Description

Isopyrazam is a modern, systemic fungicide belonging to the chemical class of pyrazole carboxamides, widely recognized for its potent and long-lasting protective and curative activity. Its primary value lies in providing robust control against a broad spectrum of economically significant foliar diseases in major crops, enhancing yield security and quality. This product is essential for agricultural formulators and producers seeking advanced crop protection solutions for cereals, fruits, and vegetables on a global scale.

Application

• Formulation of fungicidal products for the control of Septoria leaf blotch and yellow rust in wheat and barley.
• Key component in spray programs for managing powdery mildew and scab (Venturia) in pome fruits such as apples and pears.
• Protection of banana plantations against Sigatoka leaf spot diseases.
• Disease management in grapevines, targeting powdery mildew.
• Use in oilseed rape (canola) for protection against light leaf spot and stem canker.
• Incorporation into tank mixes or pre-formulated mixtures with other fungicide modes of action for resistance management strategies.
• Technical material for the manufacturing of suspension concentrates (SC) and other commercial agrochemical formulations.
