Litsea cubeba is an important woody oil plant. The essential oils (EOs) can be extracted from its flowers, leaves and peels and, by volume, it the most exported natural EOs China. Thus, L. has economic medicinal value. Although there demand for rapid expansion of production, been a sharp reduction in resources. Therefore, determining potentially suitable area expanding cultivation will help meet growing volatile oil. Based on 453 distribution records China 16 major environmental factors, we...
Rice sheath blight, caused by the fungus Rhizoctonia solani, poses a significant threat to rice cultivation globally. This study aimed investigate potential mechanisms of action camphor derivatives against R. solani. Compound 4o exhibited superior fungicidal activities in vitro (EC50 = 6.16 mg/L), and vivo curative effects (77.5%) at 500 mg/L were significantly (P < 0.01) higher than positive control validamycin·bacillus (66.1%). Additionally, compound low cytotoxicity acute oral toxicity...
Abstract One of the key goals ecology is to understand how communities are assembled. The species co‐existence theory suggests that community β‐diversity influenced by pool and assembly processes, such as environmental filtering, dispersal events, ecological drift biotic interactions. However, it remains unclear whether there similar patterns among different soil microbial groups all these mechanisms play significant roles in mediating patterns. By conducting a broad survey across Chinese...
Maize (Zea mays L.) is a major economic crop worldwide. can be infected by Alternaria species causing leaf blight that result in significant losses. In this study, 168 isolates recovered from symptomatic maize leaves were identified based on morphological characteristics, pathogenicity, and multilocus sequence analyses of the genes glyceraldehyde-3-phosphate dehydrogenase (GAPDH), internal transcribed spacer ribosomal DNA (rDNA ITS), RNA polymerase II second largest subunit (RPB2), histone3...

Antifungal activity results showed that most synthetic compounds exhibited broad-spectrum activities six fungi in vitro. Notably, b c15 remarkable Colletotrichum gloeosprioides, Rhizoctonia solani, Phytophthora nicotianae var. nicotianae, Diplodia pinea, acutatum, Fusarium oxysporum f. sp. niveum, which...
β-pinene is a monoterpene isolated from turpentine oil and numerous other plants’ essential oils, which has broad spectrum of biological activities. In the current work, six novel quaternary ammonium (β-PQA) salts were synthesized evaluated in vitro for their antifungal, antibacterial anticancer The assay results revealed that compounds 4a 4b presented remarkable antimicrobial activity against tested fungi bacteria. particular, compound showed excellent activities F. oxysporum f.sp. niveum,...
Abstract BACKGROUND Rice sheath blight caused by Rhizoctonia solani is a severe threat to the yield and quality of rice. Due unscientific abuse common fungicides causing resistance environmental issues, development new necessary. In this study, we used citral as lead compound, designed synthesized series novel amide derivatives, evaluated their antifungal activity mode action against R. . RESULT Bioassay results indicated that activities most derivatives were significantly improved compared...
Strobilurin fungicides are some of the most potent and successful agrochemicals. However, continued use traditional strobilurins has led to emergence fungicide-resistant biotypes. Thus, a supply new strobilurin is highly valuable. In this study, series novel methoxyacrylate analogs containing cyano-substituted hydrazine moiety as side chain was synthesized evaluated for their anti-plant pathogenic activities.Compounds 2-04, 2-05, 2-07 2-14 exhibited relatively broad range fungicidal...
Pests threaten worldwide food security by decreasing crop yields and damaging their quality. Natural product-based molecular design structural optimization have been one of the most effective ways to innovate pesticides for integrated insect management. To continue our previous studies on discovery insecticidal lead, a series evodiamine derivatives were designed, synthesized, evaluated activities. The bioassay results demonstrated that compounds Ian Iao exhibited 90 80% activities against...
Abstract Species composition and structure of strongylid (Nematoda: Strongylidae) community were examined in 15 plains zebras (Equus burchelli) 8 Grevy’s zebra grevyi) kept the “Askania-Nova” Biosphere Reserve (Ukraine). Strongylids collected from vivo following deworming with “Univerm” (0.2 % aversectin C, Russia). Twenty-two species (3 subfamily Strongylinae 19 — Cyathostominae) found. In zebras, 21 found; 3 to 14 per host. 18 recorded; 4 Cyathostominae dominated communities both species;...
