Soapy water mix.

I often get calls from customers about spots in lawns.

If its a disease most times you can see an active ring or circle.

If its muddy its obviously drowning the grass.

Next in line would be insects. I can dig for grubs but what soapy water mix works best to draw insects to the surface for id?

Not a lot of experience here. About an ounce in a 2 gallon bucket of water, my suggestion.

The first thing I would do is look around the site, look at a few soil cores, and get a feel for what's happening on the site. There are a lot of non-insect and non-disease things that can cause brown spots in lawns.

Also, go into the "investigation" knowing what diseases happen in your area at this time of year. Look for the symptoms of those diseases. Think about what the weather's been like over the last week. I hear from a ton of customers who say that 'So-and-So' lawncare company said they had 'such-and-such fungus', which doesn't make any sense because 'such-and-such' disease happens only in cool weather and we've been in the 90s for several weeks.

Similarly for insects, know what to look for before you go out there. You're probably not going to see fall insects active in late June. Then, look for the damage symptoms. Is there any leaf chewing? Can you see any inects running around? Use a soil probe or shovel to look under the surface. Do you have any insects on top of the ground or are they underneath?

I think people blame insects and diseases often simply because they don't know any better. They think that if they don't know the cause within the first few seconds after hearing about it, it must be an insect or disease and they spray it with something. Most of the time a customer or a competitor LCO think they have an insect or disease problem, but its really something like a big rock buried under the lawn or that's where the kiddie pool sat for several weeks.
