The entomopathogenic fungus Beauveria bassiana was established in coffee seedlings after fungal spore suspensions were applied as foliar sprays, stem injections, or soil drenches. Direct injection yielded the highest post-inoculation recovery of endophytic B. bassiana. Establishment, based on percent recovery of B. bassiana, decreased as time post-inoculation increased in all treatments. Several other endophytes were isolated from the seedlings and could have negatively influenced establishment of B. bassiana. The recovery of B. bassiana from sites distant from the point of inoculation indicates that the fungus has the potential to move throughout the plant.
在将真菌孢子悬浮液作为叶面喷雾、茎部注射或土壤浇灌施用于咖啡幼苗后，昆虫病原真菌球孢白僵菌在幼苗中定殖。直接注射在接种后内生球孢白僵菌的回收率最高。在所有处理中，基于球孢白僵菌回收率的定殖率随着接种后时间的增加而降低。从幼苗中分离出了其他几种内生菌，它们可能对球孢白僵菌的定殖产生了负面影响。从远离接种点的部位回收球孢白僵菌表明该真菌有在整株植物中移动的潜力。
