Horseradish diseases: how to deal with diseases and pests
Content:
A huge number of old, Russian sayings are associated with this vegetable. These sayings always emphasize the sharp taste and aroma of this culture. But horseradish is very beneficial to human health and has antiseptic properties. Most often, horseradish is used in home preservation. And it is extremely unpleasant when this culture is affected by this or that disease or pest. Today I will tell you about ways to combat and prevent horseradish disease and harmful insects.
Horseradish diseases: we remove pests
Horseradish is often grown on personal plots, it grows without any problems and does not leave any trouble for summer residents. This culture is not extremely whimsical, grows in any soil, tolerates almost all types of fertilizers and is not picky about watering. But it is useful not only for people, but also for insect pests. Consider the most important enemies of horseradish.
Horseradish diseases: Babanukha
Loves horseradish leaves. Small green beetles that grow up to 3 cm in length. The babanukha larva is capable of gnawing a huge amount of green foliage. Babanukha is activated in early June, when it wakes up after wintering. From the laid clutches, new offspring will appear only at the end of August. The larva lives for three weeks, then pupates and falls into hibernation until the next season. If you see horseradish leaves start to look like a sieve, remove them immediately. If the horseradish is very badly affected, it is necessary to dig up the soil. To scare off a babanukha, you can use a mixture of ash, mustard and red ground pepper. Sprinkle the soil under the horseradish bushes with this cocktail. I also recommend sprinkling horseradish with yarrow or wormwood infusion. Babanukha hibernates in plant debris, so carefully remove it from your soda plot this fall.
We bring out a wavy flea
A very small beetle that is difficult to see with the naked eye. It is black in color with yellow stripes. The flea eats horseradish leaves. This pest wakes up as soon as the snow melts and immediately starts looking for food. The flea lays clutches on the soil surface. In order to protect your site from the invasion of this pest, remove all plant debris and foliage in the fall. Dig up the soil well, and loosen the horseradish beds, this must be done quite deeply. Weeds are removed in a timely manner, since until horseradish shoots appear, the wavy flea feeds on weeds. If the wavy flea has spread throughout the entire area, it is best to use special preparations. But if its number is not large, you can do with folk methods. Sprinkle over the beds with a mixture of ash, red pepper and mustard. You can also spray the bushes with a 1% solution of vinegar essence or a decoction of tansy.
Cabbage moth
Moth larvae are also capable of harming horseradish. Not a large butterfly, gray-brown. The larvae spend the winter in the soil, wake up only in June and immediately go in search of food. The female lays eggs on the back of the leaf. After ten, offspring are hatched, which have a simply brutal appetite. It harms horseradish for about a month, then pupates and hides in the soil for wintering. Prevention of the appearance of these pests is absolutely the same as for previous pests. Planting horseradish should be done in early spring before the appearance of the cabbage moth.If the area is almost completely affected, use special drugs.
We poison the cabbage bug
If the leaves of horseradish began to become covered with spots and gradually turn yellow, then a cabbage bug has appeared on your site. The pest is quite large and can grow up to 10 cm in length. Females lay their clumps on the inside of the leaves. The pest begins an active lifestyle as soon as a constant positive air temperature is established. Larvae and adult bugs eat the leaves and suck nutritious juices out of them. They overwinter in foliage or plant debris. In order to prevent the pest from appearing on your site, carefully dig up the soil and remove plant debris. If the bug nevertheless appeared on the Greek with horseradish, you can scare it off with wood ash, a mixture of sand and naphthalene, tobacco dust or soapy water.
Treat horseradish disease
In addition to pests, horseradish is very often attacked by diseases, fungi and all possible viruses, we will now consider the most dangerous of them.
Horseradish diseases: Ascochitis

The first sign that horseradish is infected with this horseradish disease are brown spots on the foliage. The fungus forms spores in the affected areas and hibernates there. Over time, the leaves turn yellow and die off, then the root crop gradually dies. Waterlogged soil and fungus-infected seeds contribute to the development of this disease. To avoid the appearance of the disease, carefully follow agricultural techniques. If the plant is infected, remove the diseased leaves and treat the bushes with Bordeaux liquid. I carry out the processing once a week, until the fungus disappears completely.
We treat horseradish disease white rot
It is a horseradish disease that appears on leaves and roots. The fungus is a white bloom with black specks. The plant withers and dies very quickly. This fungus is very active during the rainy season. In order to avoid contamination, follow the rules: - do not overmoisten the soil; - keep a distance when planting horseradish; - feed with complex fertilizers; - remove weeds in a timely manner; - buy seeds in trusted places; - sprinkle acidic soils with lime.
Horseradish diseases: leucorrhoea

If the leaves and stems are covered with a white, mucus-like coating, the horseradish is contaminated with the linen. This fungus grows well in plant debris, where it hibernates. If horseradish leucorrhoea spreads almost throughout the plant, it can no longer be saved. If the plant is partially infected, treat it with a solution of copper sulfate. If the fungus has infected the entire plant bed, it is best to eliminate it.
Treatment of verticillium wilt
A fungus that enters the vascular system of plants. The leaves from this horseradish disease begin to wither, and the roots decompose, the plant dies. the fungus hibernates in the soil, it can live for several years. If horseradish is infected, we uproot diseased plants. We dig the earth very deeply, sprinkle it with ash or lime. We carefully remove plant waste.
Downy mildew

This horseradish disease affects the leaves. Horseradish leaves begin to form a white, flour-like coating and yellow spots. Over time, the leaves turn brown and wither. The root crop becomes very loose and small. Prevention against this disease is seed treatment before planting. If the disease still manifests itself, treat the bushes with a solution of copper sulfate. Simple rules will help to significantly reduce the risk of this fungus: - observe the crop rotation; - regularly get rid of weeds; - fertilize the soil; - pour the horseradish with cool water; - dig up the soil in the fall; - Thoroughly remove plant residues.
All these measures will allow you to avoid the need to treat horseradish with chemicals and avoid horseradish diseases.
