Damn it . . I just sprayed weedkiller on 36 raspberry canes HELP?

I have a patch in the garden it looked like just over grown weeds and grass , so out came the weedkiller only its not all weeds and grass am killing .
There are 20 raspberry canes i stopped as soon as i noticed what they were , but i did spray some is there a chance they won’t die .

When i moved in last year there was bushes and plants ( where the raspberries are now) , i cut all these bushes away and now it seems the raspberries have seen the light and are now growing they are old canes and would have been well established before these bushes were introduced.
Is there anything i can do that will/could help make them survive , or are raspberry canes able to survive even this…..

It was a liquid weedkiller i used and was using a pressurized spray gun, it works by being absorbed through the leaves to destroy whatever its sprayed on . Takes 2 days to show signs of decay , lifting and potting up is not an option at current time .
