[Apple-Crop] Matrix Herbicide

[Deborah I. Breth]

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.

Take a look at the PHI.  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.

Hugh,
Thanks for the input on Chateau.  I actually regularly use Chateau.  I was thinking of using Matrix as a rotation so that I don't repeatedly use Chateau every year.

Thanks,
Matt

I don't know but look into Chateau. 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

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?

Thanks,
