Family of the sugar beet. Sow from April to late June in the open ground in the final spot. Thin out by leaving the strongest plants in place. Often two or three are in a clump together; be careful not to pull out all two or three. Sow several times in the April-June period, thus extending the harvest period. Once the tubers rise above the ground, they can be harvested. Don’t let the beets get too big; it won’t improve the taste.
\nWhen the seedlings are +<\/u> 2.5 cm high, thin out to leave one every 10 cm.[\/vc_column_text][\/vc_column][\/vc_row][vc_row equal_height=”yes”][vc_column width=”1\/3″][vc_custom_heading text=”Bugs” font_container=”tag:h4|text_align:center|color:%23ffffff” google_fonts=”font_family:Lato%3A100%2C100italic%2C300%2C300italic%2Cregular%2Citalic%2C700%2C700italic%2C900%2C900italic|font_style:400%20regular%3A400%3Anormal” css=”.vc_custom_1532164328547{background-color: #585858 !important;}”][vc_column_text el_class=”entrytxt”]<\/p>\n

Excessive development of roots; roots appear ‘bearded’ or ‘whiskered’; delayed growth: Beet cyst eelworm (Heterodera schachtii, Heterodera betae).<\/em><\/p>\n

Feeding on the underground parts of seedlings: pygmy mangold beetle<\/a> (Atomaria linearis)<\/em>.<\/p>\n

In spring, the beet leafminer<\/a> lays its eggs on the underside of leaves. Larvae eat the chlorophyll between the veins of the leaves, blisters appear on the leaf, after which the leaf withers. Sometimes the damage is limited to a few leaf mines: Larvae of the Beet Leafminer (Pegomya hyoscyami)<\/em>. Occurs mostly in cool summers.<\/p>\n

Curled leaves; in some places there is an aphid<\/a> of about 2 mm in size: Green peach aphid<\/a> (Myzus persicae)<\/em>.<\/p>\n

Beetroot is not growing, root system shows many small root nodules (galls): northern root-knot nematode<\/a> (Meloidogyne hapla)<\/em>.<\/p>\n

Delayed growth, 2 – 4 mm small nodules at the ends of roots: false Columbia root-knot nematode (Meloidogyne fallax)<\/em>.[\/vc_column_text][\/vc_column][vc_column width=”1\/3″ css=”.vc_custom_1532102790165{background-color: #ffffff !important;}”][vc_custom_heading text=”Fungi & diseases” font_container=”tag:h4|text_align:center|color:%23ffffff” google_fonts=”font_family:Lato%3A100%2C100italic%2C300%2C300italic%2Cregular%2Citalic%2C700%2C700italic%2C900%2C900italic|font_style:400%20regular%3A400%3Anormal” css=”.vc_custom_1537885754502{background-color: #585858 !important;}”][vc_column_text el_class=”entrytxt”]Corky lesions that can develop into warty infestations: common scab<\/a> (Streptomyces scabies)<\/em>.<\/p>\n

Grey spots develop on the leaves, discoloring to brown-black. The spots are bordered by a red band: Cercospora leaf spot<\/a> (Cercospora beticola).<\/em><\/p>\n

Light spots on leaves, later turn brown, holes in leaves: Ramularia leaf<\/wbr> spot (Ramulaira beticola<\/a>)<\/em>.<\/p>\n

Plants wilt, leaves die, and brown or black spots appear on roots: root rot (Rhizoctonia<\/a>)<\/em>.<\/p>\n

A white\/light grey mould of fungus develops on the leaf surface, usually between August and October. Small black dots appear on the infected leaves.
