The lawn mix or other “dry goods” probably could be used this way. Hypothetically, you would grind the lawn mixture into a powdery substance and dissolve it in water. I guess it could either be tried to keep it all in a muddy suspension in the spray tank, or mix it up in a separate container, wait until it settles, then pour it off into your spray tank without pouring the “mud” in. A spreader-sticker additive might be considered. Of course, this is all hypothetical and should not be construed as advocacy, and I haven’t worked out any of the mix ratios for anyone either. The usual hush hush caveats apply.
They have it for lawns in liquid form also and the percentage is much higher. I did the mental math at wallyworld last year and it was a much better price that way. It definitely could be used as the ingredients were the same just the gamma-cyhalothrin content was significantly higher due to the fact it was in a hose end sprayer bottle. I didn’t see it when I was there 2 weeks ago though.
I wouldn’t try the granulized stuff, I’m sure it’s in a slow release media as they advertise it works for 3 months which is total bs…I’ve used a lot of it in the bag where it’s combined with fertilizer. That was 3 years ago and just tonight was the first time I’ve seen earthworms in my yard again.
