GENERAL INFORMATION


Valtera EZ Herbicide provides residual control of susceptible weeds in soybean, field corn, spring and winter wheat, chickpea, field pea, lentils [small red and large green varieties], sunflower and to maintain bare ground non-crop areas on farms when used in accordance with this label. It also may be used as a harvest aid for crop subgroup 6C dried shelled pea and bean [including bean (Lupinus spp.), bean (Phaseolus spp.), bean (Vigna spp.), broad bean [fava bean], chickpea, guar, lablab bean, lentil, pea (Pisum spp.), pigeon pea (excluding soybean)] and wheat. Valtera EZ Herbicide is effective as a preemergence herbicide, for control of selected grass and broadleaf weeds. Valtera EZ Herbicide controls weeds by inhibiting protoporphyrinogen oxidase, an essential enzyme required by plants for chlorophyll biosynthesis. Seedling weeds are controlled preemergence when exposed to sunlight following contact with the soil applied herbicide. Preemergence weed control with Valtera EZ Herbicide is most effective when applied to clean, weed-free soil surfaces.
Disturbing soil surfaces may reduce herbicide efficacy.
Valtera EZ Herbicide offers residual control of susceptible grass and broadleaf weeds listed on this label and assists in the control of acetolactate synthase (ALS) resistant weeds. The length of residual control is dependent on the application rate as well as on rainfall and temperature conditions. Length of residual control will decrease as temperature and precipitation increase and on soils of high organic matter and/or high clay content.

GENERAL DIRECTIONS FOR USE


As this pesticide is not registered for the control of pests in aquatic systems, DO NOT use to control aquatic pests.
DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.

SPRAYER AND APPLICATION INFORMATION
Shake Valtera EZ Herbicide well before use.
Apply using ground application equipment only. Before applying Valtera EZ Herbicide, start with clean, well-maintained application equipment. Nozzles should be uniformly spaced on boom and frequently checked for accuracy. For broadcast application, apply Valtera EZ Herbicide with ground equipment using standard commercial sprayers equipped with nozzles designed to deliver the desired spray pressure and spray volume.
When banding, use proportionately less water and Valtera EZ Herbicide per hectare.
Equipment with Valtera EZ Herbicide residues remaining in the system may result in crop injury to the subsequently treated crop. Spray equipment used to apply Valtera EZ Herbicide should not be used to apply other materials to any plant foliage. Spray equipment must be cleaned each day following Valtera EZ Herbicide application. After Valtera EZ Herbicide is applied, the following steps must be used to clean the spray equipment:
1. Completely drain the spray tank, rinse the sprayer thoroughly, including the inside and outside of the tank and all in-line screens. Fill the spray tank with clean water and flush all hoses, booms, screens and nozzles.
2. Top off tank, add 4 L of 3% household ammonia for every 400 L of water, circulate through sprayer for 5 minutes, and then flush all hoses, booms, screens and nozzles for a minimum of 15 minutes.
3. Drain tank completely.
4. Add enough clean water to the spray tank to allow all hoses, booms, screens and nozzles to be flushed for 3 minutes.
5. Remove all nozzles and screens and rinse them with clean water.
6. Do not contaminate water, food or feed by cleaning of equipment.

MIXING INSTRUCTIONS
1. Fill clean spray tank 1/2 to 2/3 of desired level with clean water. Engage gentle agitation.
2. While agitating, slowly add Valtera EZ Herbicide to the spray tank. Agitation should create a rippling or rolling action on the water surface.
3. If tank mixing Valtera EZ Herbicide with other labelled herbicides follow the WAMLEGS [Wettable powders/ flowable, Agitate Anti-flowing compounds/buffers, Microcapsule suspension, Liquid and soluble, Emulsifiable concentrates, High load Glyphosates, Surfactants] mixing order system:
• Add water soluble bags first
• Followed by dry formulations, flowables, emulsifiable concentrates and then solutions.
• Prepare no more spray mixture than is required for the immediate spray operation.
4. Add adjuvants or surfactants, if recommended.
5. Fill spray tank to desired level with water. Agitation should continue until spray solution has been applied.
6. Mix only the amount of spray solution that can be applied the day of mixing.
Valtera EZ Herbicide should be applied within 6 hours of mixing.

CARRIER VOLUME AND SPRAY PRESSURE
Preemergence Application: To ensure uniform coverage, use between 100 to 300 L of spray solution per hectare for preemergence applications. Use higher water volumes if significant crop residue is present. Nozzle selection should meet manufacturer's volume and pressure recommendations for preemergence herbicide application.
Harvest Aid Application: To ensure thorough coverage in harvest aid applications, use 140 to 280 L per hectare. Nozzle selection should meet manufacturer's volume and pressure recommendations for postemergence herbicide application. Do not use flood jet nozzles.
Apply the spray mixture uniformly with properly calibrated ground equipment only.
Ensure thorough coverage and a uniform spray pattern. Use 50 mesh filter screens or larger (metal or nylon). A spray pressure of 210 - 275 kPa is recommended for flat fan nozzles.
Field sprayer application: DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE S572.1) medium classification. Boom height must be 60 cm or less above the crop or ground.
Use caution when applying under circumstances where possible drift to unprotected persons or food, forage or other plantings that might be damaged or crops thereof rendered unfit for sale, use or consumption can occur.
Use the largest droplet size consistent with acceptable efficacy. Formation of very small droplets may be minimized by appropriate nozzle selection, by orienting nozzles away from the air stream as much pressure.
Make application when the wind velocity favours on-target product deposition.
Do not make applications during temperature inversions. Inversions are characterized by stable air and increasing temperatures with increasing distance above the ground. Mist or fog may indicate the presence of an inversion in humid areas. Where permissible by local regulations, the applicator may detect the presence of an inversion by producing smoke and observing a smoke layer near the ground surface.
Low humidity and high temperatures increase the evaporation rate of spray droplets and therefore the likelihood of increased spray drift. Avoid spraying during conditions of low humidity and/or high temperatures.
All ground application equipment must be properly maintained and calibrated using appropriate carriers.
DO NOT apply by air.
