The present work involved the synthesis and characterisation of mesoporous alumina sphere (MAS) nanoparticles to evaluate their biological activity against tomato root rot caused by Fusarium oxysporium, as compared with the recommended fungicide, tolclofos-methyl, under laboratory and greenhouse conditions. The effects of MAS nanoparticles on the growth of tomato plants were also evaluated and compared with those of tolclofos-methyl.
The physical characteristics and structural features of MAS nanoparticles, such as their large surface-area-to-volume ratio, active surface sites and open channel pores, caused high antifungal efficacy against F. oxysporium. MAS nanoparticles presented an antifungal potential similar to that of tolclofos-methyl and much greater than that of the control under both laboratory and greenhouse conditions. The highest growth parameters were recorded in tomato plants treated with MAS nanoparticles, followed by those treated with tolclofos-methyl.
Our study demonstrated the possible use of cylindrically cubic MAS nanoparticles as an effective alternative for the control of Fusarium root rot in tomato. © 2016 Society of Chemical Industry.
本研究涉及介孔氧化铝球（MAS）纳米颗粒的合成与表征，旨在评估其在实验室和温室条件下对尖孢镰刀菌引起的番茄根腐病的生物活性，并与推荐的杀菌剂甲基立枯磷进行比较。同时还评估了MAS纳米颗粒对番茄植株生长的影响，并与甲基立枯磷进行比较。
MAS纳米颗粒的物理特性和结构特征，如大的表面积与体积比、活性表面位点和开放通道孔，使其对尖孢镰刀菌具有较高的抗真菌功效。在实验室和温室条件下，MAS纳米颗粒均表现出与甲基立枯磷相似的抗真菌潜力，且远高于对照。用MAS纳米颗粒处理的番茄植株生长参数最高，其次是用甲基立枯磷处理的植株。
我们的研究表明，圆柱形立方MAS纳米颗粒有可能作为控制番茄镰刀菌根腐病的有效替代品。©2016化学工业协会。
