Princip 90 SC

Professional Systemic Protection for Orchards and Vineyards

For large-scale orchard management, maintaining the health of apple trees and vines is a constant race against fungal pathogens. «Принцип 90 SC» (Principle 90 SC) by Dow AgroSciences provides a comprehensive systemic solution, specifically designed to address the most persistent threats: powdery mildew and apple scab. Its reputation in the agricultural market is built on its dual-action capability, offering both curative and preventive control.

The Power of Formulation

The product's efficacy lies in its balanced composition, featuring Myclobutanil and Quinoxyfen. This combination acts on multiple levels of the pathogen's life cycle:

• Myclobutanil acts as a systemic agent, rapidly translocating within the plant tissues to neutralize fungal development.
• Quinoxyfen establishes a protective surface barrier, significantly hindering spore germination and preventing re-infection.

By using this systemic approach, the product remains effective even against new plant growth, providing a more reliable defense than contact-only fungicides.

Technical Guidelines and Application

Formulated as a suspension concentrate, «Принцип 90 SC» offers stability and consistent coverage during spray application. Agronomists typically recommend a dosage range of 1.0 to 2.0 liters per hectare, depending on the pressure of the infection and the stage of crop development. The protocol allows for up to 5 treatments per season, offering growers the flexibility to integrate the fungicide into a robust seasonal protection program, covering everything from early spring development to the weeks preceding harvest.

Safety and Reliability

Classified under safety class 2, this fungicide requires professional handling and adherence to safety protocols. However, for commercial fruit and grape producers, this is a standard and necessary measure to ensure high-quality yields. With its proven history as a product from the Dow AgroSciences portfolio, «Принцип 90 SC» stands as a essential tool for maintaining orchard vitality and maximizing harvest marketability.
