Product Group: Plant growth regulator

Very often, growers find too small and irregular sized fruits during harvest. In order to solve this problem Sitofex® is applied successfully. 

Sitofex® is a plant growth regulator that improves the fruit size and quality in various fruit crops, especially table grapes and kiwifruit.

It allows the fruit grower to increase the fruit size and consequently the production, preserving all the quality characteristics, such as the original shape of the fruit, the organoleptic features and the dry matter content.

Therefore the obtained yield is higher, together with fruits of bigger, regular size and with the best quality.

The active ingredient of Sitofex is forchlorfenuron (CPPU). It is manufactured in Germany under high quality standards including ISO 9001 and TÜV Certification. These high standards for production and handling, assure that the product will perform as indicated.

Ongoing research programs support the development of best management practices for optimizing the growth of crops under ever changing and often challenging conditions.

Sitofex® works similarly to cytokinins, which occur naturally in plants, but Sitofex® is substantially more effective. A few grams of the active substance per hectare are sufficient to achieve the desired results.

Sitofex® stimulates cell division and cell elongation and therefore induces an increase of the cell number and cell wall thickness. Under normal conditions fruit quality and shelf life are also improved.

Sitofex® is the perfect tool to manage fruit size and quality.

Sitofex® is not systemic and does not translocate within the plant. For this reason a complete and uniform coverage of the fruits is essential. Apply as a fine mist and avoid droplet formation.

Sitofex® penetrates the epidermis within approx. 6 hours. Do not apply if rain is expected and avoid applying Sitofex during the hottest hours of the day.

As Sitofex® often results in a important yield increase, fertilization and irrigation should be adjusted accordingly. Generally, the product performs best in healthy and well nourished plants.

The product rate and application time may change depending on the variety and local conditions. Please follow the indications on the label and contact your local distributor to find the best application conditions and rates in your orchard.
