Diagnóstico general y servicio prestado en la Cooperativa Agrícola Integral Unión de 4 Pinos R.L. Santiago Sacatepéquez, Guatemala C.A. y evaluación de Boscalid + Pyraclostrobin en la producción y prolongación de vida en anaquel del zucchini (Cucúrbita pepo L. subsp. pepo.)

La presente investigación se realizó en a Cooperativa Agrícola Integral Unión de 4 Pinos, R.L., Finca La Suiza, San Lucas Sacatepéquez, mediante el diagnóstico realizado en Finca La Suiza, área productora de Cooperativa Agrícola Integral Unión de 4 Pinos, determinando que la importancia de investigar el uso de nuevas tecnologías que aumenten la vida de anaquel del zucchini. La investigación consistió en la evaluación del efecto de los ingredientes activos Boscalid+Pyraclostrobin en la producción y prolongación de vida en anaquel del zucchini, para lo cual el ensayo fue dividido en dos etapas, la primera la producción en campo y la segunda el manejo postcosecha en planta empacadora. La primera parte fue realizada en Finca La Suiza, para lo cual se elaboró un plan de manejo fitosanitario, tomando como base el plan de manejo fitosanitario para el cultivo de zucchini Departamento Agrícola 2009, a la cual se incluyeron las aplicaciones de la estrobilurina (Boscalid+Pyraclostrobin) se evaluaron cuatro tratamientos, de los cuales uno era el testigo absoluto, dos tratamientos con 2 y 3 aplicaciones de la estrobilurina (Boscalid+Pyraclostrobin) en diferentes etapas fenológicas del cultivo y un cuarto tratamiento el manejo tradicional del Departamento Agrícola, asi como manejo postcosecha del producto, el cual fue sometido a un procedimiento de clasificación, lavado, desinfección, empaque y colocación en cuarto frio (4ºC) para determinar los días de vida en anaquel del zucchini

2D histograms showing the distribution of the results obtained for 100 000 of the isotopic signatures from the modelled Almaco Jack in δ-space for the common species (Part 1) for dietary generalists and habitat specialists (D_gH_s) and dietary specialists and habitat generalists (D_sH_g).

<p>Individual histogram greyscale bars indicate the relative frequency for each class.</p

Comparison of source proportion estimates for each of the common prey species and Shannon-Wiener information measure (H) means and variances in p-space, between mixing models (SISUS, IsoSource and MixSIR) for Part 1 and 2.

<p>Includes mean proportion estimates, and Shannon-Wiener means and variances for all three models, elucidated in bold.</p

Comparison of variances in δ-space (for both δ¹³C and δ¹⁵N) with p-space (Shannon-Wiener information measure) for models using the common prey species (Part 1) and models using the common prey species and incorporated distance between sites (Part 2).

Tukey's post hoc results comparing variances between models using the common prey species and incorporating distance between sites (Part 2).

<p>NS: no significant difference; asterisks indicate significant differences at *p<0.05, **p<0.01 and ***p<0.001.</p

2D histograms showing the distribution of the results obtained for 100 000 of the isotopic signatures from the modelled Almaco Jack in δ-space incorporating distance between sites for the common prey species (Part 2), and the entire prey assemblages (Part 3).

<p>Models include those for dietary generalists and habitat generalists (D_gH_g), dietary specialists and habitat specialists (D_sH_s) (Part 2 only) and dietary generalists and habitat specialists (D_gH_s) (Part 3 only). Individual histogram greyscale bars indicate the relative frequency for each class.</p

Mean and variance of δ¹³C and δ¹⁵N for models of simulated Almaco Jack populations.

<p>Those models in bold elucidate mean values for each population based on diet (specialist vs. generalist) and habitat (Wellhead). Where a model consists of numerous variations (different specialisations) a ‘Pooled’ value is provided as an accumulative mean value for the model. Models for Part 1 used the four common prey species. Models for Part 2 used the common prey species and incorporating distance between sites. Models for Part 3 used the entire prey assemblage.</p
