Quality improvement plan for cut roses in Yunnan

Application scenario

Kunming Dounan Flower Market requires Grade A roses to have a flower head diameter of ≥8cm and be free from thrips damage. However, the traditional abamectin + gibberellin solution faces issues such as a short duration of efficacy (7 days) and a high rate of malformed flowers (15%).

Technology integration

Desheng Chemical provides an integrated solution for pest and disease control - growth regulation:

Pest control

The 1.8% abamectin-emamectin benzoate microcapsule suspension adopts a core-shell structural design:

The core is composed of avermectin (a fast-acting contact poison), while the shell is made of emamectin benzoate (a long-lasting stomach poison);

The microcapsule particle size is 2-5μm, with a slow-release period of up to 21 days, reducing the frequency of application by 50%.

Flowering period regulation

The synergistic effect of 5% gibberellin and 0.1% brassinolide compound solution through signaling pathways:

Gibberellin induces cell elongation, while brassinolide enhances the sensitivity of gibberellin receptors;

Increase the diameter of the flower head by 1.5cm, and reduce the rate of malformed flowers to below 3%.
