Seqostar

Iron Chelate Micronutrients

High Performance Iron Chelates for Foliar and Soil Applications

General Product Information

Iron is essential for the formation of chlorophyll, a vital component to ensure plant health. Since iron has low plant mobility, new growth in iron deficient plants often shows iron deficiency. In early stages, leaves have interveinal chlorosis where plant leaves are light green to yellow but the leaf veins remain green. In severe cases, leaves turn white and plants may die.

Iron deficiencies commonly occur in:

• Soils which are high in pH, calcareous, or have heavy clay which tie up iron.

• Plants which have a limited root system due to environmental, pest, or disease stress.

• Soils high in sand content due to poor nutrient holding capacity.

Astrachem’s Seqostar chelated micronutrient formulations are important to plant health. Unlike non chelated or weakly chelated irons, Seqostar is strong chelates that maintain and protect iron availability in a wide variety of problem soils.

Plus, Seqostar has the added flexibility for either foliar or soil applications. Sequestrene 330, a 10 percent fully chelated DTPA iron, performs best in slightly acid to slightly alkaline soils with a pH of up to 7.5.

Seqostar , a 6.5 percent fully chelated EDDHA iron, is preferred in the most challenging soils that are alkaline and calcareous, including soils with a pH greater than 7.0. Sequestrene 138 provides the strongest chelate available for these difficult situations.

Seqostar Rates and Applications

Tank Mixes with Pesticides:

The outstanding chelating ability of Seqostar allows excellent tank mixing flexibility, including mixing with insecticides and fungicides and can be applied in combination with them. However, because available pesticide combinations differ so widely, before applying chelate-pesticide combinations to large crop areas a small test area should be sprayed to determine that no phytotoxicity or undesirable effects results from the combination spray. Seqostar is formulated as a wettable powder. If spray tank agitation is limited, Seqostar may be pre-mixed in a pail until dissolved, then added to the spray tank. Do not pre-mix Seqostar with pesticide or fertilizer concentrates. This posting is intended as a general guide only. Before using Seqostar , the product label should be consulted for specific application directions.
