Are there any vegetables that work better at night?

Like lettuce, leeks, cabbage, etc. at night spraying effect is better, because the general night can better absorb the ingredients in the pesticide, can play a good sterilization and insecticidal effect, afternoon spraying, under the sunshine, the liquid dries faster, can better penetrate into the leaves, so that the effect of medication can be improved.

Water spinach and sweet potato seedlings are very good at night pesticides, and the leaves can absorb pesticides well, becoming particularly green, and the vegetables are also much more tender.

Leeks and cauliflower. Because these two dishes can better absorb the ingredients in pesticides at night.

Hello: Any time slot after 2 p.m. can be sprinkled.

Because this time is the time when vegetables receive the most sunlight, and there is no dew. Easy to walk.

The temperature is high, and it is generally played in the evening.

In fact, spraying pesticides for vegetables does not have to be at night, the sight is not good, the operation is inconvenient, and it is mistaken for stealing vegetables. The best time to apply pesticides should be in the evening.

Especially in the hot summer, the weather is so hot that not only do farmers and friends not want to work in the fields, but even insects have found a shady place to hide, maybe they are dreaming in a shady place.

Therefore, choosing to spray pesticides during the day is not easy to spray on insects, especially for those insecticides that focus on contact killing.

In addition, spraying pesticides in the hot daytime is not safe for the human body, sweating profusely, in case the sprayer leaks, the liquid medicine is on the top of the list, and it also increases the risk of poisoning.

There are also some pesticide ingredients that are easy to decompose when they are light, and they are sprayed directly at high temperatures, which not only affects the efficacy, but also easily causes harm to crops, which is often said to be easy to produce pesticide damage.

Without further ado, what about which vegetables are better sprayed with pesticides in the evening?

In fact, this time is suitable for most vegetables, and before the sun sets, the light is still good, and the temperature is starting to gradually become comfortable.

Lepidopteran pests hiding in the leaves (diamondback moth, Spodoptera exigua, Spodoptera litura, ground tiger, Spodoptera exigua, etc.), Coleopteran pests hiding in the soil (jumping beetles), or tasselopteran pests (thrips) hiding among flowers, or erratic homoptera pests (whitefly, whitefly, aphids), have begun to come out to move, whether it is out for a walk and night run, or square dancing, before coming out, they must have a full meal.

Take advantage of the opportunity for these pests to come out and spray, that is the most suitable time, just like the thrips that are called, during the day, the carob flowers are afraid of heat, they will automatically close, and the thrips will hide in the flowers, spray more pesticides, they are safe. In the evening, when the weather is cool, the carob flowers bloom again, so it is very important to take the opportunity to spray.

Looking at the instructions for the use of pesticide labels, the vast majority of them are written that it is recommended to spray after 4 o'clock in the afternoon, which still has a certain scientific reason, which has a positive significance for the rational use of pesticides and fully improving the efficacy. But you probably haven't read which pesticide label specifically states that you want to spray at night, maybe you have been misled.
