Context
In recent years, more and more scab-resistant (vf-gene) and/or robust apple varieties have been planted. Growers are increasingly considering sustainability and residue reduction in their choice of a new apple variety. So far, these varieties are usually treated in the same way as Jonagold, the standard variety which is sensitive against scab. Growers express their need for a modified crop protection treatment scheme for these varieties, with the aim of reducing the use of crop protection products. The operational group is focusing on the scab-resistant varieties SQ159/Magic Star® and Bonita®, the double-resistant variety T133, and the robust variety Rubis Gold®.
Activities
This project consists of four tasks. In a first task, trials will be conducted by several growers comparing the standard fungicide treatment scheme with alternative fungicide treatment schemes, either with less treatments or using biological crop protection products or plant enhancers. A second task will investigate whether reducing the number of treatments against scab and/or using alternative agents leads to an increase in other fungal diseases. The third task focuses on the follow-up of storage diseases for the different treatment schemes. Finally, the fourth task involves a cost-benefit analysis of the various treatment schemes. The results of the project will be incorporated into a technical sheet for each apple variety.

Budget information
1 Practice Abstracts
The main objective of the operational group is to develop a crop protection scheme for scab-resistant and robust apple varieties (SQ159/Magic Star®, Bonita®, Rubis Gold® and T133) with less (chemical) treatments, and without adversely affecting other fungal diseases and quality of the apples in the short and long storage. The OG also examines whether biological agents or plant enhancers are a suitable alternative to conventional fungicides. These objectives are in line with the Farm to Fork strategy within the Blue Deal, which stipulates that the use of plant protection products should be reduced by 50% by 2030 compared to 2017-2018.
