“…Studies verifying compatibility between molecules are essential to assess the feasibility of those pesticide mixture with the same quality as the isolated use. Studies evaluating the compatibility of synthetic chemical insecticides and herbicides were carried out, which verified that most of the molecules are compatible, demonstrating the efficiency of the mixture of substances in pest control (GANDINI et al, 2020;MA et al, 2016;PETTER et al, 2012); however, as far as we know this is the first research evaluating the mixture compatibility of chemical pesticides with AgMNPV.…”

“…Mixing different pesticides (insecticides with herbicides or fungicides) was started as an alternative to reduce the costs of the increased need to control both insects and weeds or plant pathogens ate the same time (GANDINI et al, 2020;ZANDONADI et al, 2018). However, the mixture of different molecules can reduce control of these substances.…”

“…This study will allow knowing which herbicide or fungicide can be mixed with AgMNPV in the same spray's operation. The use of combined pesticides in a single spray is a desired practice in the management of soybean fields due to less soil compaction, decreased machinery's cost, and increased safety to growers due to reduced time spent spraying pesticides in the field (GANDINI et al, 2020;HENRY et al, 2011;PETTER et al, 2012). Not only is it important to evaluate the efficacy of pesticides immediately after the mixture but also at different time after products mixture since in field conditions, it might take hours for growers to spray the whole crop after preparing the sprayer with pesticides.…”

Mixture compatibility of Anticarsia gemmatalis nucleopolyhedrovirus (AgMNPV) with pesticides used in soybean

et al. 2022

Anticarsia gemmatalis (Hübner: 1818) (Lepidoptera: Erebidae) is one of the main pests that affect soybean crops, causing defoliation. In the vegetative stages, defoliation occurs together with weeds, and in the reproductive stages with pathogens. In this sense, to maintain plant health, it is necessary to carry out the combined use of pesticides. Thus, this research determined the compatibility of the entomopathogenic virus AgMNPV with the main herbicides and fungicides used in soy at different times of the mixture. The artificial diet was immersed in the solutions of the pesticides and their mixtures and supplied to A. gemmatalis caterpillars, immediately and after one and two hours of mixing. The evaluation was performed by quantifying the number of dead caterpillars by mixing the AgMNPV virus with herbicides and fungicides, even after two hours of mixing if compatible. The observed scenarios showed a compatibility of the virus with the herbicides and fungicides, with mortality rates between 70 to 99% for A. gemmatalis.

“…Of all the respondents, 33% said they were using mineral fertiliser, but when we probed further, we found that the amounts of nutrients added were almost insignificant (less than one kg per hectare). Many of our respondents reported that they mixed fertilisers with insecticides or fungicides, which may compromise the effectiveness of the plant protection agents (Gandini et al 2020;Griffith 2010). Finally, farmers who claimed to fear dependency on fertilisers indicated that once fertilisers were used, the yield could not be sustained without them.…”

Farmers’ Perceptions as a Driver of Agricultural Practices: Understanding Soil Fertility Management Practices in Cocoa Agroforestry Systems in Cameroon

et al. 2020

In Africa, cocoa yields are low, partly due to soil fertility constraints and poor management. While peoples’ knowledge, aspirations, and abilities are key factors explaining their behaviour, little is known about the rationales that underpin soil fertility management practices (SFMPs) of cocoa farmers. To address this gap, we conducted an exploratory survey in two contrasting regions in Cameroon where cocoa is an important crop: the humid forest and the forest-savannah transition zone. Some 30% of farmers in the transition zone as opposed to 13% in the humid forest expressed concerns about soil fertility. The most relevant soil fertility indicators for farmers were high cocoa yield, dark soil colour, ease of tillage, and floral composition. To enhance and maintain soil fertility, farmers used residues from weeding (100%), planting of trees (42%), mineral fertilisers (33%), compost (16%), and manure (13%). More farmers in the transition zone than the humid forest implemented SFMPs. Our findings suggest that soil fertility perceptions, access to inputs, local practices, and experience influence farmers’ use of SFMPs. The limited use of mineral fertilisers was explained by poor access whereas the use of organic fertilisers and tree planting were mostly constrained by lack of labour and knowledge. Farmers prioritised practices to increase yield and viewed SFMPs to be the least important management practices, although they believe high cocoa yield is an important indicator of soil fertility. To foster sustainable cocoa intensification, it is necessary to enhance farmers’ knowledge on SFMPs, increase access to inputs, and ensure returns on investment while considering farmers’ priorities and practices.

“…The approval of new pesticides by MAPA requires knowledge of their isolated effects and possible interactions in tank mixtures. Pesticide mixtures have been used to pest control simultaneously and reduce management costs [6,7]. Legalizing this practice occurred with the Normative Instruction No.…”

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.
