Effects of Carbaryl and Metaldehyde on Armadillidium vulgare (Crustacea: Isopoda) and Milax gagates (Mollusca: Pulmonata) in Soybean Under No-tillage

Abstract

The aim was to evaluate the control efficacy and dose of Metaldehyde 4 % + Carbaryl 8 % (2, 4 y 6 kg ha-1), Carbaryl 8 %, and Metaldehyde 4 % y 5 % (2 y 4 kg ha-1) baits on Armadillidium vulgare and Milax gagates, and to determine the number of plants and yield in soybean. The design was a randomized complete block with three replications. We evaluated the number of A. vulgare and M. gagates alive 3, 7, 10 and 16 days after application of bait (DAA), number of plants m-2, and yield (kg ha-1). The number of A. vulgare was lower with Metaldehyde 4 % + Carbaryl 8 % and with baits based on Carbaryl 8 % compared to the control at 3, 7, 10 and 16 DAA (χ2 ptrat
