Hello, Steve, just I need a advice about two producrts, Thricoderma Viride, and Fusarium Oxisporum IF 23 (write in italian), is better to put on my soil now, or in the spring?
Thanks for the help

Wait till spring Sergio.

The type of Trichoderma we use here in the US is: "T. harzianum T22" which is often sold as "Rootshield".

Trichoderma should be applied at planting & again just prior to the time we expect Fusarium to "wake up". Cool wet weather in late spring seems to foster that wake-up call.

Here in CT this year we saw sustained (Fahrenheit) temps of low 60's combine with rain in May so Fusarium came around too early for most growers to react. We're used to seeing wilting in warm weather so we tend to make a second just prior heat which was all backwards this year.

Most bacterial inoculants will shift the soil population for 3 weeks at a time. There is no real harm in applying Trichoderma every 3 weeks...so week 0, week 3 & week 9 as an example.

Perhaps there is a program that can translate some of this page English to Italian? It's a very good read.

I'll follow your advice, in the last year I haven't had in my patch any fusarium or sclerotina ecc.. but I must say that it was a next pach this year will be the second time that I grow pumpkins on it, hopefully don't to have problem this year also, but like you know the problems are ever back the door!
