Contaf (Rallis India Limited) is a post-emergent, systemic herbicide with the active ingredients hexaconazole (5%) and captan (70%). It is used to control a wide range of fungal diseases on a variety of crops, including fruits, vegetables, and ornamentals.

Mode of action:

• Hexaconazole is a triazole fungicide that inhibits the synthesis of ergosterol, a key component of fungal cell membranes. This weakens the cell membrane and kills the fungus.
• Captan is a multi-site fungicide that attacks the fungus at multiple points, including disrupting cell division, inhibiting respiration, and interfering with enzyme function. This makes it difficult for the fungus to develop resistance to captan.

Application:

Contaf can be applied as a foliar spray using a conventional sprayer. The application rate depends on the type of crop being grown and the fungal disease being controlled. For example, to control powdery mildew on apples, the application rate is 0.25-0.5 L/ha. To control late blight on potato, the application rate is 0.75-1 L/ha.

Benefits:

• Contaf is a highly effective fungicide that provides broad-spectrum control of a wide range of fungal diseases.
• It is also relatively safe for humans and animals, and it has a short pre-harvest interval, making it a good choice for use on crops that are about to be harvested.
