What are the latest precautions for spraying fruit trees in summer?
We are now in the dog days of summer, with extremely high temperatures. For orchard management, high-temperature weather favors the spread of weeds, pests and diseases, so prevention and control management must be done well. Pest and disease control cannot be done without spraying chemicals, but spraying fruit trees under high-temperature conditions has certain restrictions. If handled improperly, it will backfire. So what should be noted when spraying fruit trees in summer? Let's find out together.
1. The chemical concentration should not be too high
When spraying fruit trees in high-temperature weather, note that the concentration of the spray solution should not be too high, because in a high-temperature environment the water in the spray solution evaporates very easily, so the water in the chemical diffuses and disperses very quickly, which also increases the concentration of the spray solution to a certain extent. If the concentration of the spray solution itself is already relatively high, it can very easily cause chemical damage to the fruit trees under high-temperature conditions, so farmer friends should strictly follow the application standards when spraying in the high summer temperatures.
2. Do not spray at noon
Summer noon is the hottest time of the day. Many farmers are eager for quick results and like to spray at high noon, thinking that the effect will be faster. In fact, this is a wrong practice, because the temperature at noon is extremely high, and pests also decrease accordingly. Spraying at noon not only fails to reach the pests themselves, but also, combined with the rapid evaporation of the chemical, greatly reduces the effect. So fruit tree growers are advised to try to avoid the high-temperature period at noon and choose to spray in the evening.
3. Protective measures must be taken
In high temperatures, people sweat a lot even without exercising, let alone doing physical work like spraying. Many fruit growers wear short sleeves and shorts when spraying to stay cool, which is very dangerous behavior. High temperatures cause the pores of human skin to expand, and after the spray solution evaporates and drifts, it comes into contact with human skin, is absorbed through the pores, and thus causes poisoning. So no matter when you spray, you must take protective measures to avoid chemical poisoning.
4. Do not spray in the early morning
The early morning weather is cool, which should be the best time to spray, so why can't you spray then? This is because the temperature in the early morning is relatively low. If you spray too early, the dew has not yet completely evaporated, and the spray will be diluted by the dew on the plants, which lowers the concentration of the spray solution and results in poor effectiveness.
