Why choose Optysil Longlife?

Optysil Longlife is a modern stimulator created for professional fruit and vegetable growers who want to increase the post-harvest shelf life of their crops and improve their storage quality. Thanks to the unique duoSIL formula with the addition of organic calcium (Ca), the preparation significantly increases the mechanical resistance of fruits and vegetables, reducing the risk of damage during harvest, transport, and storage.

Studies show that its use can increase resistance to damage formation by up to 16% and extend post-harvest shelf life by an additional 16%. Moreover, the preparation improves resistance to storage diseases by as much as 24%, which translates into higher commercial value of crops and reduced losses during storage.

Technical parameters

Composition:

4.9% water-soluble silicon (Si)
22% calcium oxide (CaO) in the form of formate
1.2% copper (Cu) chelated by EDTA
1.2% manganese (Mn) chelated by EDTA
Zinc (Zn) chelated by EDTA

pH (1% solution): 4.8.

How to use Optysil Longlife?

Optysil Longlife is recommended for use in fruit and vegetable crops as foliar sprays. Application is best carried out during the formation and development of plant parts intended for harvest, such as fruits or storage organs. The preparation should be used as an aqueous solution, with the possibility of mixing with other agents – after prior compatibility testing.

During treatments, avoid strong sunlight, high temperatures, and wind that could cause drift of droplets. It is important to follow the recommended doses and use the preparation only in justified cases.

Summary

Optysil Longlife is a reliable solution for professional gardeners and orchardists who want to maximise the shelf life, quality, and resistance of their crops. Thanks to its unique formula, rich composition, and easy application, the preparation helps minimise losses during harvest and storage while increasing the commercial value of fruits and vegetables.
