SPECIAL USES - POSTHARVEST FRUIT APPLICATION
CAPTAN DRIFT LANGUAGE
SPRAY DRIFT MANAGEMENT
Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment-and-weather-related factors determines the potential for spray drift.
The applicator and the grower are responsible for considering all these factors when making decisions.
Apply only as a medium or coarser spray (ASAE standard 572) or a volume mean diameter of 300 microns or greater for spinning atomizer nozzles.
Apply only when the wind speed is 2–10 mph at the application site.
Additional requirements for aerial applications:
The boom length must not exceed 75% of the wingspan or 90% or the rotor blade diameter.
Release spray at the lowest height consistent with efficacy and flight safety. Do not release spray at a height greater than 10 feet above the crop canopy.
When applications are made with a crosswind, the swath will be displaced downwind. The applicator must compensate for this displacement at the downwind edge of the application area by adjusting the path of the aircraft upwind.
Do not make applications into temperature inversions.
Additional requirements for ground boom application:
Do not apply with a nozzle height greater than 4 feet above the crop canopy.
Where states have more stringent regulations, they should be observed.
The applicator should be familiar with and take into account the information covered in the Aerial Drift Reduction Advisory Information.
The pesticide should only be applied when the potential for drift to adjacent sensitive areas (e.g. residential areas, bodies of water, known habitat for threatened or endangered species, non-target crops) is minimal (e.g. when wind is blowing away from the sensitive areas).
COMPATIBILITY AND PLANT SAFETY
Captec 4L can be combined safely and effectively at recommended dosage rates with most commonly used fungicides and insecticides, with the exception of oil and strongly alkaline materials. Alkaline materials such as spray lime, lime-sulfur and bordeaux mixture will reduce the fungicidal activity of captan. Do not apply captan in combination with or immediately before or closely following oil sprays. The time factor governing the safe interval between captan and oil sprays varies due to general climatic conditions; therefore, consult local agricultural spray programs and authorities to determine the proper timing. The use of spreaders which cause excessive wetting is not advised. Combinations with solvent formulations of organic phosphates should not be used. Combinations of captan and sulfur should not be used on crops sensitive to sulfur. Used at high rates or in drenching sprays, captan may cause a necrotic spotting of tender, immature leaves of certain varieties of apples, peaches, plums and cherries. This type of injury is most likely to occur in the early cover sprays during long periods of warm, cloudy, humid weather. To avoid the hazard of leaf spotting under such conditions, use captan and other spray materials at lowest recommended rates and avoid drenching trees.
Applications can be made by aircraft or ground power equipment (including concentrate and semi-concentrate equipment). Pour recommended amount of this material into nearly filled spray tank. Add balance of water. Maintain agitation during filling and spraying operations. Do not allow mixture to stand. Do not combine with emulsifiable liquids or wettable powders unless previous experience has proven them to be physically compatible and safe to plants. (Read compatibility and plant safety information). For aerial or concentrate spray applications, apply the same amount of Captec 4L per acre as would normally be applied for dilute spray applications. Apply aerial or concentrate sprays in sufficient water for coverage. Do not apply this product through any type of irrigation system.
Except as specified, begin applications before or at first sign of disease and repeat as needed to maintain control but observe use limitations. Unless otherwise specified, application can be made on day of harvest. Maximum application is for a crop cycle. Crop cycle is defined as prebloom through postharvest. Apply the high rate and/or spray at shorter intervals when climatic conditions favor disease(s). Apply the low rate and/or spray at longer intervals when climatic conditions least favor disease(s). If you are unaware of the climatic conditions favorable for disease(s) claimed for the specific use sites, you must consult with your State Agricultural Extension Service to learn of these conditions.
IMPORTANT: Read label carefully. Although most of the directions on this label may be followed nationwide, a few are limited to either the eastern or western U.S. Follow those directions for your growing area where specified.
The following tables show suggested minimum spray volumes per acre; however, thorough coverage is essential for best results. The stage of growth and size are major factors in determining spray volume required to obtain thorough coverage. If there is a question regarding spray volumes needed, consult local extension service recommendations for spray volumes applicable to your particular crop.
SUGGESTED MINIMUM SPRAY VOLUMES/ACRE FOR EFFECTIVE COVERAGE
DILUTE: 100 gallons
CONCENTRATE: 50 gallons
AERIAL: 10 gallons
CAPTEC 4L RATES ARE SHOWN ON A DILUTE BASIS. UNLESS OTHERWISE SPECIFIED BY CROP, CONCENTRATE AND/OR AERIAL SPRAYS MAY BE APPLIED AT A RATE NOT TO EXCEED THAT RECOMMENDED PER ACRE FOR DILUTE SPRAYS SO LONG AS MAXIMUM RATE PER ACRE PER APPLICATION IS NOT EXCEEDED.
POSTHARVEST FRUIT APPLICATION:
For control of various molds and storage rots (Botrytis, Gleosporium, Rhizopus). Use as a postharvest dip or spray wash on the following fruits: Apples, Cherries, Pears—Use 1.25 quarts of Captec 4L per 100 gallons of water. Apply as a spray or in a dip tank. When used as a dip, recharge wash solution periodically when tank volume is reduced by 25%. Bring water back to volume and add 1.25 quarts of Captec 4L for each 100 gallons added. At end of every 8 hour shift, empty tank, flush and charge with fresh dilution. Do not allow tank solution to stand overnight. Maintain continuous agitation during dipping operation.
For use in mechanical fruit-dip operations only. Hand dipping of fruit is prohibited.
Do not contact or allow others to contact the treated fruit until sprays have dried.
DISPOSAL OF LEFTOVER POSTHARVEST TREATMENT MIXTURE:
Leftover dip or spray mixtures containing Captan may be used as a foliar spray for apples and cherries (but not pears) or to registered turf and ornamental sites, observing all restrictions such as maximum quarts applied per application and season.
When calculating application rates, if analytical services are not available to determine the exact quantity of captan remaining in mixture, assume that the tank still contains 1.25 quarts of Captec 4L per 100 gallons of water. If the dip or spray mixture contains other pesticides in addition to Captan, refer to product label(s) for information regarding disposal.
Captan wastes are acutely hazardous to the eyes. Improper disposal of spray or dip tank mixtures is a violation of Federal law. If the leftover dip or spray mixture cannot be disposed of in the manner prescribed above, contact your State Pesticide or Environmental Control Agency, or the Hazardous Waste representative at the nearest EPA Regional Offi ce for guidance concerning the disposal of spent or excess dip tank mixtures.
