The use of nanoparticles (NPs) has generated an alternative pest control. objective was to evaluate the insecticidal effect zinc oxide (ZnO NPs), titanium dioxide (TiO2 and their combination on Bactericera cockerelli (Hemiptera: Triozidae) second-stage nymphs under laboratory greenhouse conditions in tomato. research carried out with leaf immersion bioassay method a complete randomized design, by direct plant spraying block design; both designs, control without NPs added. Mortality recorded...
Chili (Capsicum annuum L.) wilt disease is considered one of the main diseases this crop. It caused by a complex phytopathogens such as Fusarium oxysporum, Rhizoctonia solani, and Sclerotium rolfsii. These fungi have developed resistance to fungicides, resulting in environmental contamination that harms human health. factors motivate search for environmentally safe efficient products control without causing adverse effects ecosystems. Chitosan, which innocuous has antagonistic activity,...
One of the important domestic insects that transmit many pathogens to environment is Periplaneta Americana . The control methods this insect are often ineffective and have caused resistance in these insects. purpose present study was investigate effects contact feeding lethality titanium nanoparticles on In study, different concentrations were prepared for oral treatments P
<p><strong>Background.</strong> Fall Armyworm (FAW) is one of the most damaging agricultural pests found in Western Hemisphere, and it now key on several crops America, Africa, Oceania, Asia; becoming a major threat to food safety many countries, due losses caused farmers.<strong> Objective.</strong> Review current knowledge FAW resistance active ingredients world. <strong>Methodology. </strong>A systematic study was carried out by collecting...
The complications caused by the generation of resistance in psyllid Bactericera cockerelli chemical pesticides, raise need for alternative use products that reduce and ensure better control. species Crotalaria longirostrata is a source secondary metabolites, which show possible activity against insect pests. objective research was to identify compounds crude methanolic extract C. leaves, as well evaluate their biological on B. nymphs. Twenty-five were identified Gas Chromatography coupled...
Las especies de Crotalaria están ampliamente distribuidas en climas tropicales y subtropicales, describiéndose más 700 especies; las cuales, la mayoría son consideradas malezas o invasoras. plantas este género presentan una amplia diversidad metabólica compuestos bioactivos semillas, raíces, tallos, hojas flores; a partir extractos acuosos, etanol, metanol, éter etílico, cloroformo diclorometano, que muestran efecto directo indirecto relacionado con actividades antidiarreicas,...
The objective of this research was the morphomolecular identification species genus Fusarium associated with native and commercial maize genotypes in municipalities Puebla Morelos, Mexico, as well to describe socioeconomic cultural importance cultivation. were isolated from grains stem cuttings purple, brown, dark brown pigmentations. They identified morphomolecularly by using taxonomic keys Dinocapture 2.0 software, DNA extraction CTAB method amplification ITS1 ITS4 region PCR. Four...
Phytotoxicity caused by secondary metabolites of botanical extracts is a drawback in agriculture. The objective this study was to evaluate the phytotoxic effects methanolic Crotalaria longirostrata and Argemone mexicana on germination physiological variables tomato seedlings. results indicated that high doses both (Clong500 Amex500) inhibited seed germination, while their mixture (Cl50 + Am50) promoted 100%. At 30 days after transplanting (dat), plant height increased 15.4% with dose C....
Maize (Zea mays L.) is the most representative crop of Mexico, mainly because its social, cultural, and economic importance. The objective this research was to identify genotypes with natural resistance damage by fall armyworm, Spodoptera frugiperda (J.E. Smith), corn earworm, Helicoverpa zea (Boddie), their relationship ear rot caused Fusarium spp. Link (Nectriaceae). Samples were collected from September November 2019 hybrids native maize in nine plots Puebla Morelos states. Ear pathogens...
El daño causado por el gusano cogollero, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) causa pérdidas de rendimiento en sorgo Sorghum bicolor (L.) Moench (Poaceae) y disminuye valor del cultivo, causando grandes económicas al productor. foliar se analizó bajo infestación natural cogollero líneas experimentales utilizando la escala puntuación Davis, grano evaluó 120 días después siembra. Los datos procesaron con un análisis varianza (ANOVA) una prueba correlación software R...
El silicio (Si), un oligoelemento muy disponible, se distingue por su capacidad de ser fácilmente absorbido, una elevada solubilidad y especificidad en las plantas. Este aspecto resulta esencial, dado que siete los diez cultivos más importantes a nivel mundial son reconocidos acumulación Si respuesta positiva aplicación. Sin embargo, el avance desarrollo agrícolas ven restringidos factores estrés, ya sean bióticos o abióticos. objetivo del presente análisis información consistió examinar la...
Argemone mexicana L. es una maleza, la cual utilizada como planta medicinal. La actividad biológica de esta se ha observado en patógenos virus, hongos, bacterias, protozoos y plagas cultivos agrícolas; dicha atribuye a compuestos flavonoides, glucósidos, terpenoides, fenólicos alcaloides presentes planta. El objetivo del estudio fue evaluar el efecto extracto metanólico A. insecticida sobre Bactericera cockerelli. Se detectaron 13 metabolitos por cromatografía gases acoplada espectrometría...
Monoctenus sanchezi is a sawfly of economic importance in forest management because damage to the foliage white cedar. Mortality by entomopathogenic fungi Metarhizium anisopliae, Beauveria bassiana, and Trichothecium sp. on M. larvae was 98, 60, 36% sixth day. anisopliae may be an alternative for biological control México.
The objective of the research was to evaluate effect relative humidity (RH) and moisture content (MC) on incidence pathogenic fungi seeds Agave lechuguilla, Lippia graveolens, Nolina cespitifera. Seeds were stored 90 days at 60, 75, 80, 85% RH, results processed with a correlation analysis in R software using Spearman test. Higher (FI) found from 10 20% RH; however, between RH MC positive r = 0.311 <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1"> <mi>p</mi> <mo>=</mo> <mn>2.2</mn>...
Se evaluó la efectividad de Pseudomonas donghuensis y Bacillus spp., para el control Fusarium oxysporum Pythium aphanidermatum causantes del ahogamiento plántulas chile en invernadero. comprobó su patogenicidad ocasionar enfermedad se realizaron pruebas antagonismo placas con PDA enriquecido. Mediante confrontación in vitro estos fitopatógenos siete cepas que este esporulado inhibió mayor o menor grado (39.35- 56.24 %) crecimiento micelial F. oxysporum, pero no tuvo efecto alguno P....
El presente estudio tuvo como objetivo determinar la incidencia de F. verticillioides en cuatro genotipos maíz y evaluación cepas Trichoderma biocontrol bajo condiciones laboratorio, 400 semillas asintomáticas tomadas al azar se desinfectaron por inmersión solución hipoclorito sodio 1% 3 min sembraron medio cultivo verde malaquita agar, incubaron a 28 ± 2 ºC dos semanas.

ResumenSitophilus zeamais (Motschulsky) (Coleoptera: Curculionidae) es una plaga responsable de enormes pérdidas granos maíz en postcosecha, estimadas un 60 % durante los primeros seis meses almacenamiento.El objetivo la presente investigación fue evaluar resistencia cinco poblaciones nativo México, frente al daño causado por S. zeamais.Se apreció que las colores 'VAN-Azul' y 'VAN-Variegado' son duras, comparación con el híbrido blanco 'AN-456' 'VAN-Roja' fueron medianamente duras.En libre...
Las enfermedades ocasionadas por hongos son responsables de la mayoría las pérdidas que afectan a plantas. El maíz está expuesto un sin número patógenos lo largo su ciclo fonológico, entre los destacan Fusarium, Ustilago, Aspergillus, Penicillium, etc. Algunos éstos géneros producen sustancias tóxicas denominadas micotoxinas, cuales representan elevado riesgo para salud humana y animales consumen. objetivo este estudio fue evaluar eficacia tres cepas Trichoderma el control pudrición mazorca...
