Contenido : |
- La pulguilla de la alfalfa provoca daño en otoño y primavera,principalmente en leguminosas forrajeras.
- Se identifica por su forma globosa (1,5-2 mm) y por saltar al ser perturbada
- El daño es fácil de reconocer ya que las hojas quedan transparentes (rae la epidermis).
- El manejo se basa inicialmente en pastorear o cortar la pastura dañada, y revisar luego de 7 días. - Los insecticidas solo se utilizan en casos de daño severo y persistente.
CONSIDERACIONES FINALES
Antes de recurrir al control químico se debe realizar la correcta identificación del daño y del agente causal
del mismo, pues no todos los insectos que habitan nuestras pasturas causan daños. La pastura
debe ser monitoreada periódicamente.
El objetivo de un programa de manejo integrado (MIP) es reducir el daño causado por una plaga a niveles
tolerables, para sostener el equilibrio del ecosistema se debe permitir ciertos niveles de daño.
Se recomienda consultar a su técnico de campo antes de considerar un manejo químico y considerar
estrategias de control cultural. El uso indiscriminado de insecticidas tiene consecuencias directas en el
sistema ecológico del pastizal. |

Abstract: Simplicity of sample preparation, rapidity of the whole analytical procedure and small sample size requirements make near-infrared spectroscopy (NIRS) a very attractive tool for quality screening in wheat breeding programs. Although good results have been achieved for protein content, limited results have been obtained for other quality components such as protein functionality. The suitability of this technology to measure different quality components was studied using different sets of Uruguayan wheat samples n = 73–470#4;. Reference methods included protein composition, hardness, rheological variables and baking tests. Whole and ground wheat grain, and white flour samples were scanned with a Foss (NIRSystem) Model 6500 spectrophotometer. Differences among several math pretreatments for derivatives, gap and segment (smoothing) were
not critical to the quality of the calibration. Results were best when flour was scanned, but were also acceptable using ground wheat and even whole grain. Increasing the size of the scanned sample did not improve results, however duplicating the NIR spectra resulted in better calibrations. Calibration equations obtained were suitable to determine three independent quality components in one simple and fast operation, although with
different accuracies. Protein content was predicted with accuracy similar to that of the reference method (standard error of prediction = SEP = 0.16%; coefficient of determination = r2 = 0#5;99). Hardness calibration was successful only with the ground sample (SEP < 2%#6; r2 = 0#5;85). Results obtained for protein functionality variables had lower coefficients of determination but were sufficient for screening breeding lines.
