Pick a particular pathogen or pest and describe its life-cycle and the methods by which it can be identified. Compare the suitability of various identification methods, macroscopic, microscopic, biochemical and molecular discussing the advantages and disadvantages of each in relationship to your chosen crop pathogen or pest.

Integrated Crop Protection Identification and quantification of pathogens and pests

Pathogens and pests have effected crop production since the beginnings of agriculture and the consequences of which have been reduced yields and in some cases crop failures.
1) Pick a particular pathogen or pest and describe its life-cycle and the methods by which it can be identified.
2) Compare the suitability of various identification methods, macroscopic, microscopic, biochemical and molecular discussing the advantages and disadvantages of each in relationship to your chosen crop pathogen or pest.
3) Describe the effect of your chosen pathogen or pest on crop yield and discuss the importance of its quantification in terms of the concept of economic threshold?
