Unveiling Tikka Leaf Disease: A threat to groundnut cultivation.

Introduction

Groundnut, also known as peanut, is an essential crop worldwide due to its versatility and nutritional value. However, like any other agricultural crop, groundnuts are susceptible to various diseases that can hinder their growth and productivity. One such significant disease is Tikka Leaf Disease, which poses a considerable threat to groundnut cultivation. In this blog post, we will delve into the details of Tikka Leaf Disease, including its causes, symptoms, and management strategies.

Causes and Transmission:

The primary cause of Tikka Leaf Disease is a fungus called Cercosporidium personatum. This fungus survives in the soil, crop residues, and infected seeds, waiting for favourable conditions to infect groundnut plants. Moist and humid environments, coupled with warm temperatures ranging from 25 to 30 degrees Celsius, create ideal conditions for the disease to spread rapidly. The disease spreads through wind-dispersed spores, rain splashes, contaminated farm tools, or infected seeds. Additionally, factors such as poor crop rotation, lack of sanitation practices, and the presence of susceptible groundnut varieties contribute to the increased incidence and severity of Tikka Leaf Disease.
