pyraflufen-ethyl (Venue)

Pyraflufen-ethyl (Venue)
WSSA Group 14: protoporphyrinogen oxidase (PPO) inhibitor

A contact herbicide that is active on annual broadleaf weeds.
Apply when the weeds are less than 4 inches tall or 3 inches across. Use as a directed spray and thoroughly cover weeds. Use lower rates for small weeds and higher rate for larger weeds. Avoid contact with desirable foliage, green bark, or fruit. Use an approved agricultural buffering agent if using in water of equal to or greater than pH 7.5. The addition of crop oil concentrate or nonionic surfactant is recommended for optimum control. Tank mixing can increase the weed spectrum that is controlled. Mix only the amount of solution that can be sprayed within 4 hours. Do not make more than 3 applications for weed management per acre per season. Do not exceed 6.8 fl oz/acre (0.0090 lb ai/acre) per year for all
postharvest, dormant, and prebloom applications combined. Do not exceed 12.0 fl oz/acre (0.0159 lb ai/acre) per year for
all in-season applications combined. Allow at least 30 days between applications. Shield 1 year old or younger vines with non-porous wraps, grow tubes, or wax containers. Apply in a minimum of 20 gallons of water per acre.
