The combined use of spray volumes and droplet sizes in the chemical control of Asian soybean rust in cultivars with different leaf area indices

Autor: Bruna Piton, Magda Ribeiro da Luz, Carlos Alberto Forcelini, Walter Boller, Carolina Cardoso Deuner, Amanda Chechi, Rafael Roehrig

Publikováno v: Crop Protection. 136:105212

Asian soybean rust (ASR) is the principal disease that affects the soybean crop. Fungicides are most effective in controlling ASR. However, the intrinsic factors related to the soybean cultivar, suitability of the application technology to the target
