Neonicotinoids attacked in front of the State Council

JAUNDICE. State Council judges are watching this March 9 on pollination of corn. It is precisely this plant that is at the heart of the request for suspension of a decree dated February 5, 2021 for seeds coated with neonotinoids for the 2021 Beat campaign. This decree enforces a law of December 14, 2020, which opposes the prohibition of these so-called systemic pesticides, as they are present in all plant compartments. Their dangerous dangerousness on wild pollinators and honey bees had justified their ban until the jaundice virus spread by aphids threatened the 2020 beet crop.

Very persistently in the soil, neonotinoids are present in the next year’s cultivated flowering plants, which endanger the forests. Also, corn, potatoes, rapeseed, sunflowers, etc. Farming cannot be done in the next two years, leaving only farmers with a choice of wheat or barley. Hence the surprise for those attending the meeting of the Supervisory Board responsible for the monitoring and control of this re-production on January 22, 2021: an Annex authorizing the cultivation of corn the following year. “Further it contradicted the first article of the decree which prohibited flowering plants, It is surprising that Jacques Caplatt is present at the meeting as Secretary General of Agri, the e-Central Association and the agronomist himself. Representatives of beet producers took shelter behind a scientific study that showed that bees release corn only at the edge of the farm, not at the center of the plots. According to him, we could plant corn the following year if the first rows of beets were not coated seeds. “

Obscure reading of a scientific article

This study exists. It was published in the magazine Phytoma In February 2015 the grain comes from an experiment conducted by the Technical Institute of Arvalis and the Center for Biological Studies of Chizé (CNRS) in Deux-Sèvres. Bees have been set up on the edge of the field to check the bees’ weak appetite for corn. Its flowers are actually bad at pollination. Researchers have found that the presence of these pollinators is “Possible but not systematic”. But by no means is the work done that bees do not visit the centers of the plots. “According to the general rule, if harvesting has a homogeneous state (which is recommended to achieve a good level of yield), the density of bees is on average three times higher than those located in the range. Plot. Central area of ​​”, Write to researchers. This does not mean that they are absent. In particular, he observed that bee density increased rapidly in the hearts of plots when the plants located there were late in flowering. For associations, the offending measure is clearly based on poor interpretation of the study.

Seeds coated with neonotinoids are to be sown

Applicants have one more complaint to report to the judges. The law is based on the evaluation of the effects of jaundice virus on beet yield “.Incomplete and confusing “. “These are the most affected areas which have been taken into account while the yield loss ranges from 10 to 50%., Sinks Jacques Capelat. Some areas have been less affected than others and thanks to changes in agronomic practices, farmers are able to limit the action of aphids carrying the virus.“The Organic Institute for Organic Agriculture (Itab) thus confirms that farmers who have reduced the size of their plots are able to benefit from the contribution of insects feeding the aphids, thus limiting losses. This bio-control technique is also part of the measures that are recommended to fight jaundice without the use of nonnotinoids. Itab also states that the yield loss observed in 2020 is mainly due to summer drought. happened.

If the decree were to be rescinded, the Council of State would have to find that its decision was unfair. Beet producers have already purchased their coated seeds and sowing will take place during this March. Without this it is being proved that neonotinoids would be very necessary in 2021 because it is not certain that we are seeing the spread of aphids. In contrast to the very mild winter of 2019–2020, the late 2021 was marked by cold spells that delayed the emergence of aphids. This should limit their pressure on the beats.
