Statistics of actual use of the top
We also recorded bird first-tier TERlt for insectivorous, herbivorous, and granivorous bird scenarios as well as higher-tier TERlt when available in the reports.
3.1. Potential exposure of clutches to single active substances
Partridge clutches (n = 140 clutches, > 1600 eggs) were exposed to 108 ASs during pre-laying, laying, and incubation phases over Valdecoxib total of 179 ASs used between 1st March and 31st August 2010 and 2011 (84 herbicides, 4 herbicide safeners, 58 fungicides, 20 insecticides, 7 plant growth regulators, 2 molluscicides, 2 acaricides, 1 anti-sprouting, and 1 bird repellent. Some ASs were also defoliants.) (Table 1, Appendix A). 71.4% of the clutches were exposed to at least one AS. The proportion of clutches potentially exposed to a sieve cells given AS was ≥ 5% for 32 ASs. These “top” ASs were mainly fungicides (n = 17, 53.1%). Herbicides represented 25% of top ASs, insecticides 15.6% and growth regulators 6.2%.
