How to prevent and control bacterial wilt of cherry tomatoes, and can cherry tomatoes be saved if th

Tomato bacterial wilt is a bacterial disease. It is recommended to irrigate the roots with copper preparations such as copper or quinoline copper or thiaseen copper, and at the same time spray bacterial pesticides such as mesbiomycin or streptomycin or zinc thiazole or chunleimycin and so on plus foliar fertilizer. (Severe vine symptoms can also be combined with high concentrations of the above products to apply vine disease or injection).

This disease is mainly controlled by root irrigation, supplemented by foliar spray control, and the ability of crops to transmit water and fertilizer is poor after the disease, and the leaves are sprayed with mixed foliar fertilizer to supplement energy.

Serious uprooting! Then the original soil was disinfected with the above-mentioned pesticides.

It is best to prevent it early, and it is best to use copper preparations such as copper ammonia on the day of planting to prevent it.

Summary. Yes, but cherry tomatoes wilt should still be prevented, you can choose hormone-free water-soluble fertilizer, water-soluble fertilizer with good disease resistance to fertilize, and the soil can not be forgotten, flush with 2 billion microbial agents to improve. When cherry tomatoes are planted, the seedlings are generally older, and they are generally no longer watered during the period from the time the seedlings are watered slowly to the first ear of fruit sitting.

In summer and autumn, the seedling age of cherry tomatoes is small, and after slowing down the seedlings, it is necessary to promote the rapid growth of seedlings, timely watering, and pay attention to cultivation after watering. Flowering period of water control squatting seedlings, flowering rarely watered, unless the drought is serious, this period is mainly to keep the soil loose, the surface dry, promote strong seedlings, to ensure that the root system expands downward, for the future plant vigorous growth, lay a good foundation. When the first ear of fruit sits 2-3, the fruit should be watered in time to promote the fruit.

Hello dear dear, can cherry tomatoes be infected with bacterial wilt during the maintenance of cherry tomatoes, but bacterial wilt can also be ** if it is properly maintained. The formula of the celebration of bacterial wilt is to mix the bacterial wilt of wilt and garlic oil and make a spray and agent to apply to the plant, which can be effective for the bacterial wilt of the cherry tomatoes.

The sooner it is treated, the better, for the bacterial wilt of cherry tomatoes, the symptoms of vascular discoloration are typical of the disease. If the situation of two celery days can still be treated, it is recommended that you spray three times in a row, once every three days, without worrying about the harm of the drug, and the traditional Chinese medicine is non-toxic.

Summary. Hello dear, the sooner it is cured, the better, for bacterial wilt, vascular discoloration when the disease is typical of the symptoms. If this situation can still be treated for two days, it is recommended that you spray R. solanacearum three times in a row, once every three days, without worrying about the harm of the drug, and the traditional Chinese medicine is non-toxic.

Hello dear, the sooner the treatment is better, the hall rolls in bacterial wilt, vascular discoloration when the typical symptoms of the disease. If such a situation can still be treated for two days, it is recommended that you spray R. solanacearum three times in a row, and pretend to be dry once in three days, without worrying about the damage of the spike, and the traditional Chinese medicine is non-toxic.

The prevention and control method of bacterial wilt of cherry tomatoes 1, the introduction of grafted seedlings and the introduction of disease-resistant and withered grafted seedlings is one of the effective measures to prevent bacterial wilt, and it is best to rotate in paddy fields, which can be disturbed and rotated with cruciferous or grassy crops in China Agriculture and Forestry Network for more than 4 years.

2. 3-5 days before transplanting, seedlings can be combined with extra-root fertilization to do a good job in pest control, and 75% chlorothalonil wettable powder can be sprayed 600-800 times + 50% carbendazim wettable powder 500-600 times + 10% imidaclophant 1000 times liquid for control.

3. Strengthen field management (1) When transplanting, the amount of cracking and slipping is less and the roots are damaged, and the tomato can be cultivated in the early stage of growth. (2) Apply sufficient base fertilizer, apply fully decomposed organic fertilizer, and increase phosphorus and potassium fertilizer to improve the disease resistance of plants. (3) Deep furrow and high furrow planting, reasonable irrigation, to avoid water accumulation in the field to hurt the roots and uneven drying and wetting.

4) Remove the disease residues in the field in time to avoid the greater spread of pathogenic bacteria.

4. After the disease is found in the anti-grinding draft of the drug, spray blind + irrigate with 90-150 times of R. solanacearum Rick + garlic oil 1000-1500 times, and use it 2-3 times in a row, with an interval of 2-3 days.

Summary. Hello dear, I'm glad to answer for you, cherry tomatoes have bacterial wilt and can be saved.

Hello dear, I'm glad to answer for you, cherry tomatoes have bacterial wilt and can be saved.

**The method is to use R. solanacearum and garlic oil to mix, pour in a spray bottle to spray the plant, or you can use the mixed Lingsou agent to irrigate the roots of the plant. It is necessary to irrigate the roots 2 to 3 times in a row, and then every 2-3 days. Spray once a day with stuffy spraying, and spray the plants for three days in a row.

In this way, it can effectively alleviate the bacterial wilt infected with cherry tomatoes.

When talking about the tomb, it is necessary to pay attention to the dosage of the agent for bacterial wilt, if it is spraying, it should be sprayed once a day, and the ruler is selected to be carried out on a sunny day, so that it can be more effective. The agent should be used to irrigate the roots every 2-3 days, and then irrigate about 2 or 3 times in a row. At the same time, the field management should be done in a timely manner.

In the early stage of bacterial wilt, copper preparations (copper ammonia, copper succinate fertilizer, copper hydroxide, etc.) can be used for root irrigation and control, and the prevention and control effect is good. Chunleimycin, thiobactyl copper, thiazole zinc and other agents can also be used for spray prevention and control, once every 7 to 10 days, and sprayed 2 to 3 times according to the improvement of the condition.

1. According to the planting experience, according to local conditions, choose more disease-resistant varieties. 2. Avoid continuous cropping of heavy cropping and rotate with other vegetables. Use the substrate of the hole tray to raise seedlings, or use onions, garlic or grain field soil as the culture soil for seedling, and plant with medicine before planting.

3. Strengthen water and fertilizer management, apply enough organic fertilizer and formula fertilizer to improve plant stress resistance. Implement high ridge mulching cultivation, and avoid irrigation on cloudy days and flood irrigation. 4. Reasonable dense planting according to the characteristics of different varieties.

5. Prune in time, beat branches and tie vines, remove the old leaves of the lower part of the plant, and improve the ventilation and light transmission conditions between the plant rows. 6. Pharmaceutical prevention and control. Before planting, tomato seedlings were sprayed with 1200 times of DuPont Easy Water Dispersible Granules to prevent diseases and planted with medicine; After planting seedlings, foliar spraying of 1200 times of DuPont Easy Water Dispersible Granules or 75% chlorothalonil wettable powder 600 times for prevention, 7 10 days 1 time.

When the central diseased plant was found, the diseased leaves were removed and diluted into a paste with 68% gold redomir to smear the diseased spots on the stem. When the number of diseased plants reaches 1%, comprehensive control will be carried out.

1. Improper watering.

Improper watering is one of the culprits that cause the leaves of cherry tomatoes to wilt, although the plant can not be left with stagnant water when watering, but also watered enough to ensure that the soil can be in a slightly moist state for a long time, and in times of drought to replenish water in time, otherwise its leaves will wilt because of lack of water.

Second, the light is too strong.

Excessive light will also make the leaves of cherry tomatoes wilt, this plant needs enough light under normal circumstances to facilitate its photosynthesis and ensure the growth and development of the plant, but at the same time, it also needs to be properly shaded when the sun is too strong, otherwise the leaves of the plant will be seriously dehydrated, and it will wilt because of burns.

3. Soil discomfort.

Soil discomfort is also a cause of wilting leaves of cherry tomatoes. Cherry tomatoes are suitable for living in soil with loose and porous structure, good ventilation and drainage ability and a certain basic fertility, if the soil is overly salinized and compacted, the plant will be unable to absorb water from the roots, and the leaves will wilt.

Fourth, pest and disease infestation.

After the plant is infected with pests and diseases, the leaves will also dry and wilt, because after the fungus invades the cherry tomatoes, it will affect its water pipeline, or the pests directly eat the plant and destroy its nutrient system, so that the leaves will dry up and wilt because they cannot get water and nutrient supply. It can be sprayed with pica foliar fertilizer in combination with pesticides for control.

Summary. The cherry tomato has this bacterial wilt, can it be controlled with these two medicines?

The cherry tomato has this bacterial wilt, can it be controlled with these two medicines? Yes, kiss.

Please see the following figure for the prevention and control methods.

At the beginning of bacterial wilt in nightshade crops, the aboveground manifestations are wilting at noon, and slightly recovering in the morning and evening, and because the time from the onset to wilting of bacterial wilt is relatively fast (about a week, from the onset of the disease to the death of the general will not appear yellow leaves, fallen leaves, and the leaves are still green when they die, so it is called bacterial wilt).

When the plant has the initial stage of disease, use 77% copper hydroxide wettable powder 500 times, or 14% copper ammonia aqueous solution 300 times, and 72% agricultural streptomycin soluble powder 4000 times, every 5-7 days to the plant alternately drench roots and spray stems and leaves, each plant is irrigated with 3 times of medicine. For the dead plants, it is recommended to dig them in time and burn them in a concentrated manner outside the field, and sprinkle lime powder on the planting holes for disinfection.
