Control: Spray with insecticides
(2) Cricket and grasshopper: These insects also defoliate the plant by eating up the leaves and young stems
Control: Spray with insecticides
Diseases of Okra, symptoms and control
(1) Root knot disease: It is caused by eelworm nematode which is found in the soil. read animal pests of crop here
Symptoms: Symptoms include knotting or galling of roots, retarded growth and reduced yield.
(i) Practice crop rotation
(ii) Use resistant varieties
(iii) Treat soil with nematicide e.g. Nemagon
(2) Mosaic disease: It is caused by a virus which is transmitted by piercing and sucking insects. Symptoms include mosaic colouration on the leaves, leading to low yield of the crop.
(i) Spray with insecticide to kill vector
(ii) Uproot and burn infected plants
