lawn care

[badlad]

just been out to cut the lawn and find that there are some large patches of grey crusty stuff that crunches when you walk on it and slimy underneath ,the wife usually takes care of the garden which is why i had not noticed it ,  i have checked on the internet and apparently it is called slymould ,a part of the treatment to get rid of it is to treat with an antifungal so my question is can anyone tell me where i can buy an antifungal liquid or powder in or around bangkok

Pour Vinegar on it.....dont water....job done.

the patch that i treated with vinegar yesterday is already dead but so is the grass so before i treat anymore i think i will wait to see if the grass regrows if it doesn't i am still in need of a supplier for an antifungal agent, amazed how quickly the vinegar worked though ,if the grass picks up again i will try a watered down version next time and spray it on

I didn't answer before as I was a bit surprised at the advice. You can use vinegar as a weed killer, but  I supposed at a diluted dose, maybe..

Anyway, fungi prefer an acid environment so using vinegar doesn't seem right.Do you have acidic soil? Could be one thing to look at. Fungi often develop on badly drained soils, could be another clue.

Treatment: go to a gardening centre or farmers' centre and ask for Captan, I have seen that  here.

thanks for that i will wait and see what happens before i buy captan and yes the soil here is poor at draining but that is another part of the process to get rid of the fungus

Dont worry about it....the grass will return soon enough....Sounds like you used maybe a little too much Vinegar for the area you wanted to treat....another cheap trick is to actually use Urea...put plenty on dont water. Be careful with this on the grass though, and if you put too much on the grassed area it will die too and take 12 months to come back...To save your grass if you burn...flood it with water 2or 3 times a day until you are completely satisfied you have diluted it enough to stop the burning of the grass....

I don't think urea's a good idea either.

Fungus do not like acid environment... but dilute the vinegar before spraying.

Fungus incontestably prefer a ph<7.0.

" The optimal substrate pH value for mycelial growth is 5-6.5, though mycelium can survive between pH 4.2 and 7.5. The mycelium grows slowly as the pH lowers and stops growing at pH 4."

I'm mainly going by the cases of swimmer's ear infections which are countered by irrigating with acidic solutions.  So the pH is the deciding factor.  We are both correct it seems.

I'm totally confused as to the advice now. I've got some hydrochloric acid. Should I dilute and spray?

 

Got poor drainage there too.

OP buy a garden fork and loosen the soil as deep as you can. Spray the dilute vinegar treatment on and wait. Buy agricultural lime and apply to these patches once a year. About 250 g per sqm and work it in with the fork. When the grass regrow use the garden fork to make holes in the lawn and apply the lime into these holes. Do this for  3 years and your problem should be solved  permanently. The vinegar is only a short term solution. The real problem is that the soul have bad drainage and is acidic. The fork will help to improve the drainage and the lime will cure the acidic nature of the soil.

Even diluted I would have thought it would solve your issue - permanently

Probably cut down on maintenance tasks as well as you would have no grass left to cut......

If you can't find Captan in a store, Lazada carries it.

Can always use Roundup as a permanent, fast and cheap cure. 555

[Foozool]

Bleach it.

Hi Badlad,

How's it coming along?....

 

[badlad]

Yes do that, if you like brown holes in your lawn.

Aw, come on mate, we come here for advice and if you disagree, ok, say so, but put some counter argument forward.

I was a qualified lawn professional and actually gave courses to  green keepers. I admit that chemicals were too readily used in the past but this fashion for insisting on using stuff out of the kitchen cupboard is ridiculous. Just because Captan has a degree of toxicity (you know, like petrol, washing powder, beer...) people are recoiling in horror when I recommend its use. Easy to apply, does the job.

Grass  prefers a slightly acidic environment as do most fungi. I doubt that many soil types in Thailand are overly acidic, most are alkaline and thus don't really need an application of lime although without measuring the pH value it's difficult to generalise.

Captan will do the job. There are other fungicides that would do it but this is the only one that I have seen in Thailand (as far as I can remember) .

Spray the whole lawn with Captan, which is judged to be harmless at normal doses.

Cheers
