Biological Plant Protection: Organic Anti-Fungal and Anti-Insect Treatments

Quick answer: powdery mildew, downy mildew, aphids and spider mites can be controlled without synthetic chemicals, using plant extracts like horsetail and nettle. Fertinagro Vida has a range of organic biocontrol products in liquid and powder form, designed for vegetable gardens and gardens where the goal is to avoid conventional plant protection products.

Against fungi: powdery mildew, downy mildew and leaf spots

Product Active base Format
BIO Anti-Fungal Horsetail extract (Equisetum arvense) 750 ml sprayer, preventive and curative action
BIO Anti-Fungal Powder Concentrated natural formulation 40 g sachet, shock effect against powdery mildew

Against insects: aphids, beetles and mites

BIO Anti-Insect is based on nettle extract (Urtica spp.) with preventive and curative insecticidal action, effective against aphids, beetles and other common vegetable garden pests.

Triple protection in a single product

BIO Triple Protection combines fungicidal, insecticidal and acaricidal action in a single application, also based on nettle extract. It's the practical option when you're not sure whether the problem is a fungus, an insect or mites like spider mites, or when you want a single preventive maintenance spray.

How to choose

  • You see white powder on the leaves (powdery mildew): Liquid BIO Anti-Fungal for general treatment, or the powder for a more intense shock effect.
  • You see aphids or small insects on tender shoots: BIO Anti-Insect.
  • You're not sure which pest it is, or you want to prevent several problems at once: BIO Triple Protection.

Best practices when applying organic biocontrol

  • Apply early in the morning or in the evening, never under intense direct sunlight, to avoid leaf burn.
  • Preventive action is usually more effective than waiting until the problem has advanced: apply regularly during risk periods (humid spring for fungi, budding for aphids).
  • Repeat the treatment as indicated on the label; plant-based products usually need more frequent applications than a synthetic plant protection product.
