Question 14335 — environment

Summary

Mr. Martial Saddier draws the attention of the Minister of Agriculture and Food to the issue of ragweed. 1.2 million French people are victims of allergies to the pollen of this species which is growing rapidly in 2018 and which causes problems of loss of biodiversity due to its invasive nature. Ragweed easily colonizes any non-vegetated space. This is why it develops particularly in plots agricultural crops and more particularly in spring crops with low coverage such as sunflowers. The issue of weeding sunflower plots is essential so that producers can continue to have satisfactory yields and quality production. A reduction in surface area has already been observed, which is causing bee starvation. Indeed, the sunflower is one of the main honey crops. 60 % of French honey production depends on rapeseed and sunflower. It is therefore the entire beekeeping sector which is today worried about its future and that of the pollination service. Farmers must also benefit from advanced agronomic support: sowing under cover, extending rotations, shifting sowing dates, etc. Finally, tomorrow's solutions will be the result of scientific and technical research. If biological control of ragweed is not yet possible today, it may be possible tomorrow thanks to the mobilization of research. Also, he asks how the Government intends to sustainably ensure farmers have access to all the means of combating ragweed and support them in the field: manual uprooting, hoeing of crops, use of tolerant sunflower varieties allowing weeding. selective in post-emergence (VTH), establishment of false seedlings.
