The weather is hot, what points should be paid attention to when applying pesticide to fruit trees?

It's dog days, and it's very hot and dry. For orchard managers, hot weather is also conducive to the breeding of various weeds and pests, and it is necessary to do a good job of prevention and control in time.

Then it is inevitable to spray chemicals on the fruit trees at this time to prevent them from drying up. However, under high temperature, spraying chemicals on fruit trees is limited by one condition, and improper treatment may be counterproductive.

So what points should fruit trees pay attention to in high temperature weather? Let's get to know each other.

1, the pesticide concentration should not be too high.

In hot weather, it is suggested that the concentration of pesticides should not be too high, because high temperature is easy to evaporate the water in the liquid medicine, and the water molecules in the liquid medicine will quickly spread and disperse in the air, which is basically equivalent to improving the concentration of pesticides.

If the concentration of the drug itself is very high, it is easy to cause phytotoxicity to fruit trees, so farmers should strictly abide by the drug standards when it is hot in summer.

2. Don't spray at high temperature at noon.

At noon in summer, the temperature is the highest in a day. Some farmers are eager for success and like to fight pesticides at high temperature at noon, thinking that the efficacy will soon come into play.

In fact, this is not right, because the temperature itself is high, and the activities of pests will also decrease. Spraying pesticides at high temperature at noon will not only miss the pests themselves, but also greatly reduce the effect.

Therefore, it is suggested that fruit farmers try to avoid the high temperature period at noon and try to choose pesticides at night.

3, do a good job of protection when spraying

When the weather is hot, people will sweat a lot if they basically don't exercise, not to mention taking medicine.

In order to cool down, many fruit farmers wear short-sleeved shorts when spraying drugs, which is very dangerous. When the temperature is high, the pores of human skin expand, and the drugs volatilized and scattered on human skin are easily absorbed by the skin, which can easily cause poisoning.

Therefore, whenever you take medicine, you should wear protective equipment.

Don't take medicine in the morning.

It is cool in the morning, too. Why can't we get some medicine? Because the temperature is low in the morning, if the time is too early, sometimes the dew has not completely evaporated. At this time, pesticides will be diluted by dew on plants, which is equivalent to reducing the concentration of pesticides and making the spraying effect worse.

The above is the introduction of the specific matters of applying pesticide to fruit trees under high temperature.

Generally speaking, in summer, fruit farmers must pay attention to the choice of time when spraying drugs, and at the same time spray drugs according to drug standards, and do not increase the concentration without permission. The most important thing is to wear protective equipment and take a bath in time after spraying drugs to prevent poisoning.
