What are the different types of cabbage diseases?
all over the world, many diseases attack cabbage. Some, such as black rot, are diseases transmitted by seeds and others are transmitted by soil such as Clubroot. The mold of powder is an example of fungal disease. Gardeners should contact a professional or agricultural agent to learn about the latest methods and prevention. Most of the diseases that attack cabbage will affect other crops of Cole. Other examples of crops Cole are members of the family of mustard, kale and turnip. Many gardeners rotate their crops Cole into areas where these types of plants in the previous vegetation season did not fit, as crop alternation is one of the methods of control to prevent the soil transmitted by cabbage diseases.
Pests generally damage cabbage plants in two ways. First they attack the plant, cause stress to the plant, and secondly, the wounds caused by pests can affect the diseases of plants to enter the plant. Other wounds include cuts of hoes or spade, scratches or damage to animals passing through from from from fromLess and wounds related to the weather.
alternaria brassicae , known as the Alternaria foliage spot, is a disease transmitted by a seed that is not often recorded until the plants are older. Infected plants get stains resembling Eyes Bulls eyes on the oldest leaves. Brown or gray brown spots are usually predominant during magic of warm weather and wet conditions. Generally with disputes dispersed by wind, poor handling of infected plants and using infected seeds distribute this disease.
black rot or xanthomonas campestris is another bacterium transmitted by seed, which is predominant in humid conditions. At the edges of the leaves, stains in the shape of the letter in light brown or yellowish lesions grow and can cause blackened leaf veins. This disease often survives in infected platroska nt for up to a year but does not live long in the soil without plant residues aso host.
The black spot and a spot of dark leaves are two types of alternaria . Like black rot, infected debris abandoned in a growing area can spread diseases. In general, spores can live about 12 weeks after harvest. Plant rotation and careful field cleaning can help control these cabbage diseases.
Although the pool of the parasite is caused by club or Plasmodiophora Brassicae , most people classify it as one of the fungal cabbage. The name comes from club roots that develop in infected plants. Above the ground are yellowed leaves and plants with defects in hot weather. Disputes transmitted by soil transmitted can survive up to 10 years. Agricultural experts suggest alternating plants and treatment of alkaline soils with lime.
fatal disease known as damping or rhizoctonia solani , prevents the germination of young seedlings or causes them to weigh shortly after germination. Symptoms include light brown stems and wilting in young plantss. Typically, planting seeds can be treated and allowed to dry the soil completely between the burn to reduce the chance of closing the disease. Wet weather and high humidity are two conditions that promote damping.
As well as damping, mold fungi thrive in high humidity and wet conditions such as persistent fog, heavy dew and overloading. High winds and splashing rain often spread disputes. Symptoms usually include whitish gray, fluffy spots on the underside of the leaves, black or purple spots on the heads of cabbage or flowers and green yellow to brownish leaf spots that can spread to other plant parts. The Latin name for cabbage -related molds is peronospora Parasitica .
fusarium oxysporum Conglutinans , called Fusarium bath or yellow, is one of the fungal cabbage, and because it shows many characteristics of black rot, IT is often poorly diagnosed. The most visible symptom is usually yellow to greenish yellow leaves that may dropOut. Inflorescence often occurs only on one side of the plant. This fungus can live for years in the soil and rain, or it can spread misconduct. Unlike some other diseases, the infected plant can get rid of the affected leaves and recover enough to create a healthy head of cabbage.
sclerotinia rot or white form, scientifically known as sclerotinia sclerotiorum , affects several plants, but in the cabbage, these fungal diseases attack any part of the plant that touches the infected soil. Symptoms include tan, watery spots that usually develop in cotton, white look. Some people check the Sclerotinia cabbage and let the soil dry completely between watering, removing weeds transmitting diseases and using the appropriate fungicides. Growers should obtain a professional diagnosis before applying fungicides.
One of the soil of Borne cabbage is a wirest from the group of mushrooms rhizoctonia solani anastomosis . Wirest kills seedlings with a belttribe. Infected older plants can produce cabbage or die head before producing any head.
