Our growth chambers for Arabidopsis have powdery mildew. We will clean
one by one but until that happens we have been spraying with a
fungicide the rosette plants and, until now, they don't present
disease signs after that. However I have some questions that I hope
you can help me:
1 - Do you think is more effective to spray the all room at once?
2 - Do the seeds from the plants inside the contaminated rooms (even
without signs of the disease) be likely to generate contaminated seeds?
3 - Can you please advise me about the cleaning, for instance wich
temperature to heat up the room and for how long? We also have thrips.
Thanks a lot,
