What would make it a big no no? I can't think of anything you might apply to a plant that shouldn't be applied when flowering or fruiting.

@digdirt2: instructions don't say not to.... all it says is minimum 3 days inbetween and a maximum of 10 treatments. But I just wana make sure

@daninthedirt : the reason I asked the question is cause I remembered having read it is not recommended to spray lime sulfur on blossoming trees, in my case apple trees.

thanks

That is a good question. Will the chemicals in the fungicide interfere pith pollination ? I don't know the answer myself. When I am spraying , I try as much as possible not to spray the blossoms.

Copper Sulphate can be caustic to leaves and blossoms but many of the newer spray materials have been "Tamed" so there is usually no problem if you follow the label. I'm not familiar with the pictured product. DuPont has a series of copper products for different purposes.

Stef,

You read the instructions, then you remembered something else?

now you want assurance from the Internet? How old are you?

Not very nice Jim. Better to ask first than to do it and then ask what happened after.

Wow Jim, what a horrible post :(

IMO,
fungicide is a VERY important part of growing tomatoes.

I use the Copper Fungicide from Bonide. ("Suitable for organic gardening.")

I start
spraying - from day 1 - when I transplant the seedling, till September / October. Every week,
on both sides of the leaves. Some spray every 10 days, or every 2 weeks. Some even don't spray at all - which I think is not a brilliant idea.

So I spray the plants on ALL their stages, and I never had ANY kind of problems with my tomatoes.

I always spray in the morning - NEVER in the evening. And - obviously - never before a rain.

I use goggles and gloves. I wear long sleeve shirt, and pants. Not SHORT pants.

For spraying, I use this
awesome One-Hand Pressure Sprayer, by Solo who has –
among other goodies - a “Multi-directional nozzle
allows spraying from all positions.”

Spraying fungicide - done diligently - can be a VERY time consuming operation, if you have many plants. It can take a few hours.

A rule
that I follow, is that if you can see through the “jungle” you don’t need to
prune. But if you CAN’T see, fungicide is not only very difficult, but has no
efficiency.

If the instructions say it's approved for edibles, go ahead. I went to a tomato class at a reputable local nursery and everyone there swore by Liquicop - a copper fungicide.

thank you for your help everyone. Greatly appreciated. I will give it a try

Regards
