Matrix is a sulfonylurea in Group 2, and Chateau is a PPO inhibitor in Group 14. Chateau is limited to pre-bloom application because it can cause little burn spots on fruitlets if they are present and there is drift or contaminated dust that blows onto the fruitlets.

I believe that Chateau is restricted to post-harvest/pre-bloom. Matrix is something like 60 days. They both are the same class I believe.

I actually regularly use Chateau. I was thinking of using Matrix as a rotation so that I don't repeatedly use Chateau every year.

Spray it in the spring and it holds back the weeds all season. I keep it off the trunks of the trees by hand spraying a circle around each tree and then following up with a larger power hand gun sprayer at low pressure with a V tip. You will need a gram scale, the rates are crazy low, like 4 oz per acre or something... https://www.valent.com/agriculture/products/chateau/index.cfm On Thu, Mar 23, 2017 at 7:59 AM, Matt Pellerin <m...@treworgyorchards.com<mailto:m...@treworgyorchards.com>> wrote: I am considering using Matrix herbicide for weed management in my Orchard. I was wondering if anyone has used this and if you could share your experience with the effectiveness of this chemical. How does it perform as a pre-emergent and post-emergent? Spring application or fall application?
