Things to Note When Spraying Fruit Trees in Summer, a Full Breakdown of the Latest Key Points

High temperature and high humidity in summer easily cause fruit tree pests and diseases to spread and run rampant, and summer is also a period when fruit trees are sensitive to pesticides. Once the pesticide concentration is too high or the spraying method is improper, it can very easily cause pesticide damage. So what should be noted when spraying fruit trees in summer? Let's find out together.

1. Spraying time

Many fruit growers think when spraying that the higher the temperature, the better, but this is not actually the case. When spraying under high temperature and strong light, most pests will stop their activity at this time and hide in cool places, so it is not easy for the pesticide to be sprayed onto them. Moreover, the pesticide volatilizes quickly under high temperature and its efficacy breaks down quickly, so spraying at this time will reduce the pesticide's effectiveness. In addition, when spraying under high temperature, because the pesticide is highly volatile, it is very easy for the person spraying to suffer poisoning. Many fruit growers also like to spray in the cool morning, but at this time the dew has not yet dried, and after spraying the pesticide will be diluted by the dew, reducing its effectiveness and resulting in poor control results. The correct spraying time is from 9-10 am or after 4 pm. These two time periods avoid both the dew and the high temperature period, giving the best spraying results.

2. Pesticide concentration

The concentration of the pesticide must be well controlled. During the fruit tree growing season, fruit trees are relatively sensitive to pesticides. Too high a concentration easily causes pesticide damage, while too low a concentration reduces the control effect, so the pesticide mixing concentration must be strictly controlled. According to the sensitivity of fruit trees to pesticides, reasonably determine the type and concentration of pesticide to use. For example, Bordeaux mixture is often used on apples, pears and grapes, but peach trees are relatively sensitive to it, so it is generally not used on peach trees. There are many cases like this, so before use you must understand their characteristics and mix them reasonably.

3. Spraying operation

Summer is hot and scorching, and many people spraying pesticides take no protective measures at all just to feel cool for a moment, and some even spray bare-chested. This very easily leads to the skin absorbing the pesticide and causing poisoning. Therefore, when spraying, wear protective clothing and a mask, and after spraying, wash the whole body to avoid pesticide poisoning. When spraying fruit trees, be sure to spray evenly and thoroughly. In summer, fruit trees have luxuriant branches and leaves, and pests are highly concealed, so at this time spraying must be even, allowing both sides of the fruit and leaves to be covered by the pesticide, and according to the growth habits of the pests, concentrate the spraying for control on the places where they live.

4. Pay attention to pesticide resistance

When spraying pesticides, scientifically rotate the types of pesticide and mix pesticides, and at the same time add Texiao Wang to the spray liquid to improve the pesticide effect, avoid continuous use of the same pesticide causing pests and diseases to develop resistance, and also avoid losing pesticide effectiveness after rain.
