ABSTRACT - Herbicide drift, due to application failures, can cause intoxication in
eucalyptus plants, compromising their growth. However, the addition of protective
products such as Fertiactyl P&#xF3;s&#xAE; to the syrup has been shown to be efficient in
reducing intoxication of eucalyptus plants exposed to herbicide drift. Given this, the
objective of the present study was to evaluate the protective effect of Fertiactyl
P&#xF3;s&#xAE; on the reduction of damage caused by the herbicides glyphosate, 2,4-D and the
glyphosate + 2.4-D mixture in eucalyptus plants. The experiment was conducted in a
3 x 2 + 1 factorial scheme, corresponding to three herbicides: glyphosate (1,440 g ha-1),
2,4-D (680 g ha-1), glyphosate + 2.4- D (1,440 g ha-1 + 680 g ha-1); two doses of
Fertiactyl P&#xF3;s&#xAE; (0 and 3.0 L ha-1) and one control without application. Prior to
application, the top of the eucalyptus was covered with polyethylene bags to ensure
the syrup only reached the lower third of the canopy. The addition of Fertiactyl P&#xF3;s&#xAE;
to the syrup with glyphosate and 2.4 D herbicides reduced the intoxication of
eucalyptus plants by 21.9 and 15.2%, respectively, at 40 days after application (DAA)
when compared with the application of the respective herbicides without the addition
of Fertiactyl P&#xF3;s&#xAE;. The glyphosate + 2.4-D mixture drift intensified the intoxication of
the eucalyptus plants in comparison with the application of the respective herbicides
in isolation. Besides, the addition of Fertiactyl P&#xF3;s&#xAE; to the glyphosate + 2,4-D mixture
did not prevent plant intoxication.

Keywords: glyphosate, 2.4-D, plant detoxification, herbicide mixture.

RESUMO - A deriva de herbicida, por falhas de aplica&#xE7;&#xE3;o, pode causar intoxica&#xE7;&#xE3;o
em plantas de eucalipto, comprometendo o crescimento destas. Entretanto, a adi&#xE7;&#xE3;o
de produtos protetores como Fertiactyl P&#xF3;s&#xAE; &#xE0; calda tem se mostrado eficiente na
redu&#xE7;&#xE3;o da intoxica&#xE7;&#xE3;o de plantas de eucalipto expostas &#xE0; deriva de herbicidas.
Em face do exposto, objetivou-se neste trabalho avaliar o efeito protetor do
Fertiactyl P&#xF3;s&#xAE; sobre a redu&#xE7;&#xE3;o de danos causados pela deriva dos herbicidas
glyphosate, 2,4-D e a mistura glyphosate + 2,4-D em plantas de eucalipto. O
experimento foi conduzido em esquema fatorial 3 x 2 + 1, correspondendo a tr&#xEA;s
herbicidas: glyphosate (1.440 g ha-1), 2,4-D (680 g ha-1) e mistura em tanque de
glyphosate + 2,4-D (1.440 g ha-1 + 680 g ha-1); duas doses de Fertiactyl P&#xF3;s&#xAE;
(0 e 3,0 L ha-1); e uma testemunha sem aplica&#xE7;&#xE3;o. Antes da aplica&#xE7;&#xE3;o, a parte
superior da copa do eucalipto foi protegida com sacos de polietileno, de modo a
permitir que a calda atingisse apenas o ter&#xE7;o inferior do dossel. A adi&#xE7;&#xE3;o do
Fertiactyl P&#xF3;s&#xAE; &#xE0; calda com os herbicidas glyphosate e 2,4-D reduziu a intoxica&#xE7;&#xE3;o
das plantas de eucalipto em 21,9% e 15,2%, respectivamente, aos 40 dias ap&#xF3;s a
aplica&#xE7;&#xE3;o (DAA), em rela&#xE7;&#xE3;o &#xE0; aplica&#xE7;&#xE3;o dos respectivos herbicidas sem adi&#xE7;&#xE3;o
de Fertiactyl P&#xF3;s&#xAE;. A deriva da mistura glyphosate + 2,4-D potencializou a
intoxica&#xE7;&#xE3;o das plantas do eucalipto em rela&#xE7;&#xE3;o &#xE0; aplica&#xE7;&#xE3;o isolada dos respectivos herbicidas e n&#xE3;o
houve resposta da adi&#xE7;&#xE3;o do Fertiactyl P&#xF3;s&#xAE; na redu&#xE7;&#xE3;o da intoxica&#xE7;&#xE3;o das plantas quando se aplicaram
os herbicidas em mistura.

Palavras-chave: glyphosate, 2,4-D, desintoxica&#xE7;&#xE3;o de plantas, mistura de herbicidas.</subfield>
