Describe the maturity index of maize?(2) which vector transmit maize steak virus disease and how?

The maturity index of maize refers to the stage of development at which the maize crop is ready for harvest. This is typically determined by factors such as the color and texture of the kernels, as well as the moisture content of the plant.

Maize streak virus disease is transmitted by the African maize leafhopper (Cicadulina mbila) vector. The leafhopper feeds on infected maize plants, acquiring the virus in the process. The virus is then transmitted to healthy plants when the leafhopper feeds on them, injecting the virus into the plant's vascular system. This transmission process can lead to the spread of the disease throughout maize fields.
