General Information

Optify is a broad-spectrum plant growth regulator. for use on field or greenhouse crops, fruits, nuts, vines and ornamentals. Optify may be applied in liquid sprays, with irrigation, or impregnated on fertilizer granules. Optimum growth effects are achieved when the product is applied on a regular scheduled application program.

Since all combinations or sequences of foliar pesticide and nutrient applications including surfactants and adjuvants have not been tested, before wide spread application, test a small area to be sprayed first to make certain that no phytotoxicity occurs.

Read the entire label before using Optify. Consult your State Agricultural Experimental Station or Extension Service Specialist for additional information on application timing, rates and any additional requirements or restrictions.

It is a violation of Federal law to use this product in a manner inconsistent with its labeling.

Do not apply this product in a way that will contact workers or other persons, either directly or through drift. For any requirements specific to your State or Tribe, consult the State or Tribal agency responsible for pesticide regulation.

Optify is a broad spectrum biopesticide to improve germination and seedling development, stimulate root and shoot growth, increase chlorophyll content, improve plant ability to withstand stress, and increase yields when used alone or in mixtures with nutrients and other pesticide products on field crops; vegetables, fruits, nuts, vine crops, turf and ornamentals.

For all crops, apply Optify at a rate of 3 to 12 ounces per acre unless otherwise specified on this label. Refer to the Foliar and Soil Application Use Rates for Outdoor and Greenhouse Crops section of this label for specific soil and foliar application use rate and timing information.

Applications can begin prior to planting for soil applications and continue as long as plants are still in the vegetative stage. Foliar applications may begin when plants reach or surpass the 4-leaf stage of development. For best results, apply Optify before leaf hardening.

Repeat applications no sooner than every 7 days. Optify is effective for use in programs where repeated applications throughout the growing season are necessary. If not applied on a routine spray schedule, apply Optify alone or in combination with appropriate fertilizers and pesticides.

Do not make foliar applications when conditions favor drift from target area or wind speed is greater than 1O mph. Spray equipment must be cleaned thoroughly before and after applications.

For foliar applications, be sure the sprayer is clean and not contaminated with other materials prior to use. When using an agitated spray tank fill tank 1/2 to 3/4 full with clean water and start agitation. Be certain that the agitation system is working properly. With the agitator running add the required amount of Optify to the tank. If tank mixing with other materials, add them to the tank and continue agitation.

Continue filling tank with the remainder of the water. Agitate until mixed thoroughly and avoid excessive foaming. Mix as needed. Do not store diluted material overnight.

For granular applications, Optify is applied to provide uniform coverage of all granules. In cases where the amount of fertilizer per acre is less than 100 pounds, Optify should be applied to a small amount of fertilizer to ensure that it will not cause the fertilizer to cake.

Optify is compatible with most commonly used agricultural pesticides. If compatibility is in question, use the compatibility jar test before mixing a whole tank. Dilute Optify to its use rate and then with stirring add the other components in the appropriate amounts. If precipitation, gelation, or sedimentation occurs, do not use the combination' of pesticides. Because of the wide variety of possible combinations that can be encountered, observe all precautions and limitations on the label of all products used in mixtures.

Apply this product only through drip, microjet, lateral move, end tow, side (wheel) roll, hand move, solid set and center pivot irrigation systems. Do not apply this product through any other type of irrigation system. Use standard tank agitation when mixing Optify alone or with other pesticides. Fill the tank halfway with water, begin agitation and add Optify, other tank mix pesticides or fertilizers and fill with water.

Preparation of Injection Equipment: Remove pesticide, scale residues and other foreign matter from the chemical tank and entire ·injection system. Flush with clean water.

Set the sprinkler system to deliver 0.1 to 0.3 inch of water per acre. Start the sprinkler system and uniformly inject the solution of Optify into the irrigation water line. Inject the Optify solution with a positive displacement pump into the main line before a right angle turn to ensure adequate mixing. If you have questions about calibration, you should contact State Extension Service specialists, equipment manufacturers or other experts.

Crop injury or lack of effectiveness in the crop can result from non-uniform distribution of treated water. A person with knowledge of the chemigation system and responsible for its operation, or under the supervision of the responsible person, shall shut down and make necessary adjustments should the need arise. The system must contain a functional check valve, vacuum relief valve, and lowpressure drain appropriately located on the irrigation pipeline to prevent water source contamination from backflow.

When applying Optify using microjet and drip irrigation systems avoid further irrigation after the treatment has been completed for 24 to 48 hours.

When applying Optify using solid set, hand move and center pivot irrigation systems avoid further irrigation of the treated area until the foliage is dry to prevent washing the product from the crop.

When applying Optify using a continuously moving system, such as lateral move, or side (wheel) roll system, inject this product-water mixture continuously, applying the labeled rate per acre for that crop.

When applying Optify through stationary or non-continuous moving systems, inject the product-water mixture in the last 15-30 minutes of each set allowing sufficient time for all the required pesticide to be applied by all the sprinkler heads and applying the labeled rate per acre for that crop.

Apply Optify continuously for the duration of the water application.

Information and Instructions for Irrigation Systems: Do not connect an irrigation system (including greenhouse systems) used for pesticide application to a public water system unless the pesticide label-prescribed safety devices for public water systems are in place.

Public system means a system for the provision to the public of piped water for human consumption if such system has at least 15 service connections or regularly serves an average of at least 25 individuals daily at least 60 days out of the year.

Irrigation systems connected to public water systems must contain a functional, reduced-pressure zone (RPZ), backflow preventer or the functional equivalent in the water supply line upstream from the point of pesticide introduction. As an option to the RPZ, the water from the public water system should be discharged into a reservoir tank prior to pesticide introduction. There shall be a complete physical break (air gap) between the outlet end of the fill pipe and the top or overflow rim of the reservoir tank of at least twice the inside diameter of the fill pipe.

The system must contain a functional check valve, vacuum relief valve, and low pressure drain appropriately located on the irrigation pipeline to prevent water source contamination from backflow. The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow of fluid back toward the injection pump. The pesticide injection pipeline must also contain a functional, normally closed, solenoid-operated valve located on the intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system is either automatically or manually shut down. The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops, or in cases where there is no water pump, when the water pressure decreases to the point where pesticides distribution is adversely affected. Systems must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm pump) effectively designed and constructed of materials that are compatible with pesticides and capable of being fitted with a system interlock. For drip (trickle) irrigation: The irrigation line or water pump must include a functional pressure switch which will stop the water pump motor when the water pressure decreases to the point where pesticide distribution is adversely affected.

Limitations, Restrictions, and Exceptions

For all crops, Optify can be applied to the soil or to the foliage. Use rates range from 3 to 12 ounces per acre for soil and foliar applications· depending upon the application method, product placement and timing. Refer to the Foliar applications and Soil applications directions hereafter for use rate and timing information.

Soil applications (including irrigation): Optify works best when soil applications are made with fertilizer or nutrient products and can be applied with liquid or granular formulations. Rates will depend upon the formulation and placement of the product. Rates are as follows:

Applied with liquid fertilizer at planting: Apply Optify at 5 to 8 ounces per acre. Recommended rates are 6 ounces per acre when applied in-furrow and 8 ounces per acre when applied in an off-set fertilizer band, such as 2 by 2 placement.
