摘要

摘要:由于施用失败,除草剂漂移会导致桉树中毒,影响其生长。然而,在糖浆中添加防护产品,如Fertiactyl Pós®,已被证明可以有效地减少桉树植物暴露于除草剂漂移的中毒。鉴于此,本研究的目的是评价Fertiactyl Pós®对减少草甘膦、2,4- d和草甘膦+ 2.4-D混合除草剂对桉树的伤害的保护作用。试验采用3 × 2 + 1因子方案,对应3种除草剂:草甘膦(1440 g ha-1)、2,4-D (680 g ha-1)、草甘膦+ 2.4- D (1440 g ha-1 + 680 g ha-1);两剂Fertiactyl Pós®(0和3.0 L ha-1)和一组未应用的对照。在施用之前,桉树的顶部用聚乙烯袋覆盖,以确保糖浆只到达树冠的下三分之一。与不添加Fertiactyl Pós®的除草剂相比,在草甘膦和2.4 D除草剂的糖浆中添加Fertiactyl Pós®,在施用后40天(DAA),桉树植物的中毒程度分别降低了21.9%和15.2%。与单独使用草甘膦+ 2.4-D混合漂移相比,草甘膦+ 2.4-D混合漂移对桉树的毒害作用更强。此外,在草甘膦+ 2,4- d混合物中添加Fertiactyl Pós®并不能防止植物中毒。

Use of Fertiactyl Pos® for Protection of Eucalyptus Plants Subjected to Herbicide Drift
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 Pós® 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 Pós® 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 Pós® (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 Pós® 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 Pós®. 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 Pós® to the glyphosate + 2,4-D mixture did not prevent plant intoxication.
