FIELD: agriculture.
SUBSTANCE: at stage of vegetable samples' homogenisation hydroxy derived from benzoic acid is added to a lytic buffer in amount of 20-30 mg for a sample. The lytic buffer contains 4 mg guanidine hydrochloride, 0.2 M sodium acetate, 25 mM EDTA , 2.5% kollidon, 20% sarcosyl.
EFFECT: efficiency upgrading RNA's educing, more successful PCR's process and revealing of viruses in vegetable sphere.
