Protover is a nutritional balancer and growth cell bioactivator with fast absorption through both leaves and roots. It also functions as a means of transport for other fertilizers, micronutrients, and plant protection products. The product contains 4.9% free amino acids, 12.5% organic matter, and 2.7% total nitrogen (2.5% water-soluble nitrogen, 0.2% ammoniacal nitrogen), derived from corn protein hydrolysate. It has a density of 9.85 lb/gal (1.18 kg/L) at 68°F and a relative density of 1.16 to 1.18. The product is available in 2.5 gallon (9.46 liter) containers. It is not classified as hazardous under Regulation (EC) No 1272/2008.
Functional Mechanism
Protover acts as a biostimulant and nutrient transport aid. The free amino acids derived from corn protein hydrolysate are absorbed directly through leaf and root tissues, bypassing soil transformation. These amino acids serve as building blocks for protein synthesis, precursors for plant hormones, and chelating agents that enhance the uptake of co-applied nutrients and pesticides. The product functions as a transport mechanism, improving the penetration, absorption, and exchange of other fertilizers and plant protection products applied in mixture. Key claimed effects include: stimulation of plant growth and development; improvement of fruit size, sugar content, color, and brightness; prevention and overcoming of critical stages and adverse situations; enhancement of photosynthetic activity and protein synthesis; and increased production of auxins and enzyme regulators.

Safety and First Aid
The product is not classified as hazardous. No individual protection equipment is strictly required, though work footwear is recommended. In the application area, smoking, eating, and drinking must be prohibited.
-
Inhalation: Move victim to open air; keep warm and calm. If breathing is irregular or stops, perform artificial respiration.
-
Eye contact: Remove contact lenses if present. Wash eyes with plenty of clean, cool water for at least 10 minutes while holding eyelids open. Seek medical assistance.
-
Skin contact: Remove contaminated clothing. Wash skin vigorously with water and soap or a suitable skin cleaner. Never use solvents or thinners.
-
Ingestion: Keep calm. Never induce vomiting.
Repeated or prolonged contact may cause the removal of natural oils from the skin, leading to non-allergic contact dermatitis and absorption through the skin. Splashes in the eyes may cause irritation and reversible damage. No known acute or delayed effects from exposure to the product. In case of doubt or when symptoms persist, get medical attention. Never administer anything orally to unconscious persons.
Environmental Precautions
Do not allow product to enter sewers or waterways. Prevent penetration into the ground. Contain and collect spills with non-combustible absorbent materials (earth, sand, vermiculite, diatomite). Clean area immediately with a suitable decontaminant. Dispose of waste according to local and national regulations.
Firefighting Measures
Suitable extinguishing media include powder, CO₂, alcohol-resistant foam, and water spray. Do not use a direct stream of water. In the presence of electrical voltage, do not use water or foam. Fire can produce thick, black smoke; thermal decomposition may form carbon monoxide and carbon dioxide. Use water to cool containers close to heat source or fire.
