Sphinx Extra

Engineering plant protection: the mechanics of «Sphinx Extra»

The efficacy of the «Sphinx Extra» fungicide from Makhteshim Chemical Works Ltd. is built on the synergy of two active ingredients: dimethomorph and folpet. Unlike mono-component treatments, this combination attacks pathogens on two fronts simultaneously, which is essential for managing resistance.

Composition and Action Mechanics:

• Dimethomorph (morpholines): responsible for systemic activity. It disrupts the synthesis of the fungal cell wall during all stages—spore germination, mycelial growth, and sporulation. This allows the product to penetrate deep into plant tissues, making it highly effective against late blight and downy mildew.
• Folpet (phthalimides): serves as a potent contact «shield». It suppresses fungal enzymes, inhibiting respiration and cell division. Its presence on the leaf surface provides protection against external infection while the systemic component works internally.

Technical Application Guidelines:

The product is formulated as water-dispersible granules, ensuring dust-free handling during tank mixing and high suspension stability. With a dosage rate ranging from 2.0 to 3.0 kg/ha, the product achieves optimal coverage of the leaf surface, which is critical for dense foliage like tomatoes or potatoes.

Due to its systemic nature, it effectively protects grapes from downy mildew and manages rot complexes on vegetables. The 30-day pre-harvest interval and a maximum of 3 treatments per season ensure the active ingredients are fully metabolized, maintaining compliance with safety standards for agricultural produce.
