Cros

Mechanism of action at the cellular level

The plant growth regulator 'Kros' is based on the proven active ingredient chlormequat chloride. The preparation works by inhibiting gibberellin synthesis within wheat tissues. Practically, this prevents the plant from 'stretching' excessively during the active growth phase, redirecting energy into root system development and increasing the thickness of the stem wall.

Engineering solution for lodging resistance

A primary challenge in intensive farming, particularly with winter wheat, is the uneven development of internodes, which renders stems susceptible to breakage under high nitrogen application. 'Kros' serves as a corrective factor:

• Shortening the lower internodes — the critical junction for stem strength.
• Increasing the mechanical resistance index against wind and heavy rain.
• Synchronizing maturation processes by redistributing internal metabolites.

Application features of the product by F.Superus Co., Ltd.

The aqueous solution formulation ensures high permeability through the leaf cuticle. Classified as a Hazard Class 3 substance, it requires standard safety protocols during spraying operations. An essential factor for efficacy is the temperature regime: the effectiveness of chlormequat chloride increases during stable positive temperatures, a critical consideration when scheduling applications. The product integrates well into tank mixes, though it requires pH monitoring of the working solution to maintain the stability of the active ingredient.
