What precautions should be taken when spraying fruit trees in summer heat?

There are quite a lot of fruits on the market in summer, and it is also the most difficult season for growers to manage, because the temperature is very high, and it is very easy for pests to cause rotten fruit and failure to bear fruit. At this time, some pesticides have to be sprayed to reduce the invasion of pests. Fruit trees are highly sensitive to pesticides during summer high-temperature weather, and fruit growers can easily use pesticides improperly. So what precautions should be taken when spraying fruit trees in summer high-temperature weather?

Precaution one: master the spraying time

Fruit growers have a misunderstanding about the spraying time, thinking that the higher the temperature, the better the spraying effect. In fact, when the temperature is particularly high, the pests all hide away to cool off, and even if pesticides are sprayed, they cannot be hit. In summer, the effect of pesticides takes hold relatively quickly and also breaks down quickly. At this time, even if pesticides are sprayed, the expected effect may not be achieved. Spraying pesticides in summer high-temperature weather also has another disadvantage: it easily poisons the person spraying, because the pesticide effect is relatively strong.

Spraying pesticides when the morning is relatively cool is also not very ideal, because at this time there is still a lot of dew, and after spraying, the pesticides will be diluted by the dew, so the pesticide effect itself is reduced, and the control effect is not obvious.

In summary, the generally good time for spraying is around nine or ten in the morning or after four in the afternoon, when the spraying effect is relatively good.

Precaution two: control the concentration of the pesticide well

Fruit trees are relatively sensitive to pesticides during their vigorous growth period, so when the pesticide concentration is relatively high, pesticide damage is likely to occur. If the concentration is too low, the pest prevention effect will not be achieved. At this time, we must rationally use pesticides according to the sensitivity of different varieties of fruit trees to each pesticide. For example, apples and grapes often use Bordeaux mixture, but the same pesticide is not suitable for peaches, so before spraying, you must understand its characteristics, so as not to fail in prevention and control while also harming the fruit trees themselves.

Precaution three: spraying personnel should pay attention to safety

Many fruit grower friends do not take protective measures when spraying pesticides, and some even go bare-chested. This is irresponsible to their own bodies, and it is very easy for the pesticide to be absorbed through the skin and cause poisoning. Therefore, when spraying pesticides, fruit growers must pay attention to wearing masks and protective clothing. After spraying pesticides, they should take a shower in time and clean their mouth and face, so as to avoid poisoning.

Precaution four: fruit trees have pesticide resistance

Spraying pesticides is just like taking medicine when a person is sick. After taking one medicine for a long time, resistance to that medicine develops, and the next time this kind of illness occurs again, the effect will not be so obvious. The same is true when fruit trees use pesticides. Pay attention not to continuously use one pesticide, but to rotate types or mix pesticides.
