Question: What is the role of the nematode in Tundu disease of wheat?
Options:
Vector
Aggravator
Incitant
Pathogen
✅Explanation:
Tundu disease: This is a complex disease of wheat caused by both a nematode (Anguina tritici) and a bacterium (Clavibacter tritici). It results in distorted and sticky spikes, often with a yellow exudate that turns white when dry.
Vector: An organism that transmits a disease-causing agent (pathogen) from one host to another.
Anguina tritici: This nematode serves as a vector for Clavibacter tritici, the bacterium responsible for the Tundu symptoms. The nematode creates galls in the wheat heads, providing an entry point and a protected environment for the bacteria to multiply.
Tundu disease is also known as yellow ear rot disorder.
It is caused by nematodes and bacteria.

🔑Key Points:
The factors of this disease are Corynebacterium tritici bacteria and Enzuina Titriki nematode.
The 'tundu' disease is characterized by twisting of the stem, distortion of the earhead and rooting of the spikelets.
The nematode involved in the disease causes wrinkling, twisting and various other distortions of the leaves and stem.
As a result of this disease, the infected plants are shorter and thicker than the healthy plants.
