| ABSTRACT: The selectivity of eight herbicides registered for use in the wheat crop was assessed on the predators Chrysoperla externa and Eriopis connexa. Bioassays were conducted in the laboratory by exposing larvae, eggs, and pupae of these predators to dry residues of the herbicides 2,4-D amine, bentazon, glyphosate 1.200, glyphosate 1.440, ammonium glufosinate, iodosulfuron-methyl, metsulfuron-methyl, and pyrimidinedione. The herbicide ammonium glufosinate was classified as moderately harmful (class 3) to the larval stage of both predators. In the egg stage, only metsulfuron-methyl showed a reduction in larval hatching higher than 30% and was classified as slightly harmful (class 2) to eggs of E. connexa. The herbicide 2,4-D amine was classified as... |

| ABSTRACT: The use of pesticide mixtures constitutes a relatively common practice in rice crops. Thus, the aim of this work was to evaluate the physicochemical interaction among different pesticide tank mixes for use in paddy field rice. The study has followed technical standards specified in ABNT [Associação Brasileira de Normas Técnicas (Brazilian National Standards Organization)] NBR [Norma Brasileira Regulamentadora (Brazilian Regulatory Standard)] NBR 13875:2014 for the assessment of physicochemical compatibility by means of a dynamic technique. Treatments consisted of mixtures of 12 pesticides, which constituted 16 treatments, six of which are composed by mixing herbicides, six by mixing herbicide and insecticide, one by mixing fungicides, and three... |
