“…Both scales, the one presented here and the one described in Ref. [2], include 6 severity levels (p0 to p5), but they differ in the lowest severity level observed in the field. Under the high disease pressure observed in the experiments here described there was no presence of healthy plants (Level 0).…”

In the last century, more than a hundred of cultivars were used in the cotton production system in Colombia. Breeding for cultivars adapted to tropical environments had been the main purpose of the Colombian agricultural research institutions dedicated to cotton. Data describing yield and fiber quality traits of these cultivars (and the introduced ones mainly from USA) is scattered across grey literature which reduces chances of discovering, accessing and assessing this information.This data article contains databases describing i) Colombian and introduced Upland cotton cultivars used in Colombia and ii) ramulosis-resistance scores of lines developed by the Colombian breeding program. The first database was constructed from data extracted from grey literature mainly produced by ICA and CORPOICA (rebranded today as AGROSAVIA), the Colombian agricultural research agencies. The second one describes the Cereté lines (LCER) database. These advanced breeding lines were developed for improved yield performance in tropical environments, specifically monsoon and savanna climates. The LCER dataset also describes the ramulosis field resistance of these cultivars. Ramulosis is an endemic disease in South America caused by Colletotrichum gossypii var. cephalosporioides . The data in this article supports and augments information presented in the research articles [1]: and [3].

“…"Take no action" is the initial state of the system (before the intervention). It provides a baseline for the comparison of the control actions under uncertain pest infestation levels (Moore et al 2011). As the economic outcome (return) of each control strategy changes at different pest infestation levels and crop growth stages, strategy comparisons require a representation of these combinations.…”

Profitability of farm-scale management strategies against the boll weevil in the tropics: case study from the Colombian Caribbean

et al. 2021

Decision making in pest management is a challenging task. While pest dynamics are often quite uncertain, such decisions are often based on tenuous assumptions of certainty (economic injury levels and marginal utility approximations). To overcome such assumptions and adequately consider uncertainty, we apply decision analysis to evaluate management strategies used by farmers in the Colombian Caribbean against the boll weevil (BW). We represent the decision to protect the crop using partial budget analysis. This allows us to capture key properties of BW control strategies, while accounting for uncertainty about pest infestation pressure, control effectiveness and cotton yield and price. Our results indicate that proactive pest management is more efficient than reactive control given the current BW infestation pressure. However, farmers may prefer the reactive strategy, since they have experienced seasons with low infestation pressure where no insecticide applications were required. The proactive strategy, in contrast, requires scheduled pesticide applications in all years. Results show that in seasons with high infestation pressure the expected revenues of the reactive strategy tend to decrease, mainly because more spray applications are required when fields are heavily infested by the weevil. Value of information analysis revealed that uncertainties related to the start of the infestation, loss damage rate and attainable yield have the greatest influence on the decision recommendation for crop protection. Narrowing these key knowledge gaps may offer additional clarity on the performance of the current management strategies and provide guidance for the development of strategies to reduce insecticide use. This is particularly important for the promotion of the proactive strategy, which, under the current infestation pressure, has potential to reduce insecticide use. While economic injury levels can only be applied to responsive measures, our approach of partial budget analysis under uncertainty allows us to assess and compare both responsive and preventive measures in the same methodological framework. This framework can be extended to non-pesticide control measures.

“…Síntomas de encrespamiento están comúnmente asociados a virus, sin embargo existen reportes de ascomicetos capaces de producir esta sintomatología, por ejemplo el encrespamiento de hojas del durazno causado por Taphrina deformans (Moscatello et al, 2017) , y el de hojas de algodón causado por Colletotrichum gossypii var. cephalosporioides (Moreno-Moran & Burbano-Figueroa, 2017) . Taphrina deformans puede ocasionar la muerte de los árboles de durazno como resultado del excesivo consumo de azúcares por el patógeno y la pérdida de área fotosintética asociada a la defoliación (Moscatello et al , 2017) .…”

Los ecosistemas alpinos en el trópico son islas en las alturas, ambientes sin continuidad espacial ubicados a altitudes de más de 3000 - 5000 msnm, entre la línea de bosque y la línea de nieves perpetuas. Los ecosistemas alpinos tropicales de mayor extensión y riqueza se encuentran distribuidos en las regiones montañosas ecuatoriales de Sudamérica, África Oriental y Nueva Guinea. Estos ecosistemas son dominados en cada continente por plantas de rosetas gigantes de varias especies vegetales no relacionadas filogenéticamente. Esta extraña arquitectura vegetal es el resultado de la adaptación al proceso diario de congelamiento y descongelamiento que ocurre en los hábitats alpinos tropicales y que ha resultado en convergencia evolutiva. En los Andes, estos ecosistemas han recibido el nombre de páramos y están dominados por rosetas gigantes del género Espeletia. En la última década se han reportado multiples problemas fitosanitarios para especies de este. Este trabajo desarrolla un modelo conceptual que recolecta, organiza y combina el conocimiento (conceptos e hipótesis propuestas por varios grupos de investigación) relacionado con la muerte y declive de los frailejones en las ecosistemas alpinos tropicales de los Andes del Norte. Este análisis permite identificar las brechas de conocimiento actuales para este problema, las hipótesis propuestas para explicarlo y un marco conceptual para el desarrollo de las estrategias futuras de monitoreo y manejo de estas afectaciones. Este trabajo ha encontrado que los trabajos que han intentado explicar las afectaciones observadas en el género Espeletia, son acciones aisladas para describir y relacionar los síntomas de herbivoría, daño foliar y muerte en pie; y recomienda que estas observaciones deben ser explicadas en un marco más amplio que permita establecer su rol en el declive y muerte de los frailejones. Adicionalmente, estas infestaciones de plagas y enfermedades deben ser consideradas en los modelos de predicción de desplazamiento que sufrirán las poblaciones de Espeletia como resultado del cambio global. Estas interacciones pueden exacerbar el efecto del cambio climático e incrementar los riesgos de reducción de la población y extinción.
