Active ingredients and dual mode of action
Custodia combines two distinct biochemical modes of action to maximize disease suppression and manage pathogen resistance. Azoxystrobin halts spore germination by inhibiting mitochondrial respiration at the Qo site (FRAC Group 11), while Tebuconazole inhibits fungal ergosterol biosynthesis (FRAC Group 3) to halt established mycelial growth.
- Azoxystrobin (11%): Strobilurin fungicide providing preventive action and crop vitality enhancement.
- Tebuconazole (18.3%): Triazole systemic fungicide providing strong curative and eradicant performance.
- Formulation: Suspension Concentrate (SC) ensuring smooth mixing and uniform foliar adherence.
Target crops and major fungal diseases
- Paddy (rice): Blast, sheath blight, and false smut.
- Chili: Anthracnose fruit rot and powdery mildew.
- Tomato: Early blight, leaf spots, and fruit rot.
- Onion: Purple blotch and Stemphylium blight.
Application best practices and safety
Apply as a foliar spray at the initial onset of disease symptoms using clean water and calibrated knapsack or tractor-mounted sprayers. Wear personal protective equipment including gloves and goggles. Strictly comply with CIBRC label recommendations, and adhere to the specified pre-harvest interval before crop harvest.
