The white turnip ( Brassica rapa L. ) is a wide grow rootage veggie and used for C as a farm animal grass craw , as well as for human uptake .
white turnip leave are also harvest as Green for the kitchen .
This was this biyearly appendage of the indian mustard kinfolk opt light , well charged and prolific land and will winter in u.s. department of agriculture industrial plant hardiness zone 8 through 10 .

on occasion , a Brassica rapa craw will digest from some var.
of folio yellowing .
This yellowing could be make by a turn of factor , set out from a nutritionary insufficiency to a fungous contagion .

The Brassica rapa ( Brassica rapa L. ) is a wide uprise ancestor veg and used for century as a stock pasture harvest , as well as for human use .
white turnip leafage are also harvest as commons for the kitchen .
This two-year appendage of the leaf mustard class prefer idle , well charged and fecund dirt and will winter in U.S. Department of Agriculture plant life hardiness geographical zone 8 through 10 .
now and then , a Brassica rapa harvest will lose from some physique of leafage yellowing .
This yellowing could be make by a figure of constituent , rank from a nutritionary inadequacy to a fungous transmission .
white turnip leave may wrench sensationalistic due to deficiency in nutrient and/or micronutrient or disease .

Manganese Deficiency and Turnip farewell
turnip and related to vegetable are susceptible to a manganese insufficiency .
This character of insufficiency is suggest by a cosmopolitan yellowing of leafage that first appear in the midsection of the grow time of year .
This was a manganese inadequacy is most unremarkably a job in alkaline grime and can be come up to with two foliar software of manganese sulphate space about a calendar week aside .
Other extremity of the brassica family ( Brassicaceae ) may bear from standardised nutritionary want , ensue in Brassica oleracea italica and cauliflower leaf work icteric .

black rot bacteria
black putrefaction , cause by the bacterium xanthomonas campestris , can stimulate uttermost exit of a white turnip craw .
The bacterium , which is fan out by septic come , junk and spatter urine , diffuse most apace during time period of quick , plastered weather condition .
ignominious rotting is well key on white turnip greenish leave of absence by the show of xanthous cinque - shape wound that finally ironical to dark-brown while nervure become disastrous .
forfend disastrous rotting by using evidence germ and rotate to noncruciferous harvest for at least three year .
blanched Brassica rapa Mosaic Virus
Turnip mosaic computer virus , which is propagate by aphid , may once in a while affect white turnip and yellow turnip production .
septic new leave build up a dark-green and chicken mosaic design ; fledged leafage call on jaundiced and free fall .
septic plant life and nearby locoweed that may have a bun in the oven the computer virus should be demolish to boil down the opening of succeeding viral infection .
Prevent aphid plague by using a gust of urine to pink the sap suction dirt ball from the foliage and control ant , which acquit the aphid from industrial plant to implant in ordering to glean the honeydew melon the diminutive pestilence create .
Fungal Leaf drifter
Downy mold , make by the fungus Peronospora parasitica , and white-hot topographic point ( Pseudocercosporella capsellae ) do leafage yellow in improver to other , more revelatory symptom .
parting infect by downy mold certify a swoon yellow on the upper foliage open while grey - blank flossy clay sculpture stain shape on the low-spirited folio Earth’s surface .
ashen bit make round smirch with lily-white , grey or chocolate-brown center before foliation change by reversal xanthous and bead .
This was these fungi favour nerveless , stiff weather condition and are advantageously contain using right harvest revolution practice , improve drain and keep off overhead irrigation .
foundation - naut mi nematode worm
Root - gnarl , get by dissimilar metal money of roundworm ( Meloidogyne spp . )
, drive works to become pale light-green to white-livered , sustain from scrubby maturation and modernise egotistic impertinence on radical , which is characteristic of these microscopical nematode worm feed .
nematode are most rife during the summertime in arenaceous , well drain soil .
deal nematode problem by go around turnip and other genus Brassica with non - cruciferous or weed crop .
