For use in apple, grass grown for seed, peanut, pear, strawberry, sweet cherry, and watercress

Product Information
Apogee plant growth regulator is a unique production management tool for controlling vegetative growth in the following crops: apple, grass grown for seed, peanut, pear, strawberry, sweet cherry, and watercress.

Mixing Instructions
See also: Crop-specific Additives and Tank Mixing Information. If tank mixes or additives are used, follow the rate restrictions, label recommendations, and precautions on all labels. Always follow the most restrictive label. Refer to the Additives and Tank Mixing Information crop-specific sections for additional instructions and precautions. Physical incompatibility can result from mixing Apogee with other pesticides. Test compatibility of all products
before adding them to the spray tank (see Compatibility (Jar) Test).
Compatibility (Jar) Test
• Before mixing a new combination of products or additives in the spray tank, perform a compatibility test. Begin with a quart-sized jar. Add products in the same order as the Mixing Order section. Start with 3.5 cups of water from the intended source at the source temperature. For each dry product, add 2 tsp per pound of product per acre. For each liquid product, add 1 tsp per pint of product per acre.
• Cap the jar and invert 10 cycles between component additions. • When the components have all been added to the jar, let
the solution stand for 15 minutes.
• Evaluate the solution for uniformity and stability. The spray solution should not have free oil on the surface, fine particles that precipitate to the bottom or thick (clabbered) texture. DO NOT use any spray solution that could clog spray nozzles.

Mixing Order
Maintain agitation throughout mixing.
1. Water - Fill tank 1/2 to 3/4 full with clean water and start agitation.
2. Products in PVA bags - Place any product contained in water-soluble PVA bags into the mixing tank. Wait until bags have fully dissolved and the product is evenly mixed in the spray tank before continuing.
3. Water-soluble additives - including dry and liquid fertilizer, such as ammonium sulfate or urea ammonium.
4. Water dispersible products - including dry flowables such as Apogee, dry wettable granules, suspension concentrates, or suspo-emulsions.
5. Water soluble products
6. Emulsifiable concentrates - including oil concentrates or methylated seed oil.
7. Remaining quantity of water

Application Instructions
Apply Apogee to actively growing trees with ground equipment at rates and stages listed in Tables 1-4. Apogee has been associated with an increase in fruit cracking on apple varieties known to be prone to cracking (such as Empire and Stayman).

Spray Coverage
Because Apogee is absorbed by the leaves, thorough spray coverage of the tree foliage is necessary for adequate uptake. Direct the spray to the portion of the tree where growth control is desired. To achieve thorough coverage, use sufficient water, proper spray pressure, nozzles, nozzle spacing, spray volume per acre, and tractor speed. Consult the spray nozzle and accessory guide for information pertaining to proper equipment calibration.

Timing
For vegetative growth control, make the first Apogee application in the spring when trees have 1 to 3 inches of new shoot growth. Correct timing of application is critical to success. An early first application (i.e., 1 to 2 inches of shoot growth) is more effective than a later application (i.e., 6 to 8 inches of shoot growth). If additional vegetative growth control is needed, make a sequential application before or immediately after the shoots show signs of regrowth, typically 1 to 4 weeks after the first application. Repeat applications as needed. Refer to Tables 1-3 for application rates and timings.

Number of Applications
The number of applications will vary depending on the timing of the first application, tree vigor, fruit load, pruning, variety, rootstock and/or the management history of the orchard. For apple orchards in locations with long growing seasons or higher vigor trees or trees with light fruit load, 3 to 5 applications per season can be more effective. The Apogee treatment schedule is flexible and can be applied in a number of different schedules depending on the objectives of the individual grower (see Tables 1-4). Consult with an extension specialist or consultant for your specific area.
