A growth regulator for preventing crop lodging

Advantages

  • Prevents crop lodging.
  • Stimulates root system growth.
  • Increases plants' resistance to drought.

Characteristics

Active ingredient content
Trinexapac-ethyl, 250 g/l
Chemical group
cyclohexanediones
Formulation
emulsion concentrate
WHO classification
Class III

Recommendations for use

Application features
To enhance the growth regulation of winter rapeseed, joint application with Taler, Taler Max and Kamzol, Kamzol Turbo is recommended, which also provides long-lasting fungicidal protection. It is important to avoid spraying plants that are under stress (incl. herbicide stress), wet from dew or rain, or when precipitation is expected within the next 6 hours.
Compatibility
Not recommended for use in tank mixes with hormonal plant protection products.
Application precautions
It is not recommended to apply the product under stressful crop development conditions (autumn or spring drought, sharp differences between day and night temperatures).
Working solution pH requirements
from 5 to 7
Working solution consumption rate
200-300 l/ha

Mechanism of action

Trinexapac-ethyl acts by blocking the synthesis of gibberellins − plant growth hormones. This leads to shorter internodes, thickening of the stem and enhanced root system development.
