Pests of kidnapped: classification of them and how we can fight them

Rapesed, with the scientific name of Brassica NapusIt is an annual herbaceous plant, which is established in autumn. It occupies a special place in the global economy, since its seeds are a rich source of vegetable oils, which are used both in nutrition and industry. The culture of rapeseed has a favorable reaction to fertilization, it can be cultivated mechanized, sowing and collection can take place outside the crowded periods and is a good honey and pre -Pianta. But the greatest challenge when it comes to the Colza culture is the parasites of the rapeseed. In today's article we decided to show you what parasites are and how they can be fought.

The main parasites of Colza

The parasites of the kidnapped affect rapeseed crops in the autumn, from the early stages of the vegetation. Although they usually attach the fall, the traces of their attack are also observed in spring. Subsequently we present the parasites of the rapeseed, to find out how to detect their attack and in the end to find out what the main treatments are necessary to fight them are.

The Vespa del Colza

The Vespa of the rapeseed fruits or pierces the rape leaves on the bottom. At the beginning, the perforations are small, but increase over time, they get a round or oval shape and have irregular edges. On the plants attached there are larvae about 17-18 mm long, with the head and the black legs and the gray body.

In order to prevent and combat this parasite, it is recommended to rotate the crops, the correct agrotechnicians, as well as to perform the treatments with specific insecticides.

The fleas of the crucifixes

The larvae of the cruciferous fleas frustrate the petiole of the lower leaves, after which they can reach the upper part of the shoots. The tunnels that these larvae can be filled with water, which can lead to freezing in winter. In addition, these galleries allow the phytopathogens to enter the plant.

In order to prevent and combat this parasite, it is recommended to rotate crops and perform treatments with specific insecticides.

The shiny cockroach

The shiny cockroach fruit the floral gems outside and inside they consume the stamens and the pistil. Its attack causes drying and falling of the gems and the gems that have undergone a small attack produce small, thin and twisted in the upper part. The female of this cockroach fruit the floral bocciolo and lays 1-2 eggs on the stamens. In some cases, in a single floral gem it is located up to 15 eggs, deposited by different females.

As a prevention and control, it is recommended to rotate the crops, the correct agrotechnics, the tightening and destruction of plant residues, as well as the application of the treatments with specific insecticides.

Hairy cockroach

The hairy cockle consumes the floral organs of the rapeseed and, in some cases, the young leaves. Its adult measures 9-12 mm and has a matte black color and its body is covered by a gray flour. It has only one generation per year and winter as an adult in the ground. The females lay the eggs within 4-8 days of the mating. The larvae of this cockroach do not cause damage.

To combat this parasite, it is recommended to apply the treatments with specific insecticides.

The red scarabeo

The red scarabeo irregularly implores the edges of the leaves, so in some cases, after its attack only the ribs remain. It can attack silicve and floral gems. Glass attacks and can develop on spontaneous crucifixes. The female lays 800-900 eggs, at a depth of 3-4 cm in the ground.

As prevention and control measures, it is recommended to treat seeds before sowing, the rotation of crops, the correct agrotechnic, the tightening and the destruction of vegetable debris, as well as the execution of specific insecticides.

Silicven gossip

The adults of this parasite to the small cavities in the stems, peduncles and floral buttons, while the larvae consume the seeds. While developing, a larva consumes 6-9 seeds. Deposit the tip in silicvet in formation. The female of the fruit of Gargoyle in silicel a hole in the silicvic wall and lays an egg in this hole. A female lays 35-50 eggs.

In order to prevent and combat this parasite, it is recommended to collect and destroy plant residues, the rotation of crops, the correct agrotechnics, as well as the application of the treatments with specific insecticides.

The white butterfly of the cabbage

The white butterfly butterfly larvae have a body of 40-50 mm long. In the first phase of development they have a yellow color and, if completely developed, the larvae have a gray color and have longitudinal ribbons. The latest generation attack larvae the part of violence during autumn. The plants attacked by the white butterfly of the cabbage do not develop correctly before the arrival of winter.

As a methods of prevention and control, it is recommended to perform treatments with specific insecticides.

How do Colza's parasites fight?

Subsequently, we present the main recommended insecticides of eliminating rapeseed parasites from culture.

The recommended dose in both cases is 200 l/ha.

The main diseases of Colza

Together with the parasites of rapeseed, there are some diseases that can influence this culture. And we present them below and in the end we offer you some tips on effective treatments to combat these diseases.

White putrefaction

When the rapese is attacked by white putrefaction, the plants are yellow and wans and on the lower side, spots of light, white or light yellow are observed. Over time, these points grow, brown and are covered by a white felt, which represent the fruits of the mushroom. This winters mushroom in the ground in the form of scleriti and in spring a sclerot can produce one or more pharmacists. They have the shape of a cup, a funnel or a disk and the color varies from brown cream.

As a method of prevention and combat, it is recommended to rotate crops, avoid raping on low and humid soils, the treatment of seeds before sowing, showing an optimal depth of 20-25 cm, as well as applying specific fungicides.

mold

The flour involves the appearance of a fine, whitish and felt coating on the surface of the surprise leaves. After a while, this coating develops brown black points, which represent the fruits of the mushroom.

In order to prevent and combat this disease, it is recommended to rotate crops, to avoid the cultivation of rape on low and humid soils, plowing at an optimal depth of 20-25 cm, the treatment of seeds before sowing and applying specific fungicides.

Blight

The disease is observed on silicve, where small, blackish, score or linear are developed. These points extend, therefore they manage to cover large portions. Following a powerful attack, silicvets do not develop and open easily, so the seeds are shaken. On the surface of the spots, a brown black powder develops, made up of conidifori and with mushrooms.

As a methods of prevention and control, it is recommended to rotate crops, avoid rape cultivation on low and humid soils, by warning an optimal depth of 20-25 cm, as well as applying treatments with specific fungicides.

Hernia Radice

When the plants are attacked by the root hernia, the roots appear on their roots and swelling throughout their length. Over time, the roots attached are brown, softens and rot. The root hernia can occur in all stages of vegetation. After the early attack, the plants remain small, the leaves are colorful and red and in ripe plants, the attack causes the coloring of the blue-green leaves.

As a method of prevention and control, it is recommended to rotate crops, avoid rape cultivation for low and humid soils, the use of resistant hybrids and the maintenance of a neutral soil pH.

The hand of the crucifixes

The hand of the crucifixes is a disease frequently encountered in young plants. It manifests itself from the appearance of yellow spots on the leaves and these spots are brown after a while. On the bottom, the stains are covered by a gray white flour, which represents the fruits of the mushroom.

Follicur Follicur only 250 EW It is a product on the basis of 250 grams / liter domestic, being a systemic fungicidal system, which penetrates plants and is distributed inside the tissues, blocking the expansion of the fungal by inhibiting the synthesis process of the ergosterols.

Conclusion

It is important to know what the diseases and parasites of the rapeseed are, in order to adopt the necessary measures to fight them, so that the production is not influenced.
