Best management practices - phytosanitary management in the region of Cocos-BA.

Abstract

The adoption of best agricultural practices (BAP) has the aim to guide food production in a more sustainable way. The aim of this work is to assess the impact of use BAP, mainly, in plant health, in management of forage sorghum crop. The trial was carried out in field conditions, in the municipality of Cocos, State of Bahia, Brazil, during the 2019/2020 harvest. The experiment was sowed in an area of 3 hectares. After sorghum emergence, when plants showed three expanded leaves, the area was split in three strips of 1 hectare. Each area received a distinct treatment: (1a) Integrated Management of Plagues, where were adopted BAP in all recommendations of plant health. (2a) Conventional, based on control recommendation used in the farm. (3a) Control, where none measure control after sowing was used. The definition about use of pesticides to control insects-plagues was done by weekly notes of injuries. The determination of use herbicide was done through technical visit in area assessing the infestation level and the weed community. The level of injury, caused by fall armyworm, in general, was similar between treatments. In the area of IMP only two applications were carried out, one bio insecticide and other with chemical insecticide. The conventional management was carried out with six applications, with eight chemical insecticides. It was not applied herbicide in the post-emergence of sorghum in IMP area. In conventional area was carried out one application. It was not observed difference between treatments for dry matter yield. However, IMP showed higher yield of fresh green matter. Thus, it is concluded that the adoption of BAP provides less use of pesticides, maintaining crop yield.
