General Precautions and Restrictions
Do not apply this product within 150 feet (for aerial and air-blast application); or 25 feet (for ground applications) from marine/estuarine water bodies unless there is an untreated buffer area of that width between the area to be treated and the water body.
Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment-and-weather related factors determine the potential for spray drift. The applicator and the grower are responsible for considering all these factors when making decisions. 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 forestry applications, public health uses or to applications using dry formulations.
The distance of the outer most nozzles on the boom must not exceed 3/4 the length of the wingspan or rotor.
Nozzles must always point backward parallel with the air stream and never be pointed downwards more than 45 degrees.
Mixing, Loading, and Applying

ALWAYS APPLY THIS PRODUCT IN SUFFICIENT WATER TO OBTAIN THOROUGH, UNIFORM COVERAGE OF FOLIAGE AND CROP SURFACES INTENDED TO BE PROTECTED FROM DISEASE
Spray volume to be used will vary with crop and amount of plant growth. Spray volume should normally range from 20 to 150 gallons per acre (200 to 1400 liters per hectare) for dilute sprays and 5 to 10 gallons per acre (50 to 100 liters per hectare) for concentrate ground sprays and aircraft applications. Both ground and aircraft methods of application are recommended unless specific directions are given for a crop.
Slowly invert container several times to assure uniform mixture. Measure the required amount of Chlorothalonil 720 Select and pour into the spray tank during filling. Keep agitator running when filling spray tank and during spray operations.

Will Prime Source Chlorothalonil 720 Select cure rhizosphaera in blue spruce trees?
Prime Source Chlorothalonil 720 Select is labeled for rhizosphaera but is usually not recommended. Most Chlorothalonil based products are actually specifically labeled against use on blue spruce because they turn the trees a very unsightly white color. This is unfortunate since most online articles and local master gardeners point you specifically to Chlorothalonil based products. Because none of the products are actually labeled for blue spruce we cannot recommend you use them on these trees. If you do choose to use one, we highly recommend you choose a product that lists rhizosphaera as a disease it treats on the label. We apologize we could not be more helpful!
How many gallons of water per 1,000 square feet when using Prime Source Chlorothalonil 720 Select Leaf Spot on turf?
Prime Source Chlorothalonil 720 Selectis not labeled to be used on home lawns. Armada 50 is a great product to treat leaf spot in residential turf. You should rotate to a different class fungicide after 2 uses of the Armada. Clearys 3336F would be a great rotation partner to the Armada. The rates for each product will differe based on preventative or curative rates. You can view the Armada label and the Clearys label for rate information.
