Pyrus 400 SC

Pyrus 400 SC is a systemic fungicide formulated as a soluble concentrate (SC) designed for the protection of pome fruit crops, particularly apples and pears. It provides effective control of foliar diseases such as powdery mildew and scab through both preventive and curative action. Details

Description

Active Ingredients (indicative):
• Total active content: 400 g/l – for example, a synergistic blend of 200 g/l cyprodinil and 200 g/l tebuconazole
(Please refer to the label for exact details.)

Mode of Action:

  • Systemic and Translaminar: Once applied, Pyrus 400 SC is rapidly absorbed and evenly translocated throughout the plant, protecting both the treated areas and new growth.
  • Dual Action:
    • Cyprodinil disrupts the synthesis of essential proteins, interfering with the metabolic processes of fungal pathogens.
    • Tebuconazole inhibits sterol biosynthesis, compromising the integrity of the fungal cell membrane and preventing growth and sporulation.
  • Synergistic Effect: The combination of the two active ingredients delivers broad-spectrum disease control while reducing the risk of resistance development.

Usage Instructions (example):

  1. Preparation:
    • Dilute Pyrus 400 SC in water according to the label instructions (e.g., 200–400 L/ha) to obtain a uniform spray solution.
  2. Application:
    • Apply as a foliar spray ensuring complete coverage of the crop (e.g., apples and pears).
    • The product can be used preventively or curatively at the first signs of disease, with reapplications every 14–21 days depending on environmental conditions and disease pressure.
  3. Precautions:
    • Follow the label recommendations regarding dosage and pre-harvest intervals.
    • Conduct compatibility tests if tank mixing with other products.

Advantages:

  • Provides effective control of foliar diseases in pome fruit crops.
  • Systemic and translaminar action ensures comprehensive plant protection.
  • The dual active combination minimizes the risk of resistance development and offers broad-spectrum control.
