Is cauliflower prone to black spot? What pesticides work well?

For cauliflower black spot disease, prochloraz manganese salts, pyraclostrobin can be used.

or difenoconazole.

Azoxystrobin plus potassium dibasic phosphate.

Spray, once at intervals of 7 days. Apply 10 square meters of decomposed manure per acre, turn the ground and rake it flat, and then evenly sprinkle 100 kg of ternary compound fertilizer and urea.

30 catties, 4 catties of borax, 1 catty of ammonium molybdate, high ridge planting, so that the fertilizer is basically concentrated on the planting ridge. You can choose a net of cabbage insects, inhibition of Taibao, and imidacloprid.

and other pesticide spray control. Cauliflower is prone to cataplexy, and this disease can only be prevented and controlled, and cataplexy can be used to prevent and control it, and at the same time, the disease seedlings should be pulled out immediately to prevent the spread of the disease. Water the seedlings slowly 7 days after planting.

After that, water and fertilizer should be used together to promote the growth of plants. Generally, top dressing is applied in the flower bulb stage, and 3 15 compound fertilizers of 25 kg can be used, or 15 kg of urea, potassium sulfate.

15 kg. Pay attention to timely prevention and control of pests and diseases.

There are generally two reasons for black spots on cauliflowers, one is because the temperature and light are not suitable, resulting in anthocyanins in cauliflowers.

The color changed from white to yellow, other variegated colors, and even black. The other is caused by pests and diseases. At room temperature, cauliflower can generally be stored for 3 to 5 days, but if it is stored at low temperature in film bags, it has been proved that it can be stored for up to two months, but the temperature and materials of the home storage environment are generally not as accurate as those in the laboratory, and the cauliflower will have a period of transportation and preservation time from picking to sale, so it is best to eat it within 10 days even if it is stored at low temperature.

<>First of all, cut the cauliflower into small florets and blanch them in hot water, then cool them in cold water, and then take out the cauliflower and put it in a fresh-keeping bag, and put it in the refrigerator at about 0 degrees, so that the cauliflower can be stored for about a month. Strengthen field management, rational fertilization, pay attention to the combined application of nitrogen, phosphorus and potassium, and appropriately increase phosphorus and potassium fertilizers to improve plant disease resistance. Leafy vegetables should be harvested early in time to reduce the damage.

Cauliflower is generally more susceptible to black spot disease, and farmers can spray prochloraz manganese salt, pyraclostrobin or difenoconazole, and then spray pesticides every 7 days. Generally, top dressing should be reapplied in the flower bulb stage, and pesticides can be sprayed with a few catties of compound fertilizer or urea and potassium sulfate. Be sure to pay attention to the timely prevention and control of pests and diseases, so that the cauliflower can grow well.

It's particularly easy. Cauliflower has particularly high requirements for the temperature at which it is grown, and there are also high requirements for the choice of pesticides. It is best to use pesticides containing phosphate fertilizers to completely get rid of this disease and increase the yield of cauliflower.

Yes, this vegetable is prone to such a disease, it is very ugly, and it affects the appearance, use chlorothalonil wettable powder This pesticide has the best effect, dilute it to 75%, and you can use it.

It can cause black spot due to insufficient temperature and sunlight, as well as pests and diseases. It can be sprayed with prochloraz manganese salt, pyraclostrobin plus potassium dihydrogen phosphate, or it can be sprayed with cabbage insect once, anti-Taibao, and imidacloprid for spraying control.

First of all, the black rot of cauliflower, this disease is mainly harmful to leaves and blight, the initial stage of the disease will produce black spots, after the expansion will become gray-brown round lesions, long-term unmanaged will lead to its leaves turn yellow and early wither, thereby affecting the emergence rate and growth potential mainly harm the leaves, petioles, peduncles and horns and other parts. Both seedlings and adults can be damaged. Leaf damage,.

At first, it is a nearly circular greenish spot, and after enlargement, it is dark brown in the middle, pale green on the edge, with or without obvious wheel lines. When wet, the surface is densely covered with black mold.

<> hot flashes in summer, high temperature, rain, rhizomes of large vegetables are prone to rot, infectious diseases, and aphids. Jinggang berry can be sprayed to cause infectious diseases, and the ring leaf No. 1 spray is used to kill insects. A few days before sowing vegetables, the land can be sprayed with Jinggang berry to prevent diseases, and there are two main physical control technologies:

One is to use silver-gray film to avoid aphids; The second is to use the yellowing of aphids and use yellow plates to attract aphids. The specific method is to make a 30cm 20cm yellow board from cardboard, apply yellow pigment, and smear waste engine oil (3 5d 1 time).

Yellow-brown lesions appear on diseased leaves at the adult stage. Most of these pathogens do. Immersion from the water hole at the edge of the leaf makes the lesion prone to a V-shape.

The diseased part of the leaf will be twisted to one side, the diseased part will rot, half of the leaf or plant will turn yellow, and some of the outer leaves will dry up or even lose their leaves. The seeds are left on disease-free areas or disease-free plants to prevent the seeds from carrying bacteria. Before sowing, the seeds should be soaked in warm soup or treated with pesticides.

Rational crop rotation with non-cruciferous crops for 1 2 years.

The symptoms and conditions of the disease are basically the same, and the disease mainly harms the leaves, forming large necrotic spots and irregular large macula, and finally leads to the death of the whole leaf dry plant. In order to prevent soft rot of cabbage bacteria, excellent disease-resistant varieties should be selected, and the soil should be deeply turned in advance for sun disinfection, and then sown at the appropriate time, and field management should be strengthened during growth. At the beginning of the disease, spray biomycin wettable powder or agricultural streptomycin sulfate soluble powder.

The prevention measures mainly include, first of all, the seeds should be sterilized and disinfected, and the seeds can be soaked in 200 times of 50% dysenammonium water solution for 15 minutes, and then washed and dried for sowing. During the growth of the plant, it is necessary to top fertilize the water 2 3 times to prevent the premature aging of the plant and enhance its disease resistance.

The seeds are disinfected first, soaked in 55 warm water for 15-20min, and then moved to cold water to cool down and dried before sowing; In rotation with non-cruciferous vegetables, it is also necessary to strengthen the management of the growth period, remove the seriously diseased plants in time and bring them out for proper treatment, and remove the diseased residues in the field in time after harvesting; Watering and fertilization should be appropriate, and damage to plant leaves should be avoided during field farming operations to prevent bacterial infection.

Should be watered in time, in the cauliflower black rot area, spraying agent 50% ammonium dyssen 500 times liquid, agricultural streptomycin, streptomycin sulfate, neophytomycin and other 200 mg kg, the effect is obvious.

Clean the field: After the cauliflower is harvested, remove the residual roots and leaves in time, and take it out of the field to bury or burn: turn the soil deeply, prepare the land and dry the field, and reduce the source of bacteria; Prevention and control of disease-spreading pests: timely control of diamondback moth, cabbage worm, beet armyworm, aphid, ape leaf beetle, ground maggot and other pests to avoid the spread of diseases;

First of all, the black spot of cauliflower, this disease is mainly harmful to leaves and blight, the initial stage of the disease will produce black spots, after the expansion will become gray-brown round spots, long-term unmanaged will lead to its leaves turn yellow and early wither, thus affecting the emergence rate and mainly damage the leaves, petioles, peduncles and horns and other parts. Both seedlings and adults are acceptable. Victimization.

The leaves are damaged, showing nearly circular green spots at first, and after enlargement, they are dark brown in the middle, pale green on the edges, with or without obvious wheel lines. surface when wet. Dense black mold.

<> and larvae at the peak of the use of BT emulsion 200 times, or with 5% anti-emulsifiable liquid, egg hatching peak with 5% Ruijin special suspension per 667 square meters 17ml-34ml, add water 50L-75L, or 5% anti-emulsifiable concentrate 2000 times, or young. The insect is used before the 2nd instar and gathers into a clump on the back of the leaf, secreting yellow honeydew to cause flowers. The leaves of the cabbage turn yellow and eventually fall off.

In addition, aphids are also vectors for the spread of viral diseases, causing plants to yellow, or even die. According to the experience of Qingjiang crane, this disease should be mainly prevented, and once the central disease plant appears in the field, the disease will spread rapidly. , it's hard to parry.

Even if it is continuous. With medication, the condition can only be barely controlled, so prevention in advance is quite serious. Want.

After the white dew, it is the critical period of Chinese cabbage field management, and the precipitation across the country begins to increase, especially after the beginning of autumn this year, the precipitation is generally more than in previous years, and the high temperature and rainy days continue. For a long time, various diseases of Chinese cabbage. The breeding conditions have been created, which is a bacterial dimension for the white and black rot.

Tube disease will occur in the seedling and adult stage of Chinese cabbage, resulting in necrosis and blackening of plant vascular bundles. Infection before the cabbage seeds are unearthed will lead to the failure of seedlings; When the seedlings are damaged, the cotyledons are soaked in water and gradually die, the leaves are sown in a timely manner, the seedlings are watered in a timely manner, the seedlings are squatted reasonably, the diseased plants in the field are pulled out in time and taken out of the field to be buried deeply, and the diseased holes are sprinkled with lime for disinfection.

The nutrient soil for water-upland rotation and seedling cultivation should be made of sterile soil, and it should be dried for more than three weeks before use;

Choose disease-resistant, coated seeds, if not coated, use seed dressing agent or soaking agent;

When planting cauliflower in the early stage, it is necessary to spray an appropriate amount of pesticides to prevent black rot according to the specific situation, so that the occurrence of such situations can be effectively avoided.

1. Choose disease-resistant varieties, such as Zhongqing No. 1, No. 2 and other disease-resistant varieties. 2. Rotate crops with non-cruciferous vegetables for 2 to 3 years. 3. Cauliflower seeds should be sun-dried for 2 3 hours before sowing and then soaked in 50 warm water for 12 hours, or mixed with 50% wettable powder of seed quality Fumei double seed.

4. Before planting, spray the ground with 50% carbendazim wettable powder per mu, and use lime sterilization to adjust the soil pH of the planting field. Ridge cultivation or deep furrow and high furrow cultivation, timely drainage after rain. The furrow is covered with straw.

It's the ** disease caused by HPV, but it's called because it grows more like a cauliflower.

It is more common in sexually active young men and women, among whom there is a history of uncleanness, and most warts are significantly enlarged or increased in a short period of time; If it's pregnant, warts enlarge faster and more noticeably.

At present, it is mainly used with Ran's plant liquid and anti-virus, the former one is found by Nengtian-= cat, and it should be one.

The same thing, cauliflower, cauliflower, cauliflower, cauliflower, just different names Cauliflower is also known as cauliflower, and a certain amount of flavonoids have the function of regulating and preventing high blood pressure and heart disease. At the same time,

The cauliflower bulbs with high commodity value have a dense texture, a white surface, and small flower buds are granular, so everyone likes such flower bulbs in the market and does not worry about sales; And some flower balls are either wrong in color or ugly in appearance, and this kind of bad-looking flower bulb is a deformed inferior flower bulb. Deformity of cauliflower roots. Root deformity is caused by disease, and the affected root becomes swollen after the disease, and a tumor-like thing grows, which is very unsightly.

Taproots, fibrous roots, and lateral roots can all be infected. The temperature requirements for the growth period of the flower bulb are relatively strict, the optimal temperature is 24-18 degrees, below 8 degrees, the flower bulb grows slowly, and 0 degrees is easy to freeze. When it is higher than 24 degrees, the flower bulbs of most varieties are easy to loosen, turn yellow, and deform, and the quality deteriorates.

<> planting cauliflower in winter, due to low temperature and drought, cauliflower is more prone to calcium and boron deficiency, prone to new leaves, leaf tips and leaf margins are dry, leaf stems are cracked, plants are dwarfed, leaf color is light, and flower bulbs appear crystal-like and slowly turn brown to brown and rot. Generally, the open field is heavier than the greenhouse, and the two sides of the greenhouse and the door head are heavier than the middle. Before planting the seedbed, soil treatment agents such as sodium disulfonate or pentachloronitrobenzene should be used for routine disinfection treatment, and ventilation and humidity should be reduced in time after the emergence of seedlings, and the temperature should not exceed 28 degrees during the day to avoid high temperature and high humidity growth environment.

When the humidity is heavy in rainy days, it is easy to cause stem base rot, when encountering such a time, we should pay attention to observation, spray once a few days to prevent, if you do not prevent it, it will be too late to wait for the condition to be obvious.

The cortex is easily peeled away from the stem, revealing the dark xylem inside. The disease occurs only in the roots and rhizomes of the plant and does not progress upward with the vascular bundles. However, root rot spreads quickly, and the incidence increases after watering.

The leaf margins begin to wither and scorch, grow slowly, and the cotyledons die when the roots appear at the cotyledon stage. When the roots rot at a certain leaf stage, the true leaf will wither. The bed temperature is between 12 and 14 degrees for a long time, especially the low temperature at night, which causes the growth point to stop growing, causing the seedlings to die from their roots.

It is very likely that it is a kind of bacteria formed in the soil, and then this disease is produced, so it has a great impact on this vegetable, the first point is that it should be fertilized in time, so that it can be well controlled, the second point should be watered in time, so that the effect is very ideal, and the third point should pay attention to the frequent weeding effect is very ideal.

Bacterial black rot is one of the main diseases of cauliflower, which has a wide range of hosts, and can also harm a variety of cruciferous vegetables such as cabbage, cabbage, rape, mustard greens, and radish. Heavy cropping, frequent rain, partial application of nitrogen fertilizer, and serious insect pests in the field are seriously diseased. In the cauliflower black rot area, the spraying agent is 500 times 500 times of dysenammonium, and 200 mg kg of agricultural streptomycin, streptomycin sulfate, and neophytomycin, etc., with significant effects.

In addition, 50% methyl tobuzin and 50% carbendazim wettable powder also have good control effects. During the growth period of cauliflower plants, top dressing water should be topdressed 2-3 times, which can effectively prevent premature plant aging and enhance the disease resistance of cauliflower.

The reason is the virus damage produced by this plant, so there is such a phenomenon, which is very ugly and ugly. The method is to take care of the roots and leaves carefully when planting, and spray some pesticides.
