Tomato (Solanum lycopersicum L.) is among the most important vegetable crops worldwide. Early blight disease, caused by Alternaria solani, a destructive foliar disease of tomato and other Solanaceae species. Herein, we investigated in vitro antifungal properties gallic acid two its derivatives (syringic pyrogallic acids) against A. solani during 2019 2020 seasons. The physiological biochemical effects these compounds on infected plants were also using whole plant bioassay. investigation...
Tomato early blight, caused by Alternaria solani, is a destructive foliar fungal disease. Herein, the potential defensive roles of benzoic acid (BA) and two its hydroxylated derivatives, ρ-hydroxybenzoic (HBA), protocatechuic (PCA) against A. solani were investigated. All tested compounds showed strong dose-dependent fungistatic activity significantly reduced disease development. Benzoic acid, enhanced vegetative growth yield traits. Moreover, BA derivatives induce activation enzymatic (POX,...
Squash (Cucurbita pepo L.), one of the most important vegetable crops for human nutrition all over world, is infected by many diseases, particularly powdery mildew caused Podosphaera xanthii (syn. Sphaerotheca fuliginea), which considered serious disease causing yield losses. This research study was conducted to investigate role Bacillus subtilis, chitinosporus, pumilus, megaterium, polymexa, Trichoderma harzianum, and viridi on squash leaves with P. under laboratory greenhouse conditions....
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 Alternaria alternata, causal agent early blight disease. current study investigated potential antifungal activity four cinnamate derivatives including cinnamic acid, ρ-coumaric caffeic ferulic acid against A. alternata. Our in vitro findings showed that all tested compounds exhibited dose-dependent...
The potato (Solanum tuberosum L.) is one of the most widely consumed vegetable crops worldwide. During storage, tubers are vulnerable to various phytopathogenic fungi. Dry rot, caused by Fusarium incarnatum, a common and serious disease that affects tubers, leading partial or complete decay during storage. current study assessed effectiveness three ethanolic extracts including cinnamon bark (CIB), clove buds (CLB), avocado seeds (AVS) in controlling dry rot under both normal cold storage...
Bacterial wilt, caused by Ralstonia solanacearum, poses a significant threat to Solanaceae crops, including potatoes. Traditionally, chemical bactericides have been the primary method of disease management. However, excessive and repeated use these chemicals has led emergence resistant R. solanacearum strains raised environmental safety concerns. Therefore, current study aimed explore bacteriophages as sustainable eco-friendly alternative control. Specifically, we evaluated efficacy...
Cucumber as an important vegetable crop faces a variety of abiotic and biotic stresses, especially the recently appeared fungicide-resistant strains Pseudoperonospora cubensis, causal agent downy mildew disease. Herein, present study aimed to evaluate effect Trichoderma asperellum strain T34 biological commercial product potassium phosphite (KPHI) against P. cubensis investigate ability these compounds activate plant defense system suppress infection. In two separate experiments, foliar...
Sweet pepper (Capsicum annuum L.) is one of the most widely produced vegetable plants in world. Fusarium wilt dangerous soil-borne fungal diseases worldwide. Herein, we investigated antifungal activities and potential application two chalcone derivatives against phytopathogenic fungus, equiseti, causal agent disease vitro vivo. The tested compounds included 3-(4-dimethyl amino-phenyl)-1-{6-[3-(4 dimethyl amino-phenyl)-a cryloyl]-pyridin-2-yl}-propanone (DMAPAPP) its metal complex with...
Sweet pepper (Capsicum annuum L.), also known as bell pepper, is one of the most widely grown vegetable crops worldwide. It attacked by numerous phytopathogenic fungi, such Fusarium equiseti, causal agent wilt disease. In current study, we proposed two benzimidazole derivatives, including 2-(2-hydroxyphenyl)-1-H (HPBI) and its aluminum complex (Al-HPBI complex), potential control alternatives to F. equiseti. Our findings showed that both compounds demonstrated dose-dependent antifungal...
Blue mold disease, caused by Penicillium italicum (P. italicum), presents a significant challenge to orange fruits (Citrus sinensis L.) and other citrus crops globally. Biological control, particularly Trichoderma species, offers promising alternative synthetic fungicides. Therefore, this study aimed isolate, identify, evaluate the antagonistic activities of two isolates against P. italicum. These were molecularly identified assigned accession numbers PP002254 PP002272, respectively. Both...
A novel azo dye ligand, formed by the coupling of 5‐aminosalycalic acid (mesalamine drug) with 2‐amino pyrimidine (H 2 L) and its Co 2+ , Ni Cu complexes, was synthesized. The structures ligand complexes have been described elemental analysis, inductively coupled plasma (ICP), thermogravimetric analysis (TGA), magnetic moment measurements, molar conductance, ultraviolet–visible (UV–Vis), X‐ray powder diffraction, infrared (IR), 1 H‐nuclear resonance (NMR), 13 C NMR, electron impact (EI) mass...
White rot, caused by Stromatinia cepivora (Anamorph: Sclerotium cepivorum Berk), is a serious soil-borne disease of the onion that restricts its cultivation and production worldwide. Herein, we isolated characterized plant growth-promoting rhizobacterium Stenotrophomonas maltophilia from healthy roots an endophytic bacterium Serratia liquefaciens bean leaves. Both isolates showed strong fungistatic activity against S. using dual culture filtrate methods. This effect might be due to presence...
