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.

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