SHORT-STAPLE AND LONG-STAPLE (PIMA) COTTON - HIGH RATE - THIRD APPLICATION - EXCESSIVE GROWTH EXPECTED
Mepiquat Chloride 4.2% Liquid is a foliar applied plant regulator. Benefits derived from the use of this product include increased boll retention, reduced plant height which provides a more open canopy, less boll rot, improved defoliation, less trash, and darker leaf color. These benefits can provide for earlier maturity and often result in improved yields.
Growers may use single or multiple applications. Application rates per acre are dependent on the number of applications to be made and growing conditions. Multiple applications of low rates provide maximum flexibility under a wide range of growing conditions. This product should not be applied to plants under stress. If stress is alleviated, plants should be evaluated for vegetative growth before additional applications are made. This product may be tank mixed with insecticides/miticides when application timings coincide. (See RESTRICTIONS AND LIMITATIONS.)
Fields should be carefully scouted. This product should not be applied if plants are under any form of stress. In the absence of stress, a maximum of five low rate applications can be made each season. The first application can be applied at the matchhead square stage. The rate and timing of subsequent applications depend on growing conditions and desired benefits. Under good growing conditions, additional treatments (2 – 4 fl. oz. per acre) can be made at 7-14 day intervals. The higher rates (4 – 12 fl. oz. per acre) should be used if growth is excessive. Do not use more than a total of 48 fl. oz. of Mepiquat Chloride 4.2% Liquid per acre in a growing season.
LATE SEASON APPLICATION:
Application during the 4th to 6th week of blooming can reduce late season growth or re-growth after cutout or defoliation and can allow more complete and manageable cutout, better defoliation, earlier maturity, and reduction in trash. Do not make a late season application if cotton is stressed. Rank cotton may not respond well to late season application.
Apply after cutout when re-growth begins, usually 5 to 6 weeks after the first bloom.
TIMING FOR LATE SEASON APPLICATION:
1. For control of re-growth after cutout, apply Mepiquat Chloride 4.2% Liquid when re-growth begins, usually 5-6 weeks after first bloom.
2. If cotton never completely cuts out and growth is too vigorous, apply Mepiquat Chloride 4.2% Liquid when there are 4-6 nodes above the white flower.
USE RATE FOR LATE SEASON APPLICATION:
Apply 8 – 24 fl. oz. per acre. Use low rates on moderately growing cotton and high rates on vigorously growing cotton. Do not exceed 48 fl. oz. per acre of Mepiquat Chloride 4.2% Liquid during the total growing season.
Areas other than California:
Ground Application – Use a minimum of 2 gallons/acre.
Aerial Application – Use a minimum of 2 gallons/acre.
Ground Application – Use a minimum of 5 gallons/acre.
Aerial Application – Use a minimum of 5 gallons/acre.
Use a minimum total oil volume of 2 pints/acre for Ultra Low Volume (ULV) aerial application. Application in oil is permitted only in AL, AR, FL, GA, KS, LA, MO, MS, NC, OK, SC, TN and TX. Use a nonphytotoxic oil concentrate which contains either a petroleum or vegetable oil base, contains only EPA-exempt ingredients, and has been used successfully in your locality. The oil diluent should contain emulsifiers which provide good mixing quality. If using a vegetable oil based product, only highly refined concentrates should be used. Mix under constant agitation. Pour one half of the required volume of oil into the spray tank, and then pour in the Mepiquat Chloride 4.2% Liquid while the remainder of the oil is added. Constant agitation is required during and after mixing and during application.
RAIN WASH-OFF PRECAUTION:
The use of a high-quality, EPA-exempt surfactant will enhance the uptake of Mepiquat Chloride 4.2% Liquid into the plant. Therefore, the use of a surfactant allows applications made as little as 4 hours prior to rainfall to be effective. Without a surfactant, the product should be used at least 8 hours prior to expected rainfall.

SHORT-STAPLE AND LONG-STAPLE (PIMA) COTTON
LOW RATE MULTIPLE APPLICATIONS:
Use the instructions when you want to maintain maximum flexibility in plant regulation treatments.
Excessive Growth Expected or Higher Rates Have Been Necessary in the Past
Fourth Application: 7-14 days later, or when re-growth occurs.
Use the higher rate if previous application was not made or if growing conditions favor excessive growth.
