Is Benomyl a contact spray? Is it effective as part of a alternating sray program? Just wondering since its one of the few sprays that can be bought in store here.

Benomyl is not a contact. It is a benzimidazole fungicide in the same family as thiophanate-methyl (Topsin, Cleary's 3336, etc). It's a systemic that only works on active disease. It has no preventive properties at all. It can be useful against fusarium & rhizoctonia if the vascular system is already infected.

I still have some. Another grower recommended making a paste & using to on stem splits instead of Captan. I tried it. Benomyl tends to not flake off as easily as Captan so I've kept using it for this reason.

Benomyl is off the market here in Canada. If you can still find some buy it up. Tell them its off the market first they will probably give you a deal...lol. I use it for patching splits etc. works well.
The better product to use to alternate with your nova is Bravo (sold as Daconil in th US) it is pesticde licience only, but I'm sure the guy that got you the Nova can help you out!
Also Cabrio (Headline) works great as well, but it is a strob so you can only use a couple of times a year.

Benlate, containing Benomyl was banned here some years ago due to a safety issue for the opperators spraying it. Apparently if enough of the product was inhaled by the sprayer opperatives it caused blindness in the unborn children of these opperators. Benlate was the best Fungicide we had and like most products is no longer available.

Dupont stopped making Benomyl (Benlate, Tersan 1991, etc) here in the US after 2 seperate accidental Atrazine (herbicide) contamination incidents. The fools saw that the benomyl market shrinking. So they combined manufacturing of several products in one plant. WOOPS! Once was bad...twice was fatal.

I believe the contamination was with Lorox (Linuron), also made by Dupont! I heard they bought several orange groves in Florida....lol

We sold a pile of Atrazine contaminated Benomyl to an orchid grower in FLA & ended up in court with Dupont trying to decide who was going to buy the guys crop.

There were apparently other contanimants as well.

This Tomato growers case involved atrazine but Dupont anso names Prowl (Pendimethalin) & Prozine....Who knows any more? It gets gray after 17 years.... Dupont rightly tried to name every other person that ever owned, worked in or drove by the plant to spread the liability around.

Plus there was more than 1 incident.
