Early assessment of tree species with potential for carbon offset plantations i...

Morais Junior, Vicente Toledo Machado de; Jacovine, Laércio Antônio Gonçalves; Torres, Carlos Moreira Miquelino Eleto

A database on the performance of native plants under different environmental conditions can improve the selection of species most suitable for carbon offset programs. The objective of this work was to identify the potential of 25 tree species for carbon offsetting in a degraded area in the Brazilian Atlantic Forest, with a scoring system based on the survival rate (SV) and average annual carbon increment (IMAC)...

Identifying Chloris species from Cuban citrus orchards and determining their Gl...

Bracamonte, Enzo R.; Fernández-Moreno, Pablo T.; Bastida, Fernando; Osuna, María D.; Cruz, Ricardo Alcántara-de la; Cruz-Hipolito, Hugo E.

The Chloris genus is a C4 photosynthetic species mainly distributed in tropical and subtropical regions. Populations of three Chloris species occurring in citrus orchards from central Cuba, under long history glyphosate-based weed management, were studied for glyphosate-resistant status by characterizing their herbicide resistance/tolerance mechanisms. Morphological and molecular analyses allowed these species ...

First confirmation and characterization of target and non-target site resistanc...

Dominguez-Valenzuela, Jose Alfredo; Gherekhloo, Javid; Fernández-Moreno, Pablo Tomás; Cruz-Hipolito, Hugo Enrique; Cruz, Ricardo Alcántara-de la

Following the introduction of glyphosate-resistant (GR)-cotton crops in Mexico, farmers have relied upon glyphosate as being the only herbicide for in-season weed control. Continuous use of glyphosate within the same year and over multiple successive years has resulted in the selection of glyphosate resistance in Palmer amaranth (Amarantus palmeri). Dose-response assays confirmed resistance in seven different a...

Glyphosate-based herbicides toxicity on life history parameters of zoophytophag...

Serrão, José E.; Zanuncio, José C.; Lacerda, Mabio C.; Cruz, Ricardo Alcántara-de la; Brügger, Bruno P.; Pereira, Alexandre I.A.; Wilcken, Carlos F.

The increase of agricultural areas with glyphosate-resistant (GR) crops, and use of this herbicide in Brazil, makes necessary to assess its impacts on non-target organisms. The objective was to evaluate the development, reproduction and life table parameters of Podisus nigrispinus (Heteroptera: Pentatomidae) reared on GR-soybean plants treated with glyphosate formulations (Zapp-Qi, Roundup-Transorb-R and Roundu...

Pro-106-Ser mutation and EPSPS overexpression acting together simultaneously in...

Gherekhloo, Javid; Fernández-Moreno, Pablo T.; Cruz, Ricardo Alcántara-de la; Sánchez-González, Eduardo; Cruz-Hipolito, Hugo E.

Glyphosate has been used for more than 15 years for weed management in citrus groves in the Gulf of Mexico, at up to 3–4 applications per year. Goosegrass (Eleusine indica (L.) Gaertn.) control has sometimes failed. In this research, the mechanisms governing three goosegrass biotypes (Ein-Or from an orange grove, and Ein-Pl1 and Ein-Pl2 from Persian lime groves) with suspected resistance to glyphosate were char...

Differential resistance mechanisms to Glyphosate result in fitness cost for Lol...

Fernández-Moreno, Pablo T.; Cruz, Ricardo Alcántara-de la; Smeda, Reid J.; Prado, Rafael De

Multiple mechanisms of resistance to glyphosate are exhibited by populations of Lolium spp. worldwide. Association of resistance with growth and reproductive fitness is an important predictor for long-term success of glyphosate-resistant (R) versus glyphosate-susceptible (S) biotypes. Numerous studies were conducted on R- and S-biotypes of Italian ryegrass (Lolium multiflorum) and perennial ryegrass (L. perenne...

Effectiveness of alternative herbicides on three Conyza species from Europe wit...

Silveira, Hellen Martins da; Tahmasebi, Behroz Khalil; Alebrahim, Mohammad Taghi; Roldán-Gómez, Rafael A.; Silveira, Hellen Martins da

Glyphosate has been applied in European countries for over a decade between rows in olive groves and grape vineyards to control Conyza species [hairy fleabane (C. bonariensis), horseweed (C. canadensis) and Sumatran fleabane (C. sumatrensis)], however poor control has been observed in recent years. Glyphosate susceptible (GS) or resistant (GR) populations were assayed in each species. In addition, Conyza spp. c...

Quantifying the harmful potential of ten essential oils on immature Trichogramm...

Parreira, Douglas Silva; Cruz, Ricardo Alcántara-de la; Leite, Germano Leão Demolin; Ramalho, Francisco de Souza; Zanuncio, José Cola

The use of chemical insecticides and non-selective natural products authorized for use in organic farming may reduce the effectiveness of egg parasitoids. The side-effects of ten plant essential oils on immature stages of Trichogramma pretiosum were evaluated. Carapa guianensis, Origanum vulgare and Zingiber officinalle during the F1 generation, and Azadirachtin and Mentha piperita in the F2 generation were sli...

Parreira, Douglas Silva; Cruz, Ricardo Alcántara-de la; Zanuncio, José Cola; Lemes, Pedro Guilherme; Rolim, Gabriela da Silva

Essential oils from botanical extracts used for insect pest control should be both effective and have low impact on natural enemies. The objective was to evaluate the effects of ten essential oils on the biological and reproductive parameters in two Trichogramma galloi Zucchi (Hymenoptera: Trichogrammatidae) generations. The emergence F1 generation of T. galloi was reduced by more than 30% with Allium sativum, ...

Geotechnology in the analysis of forest fragments in northern Mato Grosso, Brazil

Barbosa, Sergio Guedes; Spletozer, Aline Gonçalves; Roque, Mariane Paulina Batalha; Ferreira Neto, José Ambrosio; Dias, Herly Carlos Teixeira

O artigo não contem resumo em português; Pasture implantation fragments and reduces the Amazonian forest area. The objective was to quantify landscape changes in 1985, 2000 and 2015 in northern Mato Grosso, Brazil. The study was carried out in three scenes obtained by the LANDSAT satellite of a microbasin (2742.33 ha) in the municipality of Alta Floresta. Forest, water bodies, pasture and exposed soil were the ...
