“…Such results provide a practical way for overcoming disease stress to sorghum plants by cultivating the resistant cultivars in heavy infested areas of the pathogen. Such results are in accordance with those reported by Claflin (1991), Jardine and Leslie (1992), Karunakar et al, (1993) and Asran (1998). They concluded that differences in sorghum cultivars in their reaction to disease may be due to physiological and / or histological aspects.…”

Grain sorghum [Sorghum bicolor L. (Moench)] is subjected to infection by certain diseases causing great and substantial damage to the crop. Fusarium stalk rot of sorghum caused by F. moniliforme (J. Sheld) represents the common stalk rot in Egypt and many areas of the world. The tested sorghum cultivars reacted differently to F. moniliforme in the two tested seasons. Giza15 sorghum cv. exhibited the highest percentage of infection and disease index followed by Shandaweel 6. Dourado sorghum cv. exhibited the lowest percentage of infection and disease index in both growing seasons. In vitro, the microelements (copper, zinc, manganese and their mixture) at 2g L-1 significantly reduced the linear growth of F. moniliforme. Copper and the mixture treatment exhibited the highest toxic effect on the tested pathogen, followed by zinc. Manganese exhibited the lowest toxic effect. Seed treatments with different microelements significantly increased peroxidase activity in sorghum leaves as compared with untreated ones. The highest peroxidase activity was obtained in both sorghum cultivars with the mixture treatment and copper then, zinc treatment. Treatment of sorghum seeds with manganese exhibited the lowest peroxidase activity in both Giza15 and Dourado sorghum cultivars. Chlorophyll a and b concentrations in the leaves of copper-and zinc-treated plants were significantly higher than those of manganese compared with untreated plants (control). In mixture treatments, the interaction between sorghum cultivars and microelements had significant effect on chlorophyll content. Based on the present data, it is recommended to use a mixture of microelements on grain sorghum to control or at least alleviate the infection by F. moniliforme.

“…After three weeks of sowing, sorghum plants were thinned to two plants per hill. Fourteen days post-flowering, artificial inoculation was performed, approximately 10 cm above the ground, by piercing a sterile needle followed by inserting a toothpick containing A. strictum mycelia into plant stalk between the leaf sheath and the stalk [ 43 ]. Four weeks later, the stalks were longitudinally sectioned, and the disease ranting was determined using the scale ( Table 1 ).…”

Humic Acid-Coated Fe3O4 Nanoparticles Confer Resistance to Acremonium Wilt Disease and Improve Physiological and Morphological Attributes of Grain Sorghum

et al. 2022

Acremonium wilt disease affects grain quality and reduces sorghum yield around the globe. The present study aimed to assess the efficacy of humic acid (HA)-coated Fe3O4 (Fe3O4/HA) nanoparticles (NPs) in controlling acremonium wilt disease and improving sorghum growth and yields. During the season 2019, twenty-one sorghum genotypes were screened to assess their response to Acremonium striticum via artificial infection under field conditions and each genotype was assigned to one of six groups, ranging from highly susceptible to highly resistant. Subsequently, over the two successive seasons 2020 and 2021, three different concentrations of 10, 40 and 80 mg L−1 of Fe3O4/HA NPs were tested against A. striticum. The concentrations of 40 and 80 mg L−1 were found to be highly effective in controlling acremonium wilt disease on different sorghum genotypes: LG1 (highly susceptible), Giza-3 (susceptible), and Local 119 (resistant) genotypes. After harvest, the physiological (growth and yield) and biochemical (peroxidase, catalase, and gibberellic acid) attributes of sorghum plants were determined, and the results demonstrated that concentrations of 40 and 80 mg L−1 increased peroxidase and catalase activities in healthy (uninoculated) sorghum genotypes compared to inoculated sorghum genotypes. Additionally, the toxicity of Fe3O4/HA NPs on male albino rats was investigated via hematological (CBC), chemical (ALT and AST) and histopathological analyses. The concentration 80 mg L−1 of Fe3O4/HA NPs caused a marked increase in ALT and creatinine level after 51 days of feeding. Severe pathological alterations were also observed in liver and kidney tissues of rats administered with grain sorghums treated with 80 mg L−1. In comparison with the untreated control plants, a concentration of 40 mg L−1 significantly increased the growth, yield and gibberellic acid levels (p ≤ 0.05) and was found to be safe in male albino rats. Conclusively, a concentration of 40 mg L−1 of Fe3O4/HA NPs showed promising results in curtailing A. striticum infections in sorghum, indicating its great potential to substitute harmful fertilizers and fungicides as a smart agriculture strategy.
