We have been using Provado for some years in all our containers which
has been reasonably successful, but as part of our effort to rely a bit
less on chemicals I was thinking of trying Nemasys. Do you apply the
nematodes once or twice a year and what is/are the optimum month(s) to
apply it from your experience?
You apply it in April and September. The soil temp needs to be about 14C
minimum. At around 26C, it becomes inactive. We use it only in September
as - touch wood - we've been using it for a long time and so have no major
problem. In 8 years I've seen one vine weevil!
However, Ray suggests that if you do have vine weevil now, you use the
control in April (when the soil temp. is right) and again in September until
you've got it under control, then you could well get away with one autumn
treatment.
Many thanks
