Cresolsulfonate-methyl

Kresoxim-methyl is a systemic fungicide belonging to the strobilurin class, characterized by its translaminar properties and ability to form stable residues on the plant surface.

The core mechanism of action involves the inhibition of mitochondrial respiration in fungi by binding to the Q0 site of the cytochrome b-c1 complex, which effectively shuts down ATP production.

It acts both as a preventative and a curative agent, preventing spore germination and the development of hyphae during the early stages of fungal colonization.

The substance is known for its excellent rain-fastness, as it binds to the waxy layer of the leaf, providing durable protection even in high-moisture environments.

Beyond its primary function, kresoxim-methyl is known to improve crop vitality and delay leaf senescence, contributing to better yields and crop quality.

This active ingredient shows significant activity against a broad range of pathogenic fungi, including Ascomycetes, Basidiomycetes, and Deuteromycetes.

• Powdery mildew in fruits and vegetables
• Apple and pear scab (Venturia spp.)
• Rust and leaf spot diseases in cereals
• Grapevine downy and powdery mildew
• Various leaf blights

Kresoxim-methyl is an essential tool in managing fungicide resistance, as it performs well against pathogens that are no longer controlled by older chemistries.

It is widely utilized in integrated pest management (IPM) programs to minimize the impact of severe fungal epidemics on crop productivity.

The versatility of this fungicide allows for its application on various horticultural and cereal crops, providing a comprehensive disease management strategy.

The recommended application rates vary from 100g to 400g of active ingredient per hectare, depending on the crop type and the pathogen pressure level.

Applications should ideally be timed during the early stages of disease development to maximize the preventative efficacy of the treatment.

A typical interval between applications ranges from 10 to 14 days, though it may be adjusted based on local weather conditions and disease forecast data.

Proper calibration of spraying equipment is vital to ensure optimal coverage and canopy penetration for effective disease suppression.

To preserve long-term efficacy, it is highly recommended to rotate products containing kresoxim-methyl with fungicides of different modes of action.

Compatibility with other pesticides should always be verified through a jar test before mixing to prevent chemical degradation or physical incompatibility.

Operators must adhere to strict safety protocols, including wearing appropriate PPE, to minimize dermal and inhalation exposure during handling.

Due to its high toxicity to aquatic life, all application drift must be kept away from streams, rivers, and ponds to protect local ecosystems.

Strict adherence to pre-harvest intervals is mandatory to ensure that residues on the harvested produce remain well below the regulated maximum levels.

Storage must be in a cool, dry, and well-ventilated area, safely away from food, feed, and water supplies to prevent cross-contamination.
