How to treat dragon fruit canker disease if it is too serious

Is there a **? You can go up to ** to see the situation.

If it is very serious, it is impossible to save it if it is already dead, and the first thing now is to control the development of the disease and treat it as soon as possible.

Scrape off the skin layer of the lesion, apply it with the original solution of "Ulcerative Spirit", the scope of medication is larger than the scope of the lesion, apply 3-4 times, once on the 1st, 3rd and 7th days, and apply again on the 14th day when the disease is serious and there are still water-stained conditions. Looking at the effect, the improvement of the condition turned to prevention.

North China Dragon Fruit Planting Cooperative] both North China Dragon Fruit Seedling Planting Base was established in 2005, is China's earliest greenhouse planting Taiwan red soil dragon fruit varieties planting base, through more than 11 years of development, has become China's dragon fruit planting technology leading dragon fruit seedling typical demonstration base, optimize the cold resistance of dragon fruit varieties, research a set of successful technology of southern fruit and northern species, the base has provided more than 300 dragon fruit planting technology and dragon fruit greenhouse construction technology for all parts of the country, The planting success rate reaches 100%, and the development of one and the success of one. It has developed dragon fruit planting in nearly 20 provinces and cities in China, including Chongqing, Zhejiang Province, Jiangxi Province, Xinjiang, Inner Mongolia and Northeast China in the north, playing a leading role in China's efficient agriculture. It has been reported by many provincial, municipal and county radio stations.

It is completely possible to grow in greenhouses in the north, and it is very successful.

Dragon fruit canker can be prevented and treated with chunleimycin plus zinc thiazole. Use Liangguoan (100 times liquid), garlic oil (1000 times liquid), and wofengsu (600 times liquid) to make a spray Gaohuigao, and spray the whole garden once; Or make blue lead with Liangguoan (100 times liquid), Diliwang (300 times liquid), Wofeng Suqi ruler (600 times liquid) to make a spray, the whole garden spray once.

Dragon fruit canker is a fungal disease caused by Arthrosporium neolugrans, which damages dragon fruit stems and fruits, and young stems are susceptible to infection, forming round white spots at the beginning, gradually turning into brown spots or black canker spots. Dragon fruit canker disease is easy to occur under high temperature and humidity conditions, especially after typhoons, it is more likely to break out in a large area.

Once dragon fruit canker occurs, in the early stage of the disease, spraying broad-spectrum fungicides such as methyl tobuzin, carbendazim, mancozeb and other broad-spectrum fungicides + copper preparations can not achieve the best effect, but can inhibit the spread of dragon fruit canker to a certain extent. In orchards with severe disease, it is basically difficult to use chemical agents to prevent and control the diseased stalks, so the diseased stems should be cut off in time and taken to the outside of the orchard to be burned or buried. Diseased stems should be removed from the garden to avoid infection with other healthy dragon fruits.

Dragon fruit canker disease is prone to outbreak in high temperature and high humidity environment, and chemical control should be based on prevention and control. With the rise of temperature and humidity in spring, it is necessary to treat soft rot, scab and other diseases to prevent compound infection. Recommended formula 1 for chemical control agents

30% pyraclostrobin 1500 times + Pythium 1000 times + 3% mesomycin or streptomycin 1000 times spraying, which can be used safely in all periods. Recipe 2: 50% benzene.

Propylene 2000 times + 40% prochloraz 1500 times + chunleimycin or zhongshengmycin, can not be used in the flowering and young fruit stages.

So far, there is no specific medicine to prevent and treat dragon fruit canker. Once dragon fruit canker occurs, in the early stage of the disease, spraying broad-spectrum fungicides such as methyl tobuzin, carbendazim, mancozeb and other broad-spectrum fungicides + copper preparations can not achieve the best effect, but can inhibit the spread of dragon fruit canker to a certain extent. The precautionary measures for agricultural production are as follows:

1. Choose sandy soil. Before selecting a site for a dragon fruit orchard, you should try to choose sandy soil to keep the soil as little water as possible. Too much moisture in the soil will lead to a decrease in dragon fruit resistance.

2. Choose varieties with higher resistance. There are currently no dragon fruit varieties that are highly resistant to canker disease. Comparatively speaking, white-fleshed dragon fruit is more resistant than red-fleshed dragon fruit, and white-fleshed dragon fruit can be planted in moderation.

However, the quality of red-fleshed dragon fruit is higher and the unit price is also high, and fruit farmers prefer to plant red-fleshed dragon fruit with a lack of footage, which is also one of the reasons for the increasing frequency of dragon fruit canker.

3. Strengthen agricultural prevention and control and apply organic fertilizer. Fertilization should be mainly organic fertilizer, and calcium fertilizer and potassium fertilizer should be applied according to soil fertility conditions, which can increase the thickness of the waxy layer of dragon fruit stalks and improve resistance.

Abstract dragon fruit canker disease, with copper preparations such as spring thunder king copper, or thiomycete copper, or thiasen copper, or quinoline copper, or copper hydroxide, or cuprous oxide, or copper oxychloride, or methyl frost copper, or copper ammonia, or copper pine acid, etc., the prevention and control effect is very good, after the onset of the disease, foliar spraying every 7 10 days, continuous spraying 2 3 times, can control the disease, and make the diseased plants return to normal growth.

What medicine is best used for dragon fruit canker disease**.

Dear, sorry to keep you waiting.

Hello dear, this is what I found, you can take a look.

Dragon fruit canker, with copper preparations such as spring thunder king copper, or thiob copper, or thiasen copper, or quinoline copper, or copper hydroxide, or cuprous oxide, or copper oxychloride, or methyl copper, or copper ammonia, or copper pininate, etc., the prevention and control effect is very good, after the onset of the disease every 7 10 days foliar spraying, continuous spraying 2 3 times, can control the disease, and make the diseased plants return to normal growth.

You can try using these, but if that doesn't work, don't use them.
