- Telzol 250 EC is a systemic preventive and curative fungicide containing 25% (w/v) propiconazole from the triazole group (FRAC Group 3). It is used to control rusts, spots, powdery mildew, and fungal leaf diseases. It is characterized by rapid absorption through the leaves and translocation within the plant via an upward systemic movement. It works by inhibiting ergosterol synthesis within fungal cells, which leads to stopping fungal growth and preventing its spread. It combines preventive and curative effects at the same time and gives the best result when used at the beginning of infection or before the disease spreads. It is considered one of the effective solutions in fungal disease control programs in field crops, vegetables, and fruit trees.
Product Features
- A fast-absorbing systemic fungicide that moves within the plant and provides effective internal protection.
- It contains propiconazole 25% from the triazole group, which is effective against a wide range of fungi.
- It works by inhibiting ergosterol synthesis, which stops the growth and spread of the fungus within the plant.
- It provides a protective effect before infection and a therapeutic effect after its appearance when used early.
- Effective in combating rusts, spots, and powdery mildew in many crops.
- It is absorbed within hours of spraying, which reduces its impact from rain after application.
- It provides protection that lasts from 10 to 14 days depending on weather conditions.
