The leafhopper is a small insect (its size is similar
to that of a sesame grain). It is also named empoasca or loritoverde. The
leafhopper lives on the lower surface of bean leaves. Its body is the shape of
a large wedge. The colour of the adult and the young varies from green to light
green. They walk on one side. The leafhopper sucks sap from the leaves, which
become yellow. The edges curl down and plants weaken which greatly reduces bean
The leafhopper transmits the golden mosaic virus. It
must be detected early for control.
Rain affects the leafhoppers as raindrops can kill
Leafhoppers can also live in the undergrowth.
Sowing during the rainy season reduces leafhopper attacks
- Eliminate host undergrowth and stubbles from previous cultivation
- The opportune detection of leafhopper is important in drought periods, especially
before flowering until pods are formed
- Practise crop rotation
- Spray with systemic and contact insecticides such as Imidacloprid 70 mL
in 20 L water and Abamectin 16 mL in 20 L water, interspersing each application
every 15 days
There is no chemical
treatment for the virus.
When using a pesticide, always wear protective clothing and follow the instructions on the product label, such as dosage, timing of application, and pre-harvest interval.
