Uncertainty on nitrogen emission data of smallholder greenhouse tomato growers in the Andean tropics of Colombia
Smallholder growers carry out greenhouse tomato production in the Colombian
Andes applying sub-optimal management practices in regions characterized by large
between growing cycle variations in soil properties and climate ...
Estandarización de un bioensayo y evaluación preliminar de tres formulaciones comerciales de Bacillus thuringiensis sobre Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)
La polilla del tomate (Tuta absoluta Meyrick; Lepidoptera: Gelechiidae) es una de las plagas más devastadoras
del tomate en Colombia y países suramericanos, produciendo pérdidas de hasta el 100% en cultivos sin protección. ...
Environmental savings in tomato production under optimal agrochemicals management: a modeling approach
The use of agrochemicals has been recognized as one of the main environmental burdens in agriculture. Actual management practices aggravate pollution issues due to overdosing and untimely applications, even more if farmers ...
Adaptation of a leaf wetness duration model for tomato under Colombian greenhouse conditions
Greenhouse tomato production uses structures that protect
crops from extreme environmental conditions; however, the
climate inside Colombian greenhouses is often not optimal and
crops are susceptible to attack by fungal ...
Molecular and biological characterization of native Bacillus thuringiensis strains for controlling tomato leafminer (Tuta absoluta Meyrick) (Lepidoptera: Gelechiidae) in Colombia
Twenty-eight soil samples were obtained from
open fields and greenhouses used for tomato cultivation in
various regions of Colombia. For functional characterization, 99 Bacillus thuringiensis (Bt) strains were isolated ...
The greenhouse effect in the high tropics of Colombia: A modeling approach
is discussed as an example. The high altitude tropical climate of the Bogota
plateau is characterized and the necessity for protected tomato cultivation is
explained. As a consequence of the specific climate conditions ...
Datasets of the environmental factors and management practices of the smallholder tomato production systems in the Colombian Andes
Datasets presented here were employed in the main work “Understanding
the heterogeneity of smallholder production systems
in the Andean tropics e The case of Colombian tomato growers”
Gil, et al., 2019. In this region, ...
Evaluation of pesticide residues in open field and greenhouse tomatoes from Colombia
The presence of 17 pesticide residues was determined in just-picked tomatoes coming from open field
and greenhouse farms in Colombia. Pesticide residues were quantified through a multiresidue method
using ultra performance ...
Effect of aluminized screens on greenhouse tomato (Solanum lycopersicum L.) production systems at the high tropical conditions
Currently, Colombia has 3,390 ha cultivated with tomato under greenhouse conditions characterized by their low level of
climate control. In areas where low night temperatures limit tomato production, we evaluated the ...
Monitoring of pesticide residues in tomato marketed 1 in Bogota, Colombia
Worldwide, the presence of pesticide residues in vegetables has been extensively characterized. In Colombia, tomato is among the most consumed horticultural commodities; however, the presence of pesticide residues in tomato ...
