Resumo: | To test new technology in controlling apple scab caused by Venturia inaequalis (Cooke) Winter, and to reduce the number of treatments, an experiment was carried out at the research station of Caçador, SC, Brazil in the growing season of 1982/83. Four-year old plants of the varieties Fuji and Gala were used. Fungicides were applied on randomized blocks using six replicates with two plants of Fuji and one of Gala each unit for the following treatments: 1. treatment based on Mill’s system; 2. conventional treatment with sprays every 6 to 10 days; 3. control unit with pest management only. Seventy infection periods with 15 low, 8 medium, and 47 heavy infections were registered. To control apple scab 18 fungicide sprays were necessary using the conventional disease management and 17 using Mill's system. The ascospore flight of Venturia inaequalis began the end of September ceasing the end of November 1982. Considerable differences between the treated and untreated blocks of Fuji and Gala could be observed, concerning the attack of apple scab (Venturia inaequalis), bitter rot (GIomerella cingulata), apple blotch disease (Gloeodes pomigena) and fly speck (Leptothyrium pomi), total weight/plant, weight/fruit, fruit size and yield per hectare. |

Foram aplicados fungicidas com os seguintes tratamentos, em blocos casualizados, com seis repetições e duas plantas de ‘Fuji’ e uma de 'Gala' por parcela: 1. tratamento conforme a tabela de Mills; 2. tratamento convencional cada sete a dez dias; 3. testemunha só controlando as pragas. Foram observados 70 períodos de infecção: 15 períodos de infecção leve, 8 de média e 47 de infecção grave. Foram realizadas 18 aplicações para controlar as doenças pelo sistema convencional, contra 17 pelo uso da tabela de Mills. A flutuação de ascósporos de Venturia inaequalis durou dois meses (fins de setembro a fins de novembro), houve grandes diferenças entre a testemunha e os dois tratamentos e entre as duas cultivares Fuji e Gala com relação ao ataque da sarna (Venturia inaequalis), podridão-amarga (Glomerella cingulata), fuligem dos frutos (Gloeodes pomigena), sujeira de mosca (Leptothyrium pomi), peso de frutos por planta, peso médio dos frutos, tamanho dos frutos e rendimento por hectare.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBerton, OnofreMelzer, Reinhard2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16114Pesquisa Agropecuaria Brasileira; v.19, n.10, out. 1984; 1211-1217Pesquisa Agropecuária Brasileira; v.19, n.10, out. 1984; 1211-12171678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16114/10270info:eu-repo/semantics/openAccess2014-04-16T19:09:29Zoai:ojs.seer.sct.embrapa.br:article/16114Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:09:29Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
