Now tackling the HUGE task of the Garden- viewtopic.php?f=31&t=14782 Re: Dead Patches - Empire Zoysia - Any Ideas? 11Dec 01, 2009 3:15 pm yup!! it looked exactly the same. its started small then kept spreading.we were freaking out, the grass hadnt been there long. I hadnt even heard of lawn grub till my neighbour came over and said " hey, you better fix that lawn grub up" i had never heard of it until then. we notice especially at night little moths flying around too! They are the culprits yeah we got the stuff from bunnings- its was called lawn grub killer- I think it was about $18 and it came in a bucket. but it also killed other nasties. Then we watered it in well so it soaked into the soil. You will have to reapply in about 3 weeks time to break the egg/grub cycle. it worked well though!! I suggest wear a mask though. that stuff stinks Good luck Living in Caloundra Thread****** Lovin my house all finished!!! Now tackling the HUGE task of the Garden- viewtopic.php?f=31&t=14782 Re: Dead Patches - Empire Zoysia - Any Ideas? 12Dec 01, 2009 3:34 pm I"ve just spoken to our turf supplier about the lawn grubs I saw in our rolls of turf. She advised that they have been spraying for them for a couple of weeks but if it looks like we have a problem, then they will send someone out to take a look. So ring your turf supplier - it's their responsibility.

I can tell you guys now that lawn grub is one of the biggest misled things going. Everyone goes and buys all this stuff and I can assure you it is by unbelievably massive amounts we are pouring these into the environment. Hideous quantities in the scheme of things, hideous. It is never ever lawn beetle. well in very rare cases it will be but the soil will need to be really hot and that allows their little metabolisms to go mental. Every single lawn will have lawn beetle! Everyone. Do the soapy water test, yep you have lawn beetle that's because they are always there It is the latest trend in lawns "But I put it on and I saw dead lawn beetles" of course you did, they are always there. People love the concept of buying a bag of something, putting it on and seeing dead things. The industry is based around it. 1 dead lawn beetle and 5 billion dead microflora and fauna as well as beneficial bugs for your lawn. (1 handful of soil will contain around 5 billion organisims trying very hard to make your lawn healthy) A healthy lawn will cope with lawn beetle no worries. easily in fact. professional turf surfaces can have thousands more than your lawn at home. You never see dead patches The real issue is water or fungal diseases. I was taught this very early on in my hort career and I have also attended seminars and know leading experts who also will say the same. It is of great concern to me that some companies have very underskilled horts who sell these things indiscriminately, paying little thought to the real problem. I know of one business that has a whole area dedicated to lawn beetle products and it is irresponsible in my books or they just don't understand themselves?. To kill lawn beetle you will need to do the following. 1. Apply the treatment in the morning on a sunnyday and not before irrigation. 2. 10 days later, reapply the product to kill the next life cycle of the beetle that can not be killed with the chosen chemical the first time. you will never kill the eggs and they hatch 10 days or so later and carry on with their life. 3. 10 days after that, do it again. 4. 10 days after that, do it again. Miss one of those cycles and you go back to square one. $30 a pop in some cases to do one treatment. So that is an outlay of $120 odd to get these supposed lawn destroyers under control. That is the reality of it. If you see an improvement from one application (yes you'll see dead beetles) you have achieved nothing. The lawn in many cases will recover fine even if you had not applied the treatments or at best the effects will be temporary in genuine cases. Lawn fungal diseases and soil wetability are the true causes. Often after treatment for a week or two, people pay extra attention to the lawn and give it extra water with a hose. fungus loves moisture, warmth and best of all nitrogen. All that is present in lawns right now. (there are plenty of cool season fungal diseases) this is why in my posts I give you guys alternatives to using fertilisers and avoiding much of this with strong turf and healthy soil as a result. These were never issues when water was not an issue. Have you ever seen an unhealthy lawn around a leaky tap or pipe? I bet you can put some lawn beetle stuff on in that spot and you will get a few kills anyway, but it is green lawn Spend your money on wetting agents and in particular on those areas affected or look seriously at treating your turf for various fungal diseases. that is the very first culprit please folks, stop "weeing" your money against a wall. please please understand the things in these products are really not cool for you or the soils micro ecology. It is that very ecology that makes your lawn grow well and not fertiliser All these products have to end up somewhere, they will end up in our rivers and streams resulting in fish and frog populations being affected. Do you eat the fish? It's in them. Do you live near a water catchment? it goes into the water you drink.

Things nearly done. Re: Dead Patches - Empire Zoysia - Any Ideas? 17Dec 02, 2009 9:39 pm Fu is 100% correct. The problem is 'brown patch', a fungus, not lawn grubs. It can affect any grass variety. It is a soil bourne fungus that is usually triggered by a sudden change of season and will disappear just as quick. One day lush, next day irregular silver patches, next day dead patches. Any warm season grass will grow into the damaged areas eventually and recover. Don't fertilise, don't water late pm or at night untill the areas around have started to grow into the affected regions. Other fungus problems are caused by; too much high nitrogen fertilisers in humid weather, wet leaves from night watering and blunt mower blades that will allow it to spread easily from excesively damaged leaves. There are lawn grubs/beetles everywhere, a few in a new lot of turf wont hurt anything. They're only a problem in plague proportions in sporting surfaces like bowling greens etc. This shouldn't be confused with army worms or sod web worms that can destroy the best lawn in the street overnight. This is another story, so if you see alot of moths around your outside light of a night, be ware. Re: Dead Patches - Empire Zoysia - Any Ideas? 18Dec 02, 2009 9:44 pm Thanks for the feedback grasshopper. Good to see your posts again Re: Dead Patches - Empire Zoysia - Any Ideas? 19Dec 02, 2009 9:47 pm Forgot to mention, with the dead fungus patches, rake out the dead material which will promote new growth into the area Re: Dead Patches - Empire Zoysia - Any Ideas? 20Dec 03, 2009 6:21 am Thanks for all the replies. So no watering late at night (I have been watering late arvo between 4 and 7). Should I be watering first thing in the morning then maybe? I think I will try Mancozeb if I can find it. Should I spray the whole lawn or just the effected areas. If the whole lawn, will this stuff effect the un-effected/good parts of the lawn? Thanks I would say both styles you have pictured are steel.
