Do not mix with alkaline pesticides.
Thiram decomposes easily under alkaline conditions, reducing effectiveness.
Apply strictly according to recommended dosage.
Overuse may cause phytotoxicity or inhibit crop growth.
Wear protective equipment during handling.
Use gloves, masks, and goggles to avoid direct skin contact or inhalation of spray mist.
Avoid spraying under high temperature or strong sunlight.
Apply in the early morning or late afternoon to ensure maximum efficacy.
Keep away from water sources, feed, and food storage areas.
Wash hands and equipment thoroughly after use. Do not discharge residues into rivers or ponds.
Safe storage.
Store in a cool, dry, and well-ventilated place, out of reach of children and pets.
Hazard to bees and aquatic organisms.
Avoid spraying near beekeeping areas or during crop flowering; prevent water contamination.
