Works quickly and delivers uncompromised weed control all season long

Corvus 5.6 fl oz/A + 2 pt/A atrazine 20 DAT


Corvus

Application options: Burndown Early pre-plant Pre-plant incorporated Pre-emergence Early postemergence through the two-leaf (V2) growth stage


Corvus

Contains two modes of action Controls many of the weeds that are resistant to other

herbicides, such as glyphosate-, PPO- and triazine-resistant weeds

Corvus 5.6 fl oz/A + 1 lb AI/A atrazine


Corvus

Corvus can be applied in ounces per acre vs. pints or quarts per acre as required by other herbicides. Its extremely low use rate (one pass at 5.6fl oz/A) means less shipping, storage and handling, and fewer jugs.

With its rapid burndown of weeds, Corvus is perfect for any tillage program, including no-till and minimum till

Provides long-lasting residual control Translocates through the roots and shoots of weeds

Crop Safety Innovation

Corvus includes Crop Safety Innovation (CSI™) Safener technology that:

• Has both soil and foliar uptake– Makes the safener active in pre and early post

applications• Allows Corvus to be used on any soil enabling

– Greater crop compatibility – Applications through the two leaf-collar (V2) growth

stage


Crop Safety Innovation

CSI is an exclusive Bayer safener CSI changes the capacity of the plant to withstand herbicidal activity CSI safens the corn plant which has been shown to lead to increased:

Root growth Plant health

Two Modes of Action

HPPD Inhibitor: Commonly known as a bleacher Inhibits the 4-hydroxyphenylpyruvate dioxygenase (HPPD)

enzyme in plants HPPD is key to the production of protective pigments in

plants and the development of chloroplasts in plants By inhibiting pigment and chloroplast biosynthesis, emerging

plant tissue is bleached (white to pale yellow) ALS Inhibitor: Inhibition of the acetolactate synthase

enzyme Prevents the production of three essential branch-chain

amino acids These amino acids are building blocks for a plant’s normal

growth and development


Excellent Tool for the Control of Resistant Weeds

Corvus provides control of more than 50 grass and broadleaf weeds It can be a valuable tool for growers in managing weeds resistant to

glyphosate, PPO and triazine herbicides Including Corvus in herbicide programs helps growers:

Manage resistant and tolerant weed populations Maintain the viability of other herbicide programs

IPM & Resistance Management

Integrates easily into an overall pest and weed management strategy Employ practices known to limit weed development and herbicide use

(tillage, scouting and proper application timing) whenever possible Always use the full labeled rates as shown on the label Rotating herbicide mode of action is essential to improving weed

resistance management and helps you Respect the Rotation™ Rotate modes of action (MOA) and/or use multiple MOA to reduce the

selection pressure caused by overusing a single MOA Rotate herbicide-tolerant traits Rotate crops


Corvus Application Timing

Corvus is available for use in a wide variety of timing and tillage programs:

Conventional Conservation tillage No-till crop management systems Post-harvest noncrop Pre-plant Pre-plant incorporated (less than 2 inches deep) Pre-emergence Early postemergence through the two leaf-collar (V2) growth stage


Use Rates

Corvus is available for use in: Field corn production Corn grown for silage Corn grown for seed

When applied at a full rate of 5.6 fl oz/A, Corvus provides consistent one-pass weed control – all season long.

Tankmix Partners

Corvus is a strong tankmix partner for a number of herbicides, most importantly atrazine

The addition of atrazine can improve spectrum and consistency of weed control

See label for full listing of compatible herbicides and usage rates


Adjuvants - Burndown

When weeds are present at time of treatment and prior to corn emergence, tankmix Corvus with COC or MSO for burndown of labeled weeds 6 inches or less in height

When weeds are greater than 6 inches in height or weeds not controlled by Corvus are present, the addition of a non-selective herbicide is recommended

Glyphosate, Paraquat, 2, 4-D

Adjuvants - Post

Corvus is available for application to corn in a tankmix with atrazine from spiking through the two leaf-collar (V2) growth stage

Do not use COC or MSO with Corvus herbicide applied to emerged field corn

Tankmixes with other herbicides or adjuvants are not recommended for early postemergence applications of Corvus herbicide as crop response symptoms, including bleaching, leaf edge necrosis and stunting, may result.
