General Information


Resistance Management
Daconil Weather Stik Flowable Fungicide is an excellent disease control agent when used according to label directions for control of a broad spectrum of plant diseases. Daconil Weather Stik Flowable Fungicide is recommended for use in programs that are compatible with the principles of Integrated Pest Management (IPM), which include the use of disease resistant plant varieties, cultural practices, pest scouting and disease forecasting systems, which reduce unnecessary applications of pesticides.

Daconil Weather Stik Flowable Fungicide is effective for strategic use in programs that attempt to minimize disease resistance to fungicides. Some other fungicides that are at risk from disease resistance exhibit a single-site mode of fungicidal action. Daconil Weather Stik Flowable Fungicide, with a multi-site mode of action, may be used to delay or prevent the development of resistance to single-site fungicides. Consult your Federal or State Cooperative Extension Service representatives for guidance on the proper use of Daconil Weather Stik Flowable Fungicide in programs which seek to minimize the occurrence of disease resistance to other fungicides.


Do not use on home lawns and turf sites associated with apartment buildings, daycare centers, playgrounds, playfields, recreational park athletic fields, athletic fields located on or next to schools (e.g., elementary, middle and high schools), campgrounds, churches, and theme parks.

Do not apply to forests.

Agricultural Use Sites: Sod farms; ornamental nurseries and greenhouses; conifer nursery beds, Christmas tree and bough production plantations, and tree seed orchards; and apricot, cherry (sweet and tart), nectarine, peach, plum and prune trees

This product must not be applied within 150 feet for aerial applications, or 25 feet for ground applications of marine/estuarine water bodies unless there is an untreated buffer area of that width between the area to be treated and the water body.

Non-Agricultural Uses
For use to control turf diseases on golf courses, on lawns around commercial (non-residential) and industrial buildings, and on professional and collegiate athletic fields.

For use to control diseases of ornamentals on golf courses and landscape areas around residential, institutional, public, com¬mercial and industrial buildings, parks, recreational areas and athletic fields.


Avoiding spray drift at the application site is the responsibility of the applicator.

Do not apply when conditions favor drift beyond the target area.

The interaction of many equipment- and weather-related factors determine the potential for spray drift.

To avoid spray drift, do not apply when the wind speed is greater than 10 mph or during periods of temperature inversions.

The following drift management requirements must be followed to avoid off target drift movement from aerial applications to agricultural field crops. These requirements do not apply to public health uses or applications using dry formulations.

1. The distance of the outermost nozzles on the boom must not exceed 3/4 the length of the wingspan or rotor.
2. Nozzles must always point backward parallel with the air stream and never be pointed downwards more than 45 degrees.

NOTE: Where states have more stringent regulations, they must be observed.

The applicator should be familiar with and take into account the information covered in the Aerial Drift Reduction Advisory Information.

Application and Calibration Techniques for Sprinkler Irrigation – Chemigation
Apply this product only through center pivot, motorized lateral move, solid set or portable (wheel move, side roll, end tow, or hand move) irrigation system(s). DO NOT apply this product through any other type of irrigation system. DO NOT use Daconil Weather Stik Flowable Fungicide through sprinkler irrigation equipment on golf courses.

Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from non-uniform distribution of treated water.

If you have questions about calibration, you should contact State Extension Service specialists, equipment manufacturers or other experts.

DO NOT apply this product through irrigation systems connected to a public water system. Public water 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 per year.

Controls for both irrigation water and pesticide injection systems must be functionally interlocked, so as to automatically terminate pesticide injection when the irrigation water pump motor stops. A person knowledgeable of the irrigation system and responsible for its operation shall be present so as to discontinue pesticide injection and make necessary adjustments, should the need arise.

The irrigation water pipeline must be fitted with a functional, automatic, quick-closing check valve to prevent the flow of treated irrigation water back toward the water source. The pipeline must also be fitted with a vacuum relief valve and low pressure drain, located between the irrigation water pump and the check valve, to prevent back-siphoning of treated irrigation water into the water source.

Always inject Daconil Weather Stik Flowable Fungicide into irrigation water after it discharges from the irrigation pump and after it passes through the check valve. Never inject pesticides into the intake line on the suction side of the pump.

Pesticide injection equipment must be fitted with a functional, normally closed, solenoid-operated valve located on the intake side of the injection pump. Interlock this valve to the power system, so as to prevent fluid from being withdrawn from the chemical supply tank when the irrigation system is either automatically or manually turned off.

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 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.

Spray mixture in the chemical supply tank must be agitated at all times, otherwise settling and uneven application may occur. DO NOT apply when wind speed favors drift beyond the area intended for treatment.

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.

Daconil Weather Stik Flowable Fungicide may be used through two basic types of sprinkler irrigation systems as outlined in Sections A and B below. Determine which type of system is in place; then refer to the appropriate directions provided for each type.

A. Center Pivot, Motorized Lateral Move and Traveling Gun Irrigation Equipment
For injection of pesticides, these continuously moving systems must use a positive displacement injection pump, of either diaphragm or piston type, constructed of materials that are compatible with pesticides and capable of being fitted with a system interlock and capable of injection at pressures approximately 2-3 times those encountered within the irrigation water line. Venturi applicator units cannot be used on these systems.

Fill chemical supply tank of injection equipment with water. Operate system for one complete revolution or run across the field, measuring time required, amount of water injected, and acreage covered.

Thoroughly mix recommended amount of Daconil Weather Stik Flowable Fungicide for acreage to be covered into the same amount of water used during calibration and inject into system continuously for one revolution or run. Mixture in the chemical supply tank must be continuously agitated during the injection run. Shut off injection equipment after one revolution or run, but continue to operate irrigation system until Daconil Weather Stik Flowable Fungicide has been cleared from last sprinkler head.

B. Solid Set and Portable (Wheel Move, Side Roll, End Tow, or Hand Move) Irrigation Equipment
With stationary systems, an effectively designed in-line Venturi applicator unit is preferred which is constructed of materials that are compatible with pesticides; however, a positive-displacement pump can also be used.

Determine acreage covered by sprinkler. Fill tank of injection equipment with water and adjust flow to use contents over a thirty to forty-five minute period. Mix desired amount of Daconil Weather Stik Flowable Fungicide for acreage to be covered with water so that the total mixture of Daconil Weather Stik Flowable Fungicide plus water in the injection tank is equal to the quantity of water used during calibration, and operate entire system at normal pressures recommended by the manufacturer of injection equipment used, for amount of time established during calibration. Agitation is recommended. Daconil Weather Stik Flowable Fungicide can be injected at the beginning or end of the irrigation cycle or as a separate application. Stop injection equipment after treatment is completed and continue to operate irrigation system until Daconil Weather Stik Flowable Fungicide has been cleared from last sprinkler head.

Limitations, Restrictions, and Exceptions

FRUIT TREES (Apricot, Cherry (Sweet and Tart), Nectarine, Peach, Plum, and Prune Trees)

DO NOT allow livestock to graze in treated areas.

Apply Daconil Weather Stik Flowable Fungicide in sufficient water (minimum of 10 gallons per acre) and with proper calibration to obtain uniform coverage of tree canopy.

Application with ground equipment is preferable to aerial application because ground applications generally give better coverage of the tree canopy.

When concentrate sprays are used or when treating non-bearing or immature trees, the lower rate of Daconil Weather Stik Flowable Fungicide listed may be used.

Application Directions
- In addition to the bloom application listed above, make one application at shuck split. DO NOT apply Daconil Weather Stik Flowable Fungicide after shuck split and before harvest. If additional disease control is needed before harvest, use another registered fungicide.
- For control of cherry leaf spot after harvest, make one application to foliage within 7 days after fruit is removed. In orchards with a history of high leaf spot incidence, make a second application 10-14 days later.

DO NOT apply more than 20.5 pints Daconil Weather Stik Flowable Fungicide (15.4 lb ai) per acre during each growing season. The minimum re-treatment interval is 10 days.

Restricted Entry Interval
