Chiarappa. Crop loss assessment due to armyworm is also measured by assigning the score of pest infestation on the leaves with the help of standardized score charts.

The number of grades of such score charts may vary from pest to pest for different crops; usually it indicates the percentage damaged area of the leaves (Dent, ).

Serious losses of up to 5% have been reported in mature plantings caused by the transmission of a nematode resulting in red ring disease. Project Methods The first sugarcane yield loss measurement technique to be used sugarcane is the single plant method in which plants are identified and marked for evaluation.

Disease is assessed once on a large number of individual plants with a variety of disease severities. Yield is determined at maturity, collected and grouped by disease levels to obtain a mean yield for that group.

The techniques employed in crop loss assessment provide a framework useful in identifying the causes and magnitude of crop losses, and a basis for the evaluation of control options.

Causes of crop losses Direct crop losses caused by diseases and pests may be measured as the proportion of crop not sold. In addition to losses in yield and quality in the field and later during storage and transport, there are many, less tangible ways in which File Size: 93KB.

The review systematically finds a total of 62 empirical case studies from the past three decades. The number of case studies has recently been increased because of increased availability of remote sensing data.
