Armyworm theory, why me?

After looking at many yards and speaking with other turf managers in the area, we found 2 common denominators.
1.Moisture - having seen zero lawns that are dry an unirrigated that have been attacked. That tells me that when the moths fly here from "down yonder" , they lay their eggs near areas where they see succulent, soft turf tissue in wet warm soil to feed on. Would you rather eat a piece of cardboard or a juicy steak?

2.  Disease control - ALL yards that I have seen damaged so far, have been yards that had the healthiest turfgrass through late July. AKA, They had all been treated with disease control this summer and therefore had the healthiest foliage to feed on.

Conclusions - having a crappy unirrigated lawn full of weeds almost completely eliminates the risk armyworms will do damage to your lawn.

We have seen 1 case of armyworm damage in 37027. The other 11 were in 37215 or 37205. All lawns with damage have irrigation and at least 1 "overly wet" area in the lawns. My guess is these "overly wet areas" are irrigation leaks or poor drainage areas. My other guess is when the rains started coming in late July, most customers continued to irrigate on top of the rainfall.

Its just a theory......

Army worms have arrived!



Great, armyworms have arrived. As if the weeds and nutsedge aren't enough hassle! They prefer to eat Bermuda, however, they will also eat fescue seedlings, once fall seeding completed. They will eat the whole lawn seedlings in 24 hours. What about the turf insect control you applied in June? Why doesn't that kill them? We use imacloprid and bifenthrin at that time. Imacloprid will give about a years control for grubs, because it is systemic. bifenthrin gives a no quick knockdown of surface feeding turf insects that are present at time of treatment, and will also knock out fleas, ticks, chiggers, etc. However, it doesn't kill insects NOT present. Fall armyworms fly up from the gulf coast areas as moths. They don't lay their eggs in the turf. They lay eggs on fences, poles, tree limbs, etc. They have to be controlled after they arrive. They don't show up every year. Please call if you notice areas (especially bermuda) that turn brown in about 1 day, so we can stop the armyworms from doing more damage. Please watch video on other post about armyworm damage. Thanks!

Like, its not fescue time in TN!

Its hot, yo. Its wet too. Everything but fescue will grow well over next 30 days. With soil temps over 90 and afternoon showers, it sets up for ugly yards. We are spraying weeds as quickly as we can, but they will keep coming until soil temps drop in September. What you can do to help, is to make sure you are not irrigating on top of this rain. Don't even attempt to keep your fescue looking like it did even a month ago. I would rather see drought stress than pithium fungus. Brown Patch disease control won't touch pithium. Its a death nail. Hot wet soil = pithium = dead until reseed. Hot dry soil = some brown, but not dead grass that will recover quickly when soil temps cool in September. Just remember, we are not happy seeing lawns tank either. But, I bet you don't see fescue in the jungle! Bare with us, we will get weeds cleaned up and ready for fall seeding, which is less than a month away. Thank you for your patience and business. If the weeds are driving you crazy and you want ASAP spray, just call office or email. We will move you up on service call list. Thanks 6154728245

Weeds/fungus

Soil Temps increased more rapidly this May than in past several years,and we were extremely dry. During late June, early July the rains returned. Therefore, preemergent that normally dissipates in August, right before seeding season, has already dissipated. We apply the maximum legal rate of preemergent each year. We will be battling weeds now through end of August. It may take more than on visit to get them all. We are limited to what we can use because when air temps go over 90 degrees in a day, our nutsedge and weed control will also damage fescue. We will get them all cleaned up by the end of August. Please let us know if you feel you need immediate service call. What can you do to help us? If you have irrigation, make sure it runs deeply and infrequently. Make sure you don't run it more than 3 days a week. Shut it off for a couple dats if we have a heavy thunderstorm. If you have more than a few spots of nutsedge, it means the soil surface is remaining damp every day, and we won't be able to control the nutsedge as fast as it germinates. Bare with us, fall will be here soon.
