Applications

Sprint iron chelate products are effective when directed to the root zone in soil applications, and may be incorporated mechanically or through rainfall, irrigation, soil drench or deep root feeding.

With foliar applications, a thorough cover spray to plant foliage generally provides best results. In most situations, a spray adjuvant may be added up to 0.5% by volume to ensure uniform coverage. As a general rule, Sprint iron chelate products should not be mixed with crop oil concentrates.

Sprint iron chelate products offer flexibility when tank-mixing with plant growth regulators (PGRs), as well as fertilizers that contain phosphorus or slow release nitrogen. For turf, Sprint 330 iron chelate can be tank-mixed with PGRs such as Primo Maxx. (Refer to Primo Maxx or other PGR labels for specific use directions)

Formulated as wettable powders, Sprint iron chelate products should be thoroughly mixed. If spray tank agitation is limited, premix Sprint iron chelate products in a pail until dissolved and add to the spray tank solution. Do not pre-mix Sprint iron chelate products with pesticide or fertilizer concentrates.

For use in a greenhouse irrigation system, to achieve a rate of 4 ounces Sprint per 100 gallons water, mix a concentrate stock solution consisting of 4 ounces Sprint per gallon of water. Set injector ratio to 1:100 and pump from the concentrate stock solution.

This is intended as a general guide only. Before using Sprint iron chelate products, consult the product label for specific application directions.
