摘要

在PDA中以不同浓度（1000、500、250、100、50mg/ml）对龙葵和角藻的丙酮和甲醇叶提取物部分进行了抗甜瓜果实腐烂病病原体相球藻的试验。所有提取物浓度均表现出显著的活性（P<0.05），且具有剂量和物种依赖性。丙酮提取物的活性优于甲醇提取物，在500mg/ml浓度下对黑曲霉和1000mg/ml浓度下，丙酮提取物对真菌生长具有100%的抑制作用。提取物的植物化学测试显示，存在不同程度的次生代谢产物，其中黄酮类化合物和单宁浓度较高，这可能是观察到的真菌毒性活性的原因。这项研究的结果揭示了茄科杂草作为抗真菌剂的潜力。因此，我们建议将这些提取物作为农田土壤浸液，进行田间配方和试验，以对抗土壤传播的病原体

FUNGICIDAL ACTIVITY OF SOLANUM NIGRUM AND PHYSALIS ANGULATA EXTRACTS AGAINST MACROPHOMINA PHASEOLINA, A FRUIT ROT PATHOGEN OF MELON (CITRULLUS COLOCYNTHIS (L.) SCHRAD

Acetone and methanol leaf extracts fractions of Solanum nigrum and Physalis angulata at various concentrations (1000, 500, 250, 100, 50 mg/ml) in PDA were tested against Macrophomina phaseolina, a pathogen of fruit rot disease of melon. All the extract concentrations showed significant (P<0.05) activity with dose and species-dependent effect against the phytopathogen. Acetone extracts had superior activity over methanol extracts with 100% inhibition of fungal growth at 500mg/ml for S. nigrum and 1000mg/ml for P. angulata. Phytochemical tests of the extracts revealed the presence of secondary metabolites in varying degrees with high concentrations of flavonoids and tannins which may be responsible for observed fungitoxic activity. The results of this study have uncovered the potentials of the Solanaceous weeds as antifungal agents. We therefore suggest field formulations and trials of these extracts as soil drench in agricultural farms against soil-borne pathogens
