Nemaslug and resowing advice please!

[Flapjack]

Hello! Please could an experienced gardener offer some advice?

We have suffered many losses due to slugs this year, especially emerging seedlings. We are organic so my husband applied a biological control called nemaslug yesterday. We used this last year and it was very effective - I am cross that I didn't bother earlier this season.

My question is - when can I start sowing again? Having lost 5 sowings of radishes already, I don't want to waste even more seeds. The nemaslug says it takes a week to work. Does anyone have experience with this? Is that accurate? I could just wait a couple of weeks but it keeps getting later and later. I know I can sow the radishes quite late but a lot of my seed packets are reaching the end of their sowing times!

Isn't nemaslug only supposed to last for 6 weeks, I'd give it about a week before planting out. Could you not start you seedlings off in some old guttering first then slide the contents into your prepared nematode home in about a weeks time.
