Today I would like to share with you a little pesticide tips.
As everybody knows, chemical pesticides to add synergist, but there are some farmers he would say, pesticide use up, sometimes it this effect is not very good, in fact, sometimes pesticide effect is bad, can’t blame pesticide, because now after new pesticide regulations, pesticide control very much, basically there is no have the fake drugs, but there are a lot of all because of improper use.
Today I tell you this is in the pesticide, you put the medicine barrel inside a little vinegar, vinegar has what use?
First, pesticides are generally used when the well water, because the rural tap water is very little, basically with well water, the well water in general, it is alkaline, alkaline add a little vinegar to neutralize the alkaline to it, the water is neutral, the effect of pesticides is the best.
In addition, vinegar contains some acetic acid, amino acid and other things, after these things sprayed on the leaves, the first can regulate the photosynthesis of the leaves, the second can stimulate the growth of the plant leaves, and the other point is that vinegar has a function of sterilization, which is known to everyone. Its effect on crops, although said to be minimal, but also a certain effect.
When planting pesticides can try, add a little vinegar in the medicine barrel do not add too much, add 30 grams, 50 grams can be.
One thing to note, if the alkaline pesticide, we can not add vinegar, such as Bordeaux liquid and so on, these can not add vinegar, if you are interested in, you can try.
Here’s a look at some common uses of vinegar in crops:
1, as leaf fertilizer
Edible vinegar can regulate and promote the growth and development of crops. There are certain differences in foliar spray concentration among different crop types.
Generally, the concentration of vinegar is diluted to 300~500 times (the PH value is close to neutral after dilution). For the varieties with wax powder on the leaves, such as apple leaves with wax powder, the concentration can be appropriately increased.
Periods of common crop use:
Wheat use period: 3 spraying at jointing stage, booting stage and filling stage.
Maize use period: 9 leaf spread, 16 leaf spread and powder after spraying.
Watermelon use period: before flowering, after flowering foliar spray.
Fruit tree use period: young fruit stage, expansion stage, early coloring foliar spray.
2. Vinegar as a herbicide
Different concentrations of vinegar also have a certain killing effect on weeds. Studies have shown that 10%~20% concentration of vinegar solution on annual weeds have 80%~100% killing ability. Vinegar at a concentration of 5% is less effective at killing weeds, and too high a concentration can be risky.
In general, as a herbicide, vinegar can degrade completely and will not pollute the soil. However, the stability of vinegar as a herbicide has certain limitations.
Note: Edible vinegar is generally divided into brewing and blending two processes, brewing vinegar effect will be better than blending effect. Brewed vinegars can be easily distinguished from blended vinegars because they are soft in taste and smell.
