Common Name: paraquat
Formulations: 3.0L

| Amount of active ingredient | Amount by formulation |
| | 3.0L |
Per Acre | 0.25 to 1 lb. | 0.68 to 2.7 pt. |
(add 1/3 to 1/2 fl. oz. nonionic surfactant per gallon) |
Major Weeds Controlled: Nonselective control of seedling annual weeds.
Major Weeds Not Controlled: Perennials that will resprout and the following annuals are considered difficult to kill: Virginia pepperweed, lambsquarters, dayflower, filaree, horseweed, knotweed, malva, Pennsylvania smartweed, velvetleaf, fall panicum, kochia, tansy mustard, prickly lettuce, morning glory, cheatgrass, and volunteer wheat.
For Best Results: Apply to actively growing small weeds until complete coverage is obtained. Apply before plants are mowed. Use nonionic surfactant, crop oil concentrate, or methylated seed oil. May be tank mixed with other herbicides following label directions. Spray to thoroughly wet foliage but not to the point of runoff.
Cautions and Precautions: Highly toxic. This is a restricted use herbicide. Do not use around home gardens, schools, recreational parks, or playgrounds. Do not allow the spray to come in contact with bark less than one year old, green stems, fruit, or foliage of desired vegetation because injury may result. See label for additional precautions. Purchase, mixing and application of paraquat is restricted to certified applicators only. Individuals working under the direct supervision of a certified applicator are no longer able to apply paraquat. Applicators must complete a mandatory paraquat use training program provided by the US EPA every 3 years when using products with the new label requirements.
Residual Activity: No residual soil activity in mineral soils; rapidly bound by clay particles and organic matter in the soil.
Volatility and Leaching Potential: Essentially no volatility. Does not leach in mineral soils.
Symptoms and Mode of Action: Rapidly absorbed. Interacts with light to produce superoxides that destroy plant cells. On a sunny day, treated tissues will appear water-soaked within hours. Necrosis follows within one or two days. Dead tissues usually turn black.
