Directions for Use:
4.5% Fe EDTA is compatible with most pesticides and Orthophosphates, APP or liquid N fertilizers commonly used in “2×2” placement as a starter fertilizer, in a band, or in a broadcast application. NOTE: Foliar application alone should not be a substitute for soil application. However, if a foliar application is required, CORE 4.5% IRON EDTA may be applied 30 days after planting and before flowering to correct a deficiency. Application rates and dilution factors will vary and depend on crop sensitivity and amount of foliage to be sprayed. Dilute in a minimum of 50 gallons of water. If there is any doubt, apply the spray solution to a small test area of the crop or foliage to assess any undesirable effects or phytotoxicity before general application. Always conduct a jar test with new tank mixes to verify compatibility.
The optimum rate and timing of application will depend on local conditions and should always be made as a result of soil and/or plant tissue analysis in consultation with your local agricultural authorities. In the absence of test results, use the following as a guide:
Broadcast or Band Applications:
- Severe Deficiency 4-8 qt/acre
- Moderate Deficiency 2-4 qt/acre
- Maintenance 1-2 qt/acre
