Key Features

Natural pesticide - acts as a natural pesticide and fungicide, repelling certain insects and inhibiting the growth of pathogens without harming beneficial insects. Wood vinegar is less toxic than synthetic pesticides, making it an eco-friendly choice for pest control, especially in organic farming. It can be used to control a variety of pests, including aphids, mites, and slugs.

Enhancing nutrient uptake - Wood vinegar can improve soil health by stimulating beneficial microbial activity, enhancing nutrient absorption, and balancing soil pH. It promotes root growth, which helps plants take up water and nutrients more efficiently.

Boosting plant growth - Diluted wood vinegar is sometimes used as a foliar spray to stimulate plant growth and strengthen plant resilience to environmental stress. It can enhance germination rates and improve the vigor of young plants, making it popular in horticulture.

Animal Health and Hygiene - In livestock management, wood vinegar is sometimes used as an additive in animal feed for its antimicrobial properties, which can improve digestion and reduce odors. It is also used as a disinfectant in animal housing to help control bacterial growth and odors.

Composting - Wood vinegar promotes microbial activity, speeding up the breakdown of organic matter and enhancing nutrient retention. Its natural antimicrobial properties reduce odors, create a cleaner composting experience, and deter insects, ensuring a healthier and more efficient composting process that results in nutrient-rich compost for your plants.

Deodorizing - Wood Vinegar is a natural deodorizer, ideal for eliminating odors in compost bins, pet areas, and other spaces.

Disinfectant - Wood Vinegar is a natural disinfectant, perfect for cleaning and sanitizing surfaces.
