Evaluation of cotton stalks destroyers

Abstract: ABSTRACT:The destruction of the cotton crop residues (cotton stalks) is a mandatory procedure in Brazil for prophylactic issues, but is a subject unexplored by the research and there are few studies that deal with this issue. However, this is not encouraged in recent decades, studies aimed at developing and evaluating equipment for this purpose. The present study had the objective to evaluate six methods for mechanical destruction of cotton crop residues. Each method was defined based on the principle of opera… Show more

“…Cotton stalk destruction after harvest is a very important strategy of the integrated pest management (Lima et al, 2013;Grigolli et al, 2015). After harvest, crop residues and stalks can be eliminated by soil tillage implements such as plow and plowing harrow (Bianchini & Borges, 2013;Ribeiro et al, 2015;Sofiatti et al, 2015), although devices have been developed to improve the operational capacity of the destruction and promote minimum soil mobilization (Sofiatti et al, 2015). Nevertheless, this form of destruction, besides having low operational efficiency, does not always conform to the principles of the no-till system (NTS), a conservation system that favors the mitigation of greenhouse gases (Corbeels et al, 2016;Sant-Anna et al, 2017).…”

“…Portanto, a destruição dos restos dessa cultura é uma importante prática cultural para o manejo de populações remanescentes do bicudo e de outras pragas, como a broca-da-raiz [Eutinobothrus brasiliensis Hambleton (Coleoptera: Curculionidae)]; pulgão [Aphis gossypii Glover, 1877 (Hemiptera: Aphididae)]; mosca-branca [Bemisia tabaci Gennadius, 1889 (Hemiptera: Aleyrodidae)] e lagarta-rosada [Pectinophora gossypiella Saunders, 1844 (Lepidoptera: Gelechiidae)], que podem continuar o seu desenvolvimento nas soqueiras (Torres, 2008;Izeppi et al, 2011;Bianchini & Borges, 2013;. Essa prática é geralmente realizada de maneira mecânica, pela trituração dos tecidos vegetais, mas os recentes avanços nas práticas agrícolas de conservação de solos requerem métodos alternativos, como por exemplo, a aplicação de herbicidas (Yang et al, 2006).…”

“…No Brasil, embora a prática de destruição dos restos de cultura do algodoeiro ao final da safra seja obrigatória por lei, na maioria dos estados produtores (Almeida et al, 2008), poucos são os conhecimentos sobre essa prática de cultivo originados de pesquisa (Bianchini & Borges, 2013). A maioria dos estudos trata dos efeitos desses métodos de destruição sobre os resíduos vegetais do algodoeiro (Silva et al, 1999;Showler et al, 2006a;Yang et al, 2006;Bianchini & Borges, 2013), mas os fatores específicos relacionados à mortalidade do bicudo, após a colheita, não foram avaliados.…”

“…Although the root cutting associated to mechanical destruction of cotton stalk is probably one of the most effective alternatives, no-tillage growers are reluctant to use heavy cultivation to manage stalk cotton due to soil disturbance. Mechanical control limitations are also related to their low operational efficiency and to the difficulty in conducting this operation in rainy periods (Bianchini and Borges, 2013).…”
