Fosetyl induced protection is associated with a hypersensitive response and higher-than-normal levels of phytoalexin accumulation, and resembles the response seen in genetically-resistant plants. A number of other nutrients and growth conditions can affect its direct fungitoxicity, but the balance of evidence indicates that it is not a powerful enough toxicant to explain the activity of Fosetyl in the plant. 0000000456 00000 n "rKCMu yt;m@gP}dl`hyyVrmw allum amaroc agro fongicide systmique {=gTv^D88]`Qz'gfda?k,'Ht`? 0 Plants possess a number of natural defence mechanisms, and infection can only succeed if these defences fail. mL.

On the other hand, there are strong indications that Fosetyl is able to induce a resistant response in the plant following infection. 6]Jgw3A6vkgCmqoQc9Xzl qy/ig81/|+-h|8!t}G?
