Southern Illinois | Putting next year's chemical programs together and I am trying to determine which Group 15's to use. I have used all of them in some way shape or form and am looking for other's opinions. Now that generic Acetochlor is available, it should be coming in close to price on generic metolachlor. Dimethenamid (Outlook) and Pyroxasulfone (Zidua) are still under patent apparently so they are going to be higher. Below is my list and how I tend to use them. Looking for others opinions.
Pyroxasulfone - Anthem Maxx - Great chemical for small seeded broadleaves, had excellent luck when combined with sulfentrazone in soybeans. Needs a good activating rain (3/4") and therefore I like to use this early (pre-emerge on soybeans and early post on corn). I really like the low volume of chemical required per acre, but that is just a nice to have not a must have. No real downsides other than the price tag.
Dimethenamid - Outlook - Good chemical, especially in dryer conditions. Doesn't seem to have as long of staying power as Anthem Maxx, especially when above average rainfall. Also, price is higher than generic acetochlor and metolachlor.
Acetochlor - (Generic Warrant) - I have used this the least of all four active ingredients listed. Mostly used with resicore and in general was pleased with Resicore's performance but was hard to tell where the performance came since there are two other chemicals that both have residual benefit. Do most feel the acetochlor is doing the heavy lifting?
Metolachlor - (Generic Dual) - Decent chemical and reasonably priced especially the base metolachlor (not the s-met version). Seems to require fairly specific conditions to work best and doesn't hang around near as long as pyroxasulfone.
My plan is to probably keep 3 of these on hand and adjust my application based on ground conditions, rainfall expectations and planting date. | |
