Sample Question 1
Plant Pathology & Crop Protection MEDIUM • MULTIPLE_CHOICE
Karnal bunt of wheat is caused by which fungal pathogen?
A Tilletia indica (Neovossia indica)
B Puccinia striiformis
C Ustilago tritici
D Fusarium oxysporum
✓ Correct Answer: A - Tilletia indica (Neovossia indica)
📖 Step-by-Step Solution & Conceptual Rationale:
Tilletia indica infects wheat florets, converting kernels into fishy-smelling teliospores.
Sample Question 2
Plant Pathology & Crop Protection EASY • MULTIPLE_CHOICE
Cotton Leaf Curl Disease (CLCuD) is caused by a begomovirus transmitted by:
A Jassids
B Thrips
C Whitefly (Bemisia tabaci)
D Aphids
✓ Correct Answer: C - Whitefly (Bemisia tabaci)
📖 Step-by-Step Solution & Conceptual Rationale:
Bemisia tabaci vector persistently transmits CLCuV, causing leaf curling and enations.
Sample Question 3
Plant Pathology & Crop Protection EASY • MULTIPLE_CHOICE
Late blight of potato is caused by which oomycete organism?
A Pythium aphanidermatum
B Phytophthora infestans
C Alternaria solani
D Rhizoctonia solani
✓ Correct Answer: B - Phytophthora infestans
📖 Step-by-Step Solution & Conceptual Rationale:
Phytophthora infestans rapidly blights foliage and causes brown tuber rot in cool moist weather.
Sample Question 4
Plant Pathology & Crop Protection MEDIUM • MULTIPLE_CHOICE
Bordeaux mixture is a protective fungicide composed of:
A Zinc sulfate and urea
B Iron sulfate and lime
C Copper sulfate and Slaked lime (CuSO4 + Ca(OH)2)
D Copper oxychloride and sulfur
✓ Correct Answer: C - Copper sulfate and Slaked lime (CuSO4 + Ca(OH)2)
📖 Step-by-Step Solution & Conceptual Rationale:
Bordeaux mixture precipitates copper hydroxide, providing broad-spectrum protective fungicidal action.
Sample Question 5
Plant Pathology & Crop Protection MEDIUM • MULTIPLE_CHOICE
Citrus canker is a quarantine bacterial disease caused by:
A Ralstonia solanacearum
B Erwinia amylovora
C Pseudomonas syringae
D Xanthomonas citri subsp. citri
✓ Correct Answer: D - Xanthomonas citri subsp. citri
📖 Step-by-Step Solution & Conceptual Rationale:
Xanthomonas citri causes raised corky lesions with oily halos on citrus leaves and fruits.
Sample Question 6
Plant Pathology & Crop Protection MEDIUM • MULTIPLE_CHOICE
Loose smut of wheat is internally seed-borne and caused by:
A Puccinia graminis
B Septoria tritici
C Tilletia caries
D Ustilago tritici
✓ Correct Answer: D - Ustilago tritici
📖 Step-by-Step Solution & Conceptual Rationale:
Ustilago tritici mycelium resides dormant inside the embryo of infected seeds.
Sample Question 7
Plant Pathology & Crop Protection HARD • MULTIPLE_CHOICE
Which systemic fungicide is widely used as a seed dressing to control loose smut of wheat?
A Carboxin / Tebuconazole / Difenoconazole
B Sulfur powder
C Bordeaux mixture
D Copper sulfate
✓ Correct Answer: A - Carboxin / Tebuconazole / Difenoconazole
📖 Step-by-Step Solution & Conceptual Rationale:
Systemic triazoles and carboxin penetrate the germinating seed to eradicate internal fungal mycelium.
Sample Question 8
Plant Pathology & Crop Protection MEDIUM • MULTIPLE_CHOICE
Root-knot nematodes belong to which genus?
A Pratylenchus species
B Xiphinema species
C Meloidogyne species
D Heterodera species
✓ Correct Answer: C - Meloidogyne species
📖 Step-by-Step Solution & Conceptual Rationale:
Meloidogyne juveniles invade root tips, inducing giant cells and characteristic root galls.
Sample Question 9
Plant Pathology & Crop Protection EASY • MULTIPLE_CHOICE
The 'Disease Triangle' concept states that plant disease development requires:
A Host and fertilizer only
B A susceptible host, a virulent pathogen, and a favorable environment
C Only seed and water
D Only pathogen and soil
✓ Correct Answer: B - A susceptible host, a virulent pathogen, and a favorable environment
📖 Step-by-Step Solution & Conceptual Rationale:
Disease manifests only when all three components interact favorably over time.
Sample Question 10
Plant Pathology & Crop Protection HARD • MULTIPLE_CHOICE
Which fungal group produces sexual spores inside a sac called an ascus?
A Ascomycota
B Zygomycota
C Basidiomycota
D Oomycota
✓ Correct Answer: A - Ascomycota
📖 Step-by-Step Solution & Conceptual Rationale:
