There are actually two types of vegetable diseases! Response and prevention points by type

The cause of the disease in the first place?

When something goes wrong with growing vegetables, I first think about the role and significance of the problem in nature. Everything in nature has meaning, and everything plays a role towards the common goal of “enriching the ecosystem”. By thinking from there, we can grasp the essence of the problem and approach the radical solution.

It was the same even when it seemed as troublesome as an illness. Disease has a role of “purifying and excreting” in the natural world, I think. In other words, if there is any backlog like nutrients, water, microorganisms will be destroyed and dispersed to create the flow again, it means that disease exists in this world. . So I will think about how to deal with it while keeping in mind that it will not cause stagnation in the field, improve metabolism and induce circulation.

There are two main causes of disease in vegetables

Next, we will learn about the diseases on vegetables. That being said, there are many names for vegetable diseases that I cannot remember. However, there are only two types of causes, “viral / bacterial” and “moldy”. If you know the two types at the moment, you will naturally be able to know how to cope and prevent them.

Diseases caused by viruses and bacteria

There are many types of diseases caused by viral and bacterial infections such as yellow leaf disease, papillitis, elephant mosaic disease, wilt disease and molluscum disease. Have. Both bacteria and viruses cannot enter vegetables on their own, so sap-sucking insects such as turtles and abram mediate disease. Also, if there is an injury, something rain or wind could enter.

Disease caused by mold

Diseases caused by mold include udon, gray mold, and sticky diseases. Unlike viruses and bacteria, the mold itself is found naturally in the soil and is an essential microorganism. However, if the rate increases too much, it will easily cause disease.

How to prevent disease?

Completely preventing vegetable disease will be difficult unless grown in a place such as a sterile room. However, the risk of developing the disease can be reduced by combining three methods: (1) preventing pathogens from attaching, (2) increasing the vegetable’s resistance and (3) creating an environment for pathogens to stay away. increase. Ability.

① Prevent germs from attaching

Viruses and bacteria are usually transmitted by insects, so taking care of them can reduce the risk of disease. Special attention should be paid when the number of insects that absorb the sap of trees such as stink bugs, turtles, and lizards increases. Use insect repellent nets or destroy them to prevent them from overgrowing. See the following articles for details.

Mold cannot be prevented because it is inherently in the field, but if you bring immature compost that smells like ammonia or mildew in the field, it will increase temporarily. have. Do not use immature compost as much as possible, or do not plant or sow immediately after use, leave on for 3-4 weeks and wait for it to settle.

In addition, mold in the soil can attach to vegetables caused by mud splashes in rain or watering. Use vinyl or fallen leaves as much as possible for covering.

Coating with fallen leaves or vinyl will prevent sludge from splashing in and prevent disease.

② Increases resistance to vegetables

When choosing seeds and seedlings, you have the right to choose varieties that are resistant to the disease. Some of them are made by improving seed or grafting to prevent them from getting sick, so check for the “○○ resistance” symbol written on the seed bag or ask the seed store. .. In addition, when buying seedlings, choose strong, thick and short stems. Many perennial seedlings will be poor and susceptible to disease.

Even if the seedling is strong, if there are injuries, it can allow entry from there. When planting or pruning, take care not to damage them more than necessary. Especially when it rains, the wound doesn’t dry easily and tends to stay open, so when it rains, avoid pruning as much as possible. Even if you water the leaves, if you apply them to the leaves, the leaves will spoil and possibly invade so don’t apply as much as possible.

③ Create an environment for pathogens not to proliferate

In particular, mold is natural in the field, so it is necessary to create an environment so that mold does not increase too much. To do this, simply improve sunlight and ventilation of the field and improve drainage. If this is not done, the mold bacteria will multiply again no matter how hard you try to sterilize.
In environments such as patios where the amount of sunlight and ventilation is limited, place the pot as high as possible, thin it and prune as soon as possible to improve ventilation. In the case of fields, the ridges are raised to ensure ventilation.

The preparation of the microbiological environment in the soil is just as important as the human gut microbiota. A good balance with anti-mold microorganisms reduces the risk of mold growth immediately. Minimize the use of chemical fertilizers, pesticides and herbicides to keep the balance of bacteria in the soil as much as possible. When using organic manure such as cow manure, use ripe manure to prevent the proliferation of bacteria. We recommend weed-based soil preparation and composting of weeds and fallen leaves, which makes it easier to balance bacteria.

In addition, pieces of bamboo, wooden poles, farm bills are also plugged into the ground where it is very susceptible to mold. Keep as close to the vegetables as possible, or grill the surface to prevent mold from spreading to the vegetables.

What if I get sick?

If there are any infected leaves or strains, remove them to prevent the spread of the disease. If it is caused by viruses or bacteria, it cannot be treated, but if it is caused by mold, it can be cured if handled early. The simplest and easiest way is to dilute baking soda 300 to 500 times and spray. It’s not always completely cured, but it’s reversible at an early stage.

However, in the beginning it will be difficult to determine what it is, even the disease in the first place. One way is to take a picture of the part that appears to be sick and see how it progresses, rather than rushing and playing with it first. We also recommend using it as an opportunity to learn, such as asking someone for details or searching online. Sickness is an inherent part of the organism, so don’t be in a hurry to learn it little by little.
