SHELTER (Mancozeb 63% + Carbendazim 12% WP) is a widely used agricultural product that serves as a broad-spectrum fungicide and offers effective disease control for a variety of crops. SHELTER is a wettable powder (WP) formulation, and it contains two active ingredients in the following concentrations:
1. Mancozeb 63% : Mancozeb is a protective fungicide that forms a barrier on the plant's surface, preventing the establishment of fungal diseases. It is effective against a wide range of fungal pathogens, including those that cause leaf spots, blights, and other fungal diseases.
2. Carbendazim (12%) : Carbendazim is a systemic fungicide that is absorbed by the plant and provides control against internal fungal infections. It is particularly effective against diseases like powdery mildew, rust, and various root and stem rots.
1. Dosage : Consult the manufacturer's recommendations to determine the specific dosage for your crop and region. It is important to adhere to recommended application rates to avoid overuse or underuse.
2. Application : SHELTER is usually applied by mixing the wettable powder with water to create a suspension. Ensure even distribution by thorough mixing. Spray the suspension evenly on the crop foliage using appropriate spray equipment. Application is typically done during the early stages of crop growth and at regular intervals as a preventive or curative measure, depending on the presence of fungal diseases and local conditions.
3. Safety Precautions : Wear appropriate protective clothing and gear during handling and application of the product to prevent exposure to the chemicals. Read and follow the safety instructions provided on the product label.

1. Carbendazim, with systemic activity, inhibits fungal mitotic microtubule formation, disrupting cell division and impeding the development of fungal germ tubes and mycelial growth.
2. Mancozeb, working through contact action, remains on the plant surface post-spraying. Upon exposure to air, it transforms into an isothiocyanate, deactivating fungal enzymes' sulphahydral groups. This disruption interferes with the normal functioning of fungal enzymes.
