Kresoxim-methyl 500 g/L WDG Fungicide | Long-Lasting Protection for Fruits, Vegetables and Specialty Crops

Kresoxim-methyl is a member of the QoI (strobilurin) fungicide group. It is widely used to control powdery mildew, scab, leaf spots and rust diseases on horticultural and specialty crops. In this formulation, the active ingredient is supplied at 500 g/L as a WDG – water-dispersible granule.

Key characteristics:

• High active ingredient load: kresoxim-methyl 500 g/L
• WDG formulation: low dust, easy to disperse, good handling
• Strong preventive and curative activity on many foliar fungal diseases
• Good penetration and local systemic movement in the treated tissue
• Long residual effect, suitable for high-value crops requiring stable protection

For B2B buyers, this means one product that can be positioned as a premium protectant fungicide with a clear story: strong on powdery mildew, strong on scab, long-lasting and ideal for programmes targeting high-value produce.

Active Ingredient and Formulation

Active ingredient

• Kresoxim-methyl – 500 g/L
• Common name: kresoxim-methyl
• Group: QoI (strobilurin) fungicide

Formulation: WDG (Water-Dispersible Granule)

Compared with WP or EC formulations, a WDG kresoxim methyl fungicide offers several advantages:

• Granules are easy to measure and pour, with much less dust during handling.
• Once added to water, they disperse rapidly into fine particles and form a stable suspension.
• The spray mix provides even coverage across both sides of the leaf and fruit surfaces.
• The packaging, storage and transport are more convenient, especially in hot climates and long-distance shipping.

These features make Kresoxim-methyl 500 g/L WDG particularly suitable for:

• Export to multiple climate zones
• Professional fruit and vegetable growers who expect high formulation quality
• Distributors who want to reduce complaints related to dust, caking and sedimentation

Mode of Action

Kresoxim-methyl belongs to the QoI (quinone outside inhibitor) group of fungicides. It acts directly on the fungal respiration process.

In simple terms:

• The fungicide binds to a specific site (Qo site) on the cytochrome bc1 complex in the mitochondria of the fungus.
• This blocks electron transport and stops energy production (ATP) inside the fungal cells.
• Without energy, fungal spores cannot germinate and hyphae cannot grow.
• The pathogen quickly stops invading new tissue and existing infections are suppressed.

Because of this mode of action, Kresoxim-methyl 500 g/L WDG provides:

• Strong protection – by preventing spore germination and early infection.
• Curative activity – by slowing and stopping early infections shortly after they start.
• Eradicant effect – by reducing sporulation and visible symptoms on infected tissue.

It also offers good translaminar and local systemic movement: after spraying, part of the active ingredient penetrates the leaf cuticle and redistributes in the treated tissue, helping to protect both sides of the leaf and new growth emerging shortly after application.

Target Diseases

Kresoxim-methyl is known for its excellent performance against several key fungal diseases, especially:

• Powdery mildew on cucumbers and other vegetables
• Apple scab and leaf spot diseases in pome fruit
• Pear scab and leaf diseases
• Rust and leaf diseases in certain specialty crops such as medicinal plants (for example Dendrobium species where registered)

These diseases can:

• Reduce leaf area and photosynthesis
• Cause fruit blemishes and quality defects
• Reduce shelf life, market value and export potential

By using a high-quality kresoxim methyl fungicide at the right timing, growers can protect plant health, maintain fruit appearance and secure higher returns on each hectare or orchard block.

Suitable Crops and Use Scenarios

Kresoxim-methyl 500 g/L WDG is positioned for use on high-value crops, including:

• Vegetables: Cucumbers and other crops where powdery mildew is a major problem (according to local registrations).
• Fruit trees: Apples, pears and other pome fruit for control of scab and leaf spots.
• Specialty crops: Certain medicinal or ornamental plants where leaf rust and leaf spots must be tightly controlled, in line with local labels.

Typical use scenarios:

• Intensive greenhouse or open-field cucumber production where powdery mildew occurs frequently.
• Professional apple and pear orchards that must meet strict appearance standards for domestic supermarkets or export markets.
• Specialty crop plantations where disease control has a direct effect on product quality and selling price.

The exact crop list, disease targets and application uses must always follow local registration and label conditions in each country.

Application Guidelines

The following guidelines are general principles to help you position the product. Actual dose rates, timing and intervals must follow the national label.

• Best results are obtained when Kresoxim-methyl 500 g/L WDG is applied preventively or at the very early stage of disease development.
• For crops such as cucumbers, sprays should be made when conditions are favourable for powdery mildew or when the first spots are seen, making sure both upper and lower leaf surfaces are evenly covered.
• For fruit trees, applications are usually timed around periods of high risk for scab and leaf spot infections, with repeat applications as allowed by the label to maintain clean foliage and fruit.
• Use clean water and maintain good agitation in the spray tank to keep the product evenly suspended.
• Choose a spray volume that ensures good coverage of foliage, shoots and, for orchards, fruit surfaces.
• Avoid spraying under extreme conditions such as strong wind, intense midday sun or when rain is expected shortly after spraying.

As with all QoI fungicides, it is important to follow resistance-management guidelines:

• Rotate kresoxim-methyl with fungicides from different modes of action, such as triazoles or multi-site protectants, as recommended in local programmes.
• Avoid repeated applications of only QoI fungicides throughout the season.

This will help maintain the long-term effectiveness of kresoxim methyl fungicide products in your market.

Frequently Asked Questions (FAQ)

What is Kresoxim-methyl 500 g/L WDG used for?
It is used as a broad-spectrum fungicide on high-value crops to control powdery mildew, scab, leaf spots and some rust diseases, depending on local registrations. It is especially valuable in cucumbers, apples, pears and certain specialty crops.

Is Kresoxim-methyl systemic?
Kresoxim-methyl has translaminar and local systemic movement. After application, part of the active ingredient penetrates the leaf and protects both the treated surface and nearby tissue, giving more complete coverage than a purely contact fungicide.

How does Kresoxim-methyl fungicide work?
It belongs to the QoI group. It blocks energy production in the mitochondria of the fungus by inhibiting electron transport at the Qo site. This stops spore germination and hyphal growth, leading to strong preventive and curative effects.

When should Kresoxim-methyl be applied?
It delivers the best results when used before disease appears or at the very early stages of infection. It should be applied according to local disease forecasting and label recommendations, usually when conditions favour disease or when the first spots are observed.

Can Kresoxim-methyl be tank mixed with other fungicides?
In many programmes, kresoxim-methyl is rotated or combined with fungicides from different mode-of-action groups to help manage resistance. Any tank mix must respect local label rules and should be tested for compatibility on a small scale before full-field use.

How long does the protection last?
Under normal conditions, kresoxim-methyl provides long residual activity, helping to protect new growth for a significant period. The exact protection time depends on disease pressure, crop growth rate and weather conditions.
