Bipolaroxin,是近年来由美国蒙大拿州立大学和康奈尔大学的几位学者,从侵袭常见杂草狗牙根的病原真菌Bipolaris cynodontis中分离出的一种毒素。这种真菌毒素由碳、氢和氧组成,容易被土壤微生物分解。它的发现为生产能专一地毒害某种杂草而且不留残毒的新型除草剂提供了依据。为此,他们正在进一步寻找对其它杂草有毒害作用的真菌毒素。据科学家分析,类似的病原体很可能在这些杂草的原产地被发现,因为这些地区的病原体长期以来专一地侵袭某些寄主。 Bipolaroxin, a toxin isolated from Bipolaris cynodontis, a fungal pathogen that invades the common weed bermudagrass, has been studied by several researchers at Montana State University and Cornell University in recent years. This mycotoxin, composed of carbon, hydrogen and oxygen, is easily broken down by soil microorganisms. Its discovery provides a basis for the production of new herbicides that can specifically poison certain weeds without leaving any residue. For this reason, they are looking further for mycotoxins that are toxic to other weeds. According to scientists, similar pathogens are likely to be found in the origin of these weeds, as pathogens in these areas have long been targeted to certain hosts.
