grassy shoot of sugarcane is a major threat to sugarcane production, causing significant yield losses. It is caused by a group of phytoplasmas, microscopic organisms that live within the plant's phloem tissue and disrupt nutrient flow.
- Type of Infestation: Fungal Disease
- Common Name: Grassy Shoot Disease
- Affected Parts Of the plant: Shoot
- Temperature: SGSV thrives in warm temperatures, with an optimal range of 25-30°C (77-86°F). Cooler temperatures can slow down the spread of the virus, while excessively hot temperatures can also be detrimental.
- Humidity: High humidity levels (above 70%) favor the survival and transmission of SGSV by leafhoppers, the main insect vectors of the virus.
- Proliferation of tillers: Infected sugarcane plants exhibit an abnormal growth of tillers, giving them a "grassy" appearance. This is due to the disruption of hormonal balance in the plant.
- Chlorosis: Leaves lose their green color due to reduced chlorophyll production, turning pale yellow or white. This is because phytoplasmas hinder the plant's ability to photosynthesize.
- Stunted growth: The overall growth of the sugarcane plant is stunted, with shorter internodes and thinner stalks.
- Absence of cane formation: In severe cases, the plant may not be able to form any cane at all.
