Natural protection

A <strong>naturopathic plant strengthener</strong> is a substance of natural origin — plant-based or mineral — that boosts a plant's own defences against biotic and abiotic stress. Under Italian regulations, it is a distinct legal category, separate from pesticides (which act directly on the pest) and fertilizers (which supply nutrients). It does not kill insects or cure disease: it helps the plant defend itself. <strong>Controller Funghi</strong> and <strong>Controller Afid Leader</strong> fall into this category; Controller Funghi is also approved for certified organic farming.

Yes. <strong>Neem oil</strong> is registered as a basic substance approved for use in certified organic farming (EC Reg. 834/2007, Art. 16). It is obtained by cold-pressing the fruit of <em>Azadirachta indica</em> and is rich in fatty acids and essential aromatic compounds that act against aphids, scale insects, whitefly, and other pests. Apply it as a fine spray during the cooler hours of the day, repeating treatments at regular intervals throughout the growing season. <strong>Leader Olio di Neem</strong> is formulated as a 100% plant-based, cold-extracted product.

In hobby gardening, two families of products contain copper and sulphur. The first — traditional fungicides such as Bordeaux mixture and micronised sulphur — acts directly against fungal diseases. The second rebalances mineral nutrition. <strong>Leader Rame+Zolfo Integratore</strong> belongs to this second group: a ready-to-use spray with low concentrations of copper and sulphur plus chelated iron, manganese, and zinc. It targets leaf yellowing and brown spots on roses, flowering plants, foliage plants, and vegetables.

Aphids easily colonise roses, vegetable crops, and ornamental plants. Common natural remedies include: strong water jets (physically dislodge colonies), nettle and garlic macerates (plant-based repellents), diluted Marseille soap (mechanical action on the insect cuticle), neem oil (contact and ingestion action), and natural predators such as ladybirds. Among formulated Leader products, <strong>Controller Afid</strong> combines essential oils and natural surfactants to repel aphids, whitefly, thrips, and psyllids. <strong>Leader Olio di Neem</strong> (100% plant-based) covers the same pest range plus scale insects. <strong>Tripla Azione Plus</strong> (nettle and horsetail base) works as a physical repellent in preventive mode.

Powdery mildew and downy mildew are fungal diseases that attack vines, vegetables, roses, and ornamentals. Natural prevention starts with good growing practices — pruning for airflow, adequate plant spacing, reducing humidity — and is reinforced by applying <strong>naturopathic plant strengtheners</strong> preventively: micronised sulphur (specific against powdery mildew), soya lecithin (forms a film that blocks the fungus), and horsetail extract (silica strengthens plant tissue). <strong>Leader Controller Funghi</strong> (soya lecithin, approved for organic farming) and <strong>Tripla Azione Plus</strong> (nettle and horsetail, Basic Substance with fungicidal function) both address this need.

Slugs thrive in moist conditions, so natural defence starts with keeping the area around vulnerable plants — leafy vegetables, hostas, dahlias, seedlings — as dry as possible. Common methods include physical barriers (crushed eggshells, ash, coffee grounds), beer traps, and natural predators such as hedgehogs and toads. Specific products use <strong>sepiolite</strong>, a mineral silicate with sharp-edged particles that dries the soil surface and makes passage unpleasant for slugs. <strong>Leader Controller Lumaca</strong> is a sepiolite-based barrier approved for natural cultivation: apply it as a strip around plants, and it works in pots too.
