, respectively.

“…The integration of multiple disease management approaches including use of cultivars with Rps genes in combination with fungicide seed treatment is strongly recommended when there is a high risk for disease development (Dorrance, 2018). Fungicide seed treatments have been shown to provide protection during the vulnerable time period after planting, especially under conditions likely to result in disease development (Dorrance & McClure, 2001; Ellis et al., 2008; Munkvold, 2009; Munkvold et al., 2014; Scott et al., 2020; Urrea et al., 2013). Fungicide‐only seed treatments have been found to increase plant stand and final yield performance in locations with moderate to high P. sojae pressure (Bradley, 2008; Dorrance, 2018; Dorrance et al., 2009).…”

Phytophthora root and stem rot is a devastating disease of soybean [Glycine max (L.) [Merr.] that occurs annually in North America.

The first objective was to determine the efficacy of oxathiapiprolin as a soybean seed treatment using laboratory inoculum layer assays with different races of Phytophthora sojae. The second objective was to evaluate oxathiapiprolin seed treatments in wide area agronomic field testing using unmanned aerial vehicle (UAV) image-to-data analysis to quantify emergence, vigor, and greenness traits. The final objective was to examine the yield potential of seed treatments with oxathiapiprolin. Using inoculum layer efficacy testing in a growth chamber with P. sojae races 4, 7, or 31, seed treated with oxathiapiprolin had significantly higher visual root growth scores compared to non-treated seed. Across 115 field locations from 2018-2020, UAV remote sensing image analysis at the V2 growth stage indicated oxathiapiprolin in combination with other fungicides had significantly better emergence, more vigor, and more intense greenness compared to non-treated controls. Entries treated with oxathiapiprolin in combination with other fungicides had an average +161 kg/ha yield difference compared to non-treated entries from 2018 to 2020. Oxathiapiprolin as a seed treatment is an effective management tool for soybean producers, providing efficacy against P. sojae, and improving emergence, vigor, greenness, and final yield.

“…In the last decades, seed coated with proper chemical compounds have been widely used to reduce the impact of fungal diseases of the maize plants during the first growing stages. In particular, sowing coated maize seeds protects seedling plants in their first growth stage . Moreover, this agronomic practice can contribute to reduce further chemical treatments, thus reducing also the impact on environment and farmer health.…”

The aim of the research work here reported is to illustrate how to incorporate prothioconazole, a molecule with fungicide action, in plasma‐deposited polymeric coating, encapsulating maize seeds. With this approach, high fungicide effect with a small quantity of chemicals and less pollution of soil and water should be achieved. The fungicide composite coating is composed of three layers: a hydrophilic plasma deposited polymeric layer to increase the wettability of the seed surface; a layer of sprayed prothioconazole aqueous solution; and a hydrophobic plasma deposited barrier layer to limit leaching and mimic the natural seed wettability. The application of the composite coating is found not to interfere with the germination of the seeds, while the percentage of maize crowns infected by Fusarium graminearum was successfully reduced from 94% in the control to none in the coated seeds.
