Go for a field where the number of pests and diseases has not increased too much, not a field without pests and diseases.
A nasty pest that eats grown vegetables. It’s really annoying, but unfortunately it’s nearly impossible to get rid of the pests completely. The fertility and vitality of insects are very strong, the harder you try to get rid of them.
If you sell vegetables as a product you will be worried about eating a little worm, but if you are using it for your home garden, it is important that you don’t mind eating a little worm. One way is to deal with it by not targeting a completely disease-free field, but by not increasing the numbers by too much.
In doing so, it is necessary to know the role and nature of insects and find out the cause of the increase in pests and diseases.
What are the bugs?
Although it is often considered an unpleasant existence, it plays an irreplaceable role in the enrichment of the earth. Here, I would like to introduce three roles that I consider important, especially in terms of field development.
Beautiful flowers bloom on the trees to attract insects like bees. I gave them pollen to help me leave the children. It seems that some mosquitoes and flies also carry pollen. Likewise for vegetables, especially vegetables such as strawberries and pumpkins, when polluted by insects, many fruits will be produced.
With the cooperation of insects and microorganisms, we decompose dead leaves and dead organisms into small pieces. And by repeating the cycle of recombination as new soil, soil becomes richer.
In the natural world, there is always a balancing act. It automatically balances certain nutrients, microorganisms, plants, insects, etc. so that they do not increase or decrease too much. Field insects occur there on the same principle, and when viewed from the wild, they move around based on this function.
I have introduced the above three roles but in the end it can be said that “insects are trying to enrich the ecosystem”.
Are the pests also trying to enrich the field?
I explained that the insect is trying to enrich the ecosystem and the soil, but the pests in the field really have the same purpose.
For example, if you focus on feeding “plants just called vegetables” as “fertilizer” on the field, this is a very unbalanced state from the point of view of the whole soil. That’s where the natural balance function works. In other words, pests and diseases come to eat vegetables that have not been supplemented with nutrients and the numbers are increased. And the insect drops manure in the field and tries to spread nutrients throughout the soil.
After a while, the increased pests will be eaten by the natural enemies. During this time, when the number of natural enemies increases, the number of natural pests will decrease. In this way, when viewed as a whole, nature is working to disperse nutrients throughout the soil and enrich the soil and entire ecosystems.
How to reduce the damage of pests and diseases thoroughly
The purpose of the insect and the natural world is to “enrich the ecosystem (soil)”, and the human purpose is to “harvest vegetables”. As long as there is this void, damage caused by pests and diseases cannot be basically addressed, and symptomatic treatment will be pursued.
So why not pair the insect’s purpose with the human purpose?
If you change your perspective, you will see a fundamental solution. Specifically, the following four methods can be considered.
1) Increase soil fertility
Even if it’s a pest problem, basically tillage is crucial. If there is an imbalance of nutrients and microorganisms in the soil, the risk of insects coming as a coordinator increases, so there is a need to improve soil strength and ‘soil viability’ while balancing it. have.
By taking the role the bugs are trying to play here first, you can minimize the need for them to come. For points for improving soil fertility see the article “No fertilization required! Three points to improve soil fertility”, and for specific tillage methods, see the article “Easy for beginners. get started! Compost the soil “. ..
Note, however, that a large number of pests can be present during the fertility increase of this soil. Where there is an imbalance, the more powerful the work to restore it. It’s important to look at the long term.
2) Do not destroy harmful insects
No matter how much you hate insects, if you destroy them, their natural enemies will decrease because they will run out of food. As a result, it creates an environment where the pest is likely to increase again. Close your eyes so you can eat a little.
3) Prepare the surroundings
In the first place, if the whole field environment is not good for vegetables and the environment is preferred by pests and diseases, vegetables will be easily damaged by pests and diseases. For example, in the case of a field with a lot of named whales, even if you keep getting rid of these whales, if the place is in a humid environment, it will come again. Most vegetables prefer sunny, well-ventilated, well-drained places and are relatively well suited to such environmental insects.
4) Reduce the use of highly effective fertilizers and pesticides
The faster fertilizers and pesticides, the greater the risk of ecosystem and nutrient imbalances. Please be careful not to depend too much on these documents.
How about the city or the orchard?
If you are in a man-made environment, such as in a city or on a plantation, it can be a little tricky as there are quite a few limitations to essentially enrich the ecosystem. Prevent insect outbreaks as much as possible by spreading insect repellent nets to prevent insect entry by improving sunlight and ventilation.
◆ Notice next week
Either way, it takes time, and pests can inevitably emerge as nature regains balance. Next time I will introduce ways to prevent damage from pests and diseases without significantly affecting the balance of soil and ecosystems at those times. expected!
