Rhubarb (lat. Rheum) is a genus of perennial herbaceous plants belonging to the Buckwheat family. Rhubarb is most widespread in Europe and the United States, although it grows in Asia as well. The origins of rhubarb are rather confusing. This culture is mentioned in the writings of Pedanius Dioscorides, who lived in the first century AD. In the XI-XII centuries, rhubarb began to arrive in Europe from Asia through Persia. Marco Polo, who visited the Tangut kingdom, claimed that rhubarb root was grown and harvested there in large quantities.

Culture pests

Often, gardeners are faced with the need to control pests living in sorrel. Many do not believe that this culture is attacked by insects, because its foliage is acidic enough for them. But it is not so. Having survived frosts, a perennial vegetable can disappear in the middle of summer, seemingly without sharp reasons.

Sorrel can suddenly dry up precisely because of the attack of insects, which not only feed on the foliage and root system, but also additionally spread sores. It is considered correct to grow a crop on one site for no more than 4 years. To a greater extent, this is one of the ways to save a herbaceous plant from parasitic forms. Timely harvesting of weeds and plant debris increases the chance to save the harvest. Although this does not give 100% guarantees.

It is known that today there are many chemical-based drugs that help fight parasites, but such methods make plants unusable. This means that such treatments must be carried out outside the harvest season. Sorrel is attacked by the following pests:

  1. Leaf beetle... The first sign of the presence of an insect is leaves with holes. The pest hibernates in the guise of a beetle, which actively eats greens. On the back of the leaves, the parasite usually lays eggs. In one season, several parasitic generations grow up, feeding on the same plant. To combat beetles, it is customary to use an infusion of pyrethrum, which is sprayed on the crop.
  2. Aphid... Often insects are transplanted from other plants growing above the sorrel. First of all, bugs eat the young foliage of fruit trees, and then switch to vegetable crops. Together with the pest, a spider mite can also wander, the appearance of which is evidenced by the presence of a web. To combat parasites, folk methods are used: they attract insects that feed on aphids, plant spices and spray them with infusions of garlic, burdock or ash
  3. Sawfly - a pest with wings is able to fly from other areas. It is capable of giving several generations per season. The presence of weeds and plant debris makes the site attractive to the sorrel sawfly. Effective processing with infusions of chamomile pharmacy
  4. Winter scoop... A butterfly causing great damage to the crop. The caterpillars of such a parasite completely eat up the foliage of vegetables, the closer the winter, the lower the scoops fall. The pest hibernates in the remains of plants and directly in the ground. Digging deep into the soil will help kill future parasites. Spraying with burdock infusion is considered effective in the fight against winter scoops
  5. bug - clicker (wireworm). The insect lives in the ground. Oviposition begins with the arrival of summer. For several years, the larva grows, all this time feeding on the root system of the plants. The acidic soil and the presence of grass are ideal conditions for wireworms to live. Preventive measures include digging up the earth to a depth of 20 cm, frequent replanting of sorrel and cleanliness on the site.

Like any vegetable crop, sorrel is susceptible to pest attacks. By not creating ideal conditions for the reproduction of parasites, you can prevent crop loss. It is worthwhile to devote time to proper crop care and preventive measures so that the plant pleases with good yields.
