AgriBrasilis – O senhor afirmou que a deriva da pulveriza\u00e7\u00e3o via drone \u00e9 menor que a realizada por avi\u00f5es, mas o dobro da realizada por equipamentos terrestres. Dessa forma, o uso de drones n\u00e3o estaria na contram\u00e3o da tecnologia de aplica\u00e7\u00e3o? Essas taxas tendem a diminuir com o avan\u00e7o da tecnologia?<\/strong><\/p>\n

Ulisses Antuniassi – <\/strong>Essa \u00e9 uma quest\u00e3o que se origina de um dado de apenas uma pesquisa, e que n\u00e3o deve ser extrapolada para todas as situa\u00e7\u00f5es.<\/p>\n

Esse dado de propor\u00e7\u00e3o de deriva foi utilizado como contraponto \u00e0 faixa de seguran\u00e7a imposta pela Portaria n\u00ba 298 do MAPA para o uso de drones de pulveriza\u00e7\u00e3o, que prev\u00ea dist\u00e2ncia m\u00ednima de 20 m para alvos sens\u00edveis. O que fizemos foi destacar a deriva coletada em aplica\u00e7\u00f5es com as tr\u00eas modalidades (terrestre, a\u00e9reo convencional e drone) exatamente a 20 m, para comparar as realidades de cada modalidade. Isso n\u00e3o deve ser extrapolado para todas as dist\u00e2ncias e cen\u00e1rios de aplica\u00e7\u00e3o.<\/p>\n

N\u00e3o concordo que drone seja um retrocesso. Drone \u00e9 uma plataforma a\u00e9rea (aplica a 3 m de altura), e portanto n\u00e3o \u00e9 como uma plataforma terrestre de barras, que aplica a 0,5 m de altura. Portanto, drones t\u00eam que ser comparados aos avi\u00f5es convencionais. Nesse contexto, os drones s\u00e3o uma grande evolu\u00e7\u00e3o em termos de seguran\u00e7a, pois simplesmente apresentam muito menos deriva que os avi\u00f5es convencionais.<\/p>\n

Entendo que os drones precisariam de faixas de seguran\u00e7a maiores do que 20 m para produtos de maior impacto em termos de deriva. Essa dist\u00e2ncia tem que ser estudada caso a caso e colocada nas bulas de cada produto.<\/p>\n

AgriBrasilis – Quais os principais cuidados para evitar a deriva durante as pulveriza\u00e7\u00f5es agr\u00edcolas?<\/strong><\/p>\n

Ulisses Antuniassi – <\/strong>Para evitar a deriva devemos seguir os conceitos de boas pr\u00e1ticas. Essa resposta seria muito longa, mas posso sintetizar da seguinte maneira:<\/p>\n
