FRUIT AND NUT CROPS (IN ORCHARDS AND GROVES) - ALMONDS, APPLES, ETC.
Sequestrene 138 Fe Iron Chelate is a source of iron in a form readily available to plants. It can be applied as a soil application or as a foliar spray. Sequestrene 138 Fe is effective over a wide pH range, including soils where pH is 7.0 and above. Rates of application depend upon severity of deficiency, but should be kept within the recommended range for each crop.
To be absorbed from the soil, the Sequestrene 138 Fe must get into the root zone. The chelate can be placed in the root zone during planting or it can be moved into the soil by rainfall, irrigation, or tillage.

Wisconsin Users: Iron deficiency has rarely been observed on field or vegetable crops in Wisconsin, except that iron chlorosis has occasionally been observed on soybeans grown on alkaline soils (pH above 7.0). Do not use this product on any crop listed on this label unless an iron deficiency has been confirmed by plant analysis or visual deficiency symptoms. For further information on confirming iron deficiencies, contact University of Wisconsin Extension personnel.
Directions For Use
Soil applications of Sequestrene 138 Fe can be made as a drench, injected directly into the soil, or banded. For row crops, soil applications are most effective when made in a band placed in the soil at planting time, or as a side dressing shortly after plants emerge or after transplanting. Sequestrene 138 Fe can be applied alone or in combination with dry or liquid fertilizers. When treating soil around trees, apply within the drip line, and lightly incorporate into the soil or water in. Sequestrene 138 Fe can be used at any time, but application in the spring or around planting time is preferred because: (1) spring rains will move Sequestrene 138 Fe into root zone, and (2) iron will be available during the early flush of plant growth. Injection into the irrigation water provides a good after-planting method of application.
Foliar spray applications in water should be made as thorough cover sprays, carefully following the Directions For Use. Adding a small amount of wetting agent or detergent to the solution may be helpful to insure even distribution on the leaf surfaces and increase the effectiveness of foliar applications. Sequestrene 138 Fe is compatible with most commonly used 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 result from the combination spray. To facilitate mixing of the product into solution it is suggested that the required amount be added to a small amount of water and mixed until completely dissolved. The pre-mix solution can then be added, using agitation, to the final water or liquid fertilizer solution.
Almonds, Apples, Apricots, Cherries, Nectarines, Pecans, Plums, Prunes, and Walnuts
Foliage: Mix 1 to 1.5 lbs per 100 gals of water and apply as a thorough cover spray prior to bloom or after harvest. To avoid possible injury to plants, do not use in combination with oils.
