Herbicide combinations for the control of weeds in cotton

Herbicide combinations for the control of weeds in cotton

In order to determine the effect of several herbicide combinations against weeds in cotton (Gossypium hirsutum var. latifolium L.) fields a trial was placed at Surubim, PE, Brazil, in 1978. None of the treatments caused deleterious effects to cotton plant. The residual herbicides were slightly more efficient controlling weeds when applied in pre-emergence state as compared to pre-sowing incorporation. The more efficient mixtures, which allowed higher cotton fields, were: alachlor 3,0 l/ha (pre-emergent) + diuron 1,0 kg/ha (pre-emergent); penoxalin 3,0 l/ha (pre-emergent) + diuron 1,0 kg/ha (pre-emergent) and trifluralin 1,5 l/ha (pre-sowing incorporated) + fluometuron 1,5 kg/ha (pre-emergent). The predominant weeds were: Malvastrum coromandelianum (L.) Gurcke, Ageratum conyzoides L., Boerhavia decumbens L., Alternathera ficoidea L, Galinsoga parviflora Cav., Ipomoea sp., Achanthorpermum hispidum DC., Hyptis capitata Jacq., Desmodium tortuosum (Swartz) DC., Cenchrus echinatus L., Paspalum sp., Cyperus sp.

Um ensaio foi conduzido no município de Surubim, PE, no ano de 1978, com o objetivo de determinar o efeito de várias combinações de herbicidas sobre o algodoeiro (Gossypium hirsutum var. latifolium L.) e o controle das ervas daninhas incidentes nesta cultura. Nenhum dos tratamentos causou efeito adverso à planta do algodoeiro. Os herbicidas residuais, quando aplicados em pré-emergência, mostraram-se ligeiramente mais eficientes no controle das invasoras que quando aplicados em pré-plantio incorporado. As misturas mais eficazes no controle das invasoras e que permitiram os mais elevados rendimentos do algodoeiro, foram: alachlor 3,0 l/ha (pré) + diuron 1,0 kg/ha (pré), penoxalin 3,0 l/ha (pré) + diuron 1,0 kg/ha (pré) e trifluralin 1,5 l/ha (ppi) + fluometuron 1,5 kg/ha (pré). As ervas daninhas predominantes foram: Malvastrum coromandelianum (L.) Gurcke, Ageratum conyzoides L., Boerhavia decumbens L., Alternathera ficoidea L., Galinsoga parviflora Cav., Ipomoea sp., Acanthospermum hispidum DC., Hyptis capitata Jacq., Desmodium tortuosum (Swartz) DC., Cenchrus echinatus L., Paspalum sp., Cyperus sp.   Pesquisa Agropecuaria Brasileira Pesquisa Agropecuária Brasileira 2014-04-15 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf https://seer.sct.embrapa.br/index.php/pab/article/view/16362 Pesquisa Agropecuaria Brasileira; v.17, n.11, nov. 1982; 1577-1583 Pesquisa Agropecuária Brasileira; v.17, n.11, nov. 1982; 1577-1583 1678-3921 0100-104x por https://seer.sct.embrapa.br/index.php/pab/article/view/16362/10588
