TREE FRUIT, TREE NUT AND OTHER CROPS

General Information

GENERAL INFORMATION

Shark EW an emulsion formulation. Shark EW is to be mixed with water, liquid fertilizer or mixtures of water and liquid fertilizer and adjuvants and applied to labeled crops for selective postemergence control of broadleaf weeds, for sucker control, for burndown prior to planting, as a harvest aid and to defoliate/desiccate labeled crops.

Weed control is optimized when the product is applied to actively growing weeds up to 4 inches in height. Shark EW is a contact herbicide. Within a few hours following application, the foliage of susceptible weeds show signs of desiccation, and in subsequent days necrosis and death of the plant occur.

Extremes in environmental conditions such as temperature, moisture, soil conditions, and cultural practices may affect the activity of Shark EW. Under warm moist conditions, herbicide symptoms may be accelerated. While under very dry conditions, the expression of herbicide symptoms may be reduced as weeds hardened off by drought are less susceptible to Shark EW.

Shark EW is rapidly absorbed through the foliage of plants. To avoid significant crop response, applications should not be made within 6 to 8 hours of either rain or irrigation or when heavy dew is present on the crop. Due to environmental conditions and with certain spray tank additives, some herbicidal symptoms may appear on the crop.

Methods of Application

Shark EW is a versatile herbicide utilizing several different application methods to achieve the desired results. If Shark is being applied in standing crop situations, application methods and adjustments must be precise to prevent undesirable effects to the desirable green stem tissue, foliage, blooms or fruit of the crops being treated.

Aerial applications are allowed in some situations. Aerial treatments must be made with a minimum of 3 gallons of total spray per acre with a minimum VMD of 450 microns.

Over-the-top applications may be utilized in some situations as noted in the individual crop directions. Spray volumes for ground applications should be 10 gallons of finished spray per acre to insure good target coverage. Spray tips must be positioned no less than 18 inches above the crop and operated in such manner as to avoid overlaps and slower than calibrated ground speeds.

Post directed applications may be utilized when labeled crops have reached minimum growth stages where sprays may be directed to the target weeds, but is not deposited on the green stem, foliage, blooms or fruit of the crop.

Hooded Sprayer applications are allowed on many labeled crops. Hooded sprayers must be designed and operated so as to totally enclose the spray nozzles and tips and spray pattern and prevent any spray deposition to the crop being treated.

Shielded Sprayer applications may be utilized in some situations. Sprayers should be designed and operated so that the shield between the spray pattern and the crop will prevent the deposition of spray to green stem plant tissue, foliage, blooms or fruit of the crop.

APPLICATION INFORMATION

GROUND APPLICATION

Use ground sprayers designed, calibrated and operated to deliver uniform spray droplets to the targeted plant or plant parts. Adjust sprayer nozzles to achieve uniform plant coverage. Overlaps and slower ground speeds (caused by continuing to spray while starting, stopping or turning) may result in higher application rates and possible crop response.

Spray Buffer for Ground Application

Spray buffer zones for ground applications, listed in chart below, are required where local indigenous endangered plant species are found.

Conventional Boom and Nozzle Sprayers

Use a boom and nozzle sprayer equipped with the appropriate nozzles, spray tips and screens and adjusted to provide optimum spray distribution and coverage at the appropriate operating pressures.

Use nozzles that produce minimal amounts of fine spray droplets. Do not exceed 30 psi spray pressure unless otherwise required by the manufacturer of drift reducing nozzles. Apply a minimum of 10 gallons of finished spray per acre. Use higher spray volumes when there is a dense weed population or crop canopy. Adjust sprayers to position spray tips no lower than 18 inches above the crop. Operate the sprayer to avoid the application of high herbicide rates directly over the rows and/or into the whorl of treated crop plants.

Directed Sprayers

For directed sprayers apply Shark EW with drop nozzles or other spray equipment capable of directing the spray to the target weeds and away from sensitive plant parts. Apply Shark EW up to the maximum rate for the target crop for the control of larger weed sizes or weeds not controlled with lower use rates. Use appropriate rates of adjuvants such as nonionic surfactants, crop oil concentrates ormethylated seed oils.

Hooded Sprayers

To apply Shark EW using a hooded sprayer, refer to the Hooded Sprayer Section on page 6 for specific adjustment and operation instructions. For additional information, refer to the individual crop sections of the label.

AERIAL APPLICATION

Use nozzle types and arrangements that will provide optimum coverage while producing a minimal amount of fine droplets. Apply at a minimum of 3 gallons of finished spray per acre. Higher aerial spray volumes are required for harvest aid and defoliation treatments. Higher spray volumes are required when there is a dense weed population or crop canopy.

Refer in the label for tank mix information.

Limitations, Restrictions, and Exceptions

TREE FRUIT, TREE NUT and OTHER CROPS

TREE SKIRT PRODUCTION SYSTEMS

Different production systems dictate different application techniques. Skirted trees are those allowing the lower branches of the trees to grow to the ground line. Non-skirted trees are grown in production systems where branches are pruned allowing access to the trunk area.

When using Shark EW in skirted production orchards/groves, the use of a hooded sprayer is required. When using Shark EW in non-skirted orchards/groves applications may be made with directed sprayers, hooded sprayers, or shielded sprayers.

Regardless of the orchard production type or the sprayer type utilized, do not allow Shark EW spray solution to contact green stem tissue, leaves, fruit or blooms of trees.

TIMING AND METHOD OF APPLICATION

Weed Control

Apply Shark EW alone or as a tank mixture with other herbicides to emerged and actively growing weeds. Apply Shark EW up to 2.0 fl. ozs. (up to 0.031 pound active ingredient) per acre, using the higher rates for larger weeds. Shark EW alone or tank mixtures may be used for general weed control, in middles (between rows of trees), and in strips (in row of trees). Shark EW may be applied at any time during the season. Shark EW may be mixed with other herbicides that have preemergence or postemergence activity. Any preemergence activity must rely on activity from other herbicides as directed on their labels. Contact herbicides such as glyphosate and paraquat may be tankmixed with Shark EW for broader spectrum weed control.

Chemical Mowing

Shark EW may be used alone or in tank mixtures with other herbicides in chemical mowing practices for orchard vegetation management.

Hooded Sprayer Applications

Shark EW may be applied with hooded sprayers to control labeled weeds between the rows of the crop. Refer to the Hooded Sprayer Applications section of the label for additional specific use directions.

Equipment and Application

Coverage is essential for good control. Use a spray volume adequate to get thorough coverage, but use a minimum of 20 gallons of finished spray per acre. Apply only with ground equipment. Applications may be made with boom equipment, hooded sprayers, shielded sprayers, hand-held and high volume wands or orchard guns. Always add Shark EW to the spray tank first. See “Mixing and Loading Instructions” under GENERAL INFORMATION.

Control is enhanced with the addition of a nonionic surfactant (NIS) or crop oil concentrate (COC). Use a nonionic surfactant (NIS) at 0.25% v/v (2 pints NIS per 100 gallons) or a crop oil concentrate at 1% v/v (one gallon COC per 100 gallons). Shark EW may also be applied with recommended rates of MSO or silicone adjuvants.

Postemergent Weed Control of Broadleaf Weeds: Apply Shark EW up to 2.0 fl. ozs. (up to 0.031 pound active ingredient) per acre for control of susceptible broadleaf weeds. The lower rate is for small seedling weeds at the 2 to 3-leaf stage; higher rates are needed for larger weeds up to the 6-leaf stage. Applications to weeds beyond the six-leaf stage may result in only partial control.

Precautions

Extreme caution must be used during applications when desirable fruit and/or foliage are present in order to avoid fruit spotting and/or leaf necrosis. Do not allow spray mist of Shark EW to come in contact with green stem tissue, foliage, blooms or desirable fruit. On seedling or newly transplanted trees do not allow spray to contact green bark of trunk area. Other herbicides may be more injurious to young trees than Shark EW. When tank mixtures are used, the precautions and restrictions on the labels of all tankmixed herbicides must be followed.

Use nozzles that will produce coarse or very coarse droplets of a Volume Median Diameter (VMD), greater than 450 microns. Do not exceed 30 psi spray pressure unless otherwise required by the manufacturer of drift reduction nozzles.

Restrictions

Do not apply more than 2.0 fl. ozs. (0.031 pound active ingredient) per acre per application and 7.9 fl. ozs. (0.124 pound active ingredient) per acre per season, including preplant site preparation.

Do not apply more than 2.0 fl. ozs. (0.031 pound active ingredient) per acre in a single application for other crops (Tropical Fruits, Kiwifruit, Pomegranate, Fig, Olive, Date, Persimmon, Banana, Cacao, Tea, Indian Mulberry, Vanilla, Coconut, Palm Heart, Coffee and Guayule).

Do not make application of Shark EW with air-blast sprayers.

Do not make applications less than 14 days apart.

Allow a minimum of three days between last application and harvest.

If Shark EW is used in a tank mixture, observe the other product’s label for restrictions, precautions, and rotational cropping instructions.

Restricted Entry Interval
