Mixer/loader. An open mixing and loading system with chemical-resistant coveralls over a single layer with chemical-resistant gloves and a suitable respirator. Groundboom applicator: a closed cab with chemical-resistant coveralls over a single layer (no gloves or respirators). Aerial applicator: a single layer (long-sleeved shirt and long trousers), no gloves or respirators.
M/L = mixer/loader; A = applicator; groundboom—farmer groundboom application.
Maximum listed label application rate in g AI ha−1.
Dermal exposure = (unit exposure × area treated × rate) 70 kg−1.
Based on a dermal BMDL10 of 65.0 mg kg−1 = 6.7 mg kg−1 day−1 × 9.7 (relative rat/human dermal penetration factor) and a target MOE of 100.
