Botany optional syllabus and strategy for UPSC and other State PSC

1. BOTANY
For UPSC Examinations (CSE and IFoS)
Strategy by Nikhil Thawal (IFOS AIR 46, CSE 2017 AIR 799) and Ajinkya Yele (Deputy CEO, MPSC
2014 rank 26) with inputs from other Botany optional candidates (esp. Dibya Jyoti Parida Sir).
Serious doubts can be addressed to nikhil.thawal@gmail.com.
Choice of Botany: Choose only if you have background of graduation in life sciences. Otherwise it is
difficult to understand basic concepts. Overlap with GS syllabus is limited (mostly gs3).
Advantage of Botany: A person with science background will feel at home and can avoid the
alienation felt preparing other humanities optionals. Scores have generally been consistent.
How to start:
1. Study the syllabus thoroughly!
2. Analyse previous years question papers (I went as far back as 20 yrs, papers are available on
net) this will help to,
 Access the scope of syllabus (otherwise it is very open ended)
 Trends of the questions
 Prepare Question bank for each topic
3. Look for overlap with your graduation syllabus and pull out those notes.
4. I would advice that one reference book is enough for any one topic (advantage of science
optional, no two ways to look at one fact :D)
5. There is a facebook group called Botany for IAS, it is a small group where you can voice your
queries and find references.
Note making/ Preparation:
Each and every topic/word from the syllabus must be prepared thoroughly.
The format should be,
Topic: Explanation, diagrams, examples, references, contributing scientists with Indian contribution,
uses/applications,
PAPER-I
1. Microbiology and Plant Pathology :
Structure and reproduction/multiplication of viruses, viroids, bacteria, fungi and mycoplasma;
Applications of microbiology in agriculture, industry, medicine and in control of soil and water pollution; Prion
and Prion hypothesis.
Important crop diseases caused by viruses, bacteria, mycoplasma, fungi and nematodes; Modes of
infection and dissemination; Molecular basis of infection and disease resistance/defence; Physiology of
parasitism and control measures. Fungal toxins. Modelling and disease forecasting; Plant quarantine.
Books: Any Graduation level Microbiology Text, specific topics like prions need to be researched, Crop
Diseases (a list of about 20 diseases can be found in any botany text eg Hait prepare diseases in format as per
previous questions, if needed Selective reading of Agrios), Plant quarantine: Prepare India’s mechanisms (asked
in interview)
