“…Considering that 2,4-D and triclopyr herbicides do not have control over ryegrass, since plants of this family have a tolerance to them, the expected control of the mixture is the same as the observed control of the graminicide in a sole application (GUERRA et al, 2013). The COLBY's mathematical model does not conside the statistical comparison, but considers an antagonistic effect when the observed value (control) is lower than expected; thus, the values were compared using the t-test (MATZENBACHER et al, 2015;TREZZI et al, 2016;DIESEL et al, 2018).…”

This study aimed to evaluate the antagonistic effect of the mixture ofacetyl coenzyme-A carboxylase (ACCase) enzyme inhibiting herbicides and auxin herbicides in Lolium multiflorum and to determine mechanisms to mitigate this possible effect. The first experiments were conducted by associating the herbicide clethodim (108 g a.i. ha−1), quizalofop-p-ethyl (54 g a.i. ha−1), and clethodim + quizalofop-p-ethyl (108+54 g a.i. ha−1) with 2,4-D (1005 g a.e. ha−1) or triclopyr (720 g a.e. ha−1), in addition to the sole application of the respective graminicides. Another experiment included clethodim (54; 81; 108; 162; 216 g a.i. ha−1), quizalofop-p-ethyl (27; 40.5; 54; 81; 108 g a.i. ha−1), and clethodim + quizalofop-p-ethyl (54+27; 81+40.5; 108+54; 162+81; 216+108 g a.i. ha−1) mixed with 2,4-D (1005 g a.e. ha−1), or triclopyr (720 g a.e. ha−1), in addition to the control treatments without herbicide application. In the second experiment, herbicides clethodim (108 g a.i. ha−1), quizalofop-p-ethyl (54 g a.i. ha−1), and clethodim + quizalofop-p-ethyl (108+54 g a.i. ha−1) in combination with the herbicides 2,4-D (1005 g a.e. ha−1) or triclopyr (720 g a.e. ha−1)had malathion (1000 g a.i. ha−1) or glyphosate (720 g a.e. ha−1) mixed, in addition to the sole applications of the graminicides. The herbicide clethodim + quizalofop-p-ethyl did not present an antagonistic interaction with the auxin herbicides, and obtained 85% weed control. To obtain control similar to the sole application of this graminicide, the dose of the herbicide clethodim needs to be increased by 20%. However, the mixture of the herbicide quizalofop-p-ethyl with 2,4-D and triclopyr affects the ryegrass control. The use of strategies that increase the absorption of ACCase herbicides or the inhibition of P450 enzymes are ways to mitigate the antagonistic effect caused by the association of the two auxin herbicides.

“…However, although a combination of herbicides having different modes of action seems to favor the occurrence of a synergistic interaction, some studies have contrasting results. For example, antagonistic interaction has been noticed by Diesel et al (2018) when trying to control Euphorbia heterophylla using a mixture of saflufenacil and clomazone, metribuzin, or paraquat …”

The use of herbicide combinations is a common practice in modern agriculture. However, unexpected results may be observed due to herbicide and weed diversity, therefore, highlighting the need for a predictive strategy. To this end, a data set was made based on recent studies. This data set included herbicide attributes, such as active ingredient, chemical family, and mode of action, and weed attributes, namely, species, clade, type of leaves, family, and lifespan. Globally, additive interactions (46.30%) were more frequent than antagonistic (29.09%) and synergistic (24.61%) ones. The occurrence of these herbicide interactions with regard to herbicide and weed features is also discussed. Moreover, mesotrione and glyphosate have been, respectively, identified as the most promising or inadequate herbicides in predicting beneficial mixtures. The resulting global trend could guide farmers in their choice of beneficial herbicide companions.

Expansion of Planted Forests: The Risk of Pesticides Mixtures

Planted forests include forests established through human planting or deliberate seeding. They are systems that offer us timber and non-timber forest products and ecosystem services, such as wildlife protection, carbon sequestration, soil, and watershed maintenance. Brazil has 7.6 million hectares of planted forests, with 72% of the total area occupied by Eucalyptus spp. A favorable climate and management and genetic improvement research are the main factors responsible for high productivity. In recent years, the expansion of planted areas has been accompanied by the commercial release of several pesticides, mainly herbicides. A recent change in the Brazilian legislation allows mixing phytosanitary products in a spray tank, having a new approach to managing pests, diseases, and weeds. Antagonism is the main risk of tank mixes, and to reduce the dangers associated with this practice, we review all products registered for growing Eucalyptus. This literature review aims to identify the effects of product mixtures registered for Eucalyptus reported for other crops. In addition, environmental and social risk assessment has been widely adopted to export wood and cellulose, making the results of this review an indispensable tool in identifying the nature and degree of risks associated with pesticides. The results classify the effects of the mixtures as an additive, antagonistic or synergistic. The use of pesticide tank mixtures has the potential for expansion. However, there are still challenges regarding variations in the effects and applications in different climatic conditions. Therefore, studies that prove efficient mixtures for the forest sector are essential and the training of human resources.
