Brexil® Multi is a chelated micronutrient blend in water-soluble microgranule form, designed to correct multiple nutrient deficiencies through rapid foliar absorption. It is effective across a wide range of crops including fruits, vegetables, ornamentals, and field crops.
Physical Composition and Formulation
The product is a microgranular, fully water-soluble blend of essential micronutrients. Its active ingredients are chelated (bonded) with plant-derived LigninPolyCarboxylic Acid (LPCA) or Lignin Sulfonate (LSA), which enhances stability and plant uptake. The guaranteed analysis per the product label includes:
-
Magnesium (Mg): 5%
-
Iron (Fe): 4%
-
Manganese (Mn): 4%
-
Zinc (Zn): 1.5%
-
Boron (B): 0.5%
The formulation is salt-free (contains no chlorides, sulfates, or nitrates), which minimizes the risk of phytotoxicity (plant burn).
Functional Mechanism and Design
The LPCA/LSA chelation technology is a "soft" process that protects the micronutrients, ensuring they remain soluble and available for plant absorption. This design allows for quick penetration through leaf tissues and systemic movement within the plant, providing rapid correction of visual deficiency symptoms such as chlorosis (yellowing). The product is engineered to be effective across a broad soil and spray solution pH range (pH 4-9).
Target Applications and Performance
Brexil Multi is formulated to prevent and correct deficiencies of multiple micronutrients simultaneously. It is labeled for use on a vast array of crops including pome and stone fruits, grapes, berries, vegetables (tomatoes, cucurbits, brassicas), field crops (corn, soybeans, cotton), ornamentals, and turfgrass. Its performance is noted in supporting chlorophyll production, enzyme activity, flowering, fruit set, and overall plant vigor.
Application Specifications and Protocol
The product is applied as a foliar spray. Standard application rates vary by crop type and are typically based on a concentration per volume of water.
-
Field Crops & Ornamentals: 8-32 fluid ounces per acre in 100 gallons of water.
-
Turf: 1-3 ounces per 1,000 square feet in 1-3 gallons of water.
-
Specific Crops (e.g., tomato, grape, apple): 150-300 grams per 100 liters of water, applied during growth and flowering stages.
Re-application intervals are generally 10-21 days, depending on deficiency pressure. The microgranules dissolve completely, making it suitable for all spray equipment, including aerial application. It is tank-mix compatible with most common pesticides and fertilizers.
Handling and Safety
The product is considered gentle on crops with a low phytotoxicity risk. For personal safety, applicators should wear chemical-resistant gloves during handling and mixing. The product should be stored in a cool, dry, and well-ventilated place in its original container, out of reach of children and animals. Empty containers should not be reused and must be disposed of properly.
