FAQ
A Citrus Seed Extract Biocontrol Agent is a botanical crop protection product formulated with citrus seed extract, polyphenols, biopolysaccharides, and organic matter to help suppress pathogens and support natural plant defense mechanisms.
Citrus seed extract contains naturally occurring bioactive compounds that can help create an unfavorable environment for certain pathogens while supporting the plant's natural defense responses.
Botanical-based products may be suitable for certain organic farming systems, but organic certification and permitted-use requirements vary by country. Always verify the applicable local organic standards and product certification before use.
It can be used as part of crop protection programs for fruit trees, vegetables, fruit and berry crops, field crops, and greenhouse crops, subject to local registration and approved crop uses.
Botanical biocontrol agents can provide a plant-based approach to crop protection while supporting plant defense and helping reduce pathogen pressure. They can also complement integrated pest and disease management programs.
Yes. The formulation is designed to help activate natural plant defense responses. Its polyphenols and biopolysaccharides contribute to the product's botanical and biological activity.
Preventive application or application during the early stages of pathogen pressure is generally preferred. For best results, timing and frequency should follow the product label, target crop, local disease pressure, and applicable agricultural regulations.
