Below is some information on a new paraquat formulation from Dr. Prostko (UGA Weed Scientist)

Syngenta recently received a label for their new formulation of paraquat sold under the trade name of Gramoxone 3SL (3 lb ai/gal).

Many rules regarding the purchase, handling, and application of paraquat are changing.  Most notably, all non-bulk paraquat products (with new labels) must adhere to closed-system packaging requirements set forth by the EPA’s Paraquat Dichloride Human Health Mitigation Decision by November 2020.  Also, all paraquat applicators are required to complete an EPA-approved training module before applying.

Here are some links for your reference

1) New Gramoxone 3SL label:

2) Current bulk handling systems already meet the new closed-system packaging requirements.  A video of the new closed system for 2.5 gallon containers can be viewed here: https://youtu.be/XNxHq_asxXg.  Tank adaptors for 2.5 gallon containers should be available from dealers and/or manufacturers?????  In my opinion, this headache will likely push more growers to bulk handling systems.

3) EPA-Approved Paraquat Training Information:

4) Generally, research results from my 2019 field trials with the new Gramoxone 3SL formulation have been very positive (see below).
