Evaluation of Five Cultivars against Leaf Blight Disease Caused by at Rooting and Seedling Growth Stages.

During the winter of 2018, leaf blight on florist's daisy ( L.) was noticed in Egypt. The disease, which was identified as caused by , was widely spread and led to serious damage for the exportation sector of this crop.

Hydroxylated Cinnamates Enhance Tomato Resilience to , the Causal Agent of Early Blight Disease, and Stimulate Growth and Yield Traits.

The important vegetable crop, tomato, is challenged with numerous abiotic and biotic stressors, particularly the newly emerged fungicide-resistant strains of phytopathogenic fungi such as , the causal agent of early blight disease. The current study investigated the potential antifungal activity of four cinnamate derivatives including cinnamic acid, -coumaric acid, caffeic acid, and ferulic acid against . Our in vitro findings showed that all tested compounds exhibited dose-dependent fungistatic action against when their concentrations were increased from 0.

Nanofungicides with Selenium and Silicon Can Boost the Growth and Yield of Common Bean ( L.) and Control Alternaria Leaf Spot Disease.

There is an urgent need to reduce the intensive use of chemical fungicides due to their potential damage to human health and the environment. The current study investigated whether nano-selenium (nano-Se) and nano-silica (nano-SiO) could be used against the leaf spot disease caused by in a common bean ( L.).

Paclobutrazol Improves the Quality of Tomato Seedlings to Be Resistant to Blight Disease: Biochemical and Histological Perspectives.

The production and quality of tomato seedlings needs many growth factors and production requirements besides controlling the phytopathogens. Paclobutrazol (PBZ) has benefit applications in improving crop productivity under biotic stress (, the causal agent of early blight disease in tomatoes). In the current study, the foliar application of PBZ, at rates of 25, 50, and 100 mg L, was evaluated against early blight disease in tomatoes under greenhouse conditions.

Benzoic Acid and Its Hydroxylated Derivatives Suppress Early Blight of Tomato () via the Induction of Salicylic Acid Biosynthesis and Enzymatic and Nonenzymatic Antioxidant Defense Machinery.

Tomato early blight, caused by , is a destructive foliar fungal disease. Herein, the potential defensive roles of benzoic acid (BA) and two of its hydroxylated derivatives, -hydroxybenzoic acid (HBA), and protocatechuic acid (PCA) against were investigated. All tested compounds showed strong dose-dependent fungistatic activity against and significantly reduced the disease development.

Nano-selenium, silicon and HO boost growth and productivity of cucumber under combined salinity and heat stress.

The production of cucumber under combined salinity and heat stress is a crucial challenge facing many countries particularly in arid environments. This challenge could be controlled through exogenous foliar application of some bio-stimulants or anti-stressors. This study was carried out to investigate the management and improving cucumber production under combined salinity and heat stress.

Development of Interspecific Hybrids between a Cultivated Eggplant Resistant to Bacterial Wilt () and Eggplant Wild Relatives for the Development of Rootstocks.

Bacterial wilt caused by is one of the most economically and destructive eggplant diseases in many tropical and subtropical areas of the world. The objectives of this study were to develop interspecific hybrids, as potential rootstocks, between the eggplant () bacterial wilt resistant line EG203 and four wild accessions ( UPV1, UPV2, UPV3, and UPV4), and to evaluate interspecific hybrids along with parents for resistance to bacterial wilt strains Pss97 and Pss2016. EG203 was crossed successfully with wild accessions UPV2 and UPV3 and produced viable seeds that germinated when wild accessions were used as a maternal parent in the crosses.
