Resumo 

Objetivando avaliar a eficiência e a seletividade do herbicida tembotrione, isolado e complementado com atrazina no controle de plantas daninhas na cultura do milho, instalou-se um experimento  na  Fazenda  Escola  da  Universidade  Estadual  de  Ponta  Grossa,  no  ano  agrícola 2004/05.  O  delineamento  experimental  foi  de  blocos ao  acaso  com  nove  tratamentos  e  quatro repetições.  Os  tratamentos  constaram  da  aplicação  em  pós-emergência  de  0,12  L  ha-1 de  Equip Plus  (foransulfuron  &amp;  iodosulfuron  methyl  sodium)  complementado  com  2  L  ha-1 de  Atrazinax (atrazina)  e  de  1,0  L  ha-1  de  Hoefix  (espalhante  adesivo);  0,60  L  ha-1 de  Sanson  (nicosulfuron) complementado com 2,0 L ha-1 de Atrazinax; 0,30 L ha-1 de Callisto (mesotrione) complementado com  3,0  L  ha-1  de  Primóleo  (atrazina);  Soberan  (tembotrione)  nas doses  de  0,18  e  0,24  L  ha-1complementado com 2  L ha-1 de Atrazinax e adicionados de 1,0  L ha-1 de Aureo (óleo metilado de soja) e nas doses de 0,24 e 0,30 L ha-1 adicionado de 1,0 L ha-1 de Aureo; testemunha capinada e  testemunha  sem  capina.  O  híbrido  utilizado  foi  DKB-215.  O  Soberan  complementado  com atrazina  é  eficiente  no  controle  para Brachiaria  plantaginea,  Digitaria  horizontalis  e Bidens pilosa,  com  resultados  similares  a  Callisto  +  Atrazinax  e  iguais  ou  superiores  a  Equip  Plus  e  a Sanson  +  Atrazinax.  Quando  aplicado  isolado,  o  Soberan  mostrou  igual  resultado  para  as gramíneas, porém, para Bidens pilosa o controle foi eficiente, mas inferior a alguns tratamentos; o Soberan isolado, ou em mistura com Atrazinax, causou leves sintomas de fitotoxicidade até 14 dias após sua aplicação, tal qual a mistura de Equip Plus e de Sanson + Atrazinax.

Abstract  

With  the  aim  of  evaluate  the  efficiency  and  the  selectivity  of  the  tembotrione herbicide, isolated and complemented with atrazine, in the weeds control of the corn culture, an experiment  was  installed  at  the  UEPG  School  Farm,  in  the  2004/05  agricultural  year.  The experimental design was a complete randomized blocks with nine treatments and four repetitions. The  treatments  consisted  of  the  postemergence  application  of  Equip  Plus  (foransulfuron  &amp; iodosulfuron methyl sodium) - 0,12 L ha-1 complemented with Atrazinax (atrazine) - 2 L ha-1 and Hoefix (adjuvant) - 1,0 L ha-1; Sanson (nicosulfuron) - 0,60 L ha-1 complemented with Atrazinax - 2,0 L ha-1; Callisto (mesotrione) - 0,30 L ha-1 complemented with Primóleo (atrazine) - 3,0 L ha-1;  Soberan  (tembotrione)  -  0,18  and  0,24  L  ha-1  complemented  with  Atrazinax  -  2  L  ha-1  and added  of  Aureo  (metilado  oil  of  soy)  -  1,0  L  ha-1;  Soberan  (tembotrione)  -  0,24  and  0,30  L  ha-1 added of Aureo (metilado oil of soy) - 1,0 L ha-1; with and without weeding. The used hybrid was DKB-215.  Soberan  complemented  with  Atrazinax  is  efficient  in  the  control  for Brachiaria plantaginea,  Digitaria  horizontalis  e Bidens  pilosa  ,  with  similar  results  to  Callisto  +  Atrazinax and  equal  or  superior  results  to  Equip  Plus  and  Sanson  +  Atrazinax.  When  applied  isolated Soberan  it  showed  equal  result  for  the  grassy  ones,  however,  for Bidens  pilosa  the  control  was efficient,  but  inferior  to  some  treatments;  Soberan  in  the  biggest  rate  and  with  Atrazinax  after promoted light symptoms of fitotoxicity up to 14 days its application, such which the mixture of Equip Plus and Sanson + Atrazinax.
