Questions and Answers

1.

Leaves and fruits are clustered in this disease of sapota
- A.
  
  Flat limb
- B.
  
  Red rust
- C.
  
  Tristeza
- D.
  
  Dendrophthe
Correct Answer
A. Flat limb

Explanation
In the disease of sapota called "flat limb," the leaves and fruits are clustered together. This clustering of leaves and fruits is a characteristic symptom of flat limb disease, which affects the growth and development of the sapota tree. The term "flat limb" refers to the flattened appearance of the affected branches, which may be caused by various factors such as fungal or bacterial infections, nutrient deficiencies, or environmental stress. However, without further information, it is difficult to determine the exact cause of flat limb disease in sapota trees.

________ is the non parasitic disease of mango.

Correct Answer
sooty mold

Explanation
Sooty mold is a non parasitic disease of mango. This disease is caused by a fungus that grows on the honeydew excreted by certain insects, such as aphids or scales, that infest mango trees. The fungus forms a black, powdery coating on the leaves, branches, and fruit of the mango tree, giving it a sooty appearance. While sooty mold does not directly harm the mango tree, it can reduce photosynthesis and affect the overall health and productivity of the tree. Therefore, sooty mold is considered a non parasitic disease of mango.

Red scaled onions are resistant to ________ disease .

Correct Answer
smudge

Explanation
Red scaled onions are resistant to smudge disease. Smudge disease is a fungal disease that affects onions and causes dark, smoky patches on the outer scales of the bulbs. Red scaled onions, however, have a natural resistance to this disease, meaning they are less likely to be affected by it compared to other varieties of onions. This resistance is likely due to genetic factors that make red scaled onions more capable of fighting off the fungal infection.

One of the following citrus disease occurs in symbiotic association with inscects
- A.
  
  Tristeza
- B.
  
  Felt
- C.
  
  Greening
- D.
  
  Gummosis
Correct Answer
B. Felt

Explanation
Felt is the correct answer because it is a citrus disease that occurs in symbiotic association with insects. This disease is caused by a bacterium called Spiroplasma citri, which is transmitted by leafhoppers. Felt affects the phloem tissue of citrus trees, causing yellowing, stunting, and a "felt-like" appearance on the leaves. The insects act as vectors for the bacteria, spreading the disease from tree to tree.

A guava disease of unripe fruit is
- A.
  
  Cercospora spot
- B.
  
  Wilt
- C.
  
  Canker
- D.
  
  Anthracnose
Correct Answer
C. Canker

Explanation
Canker is a disease that affects unripe guava fruit. It causes the formation of lesions or ulcers on the fruit, leading to discoloration and decay. Canker is commonly caused by bacterial or fungal infections and can significantly reduce the quality and yield of guava crops. It is important for farmers to identify and manage canker to prevent further spread and damage to the fruit.

The banana disease which characteristically shows atrophy symptoms
- A.
  
  Sigatoka
- B.
  
  Black spot
- C.
  
  Anthracnose
- D.
  
  Bunchy top
Correct Answer
D. Bunchy top

Explanation
Bunchy top is the correct answer because it is a banana disease that is known for causing atrophy symptoms. Atrophy refers to the wasting away or degeneration of tissues or organs, and this is a characteristic symptom of bunchy top disease in bananas. Sigatoka, black spot, and anthracnose are also banana diseases, but they do not typically exhibit atrophy symptoms.

7.

Citrus leaf miner is associated with following disease
- A.
  
  Canker
- B.
  
  Tristeza
- C.
  
  Felt
- D.
  
  Greening
Correct Answer
A. Canker

Explanation
The correct answer is canker. Canker is a disease commonly associated with citrus trees, caused by various fungi and bacteria. It affects the bark, branches, and fruit of the tree, causing lesions and cankers to form. These cankers disrupt the flow of nutrients and water within the tree, leading to wilting, dieback, and ultimately, the death of the tree if left untreated. The citrus leaf miner, on the other hand, is a pest that damages the leaves of citrus trees by creating tunnels within them, but it is not directly associated with canker.

Rate this question:
8.

Which disease of mango is of post harvest importance
- A.
  
  Anthracnose
- B.
  
  Sooty mold
- C.
  
  Rust
- D.
  
  Bacterial leaf spot
Correct Answer
A. Anthracnose

Explanation
Anthracnose is a fungal disease that affects mangoes after they have been harvested. It causes dark lesions on the fruit, leading to rotting and spoilage. Anthracnose is of post-harvest importance because it can significantly reduce the shelf life and quality of mangoes, making them unsuitable for consumption or sale. It is a common disease in mango-producing regions and can result in significant economic losses for farmers and exporters. Control measures such as proper handling, storage, and the use of fungicides are necessary to prevent the spread and damage caused by anthracnose.

Lopsided fruits in citrus is a characteristic symptom of________ disease

Correct Answer
citrus greening

Explanation
The presence of lopsided fruits in citrus is a characteristic symptom of citrus greening disease. This disease, caused by a bacterium called Candidatus Liberibacter, affects citrus trees and causes the fruits to become misshapen and uneven in size. The bacteria are transmitted by an insect called the Asian citrus psyllid. As the disease progresses, the fruits may also develop a blotchy green color and a bitter taste. Citrus greening is a serious threat to the citrus industry as it can lead to reduced fruit production and eventual death of the tree.

An example of disease caused by FVB is
- A.
  
  Citrus greening
- B.
  
  Sesamum phyllody
- C.
  
  Anthracnose of mango
- D.
  
  Spotted wilt of tomato
Correct Answer
A. Citrus greening

Explanation
Citrus greening is a disease caused by the bacteria Candidatus Liberibacter asiaticus, which is transmitted by the Asian citrus psyllid insect. This disease affects citrus trees and leads to the yellowing and decline of leaves, stunted growth, and the production of small, bitter, and misshapen fruits. It is a devastating disease that has caused significant economic losses in the citrus industry worldwide. The bacteria multiply in the phloem vessels of the tree, disrupting the flow of nutrients and causing the characteristic symptoms. Control measures include the use of insecticides to manage the psyllid population and the removal and destruction of infected trees.
