Project

BYDV predictor: an integrated approach to barley yellowing virus in winter grains (BYDV predicto)

The objective of the PROJECT is to develop an integrated control strategy for barley virgin virus (BYDV). This IPM approach measures to help growers to take control measures and increase their efficiency. This will provide a decision-making support within the context of the PROJECT. advisory system will be elaborated.
The PROJECT will focus on all winter cranes. Especially wheat and barley, but there will also be observations in triticale and spelt.

Disciplines:Crop science
Results:

- Various ELISA kits for detecting the virus serotypes were tested; the 'Sediag' kit is considered very efficient and together with the qPCR can serve as a basis for the detection of BYDV in practice. A qPCR test to quantify the BYDV was developed.
- A new grain aphid was described for the first time in Flanders with possible consequences for the spread of the virus RVM serotype.
- Resistance was established for the first time in S. avenae to pyrethroids in Flanders.
- Japanese oats are a good host plant for grain aphids and the BYDV.
- Resistance genes in barley to BYDV are effective but stacking of different genes will be necessary. An in vivo test to estimate the resistance level of genotypes was developed based on a qPCR.
- Two models that estimate the aphid population and thus the possible transmission of BYDV are made available to the target group via the LCG.
