Tomatoes (Solanum lycopersicum L.) are the most cultivated and important vegetable crop in the world. These plants can wilt during crop growth due to fusarium wilt (fusariosis), a disease that damages tomato vascular systems. The Fusarium isolated and analyzed in this work correspond to Fusarium oxysporum f. sp. radicis-lycopersici. The isolates were molecularly identified, and analysis was done on the in vitro effects of the nanoemulsions (previously obtained from extracts of Chilean medicinal plants of the genera Psoralea and Escallonia) to inhibit mycelial and conidial germination of the isolates. Subsequently, the nanoemulsions were evaluated under greenhouse conditions for preventive control of fusariosis in the root and crown, with high levels of disease control observed using the highest concentrations of these nanoemulsions, at 250 and 500 ppm.

抗真菌纳米制剂生物防治尖孢镰刀菌引起的番茄根腐病。sp. 根茎番茄

番茄（Solanum lycopersicum L.）是世界上栽培最多、最重要的蔬菜作物。由于枯萎病（镰刀菌病），这些植物在作物生长期间可能会枯萎，枯萎病是一种损害番茄血管系统的疾病。该镰刀菌分离并在这项工作中对应于分析尖孢镰刀菌F。sp. 根茎番茄。对分离物进行分子鉴定，并对纳米乳剂（以前从智利补骨脂属和Escallonia属的药用植物提取物获得）的体外作用进行分析。) 以抑制分离株的菌丝体和分生孢子萌发。随后，在温室条件下对纳米乳剂进行了评估，以预防根和冠部的镰刀菌病，使用最高浓度的这些纳米乳剂（250 和 500 ppm）观察到高水平的疾病控制。
