Fosfitos en la producción de fresa.
Provedor de dados: 32
Autores: Estrada Ortiz, Elías.
El efecto de fosfitos en plantas depende fuertemente del estado nutrimental de fósforo en el organismo vivo, ya que plantas deficientes en fósforo son vulnerables a aplicaciones de fosfitos (H2PO3-). La presente investigación se realizó con el objetivo de determinar el efecto del suministro de distintos porcentajes de H2PO3- en la solución nutritiva, sobre el crecimiento, rendimiento y calidad de fruto en fresa. El experimento se realizó en un invernadero tipo túnel del Colegio de Postgraduados, en Montecillo, México, utilizando riego por goteo y tezontle como sustrato, en un diseño experimental en bloques al azar generalizado. Se modificó la solución nutritiva Steiner para utilizarla, en una primera fase al 50%, y al comenzar la fructificación se aumentó...

Abstract  The aim of this study was to evaluate the anthracnose intensity in ‘Prata-Anã’ banana with the application of three phosphite formulations in two application intervals in the developing banana bunches and to evaluate the physical and chemical characteristics of fruits. In the field, in addition to producer management, three phosphite formulations were evaluated: FCu1 (4% Cu + 20% P2O5), FCu2 (4% Cu + 22% P2O5) and FK (42% P2O5 + 27.7% K2O) sprayed on banana bunches at different application frequencies: four and eight times. The experiment was carried out in a randomized blocks design following a 5 x 2 factorial scheme, with 3 phosphite formulations, pure water and no application and two application intervals. Pure water and no application were...

Induction of resistance and chemical management of mildew and Asian rust in soybean cultivation
Provedor de dados: 109
Autores: Grigolo,Daniel Claudio; Possenti,Jean Carlo; Mazaro,Sergio Miguel; Silva,Marcieli da; Guollo,Karina.
Abstract Soybean (Glycine max (L.) Merrill) is one of the most cultivated in Brazil and has lost productivity due to the attack of disease pests. Thus, it is necessary to develop new technologies capable of reducing damages caused by such biological agents. The aim of this work was to evaluate whether the chemical management of ‘eyespot’ and the induction of resistance through the use of phosphites and acibenzolar-s-methyl (ASM), in association with commercial fungicides, affect the quality of soybean seeds. The study was conducted in the field, during two consecutive harvests in Dois Vizinhos, Paraná, Brazil, and a randomized blocks experimental designs was used. The response-variables evaluated were yield components, disease severity through specific...

The effects of Coda Radimax (CR), Coda Humus-PK (CH) and Coda Vit (CV) on the induction of resistance for Meloidogyne incognita in sugarcane (Saccharum sp.) varieties (RB92579, RB863129, RB867515) through nematode reproduction, plant development and root anatomy analysis, emphasizing the differences of the lignin deposition, and cortex-vascular cylinder proportions were investigated. In 90 days after inoculation with eggs of M. incognita, CR reduced the number of eggs per root system in all the sugarcane varieties; CH and CV reduced eggs density in RB867515; CR increased stalk number in RB92579 and fresh weight of shoots in RB863129 and RB92579; CH increased plant height in RB92579 and fresh weight of shoots in RB92579 and RB867515, CV affected fresh weigh...
