Fruit trees spray in the summer have "four bogey"

When the temperature is too high, some fruit growers think that the higher the temperature, the better the insecticidal effect of spraying pesticides, but it is not. Spraying at high temperature and strong light, because most of the pests stop moving, hiding in the cool backlight, the medicine is not easy to spray in place, and the pesticide volatile loss is high at high temperature, and the drug decomposition is fast, so the spray effect is reduced. In addition, when the temperature is too high, the drug is sprayed, and the agent is highly toxic due to its strong volatility.

When the two bogey dews are not dry, some of the farmers prefer to spray when the morning is cool. However, because the morning dew is not dry, the drug is diluted by dew after spraying, which will reduce the efficacy, and at this time the pest has not yet come out, so the insecticidal effect is not ideal.

The concentration of the three bogey liquids is too high to save trouble. The fruit growers spray less water in the high temperature season in summer, and the concentration of the liquid is too high. After the liquid is sprayed on the foliage of the crop, the water is evaporated quickly, which is easy to cause phytotoxicity.

Four bogey do not add protective spray in the summer when the spray is cool, some fruit farmers do not take any protective measures, and sometimes even "bare-chested", this can easily lead to skin absorption of pesticides and poisoning.

In response to the above problems, it is recommended that the fruit farmers spray in the summer. First, they should choose cloudy or sunny days 8 to 10 am (after dew dry), 5 to 7 pm (before and after sunset), spray when the pests are active; Appropriately increase the amount of water to ensure that the dosage of each acre is more than 45 kg; the third is to wear protective clothing, wear a mask, and timely clean the body after spraying to prevent pesticide poisoning.
