Full Application Instructions

General Application Instructions:
Apply Vendra II SRX to young, actively growing grassy weeds before they exceed the growth stages listed on the product label. Weeds stressed by drought, excessive moisture, temperature, low soil fertility, mowing, mechanical injury or previous chemical treatment may respond more slowly or provide reduced control.

Thorough foliage coverage is required. Apply in 1-2 gallons of finished spray per 1,000 sq. ft. using 40-60 PSI at the nozzle tip. When weed foliage is dense, use 60 PSI and at least 2 gallons of finished spray per 1,000 sq. ft.

For ground applications, add a high-quality nonionic surfactant containing at least 75% surface-active agent at 0.25-0.5% v/v, equivalent to 0.5-1 pint per 25 gallons of finished spray. Use only a nonionic surfactant on ornamental plants. Do not use crop oil concentrate on ornamentals.Avoid mowing, hand weeding or otherwise disturbing target weeds during the 7 days before and 7 days after application. Reduced control may occur if rainfall or irrigation occurs within one hour after treatment.

Landscape and Ornamentals:
Apply 0.4-0.6 fl. oz. of Vendra II SRX per 1,000 sq. ft. in sufficient water for complete weed foliage coverage. Add a nonionic surfactant at 0.25% v/v, equivalent to 0.5 pint per 25 gallons of finished spray.Vendra II SRX may be applied over the top of ornamentals specifically listed as tolerant on the product label. It may also be used as a directed spray or spot treatment around labeled trees, shrubs, flowers and groundcovers.

Do not apply more than 0.6 fl. oz. per 1,000 sq. ft. per application. Do not make more than three applications per acre per year at the maximum rate. Do not apply more than 1.7 fl. oz. per 1,000 sq. ft. per year. Allow at least 14 days between treatments.

General Turfgrass Applications:
For suppression or control of common bermudagrass, hybrid bermudagrass and other labeled grassy weeds in zoysiagrass, tall fescue and fine fescue, apply 0.07-0.14 fl. oz. per 1,000 sq. ft. with a nonionic surfactant at 0.25% v/v.

Repeat applications every 28 days while target grasses are actively growing. Higher rates may cause temporary discoloration of desirable turf, with recovery generally occurring within 10-14 days.

Do not apply to desirable turfgrass that is stressed by heat, drought, disease, nutrient deficiency or other adverse conditions. Best results are generally obtained with spring and fall treatments. Complete control of established bermudagrass may require sequential applications over one to two growing seasons.

Bermudagrass Control in Zoysiagrass:
Apply 0.07-0.09 fl. oz. per 1,000 sq. ft. in late spring, around June 1, with a nonionic surfactant. Repeat approximately every 28-30 days as needed.

As bermudagrass prepares for dormancy in late summer, reduce the rate to 0.05-0.07 fl. oz. per 1,000 sq. ft. During hot summer weather, rates may be increased to 0.09-0.11 fl. oz. per 1,000 sq. ft. The 0.11 fl. oz. rate may cause temporary discoloration of desirable zoysiagrass.

Bermudagrass Control in Tall Fescue:
Apply 0.11-0.14 fl. oz. per 1,000 sq. ft. with a nonionic surfactant. Begin during warm weather in early spring, generally April or May, when bermudagrass is breaking dormancy.

Repeat in September or October as bermudagrass begins preparing for dormancy. Do not apply to tall fescue during the hot summer months.

Use at least 0.69 gallon of water per 1,000 sq. ft. Temporary discoloration may occur. Tall fescue should generally recover within 10-14 days.

Use Restrictions:

• Do not apply through any type of irrigation system.
• Do not apply to broadleaf weeds or sedges. Vendra II SRX controls labeled grassy weeds only.
• Do not apply more than 0.6 fl. oz. per 1,000 sq. ft. in one application.
• Do not make more than three maximum-rate applications per acre per year.
• Do not apply more than 1.7 fl. oz. per 1,000 sq. ft. per year.
• Allow at least 14 days between landscape, ornamental and noncrop applications.
• Allow at least 28 days between selective turfgrass applications. For bermudagrass turf-renovation treatments, allow at least 21 days between applications.
• Do not reseed desirable turfgrass for 14 days after treatment. Wait 30 days before seeding treated bare-ground areas.
• Do not apply to tall fescue during the summer.
• Do not allow spray drift onto susceptible turfgrass, crops or other non-target plants.
• Do not graze animals in treated areas or feed treated plants to animals.
• Keep unprotected people and domestic animals out of the treatment area during application and until sprays have dried.
