It is necessary to identify new herbicides with a wide spectrum of weed control for bean crops, and have an adequate security margin for this crop. The main objectives of this work were to evaluate the potential use of ethoxysulfuron herbicide on controlling weeds and three soybean cultivars between bean crop, as the tolerance of IAC Imperador bean cultivar to this herbicide. An experiment was conducted on field with a split-plot design. At the whole plot were allocated the doses […]

Black bean is one of the main grains grown in Brazil, with economic, social and cultural importance. Grain productivity losses due to competition with weeds, in particular Digitaria ciliaris (summergrass) and Urochloa plantaginea (signalgrass) can reach levels of up to 80% if neither Control is adopted. The objective of this study was to evaluate the efficacy and selectivity of herbicides applied in pre and post emergence of black beans. The experimental design was a randomized block design, with four replications. […]

The productive increase of the maize crop can be maximized by crop densification and, for this, the use of herbicides and growth regulators, because it favors the reduction of plant size, becomes an important tool. Thus, the objective of this study was to evaluate the rates of growth reducers on the phytometric performance of maize simple hybrids. The design was completely randomized, in a 2 x 5 factorial scheme, with four replications. Growth factors (trinexapac-ethyl and clomazone) were considered as […]

The main weeds in wheat are wild radish and ryegrass, and its post-emergence control is based on herbicides inhibiting the enzyme acetolactate synthase (ALS) and acetyl coenzyme A carboxase (ACCase), which as a function of resistance limits the control options. Herbicide combinations have been used for post-emergence of wheat; however, the effects of herbicidal combinations are poorly understood. The objective of this work was to evaluate the selectivity of wheat to herbicide associations and rates applied in post-emergence. Three field […]

The solar radiation reduction incident on the terrestrial surface can changes the vegetal behavior and the herbicide selectivity. The aim of this work was to evaluate the herbicide selectivity bentazon, iodosulfuron-methyl-sodium and grain yield of wheat under conditions of reduction of luminosity in different phenological stages of the crop. Two experiments were conducted, the first (I) under controlled conditions and the second (II) in field. In both experiments, wheat was evaluated according to the herbicide application (bentazone, 900 g ha-1 […]

Alternative to decontaminate the soil is the phytoremediation practice. In this way, this study aimed to evaluate the phytoremediation potential of the following species: vetch, radish, cereal rye, black soybean and colonião grass, grown in a soil contaminated with atrazine and chlorimuron ethyl + sulfometuron-methyl. The herbicides were applied in pre-emergence of the species. Two experiments were installed, the first one tested the phytoremediation potential of the species and the second one used the cucumber as bioindicator culture to prove […]

Weed control is one of the capital requirements to provide suitable growth and establishment of banana orchards. However, very few options of herbicides are available for this crop. From this context, the objective of this work is to evaluate weed control and selectivity of the new herbicide indaziflam apllied pre-emergence in a directed spray to the inter rows area of banana orchards, targeting the weeds hairy flebane (Conyza bonariensis), Jamaican crabgrass (Digitaria horizontalis) and spiny sandbur (Cenchrus echinatus). A field […]
