onyeka Posted January 15, 2017 Hi fellow saber's, I'm searching for a antifungal for seedlings. I used to use cheshunt compound to stop dampening off on my seedlings, but that has been taken off sale here in UK now. Which sucks! What do you guys here use to stop dampening off? Much respect Onyeka Share this post Link to post Share on other sites
Anodyne Posted June 18, 2017 (edited) Dunno if you're still around @onyeka, but if you are I believe you can still buy copper sulphate (and similar copper compounds), which is one of the active ingredients in Cheshunt. The other active (ammonium carbonate) I think was the thing that caused old tins of cheshunt to basically turn to strong sulphuric acid when stored for a long time? So if you're going DIY you may want to leave this out, or just make up enough for your immediate needs. Bordeaux mixture is similar and probably easier to source the ingredients (copper sulphate + lime) for? Instructions here. Cheshunt compound: >Weigh 60 grams of Copper Sulphate & 330 grams of Ammonium Carbonate. >Powder together and mix well. The dry mixture should be stored in an >airtight container for a day or so before use, and can be stored that >way almost indefinitely. Dissolve 25g of this mixture in hot water and >make up to 8 litres with cold water. Bordeaux mixture: "For spraying in small amounts, prepare as above but only >mix 1 gallon of water, 3 1/3 tablespoons of copper sulfate and 10 >tablespoons of hydrated lime. Agitate the mixture thoroughly before >you spray. The homemade Bordeaux mixture needs to be used the day you prepare it. Make sure you rinse the Bordeaux fungicide preparation out of your sprayer with plenty of water, since it is corrosive Make sure you read all the safety stuff if you're not experienced with handling chemicals. Or if you just want something you can buy ready-made, mancozeb works ok - I don't know how it compares with cheshunt though.
