Great post. Loved the photos. Since organics is about promoting life in the soil, it appears you still have some! Surprisingly, Tru-Green didn't wipe them out.
I've read compost is an effective control on pests because many pests don't like diversity in the soil. Our chinch bugs here are said to hate a moist compost when applied to Saint Augustine. Where are your birds? Mine would be chowing down on those bugs you got there. Otherwise, try molasses, or try on the spot control with garlic-pepper tea applied through a sprayer. That will kill the pests (and beneficial insects) but not the grass.

Live in Apopka and also have St. Augustine. Healthy soil is key! You want to increase the microbial diversity in the soil. You can never go wrong adding compost to our sandy Florida soil. But just as important is the addition of a liquid soil amendment/ conditioner containing humic acids and root hormones to name a few ingredients. The micronutrients they provide aid in drought and pest resistance while encouraging root development. I have personally been using organic products on my lawn for over a year and this is the first year in four that I have not had to resod major portions of my lawn - unlike my wonderful but chemically dependent neighbors.

While I hate to copy a url and paste it, I don't mind helping others with the code to fix their posting. Here's your message with links to the images. I tried embedding the images into the message but they are huge. Much faster to link to them.

If you want to skip the story, just look at the last picture. I need help finding an organic way to control these! Thanks!

Well, I just bought my first house a couple months ago and it turns out the giant headache was included. The lawn was in horrid condition. Prior to buying the house, the well pump was broken and the owners had given up on watering the nice St. Augustine lawn. They also stopped their tru-green service. Ever wonder how a St. Augustine lawn looks when you stop watering it in florida(before the rain comes) and stop using pesticides? Its not pretty. Some of the lawn was salvageable with watering(the well was fixed when I moved in). Bringing the lawn back was a daunting task and I had no idea where to start. I have since found Garden Web and the Oragnic Lawn Care forum. I have started on once section of my lawn, a small corner under the old oak tree.

Per suggestions found in this forum, I have top dressed the area with a little less than 1/2" compost, put down 10lb/1,000ft soybean meal, continued watering once a week around 5am, and I continue to mow high.

Within the past month, the rain has really picked up. There was three day stretch in which every night around 8pm it rained 1"+. All this water didnt help out my lawn. It quickly developed grey leaf spot that spread to my entire nice green corner section.

I have since attacked it with the recommended dose of Actinovate, still awaiting results.

There are more probelms. There is a section of this corner that has developed some odd charecteristics. It all started out as a small 1'x1' patch of turf that looked like it had thatch problems. It has since grown into a monster. Here is a close up.

The patch of this is now about 6'x8' and its not pretty.

I was about to ignore it and assume it was "end stage grey leaf spot" as the fungus was pretty extensive. That was until I got down on my hands and knees and took a closer look

It sems something has been muching on my soft green blades. And honestly, what little critter wouldnt want to?

So now that the leaf spot will soon be under control (pending Actinovate effectiveness and use of corn meal 10-20lb/1,000ft) How do I figure out who's visiting the all you can eat buffet?

I couldnt find any suspects, other than a couple of these guys(spittlebug)

So now I ask for everyones help! Where do I start? How do I figure out who has their hand (or multiple hands) in the cookie jar?

Update: Well, I went out to take a larger picture so everyone could see the shape/area involved. Something didnt add up so I put in some more 'hands and knees' time. Guess who I found? Take a look below

The organic answer you are looking for is called BT worm killer. It works immediately to stop the caterpillars from feeding. It might take four days for them to die but once you stop them from eating, that's all you care about. It is sold by Safer and by Green Light. One application is all you need.
