用琼脂扩散法测定了208种植物（如林木、草本、灌木、果树、香料、蔬菜、食用豆类、饲料、油料、纤维作物、谷类和蔬菜）的扩散液对野油菜黄单胞菌致病变种（Xanthomonascampestrispv.）柑橘。大多数林木、草本和灌木的扩散物对XC-100菌株有抑制作用。从余甘子、阿拉伯金合欢、无患子和诃子的各个部位的扩散物，在50 g l（-1）浓度下显示出4.83-6.00 mm的抑制区，似乎是最有效的。即使在1.25 g l（-1）的浓度下，这些扩散液也显示出抑制作用。浓度为50、20和10 g l（-1）的这些扩散物在减少离体叶片和果实上的病害数量方面显著（P < 0.01）更有效，因此表现出保护和治疗作用。因此，从高等植物的扩散，似乎是潜在的抗菌剂，可用于管理柑橘溃疡病。
Two hundred and eight diffusates from various plants such as forest trees, herbs, shrubs, fruit trees, spices, vegetables, food legumes, fodder, oil seed, fibre crops, cereals and ornamentals were evaluated through agar diffusion assay to determine their inhibitory action, if any, against Xanthomonas campestris pv. citri. Diffusates from the majority of forest trees, herbs and shrubs showed an inhibitory effect against strain XC-100 of the bacterium. Diffusates from various parts of Phyllanthus emblica, Acacia nilotica, Sapindus mukorossi and Terminalia chebula, which exhibited an inhibition zone measuring 4.83-6.00 mm at 50 g l(-1) concentration, appeared to be the most effective. These diffusates showed an inhibitory effect even at a concentration of 1.25 g l(-1). These diffusates at concentrations of 50, 20 and 10 g l(-1) were significantly (P < 0.01) more effective in reducing the number of lesions on detached leaves and fruits, thus exhibiting protective as well as curative actions. Diffusates from higher plants, therefore, appear to be potential antimicrobial agents which could be used for the management of citrus canker disease.
