Quinoa (Chenopodium quinoa) reaction to herbicide residue in a Brazilian Savannah soil [PDF]

Pesquisa Agropecuária Brasileira, 2003
The quinoa (Chenopodium quinoa Willd.) cultivation, one of the most promising in double cropping with soybeans or maize, depends on weed control. The objective of this work was to evaluate quinoa reaction to herbicide residue in a savannah soil.

Effects of Antimitotic Agents, Temperature and Immersion Time on Chromosome Doubling Efficiency in Supersweet Corn (Zea mays L. var. saccharata)

Plant Breeding, EarlyView.
ABSTRACT Doubled haploid technology accelerates the development of fully homozygous maize lines compared with conventional selfing. However, specific protocols for supersweet corn (Zea mays L. var. saccharata), particularly regarding immersion time in antimitotic solutions and temperature during chromosome doubling, remain poorly defined.

Improved Autotetraploid Induction Methods in Four Diploid Wild Peanut Species: Arachis duranensis, A. stenosperma, A. magna, and A. batizocoi

Plant Breeding, EarlyView.
ABSTRACT Peanut (Arachis hypogaea L., 2n = 4x = 40, AABB) is an important legume crop worldwide. Wild peanuts (Arachis spp.) represent a valuable secondary gene pool with diverse disease resistances. However, most wild peanut species are diploid (2n = 2x = 20) and this ploidy barrier is a major obstacle to hybridization and gene introgression.

Tolerância da mamoneira ao herbicida trifluralin em solos com diferentes texturas

Revista Brasileira de Engenharia Agrícola e Ambiental, 2013
A escassez de herbicidas registrados para a cultura da mamoneira ainda é fator limitante para sua expansão. Objetivou-se então, com este trabalho, avaliar a tolerância da mamoneira ao herbicida trifluralin em solos com diferentes texturas.

Environmental Pesticide Exposure in the Etiology of Pediatric Brain Tumors and Leukemia: A Scoping Review of Epidemiological Studies

International Journal of Cancer, Volume 159, Issue 6, Page 1360-1384, 15 September 2026.
ABSTRACT Pediatric cancer is a significant cause of morbidity and mortality in children. The etiologies of pediatric cancer are largely unknown, but environmental pesticide exposures are likely to contribute. Chronic low‐dose exposure to pesticide mixtures through drinking water is a growing concern in agricultural communities.

Impact of crop sequence on cereal yield and soil health in shallow dryland soils

Agronomy Journal, Volume 118, Issue 5, September/October 2026.
Abstract Diversifying small‐grain production systems is encouraged in the US northern Great Plains and similar semiarid regions. Our objective was to determine how crop sequence affected small‐grain crop disease, grain yield, and soil biology in shallow dryland soils of central Montana. Barley (Hordeum vulgare L.), canola (Brassica napus L.), field pea
