Campasan Extra SL

Physiological impact and active control

The «Kamposan Extra SL» plant growth regulator from Nufarm (Austria) is a sophisticated tool designed to manipulate crop architecture. Unlike standard pesticides, it functions by regulating the plant's hormonal balance via ethephon, an ethylene-releasing agent that dictates growth patterns.

Technical Mechanism: The Ethephon Process

Once applied to the foliage, ethephon undergoes systemic metabolism, releasing ethylene within the plant tissues. This results in significant morphological changes:

• Inhibited internode elongation, lowering the plant's center of gravity.
• Strengthening of the straw base, which is critical for structural integrity.
• Balanced metabolic distribution, shifting energy away from excessive vegetative growth and toward yield formation.

Field Application Strategies

For winter wheat and barley, the primary goal of «Kamposan Extra SL» is preventing lodging. In high-yield environments where heavy nitrogen fertilization is standard, this product acts as a structural insurance policy, ensuring the stand remains upright during the grain-filling stage. In sunflower cultivation, the product is used to manage plant height, ensuring uniformity, which significantly reduces harvesting losses and improves combine efficiency.

Operational Guidelines

The formulation is delivered as a high-quality aqueous solution, ensuring stable suspension and compatibility with standard tank mixes. The application rate varies from 0.2 to 0.5 liters per hectare, contingent on the specific phenological stage of the crop. Classified under hazard class 3, the product requires standard handling precautions. Field application via spraying must ensure thorough and uniform coverage of the leaf canopy to achieve consistent hormonal distribution throughout the field. Optimal timing is crucial, as the product must be applied while the plant is still in an active phase of development to effectively modulate stem elongation.
