Using Copper Sulfate on Tomatoes

This video is About Organic Pesticides

[@truettyarbrough1422]

Suggest all of you doubters look this definition up at Cornell University, “It is also used as an algaecide, an herbicide in irrigation and municipal water treatment systems, and as a molluscicide, a material used to repel and kill slugs and snails. Copper sulfate is a naturally-occurring inorganic salt and copper is an essential trace element in plant and animal nutrition (5, 6, 7, 13, 16).”

I want to thank you for sharing your wisdom with us!!! You made a great educational video, thank you. We have always had this problem and no other solution has worked. Thanks again.

[@truettyarbrough1422]

Thanks for your question. I don’t see why not. I would give it a try on one plant and check it for 2-3 days before moving to all plants if the first one you used it on looks good.

[@truettyarbrough1422]

If my problems are not too serious I mix 2 tablespoons per gallon, if the problem still exists 5-10 days later I go with 4 tablespoons per gallon.

[@truettyarbrough1422]

Thanks for your comment. I love gardening and of course I have the same problems everyone else does. I just love sharing things I find that make gardening easier and more fun.

[@genekerr8064]

Awesome. I have used copper sulfate to keep the watering trough clear for our livestock.

How to make past or liquid

[@dustintravis8791]

Straight talker, I like it. I use bungee cords as well, they work great.

[@spiderstone]

Hey buddy, how much do I mix with a gallon of water in my sprayer....?...is it safe?

[@johnmcwilliams7918]

nice looking tomatoes,haven't used copper sulfate in the garden always. in ponds and lakes for moss problems but looks like it controls blight, thanks 👍

[@MrThemortgage]

I found 2 TBSP per gallon of water too strong and it burned a few leaves on my plants. It did stop the Blight. I will try 1 TBSP per gallon next time I spray and see how that goes. Also, I will start spraying my plants with Baking Soda, Corn oil and dish soap when they start showing blossoms to prevent White Powdery Mold that I often get. Definitely test on one plant, spray and wait 2-3 days to be sure it's not too strong a mixture.

Nice tomatoes. I grow the tomato plants I sell at the flea market, Crimpson Sprinters "early", Illinois Beauties, and Peacevine Cherry "de-hybridized Sweet-100s". One of my Illinois beauties got about 14 feet long, it grew over and out of my 7-foot cage and touched the ground, the Peacevine got about 19 feet long 2 years ago so I plant those late and in the shade to keep is small. One of my plants got early blight and was wondering if copper sulfate would help when I found this video. I guess it does.

[@troytaylor1913]

I'll probably mix is half as strong. like other things that are good for tomatoes, it will probably will help other plants in my garden like powdery mildew on roses and cucumbers, and peas.

Hi, you don't seem worried about skin contact with this. The reason I ask is because I used it for the 1st time this year and the very next day I was SO sick. Felt very flu like, which has come and gone all through the week after. My concern is when I sprayed taller tree branches, overspray had hit my face, I washed immediately, but I don't know if I incurred some copper poisoning. We did a concentrate of just under 2 oz with gallon of water. The tree is looking SO much better, will still need to re-apply in a few spots though. Ever had a problem?

[@patwalker9890]

I bet it was coincidence that you got sick. Either that or you have rare sensitivity to copper.

[@stardust9072]

same with me. but i had mask normal on. the mist only touch my skin and eyes. felt ill the next day and it last many days

[@simonjack8122]

Is that a small amount of copper sulphate crystals mixed up in water? How much should i mix in a sprayer like yours without harming my plants?

[@Poetaliahmadali]

Sir . Are u sured copper sulphate control the blight and fungus problems in tomatoes. If its control thats amazing

[@roygee1283]

use lime in your mix as well

[@roygee1283]

1tbl spoon of each in 10l water.

[@adexbiola1660]

​@@roygee1283how effective is this please

[@joshgordon2484]

Can you also just sprinkle copper sulfate dust on the tomatoes or is that too strong, please.

[@truettyarbrough1422]

Josh, I’m really not sure. I’ve never tried that.

[@appletechpro3964]

Please let me know, how to make copper sulfate solution? How many grams or ozone for gallon ?

[@truettyarbrough1422]

I use Southern Ag liquid copper sulfate concentration. One bottle makes 48 gallons. Thanks for your question. The mixing directions are on the bottle. I get it at Lowes

[@Poetaliahmadali]

Sir . kindly tell me about why u r using copper sulphate? Answer me in detail i wait u dear

[@lunabeta3516]

I HAVE NEVER EVER SEEN TOMATO PLANTS THAT BIG

[@heaanlasai866]

Thanks for this upload! I'm having problems with germination: My chili seeds won't germinate without heat. With heat they germinate, but the seedlings get mould before being ready to plant. Can I add a little copper sulfate to the water which I use in paper towel seed germination to combat mould? I clean the seeds with hydrogen peroxide first to eliminate spores, but one way or another some mold spores get in via the air.

[@tonymetro4707]

It's your growing medium and pots then.

[@karunald]

Can anyone recommend a dose for BONIDE copper concentrate? They give a range of 1-4 TBL/gallon. IDK what dose to go with with early blight and some bacterial issues.

[@Dargyful]

Is that stuff safe ?

[@MJS12409]

How often do you have to spray the tomatoes once the blight/fungus is present? thank you,

[@truettyarbrough1422]

Thank you for your question. I try to spray every 2 weeks if a fungus or blight is present. Sometimes in Florida Summers we get so much rain that I have to hold off a day or two but I get in done ASAP. Thanks again for your question, hope this helps.

What is the ratio of copper sulphate and water and Interval between two spray times.

[@serenemountain6769]

if you are being methodical, Applying 2 g copper sulphate / m3 of water, it is strong stuff ...

[@Finom1]

We need more videos!!! Are you still alive???

[@truettyarbrough1422]

Yes, sorry I’ve been busy with other things on the farm. Thanks so much for your comment. I’ll try to get something done by the end of May. Thanks again.

[@stevesyoutubechannel1604]

Hi, I've just put some of that on my tomatoes but I was wondering if it has a withholding period or do you just wash the fruit when it's ready to go? There are some pretty serious warnings on my bottle but nothing about withholding periods

[@truettyarbrough1422]

Hey Steve, thanks for your question. I’m not a chemist so the only thing I can say is, follow the label warning. I always wait a few days to consume fruit after spraying it no matter what the label says.

[@MegaMackproductions]

Can I use this on my squash?

[@truettyarbrough1422]

M W. I don’t see why not. I’ve always stuck to label instructions, otherwise I turn to Google.

[@dennisryken6004]

We use copper sulfate to stain concrete blue for floors......it penetrates the concrete....I would never use it on produce.... He should be using a hazmat suit

[@amadeusjean4019]

Where can I get copper sulfate

[@serenemountain6769]

that answer depends on where you live !

[@sangarp2001]

Is copper sulfate poisonous?

[@jomansur]

Yes, extremely

[@serenemountain6769]

that's why you you must use in very small quantities, for it to never harm plant life ! 2 g copper sulphate / m3 of water ... never overdose. its enough to prevent fungus and other harmful bacteria in the water... it also serves has a pesticide for slugs and snails ...
