Old farmer @ Trinh Van Ba doesn’t go to the garden because it rains, he goes to the net…
Three causes of cotton loss, fruit loss Pepper causes great damage – preventive measures.
Hello Giatieu.com community. Hello friends !
The causes of cotton loss and fruit drop in pepper plants are many. If the cause is not properly identified, there is no right prevention, no reasonable treatment. Careless treatment will do single damage and double damage. Because there is a lot of material on this topic, in the framework of this article, I only mention 3 causes of the heaviest damage that I and many pepper growers have ever encountered for community reference. .
1.The wind blows
This type of wind usually appears around the end of March to June of the lunar calendar every year.
Characteristics : very dry ; Wherever the wind goes, the humidity of the air there will be extremely low. Therefore, any pepper garden that is in the period of flowering and pollinating encounters this wind is considered a great disaster.
When blooming, the pilot needs a lot of moisture to release the anthers; If the anther is too dry, it will not pop out and the pollination process will be very difficult. As a result, many unseeded flowers will fall off massively; the rest will be jagged. heavy rake. The wind is very easy to identify; That is, when we go to the garden early in the morning, we don’t see the “wet dew” leaves as we often see in the early morning. This wind only harms in the period of pepper bloom and pollination. In this case, the treatment measures become useless.
Precautions :
– Actively let pepper bloom early, with the following conditions: Actively watering, enough time to cut off water.
– Spray fertilizers with growth regulators, rich in microelements. My experience is that calcium – boron is indispensable when pepper is in the stimulant stage. Note that implementation 4 is correct.
Maintain high humidity for the entire surface of the garden soil.
– Do not prune the branches of the live pillar at this time.
– The garden has fresh cover crops such as wild peanuts or other useful vegetables, the better.
2. Use copper-based pesticides when pepper is bearing cotton and bearing fruit
It is very common for co-preventative drugs to treat many types of harmful fungi on plants. But with pepper that can only be used at certain stages, such as washing the garden after harvesting, it will have a good effect. On the contrary, using copper-based drugs on pepper plants at other times will cause harm, especially cotton loss and fruit drop.
The degree of damage depends on the time of spraying, dosage, weather, … but there are different levels of damage. The heaviest is spraying copper base when pepper is bearing flowers or young fruit. After a few weeks, the pepper spray will fall off massively. Because it falls off after spraying for a long time, we don’t know the main cause and the end is aimless treatment, single harm and double harm. And yet, after massive shedding, it will continue to fall again and again until there is nothing left to shed.
The number of fruits left on the tree after the first fall is very slow, large and small fruits are irregular. Gardeners are impatient – want to increase fruit size quickly, so increase fertilization. The more you fertilize and the more you spray the nutrients, the stronger the fruit will fall. At the time of harvest, there will not be much left. The fruit is small, ugly, many fruits have no skull… that’s a bitter ending.
The precaution is simple: Never use a copper-based spray for pepper while the flowers are bearing fruit.
3.Heat Shock
Most of you will find it strange when reading these two words with pepper plants. Yes, I have to use these 2 words to reflect properly.
During the period of bearing fruit and pepper, it is necessary to have enough water to dissolve minerals of all kinds to raise fruit trees and regulate heat for plants. To meet that need, we must regularly water.
For many reasons, most of us are using irrigation. There is nothing worth mentioning if we know the needs of plants to water at the right time, in the right way and in the right place.
When the weather is hot, the outdoor temperature is high, which will make the plants lose water quickly. In the afternoon and early afternoon, the temperature can reach 39-40 degrees Celsius or more, the pepper will drop its leaves. Too bad, we water the whole pillar to “cool”. A few days later, the pepper posts are watered now, this way, the fruit will fall off.
Like some other causes of fall, when affected pepper plants will not fall immediately, it will take a certain time for the flowers to leave the branch. And then, due to unknown reasons, it should be treated “inadvertently” with single damage and double damage.
Why ? Simply pepper plants suffer from heat shock; Simple physics lesson at the elementary level: “…. matter expands when hot, shrinks when cold…” In this case, the pepper plant is hot, we water it to cool it down, causing the branches to shrink and the cotton to shrink. about mind ; The loose layer between the flower and the branch is considered “done”, waiting for the day to fall.
Precautions : very simple – do not water when the sun is too hot.
Dear community, friends!
In the content of this article, I mentioned 3 causes of cotton loss, fruit drop, and only mentioned preventive measures without mentioning treatment? Because there is currently no cure or treatment, if you suffer from severe consequences.
A little experience to share with the community and your reference.
Wish you good health, good pepper, good season, good price..!
