PRODUCT INSTRUCTIONS AND INFORMATION
Formulation: The Parazone 3SL formulation contains 3 pounds of active ingredient per gallon. It has a strong nontoxic odor and contains an emetic which will cause vomiting if the product is accidentally swallowed. The strong odor is intentionally part of the formulation to help prevent accidental ingestion of Parazone 3SL.
Mode of Action: Parazone 3SL is a contact herbicide that is rapidly absorbed by green plant tissue. Once absorbed, the active ingredient interacts with the photosynthetic process to produce superoxides that destroy the plant cells. Parazone 3SL must be applied to green plant tissue to be effective; therefore, excellent and complete coverage of all green foliage is necessary for effective weed control and effective leaf drop, desiccation, and defoliation. Activity of Parazone 3SL is reduced when it is applied to drought-stressed weeds, weeds with little green foliage, or to the mature woody bark of trees and vines. Parazone 3SL is tied up rapidly by clay soils and organic matter so it has no residual soil activity.
Spectrum of Activity: As a contact herbicide, Parazone 3SL will control most small broadleaf and grass weeds, as well as suppress perennial weeds through the destruction of green foliage. Parazone 3SL can also be used at harvest as a desiccant or defoliant. Best weed control is achieved when Parazone 3SL is applied to emerged weeds that are still small (1 to 6 inches tall). Larger weeds are more difficult to control. Allow weeds that have been grazed or mowed to grow to 2 to 4 inches tall before applying Parazone 3SL. Also, during harvesting of forage or grain crops before spraying, weeds present in the field are also cut. Therefore, raise cutter bars as high as possible from the ground to cut stubble and weeds at a greater height allowing sufficient green foliage to remain for applications. When Parazone 3SL is used for control of grass cover crops or volunteer cereals, application must be made prior to tillering or after the boot stage especially with a wheat cover crop or volunteer wheat. Application of Parazone 3SL between tillering and the boot stage may not provide acceptable control. Parazone 3SL will not provide complete control of perennial cover crops.
