Resumo
O objetivo do presente trabalho foi avaliar a eficiência de diferentes produtos fitossanitários aplicados via solo e foliar no controle da ferrugem em cafeeiro conilon e avaliar o dano causado pela ferrugem nesse cafeeiro. Um delineamento experimental em blocos ao acaso com quatro repetições foi usado no experimento. As parcelas foram compostas por 10 plantas cada. Os tratamentos fitossanitários foram: 1-Testemunha (sem controle da doença); 2- Ciproconazol+tiametoxam via solo no mês de novembro; 3-Triadimenol+imidaclopride via solo no mês de novembro; 4-Flutriafol+imidaclopride via solo no mês de novembro; 5-Ciproconazol+tiametoxam via solo no mês de novembro e azoxistrobin+ciproconazol via foliar no mês de julho; 6-Tiametoxam+ciproconazol via solo no mês de novembro e azoxistrobin+ciproconazol via foliar no mês de julho; 7-Triadimenol+imidaclopride via solo no mês de novembro e trifloxistrobin+ciproconazol via foliar no mês de julho; 8-Flutriafol+imidaclopride via solo no mês de novembro e flutriafol via foliar no mês de julho. As avaliações foram mensais e os dados gerados foram analisados pelo teste Skott- Knott a 5% de significância, usando o programa SAEG. A avaliação do dano foi realizada pela análise da AACPD e da produção dos tratamentos com e sem alta incidência da ferrugem. Os tratamentos mais eficientes na redução daferrugem, avaliando a AACPD de 2009 e 2010, foram o 2, 4, 5, 6 e 8. Estes mesmo tratamentos também foram os mais produtivos. Na avaliação do dano causado no cafeeiro conilon, plantado no sistema de intercalação do clone 02 com o G35, a ferrugem pode causar um dano de até 47% na lavoura se medidas adequadas de controle da doença não forem implementadas.
The aim of this study was to evaluate the efficacy of different pesticides applied to soil and leaf rust control in the coffee conilon and assess the damage caused by rust this coffee. A randomized complete block design with four replications was used in the experiment. The plots had 10 plants each. The pesticide treatments were: 1- Control (without disease control), 2-cyproconazole + thiamethoxam in the soil in November, 3-Triadimenol + imidacloprid in the soil in November, 4-Flutriafol + imidacloprid in the soil in November , 5-cyproconazole + thiamethoxam in the soil in November and azoxystrobin + cyproconazole foliar in July, 6-Thiamethoxam + cyproconazole via soil in November and azoxystrobin + cyproconazole foliar in July, 7-Triadimenol + imidacloprid in the soil in November and trifloxystrobin + cyproconazole foliar in July, August-Flutriafol + imidacloprid in the soil in November and foliar flutriafol in July. All were evaluated monthly and the resulting data were analyzed by Skott-Knott test at 5% significance, using the program SAEG. The assessment of the damage was done by analysis of AACPD and production of the treatments with and without high incidence of rust. The most effective treatments in reducing rust, evaluating the AACPD in 2009 and 2010, were 2, 4, 5, 6 and 8. These same treatments were also the most productive. In assessing the damage caused in conilon coffee planted in the system merge clone 02 with the G35, the rust can cause damage of up to 47% in the crop if appropriate measures of disease control are not implemented.
