questions: query regarding management of wilt in brinjal field. 
 answers:  first of all you have to do the bacterial test. for that cut a piece of twig from the affected plant, put into a glass of clean water and keep it for 30 minutes. after that if you have noticed that the water become yellowish white then you have to apply streptomycin/ streptocyclin 2gram/10liter of water in the root portion  and if the water remain same then you can use any fungicide like captaf/glyodin/ carboxin/captan 3 gram/liter of water.
