30/07/2022Posted on

It is a disease caused by mycoplasma. The disease is spread through leaf hoppers. This disease is also called sterile disease. This disease can reduce the yield of brinjal by up to 40 percent. Plants affected by this disease become dwarf in size. And there are other symptoms of the disease For example, there is a discolouration and rudiment of the leaves, or the leaves are deformed, small and thick etc. and the new leaves shrink and become smaller and the leaves seem to be stuck to the stem. Due to which brinjal plants do not bear fruit, even if fruits do come, they are very hard. The plant becomes bushy.

Management:

Remove and destroy infected plants Dip the seedlings in 0.2% Carbofuran 50 STD solution before transplanting (for control insect vectors) Spray Dimethoate 0.3%

For biological control, spray briged B (BEAUVERIA BASSIANA 1.15% WP) @1 kg/acre @ 150-200 liters of water.
