Ponduard 1L bottle


Pondguard is an Essential Oil blend obtained from a mixture of three plant oil extracts: Lavender, Pine, and Eucalyptus. The active components Cineol, Linalool, and Isobornyl acetate have anti-viral and anti-bacterial activities. Pondguard in lower doses acts as an immunomodulator by which animals can keep their immune system at the optimum level. Pondguard was formulated by using novel innovative techniques developed by Rhea. In addition, several carriers, like minerals in feed premix, dilution in water, and salt, have been used to create this product. Pondguard helps to enhance productivity by keeping the Feed-Conversion-Ratio (FCR) at the minimum level in both shrimp and fish.

Pondguard is effective against deadly pathogens of shrimp, like white spot syndrome virus (WSSV), Infectious Myonecrosis Virus (IMNV), Acute Haepatopancreatic Necrotic Disease (AHPND), and pathogenic Vibrio of shrimp and Iridovirus, Viral Nervous Necrosis, Streptococcus and Aeromonas of fish. Rhea Natural Sciences has developed Pondguard which is widely used in aquatic farms in Indonesia, India, Vietnam, China and Saudi Arabia.

Pondguard is comprised of ingredients from 3 essential oils:

Pinus sylvestris

Isobornyl acetate is an active component extracted from Pinus oil. Amongst other components, it has been known for a long time for its anti-microbial activities.

Lavandula latifolia

Linalool is an active component extracted from Lavandula oil. The immunomodulatory properties and antimicrobial properties of have been well documented, even against multidrug-resistant Staphylococcus aureus strains.

Eucalyptus globulus

Cineole is an active component extracted from Eucalyptus oil. Essential oil extracted from various Eucalyptus plant species contain many pharmacologically active compounds which are useful as antimicrobial agents. Essential oil ingredients from Eucalyptus species were reported to possess antimicrobial activity especially against emerging multidrug-resistant bacterial strains such as MRSA, which makes them attractive alternatives to standard antibiotics. Eucalyptus oil and its major ingredient 1,8-cineole were evaluated as natural disinfectants and found to be comparable and synergistic with standard chemical disinfectants.
