You can't pretend the wheat doesn't have head blight, a cow doesn't have blackleg , or that predators don't prey.
There is no chemical cure and all growers can do is let the crop mature and hope the blackleg tubers will rot out.
They are known as ‘Scummers’, a term going back to a dock strike in the fifties, when blackleg labour was brought in to breach the picket lines.
The models revealed telling facts about the spread of anthracnose, blackleg and black spot.
Such other clostridials include black disease, blackleg , braxy, bacterial redwater and tetanus.
Although numerous studies suggest that seedling and adult blackleg resistances are under different genetic controls, many authors have observed a significant correlation between the two.
They were ill organized, and defeated by the import of blackleg labour and drought, which struck in 1905.
This will ensure that any future overcoming of resistance does not result in the complete collapse of the cultivar from blackleg disease as now occurs in some field situations.
Go on strike by all means, but don't be surprised if some unknown blackleg wannabe steals your job.
Since chemical control of the disease poses risks to the producer and the environment, the introduction of genetic resistance to blackleg has become a major objective of canola breeding programs.
