Now that dursban and diaznon are gone, what is the chemical of choice?
I'm assuming you're interested in surface feeders like Chinchbugs & webworms. For this Talstar (bifenthrin) is the new king.
A coulple years ago, it looked like DeltaGard would wear the crown for surface feeder insect control. But formulation challenges combined with FMC's very agressive price reductions of Talstar have derailed that one.
Talstar Flowable is the available liquid:
Talstar EZ is a PCO/LCO straight granular:
Talstar+Fertilizer combinations abound (this is one of many):
Without Diazinon & Sevin (won't be long now), there won't be anymore silver bullets that will control Grubs & Chinchbug with one molecule. The synthetic pyrethroids don't irrigate into the rootzone where they can control grubs. And Merit & Mach2 are both lame on Chinchbugs. Though Mach2 at least does a very nice job on lepidoptera, it has trouble with chafer & oriental grubs.
Alas, we now have to sell 2 bags where one used to get the job done.
Hope this helps.
As far as Talstar goes, I LOVE it. I'd recommend it to anyone. The lack of odor is something nice too! Tremor knows his stuff.
Thanks for the reply. Our main problem lawn pest is crane fly and talstar will do the job.
Now one more question what about fruit trees the label says talstar is not to be used.
Astro is labeled for bearing trees. True Ag labels are goofy in the residential setting because of the Worker Re-entry statements. But this will be OK.
If you still have Malathion or any of several formulations of Sevin, you can legally use thos too.
Sevin has worked very well for me in Canada.
Tremor, great work. Thank-you.
Just getting my lic in applications is there a bible on the control chems.
I know very general....
I wish I could refer folks to a book that would somehow remain current. There are plenty of great books that can help with insect & disease ID. But to publish a good text book & have it become obsolete everytime a liberal politician makes the White House would't work out.
Check for the titles in this similar thread.
They rarely delve into control strategies with respect to actual chemical names. But that's OK. PP Pirone recommends chemicals in his very good shade tree book. But the list of chemicals is laughable today. Many are no longer being made. And many better ones have been introduced since the otherwise good text was last published. And still, several times a year, I have to "reeducate" someone about modern control products because they treat Pirones book like the Bible.
Once certified, all states require applicators to mantain their lisence by attending accredited seminars. You will stay abreast of new molecules at these seminars, trades shows, from reputable dealers, & places like here.
