SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protectionparticularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics:
- Abiotic damage
- Agronomic control methods
- Assessment of pest and disease damage
- Molecular methods for the detection and assessment of pests and diseases
- Biological control
- Biorational pesticides
- Control of animal pests of world crops
- Control of diseases of crop plants caused by microorganisms
- Control of weeds and integrated management
- Economic and social considerations
- Effects of plant growth regulators
- Environmental benefits of reduced pesticide use
- Environmental effects of pesticides
- Epidemiology of pests and diseases in relation to control
- GM Crops, and genetic engineering applications
- Importance and control of postharvest crop losses
- Integrated control
- Interrelationships and compatibility among different control strategies
- Invasive species as they relate to implications for crop protection
- Pesticide application methods
- Pest management
- Plant bioms: for pest and disease control
- Resistance management
- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
