Abstract:
Root knot nematode is currently wreaking havoc on guava cultivation and is considered a severe danger. The current problem was taken into consideration and an investigation was planned and conducted during the survey that was taken up at Karadkal, Mudgal, Gudihal villages of Lingasuguru taluk. Representative samples of soil and root were collected from the affected plot of respective villages. Plant development was significantly reduced in the nematode-infested plant, as well as the absence of fine roots, a poorly developed root system, and a drop in quality and quantity of fruit. Tiny leaves, browning leaves, leaf loss, and growth retardation are indicators of a seriously diseased plant, while roots are twisted by little and large numerous galls, causing tree death. Root-knot nematodes may have caused the heavily galled roots in the affected seedlings. The nematode Meloidogyne enterolobii has been connected to a decrease in guava growth in Lingasugur surrounding villages for the first time. Root samples were taken from infected guava plants, and mature females were isolated and analysed separately.
