SHIELD, WG

A Dual Approach to Solanaceous Crop Disease Control

When it comes to protecting potatoes and tomatoes from aggressive pathogens, farmers rely on integrated solutions. The fungicide "SHIELD, WG" (ЩИТ, ВГ) is a professional-grade tool that combines both contact and systemic action. Produced by Shanghai Mio Chemical Co., Ltd. and Clov (Shanghai) Co., Ltd., this product has established itself as a reliable choice for intensive farming.

Why the Combination of Active Ingredients Works

The efficacy of the product lies in the synergy of Mancozeb, Metalaxyl, and amino acid derivatives. This formulation addresses multiple biological threats simultaneously:

• Mancozeb acts as a protective barrier on the leaf surface, preventing the germination of pathogen spores (contact effect).
• Metalaxyl, belonging to the phenylamide class, penetrates plant tissues rapidly, providing both curative and protective benefits from within (systemic effect).
• Amino acid derivatives help the crop recover quickly from disease-induced stress, promoting sustained vegetative growth.

Application and Regulatory Guidelines

"SHIELD, WG" is highly effective against late blight, early blight (alternariosis), and downy mildew. Because it comes in water-dispersible granules, the product is easy to dose and dissolves quickly in water, leaving no sediment or dust in the sprayer tank.

The recommended application rate is 2.5 kg/ha. It is essential to strictly follow the regulatory framework: the maximum number of treatments per season is limited to three, and the final application must be carried out at least 14 days before harvest. Classified as a Class 3 hazard, standard safety protocols for handling modern pesticides must be observed.

This product from Chinese manufacturers occupies a strong position in the market as an affordable yet technologically advanced plant protection solution, offering farmers predictable results against fungal threats in tomato and potato cultivation.
