Product Overview

METAMORPH (Nichino Chemical India) DIMETHOMORPH 50% WP is a broad-spectrum fungicide belonging to the Phenylamide group. It is highly effective against a wide range of oomycete and fungal diseases in various crops, including vegetables, fruits, ornamentals, and field crops. METAMORPH is known for its preventive and curative action, long residual activity, and favorable crop safety profile.

Active Ingredient

METAMORPH contains dimethomorph, a phenylamide fungicide that inhibits cell wall synthesis in fungal cells, leading to their death. Dimethomorph is absorbed by the plant's roots and leaves, providing both preventive and curative control of oomycete and fungal diseases.

Mode of Action

METAMORPH acts as both a preventive and curative fungicide. Upon application to the soil or plant foliage, dimethomorph is absorbed by the plant and translocated throughout the plant tissues, providing protection against a wide range of oomycete and fungal diseases. Additionally, METAMORPH can directly contact and inhibit fungal spores, hyphae, and zoosporangia, preventing them from establishing infections.

Application Methods

METAMORPH can be applied using various methods, including:

• Foliar spraying: This involves spraying the fungicide directly onto the foliage of the plants to protect them from oomycete and fungal infections.

• Soil drenching: This method involves applying the fungicide to the soil around the base of the plant, targeting soil-borne oomycetes and fungi.

• Seed treatment: Treat seeds with the fungicide before planting to protect seedlings from early-season oomycete and fungal diseases.

• Chemigation: METAMORPH can also be applied through chemigation systems, providing even distribution of the fungicide throughout the crop field.

Application Rates

The application rate of METAMORPH varies depending on the target oomycete or fungal disease, crop type, severity of the infection, and application method. Generally, application rates range from 250 to 500 grams of product per hectare (g/ha) for foliar spraying, 500 to 1000 g/ha for soil drenching, and 5 to 10 g/ha for seed treatment.

Residual Activity

METAMORPH has a moderate residual activity, typically lasting for several weeks or months, depending on environmental conditions and the target oomycete or fungal disease. This provides effective disease control for an extended period, reducing the need for multiple fungicide applications.

Crop Safety

METAMORPH is considered safe for use on a wide range of crops, including vegetables, fruits, ornamentals, and field crops. However, it is essential to follow label directions and consult with local experts to ensure crop compatibility.

Environmental Considerations

METAMORPH is considered to have a moderate environmental impact compared to other fungicides. Dimethomorph has moderate mobility in soil, with the potential for leaching into groundwater under certain conditions. Additionally, dimethomorph has a moderate persistence in the environment, breaking down over time into non-toxic compounds.
