"Weed control: physical, mechanical, cultural, biological and allelopathy methods" is the title of the book launched by the Brazilian Agricultural Research Company (Embrapa) and is available for free download
in the "Publications" section of the company portal. According to one of the technical editors, researcher Maurílio Fernandes de Oliveira, from the area of Embrapa Maize and Sorghum, the book is the first national work to address weed control by non-chemical methods, "assisting organic producers, agro-ecological and the academy itself."
The publication has 10 chapters, focusing on weed control methods, such as scrubbing, electrocution, use of cover crops, natural herbicides, biological control, soil solarization, and flaming, among others. In total, 30 experts are authors of the work, which provides a description of techniques tested and available for use and by techniques in development, based on biological principles, mechanics, mulching and allelopathy.
In the preface, Embrapa Milho and Sorgo's chief of staff, Antônio Álvaro Corsetti Purcino, says that the first objective of the work "was to produce national literature addressing weed control methods for use in organic agriculture and agroecology." According to him, the book contributes to the topic with literature complementary to the chemical method, which is widely studied and researched. "We detected that the non-chemical control of weeds demands the effort of the scientific community both in the production of control technologies and in the results of the use of these technologies," he concludes.
In addition to the researcher Maurílio Fernandes de Oliveira, the researcher is Alexandre Magno Brighenti, from the field of Phytotechnology of Embrapa Dairy Cattle (Juiz de Fora, MG). The other authors represent teaching, research and extension institutions, such as several Embrapa Units and universities.
