Companion is a broad-spectrum combination fungicide developed by Indofil Industries Ltd. for the control and prevention of fungal diseases in various crops, including vegetables, fruits, and ornamentals. It contains a combination of two active ingredients: Mancozeb 63% and Carbendazim 12%. Mancozeb is a contact fungicide that works by disrupting the respiration process of fungal cells, while Carbendazim is a systemic fungicide that is absorbed into the plant and moves throughout the plant, providing protection against fungal infections.

Mode of Action

The combination of Mancozeb and Carbendazim in Companion provides both protective and curative action against a wide range of fungal diseases. Mancozeb acts as a contact fungicide, forming a protective barrier on the surface of plant tissues, preventing fungal spores from germinating and infecting the plant. Carbendazim, on the other hand, is a systemic fungicide that is absorbed into the plant and moves through its vascular system, providing protection from the inside out.

Key Features and Benefits

Companion offers several advantages that make it a popular choice among farmers:

• Broad-spectrum efficacy: Effective against a wide range of fungal diseases, including early and late blight, leaf spot, powdery mildew, and downy mildew.
• Protective and curative action: Prevents fungal infections and eradicates existing ones, providing comprehensive disease control.
• Multisite action: Reduces the risk of resistance development in fungal pathogens.
• Safe for a variety of crops: Can be used on a wide range of vegetables, fruits, and ornamentals without causing phytotoxicity.

Application Guidelines

Companion is typically applied as a foliar spray, ensuring thorough coverage of all plant parts. The recommended dosage varies depending on the crop and the severity of the fungal infection. Generally, a concentration of 250-500 grams per hectare is recommended. Repeat applications may be necessary at intervals of 7-10 days, depending on disease pressure and weather conditions.

Safety Considerations

Companion is classified as moderately toxic, so it is essential to follow safety precautions during handling and application:

• Wear personal protective equipment (PPE), including gloves, a mask, and overalls.
• Avoid direct contact with skin and eyes.
• Do not apply during hot or windy conditions.
• Dispose of empty containers and unused products responsibly.

Overall, Companion is a versatile and effective fungicide that provides broad-spectrum protection against a wide range of fungal diseases in various crops. Its combination of protective and curative action, along with its multisite activity, makes it a valuable tool for farmers seeking to maintain healthy and productive crops.

In addition to the above, here are some other important points to note about Companion:

• Pre-harvest interval (PHI): The PHI varies depending on the crop, but it is generally between 7 and 14 days. This means that the last application of Companion should be made at least 7-14 days before the crop is harvested.
• Storage: Companion should be stored in a cool, dry place away from direct sunlight.
• Compatibility: Companion is compatible with most other pesticides, but it is always a good idea to test for compatibility before mixing.
