MAIZE STREAK DISEASE
Maize streak disease (
Photo 6
) is caused by the maize streak virus. It is
a complex disease, where the virus is transferred by a leafhopper. The
environmental conditions affect the incidence, survival and distribu-
tion of the leafhopper – which determines the incidence and intensity
of the disease.
Maize streak virus cannot be controlled with fungicide. Controlling
maize streak virus involves a combination of measures to reduce or
limit the risk of the disease. Although insecticides are effective as seed
treatments and prevent the leafhoppers from feeding on the young
plants and transferring the virus, they are no guarantee or instant solu-
tion for the disease.
CONCLUSION
There are various other leaf diseases that were not mentioned in this
article because they are less common or occur sporadically. However,
this does not mean that they cannot cause huge yield losses under the
right conditions. In order to react timeously, it is wise to still consult a
good source or expert if suspicious symptoms are observed.
