Fusarium oxysporum f. sp. vasinfectum

Culture medium	Comprehensive PDA agar (CPDA): potato boil 1.0L, glucose 20.0g,KH2PO4 3.0g,MgSO4 · 7H2O 1.5g, vitamin B1 trace, agar 20.0g,pH 6.0±0.2. Sterilization at 121 ℃ for 15min. Potato boiling liquid: weigh 200g of peeled potato pieces, boil in boiling water for 30min, and collect the filtrate to a constant volume of 1.0L.
Subculture procedure	(1) Prepare 1-2 pieces of PDA plate; (2) sterilize the surface of test tube for the agar slant, open it in the biosafety cabinet; (3) cut into the pieces with aseptic inoculation hoe and inoculation shovel (see attached page). the size of square pieces is 0.5 × 0.5cm2; (4) lay flat the small pieces to the center of the agar plate; (5)put the plates under the above culture conditions, and the strains can be used when they grow.
Growth conditions	28 ℃,5-7 days, aerobic
Storage conditions	-196
morphology	Small filamentous fungi, with obvious colonies, white, dense and vigorous hyphae on the integrated PDA medium, spreading to the edge of the plate, and yellowish on the back of the medium.
application	Cotton blight pathogen
Sharing mode	Public welfare sharing
