Portuguese term or phrase: testemunha sem controle
Na análise conjunta dos 23 ensaios, todos os tratamentos apresentaram
severidade estatisticamente inferior à testemunha sem controle (Tabela x).
Os tratamentos que apresentaram a menor severidade foram azoxistrobina +
ciproconazol (T2) e picoxistrobina + ciproconazol (T16). As maiores severidades
foram observadas para os tratamentos com epoxiconazol (T4) e flutriafol (T5).
A eficiência de controle para os melhores tratamentos foi de 73% (T2) e 69%
(T16). A severidade apresentou alta correlação com a produtividade (r=-0,98)
na análise utilizando os 23 locais. De maneira geral, as misturas de triazóis e
estrobilurinas (T2, T7, T14, T15 e T16), apresentaram uma maior eficiência
de controle quando comparadas com os triazóis sozinhos ou em mistura com
benzimidazóis, sendo observado o controle com as misturas variando de 63%
a 73%, e com os triazóis variando de 34% a 49%, e os grupos individualizados
estatisticamente pelo teste de Tukey.

Artificial infestations increased the damage 32 fold, in relation to natural infestations in the untreated control. Insecticides reduced larval survival significantly for 60 days after planting compared to the untreated control.(AU)

Infestações artificiais usadas neste estudo aumentaram o dano em 32 vezes, em relação à infestação natural das testemunhas. Inseticidas reduziram significativamente a sobrevivência de larvas até 60 dias após o plantio, comparados com a testemunha.(AU)
