Cabbage radish to keep safe, it can be seen that in daily life, cabbage radish for people's healthy diet is important.

However, the production process of cabbage radish is not so simple, especially the cabbage green insects, always want to win people's love, in the growth process of radish cabbage, they often take the lead, the good end of the leaves are chewed everywhere holes, not only affect the growth of radish cabbage, but also affect people's appetite.
Vegetable green insects, also known as vegetable powder butterflies, is the enemy of cruciferous plants including cabbage radish, the greatest harm to cabbage radish is the larvae, they are adults hatched after laying eggs, with the leaves of the cruciferous family as the main food, the amount of food is amazing, and the impact on vegetable production is great. At present, the common methods of controlling green worms in production are:
1. Use natural enemies for natural prevention and control. Natural predators such as broad-eyed bees, reddish velvet cocoon bees, and phoenix butterflies are used to kill insects. For example, during the peak of the cocoon bee, the use of chemical pesticides is prohibited to protect the larvae of the red-eyed bee, so that it can hunt the larvae of the green worm.
2. Drug prevention and treatment. In the early stage of the occurrence of young larvae of caiqing insects, spraying 800-1000 times liquid of Rhaebacterium or 20 larval units per mu of vegetable powder butterfly granule virus has a good control effect on caiqing insects.
However, for the general vegetable farmers, in addition to pesticides to treat insects, biological insect treatment is difficult to control, but also difficult to do, for this reason, people in the production practice has explored a lot of soil methods that can cure insects without spraying.
Once, I went to the farm to visit a friend. During the time when I was waiting for my friend, I went to the vegetable field she planted and walked around, and saw that there was an uncle in her vegetable garden who was managing the vegetable field, at that time, the uncle was spraying water on the vegetable field, and when he saw that the vegetable field was not dry, I asked him, Why do you have to spray water on the vegetable field? I didn't expect him to say, you don't understand this, I'm treating insects. I wonder, can spray water also cure insects? He said that the most feared thing about vegetable green insects is water, and I spray water on the leaves of vegetables regularly every afternoon, not only to water, but also to cure insects. You see, these green vegetable leaf surfaces do you see if there are any bugs?
After his prompting, I squatted down and carefully examined the green vegetable leaf surface, and sure enough, it was smooth and complete, and I could only occasionally see a little insect eye. After the friend returned, he also confirmed what the uncle said, and said that they relied on this soil method to cure insects and eat green food. After saying that, I let the uncle pick a lot of green vegetables for me, and after going back to stir-fry, the taste was really good, and there was no residual taste of pesticides.
This field experience also made me very emotional, many vegetable farmers in order to grab vegetables, there is no way to use a large number of pesticides, although this can also cure the insects, but the degree of food safety will be different. And a soil method can cure the insects, but because no one to summarize and promote, but only limited to a small range of use. This also confirms from another side that the master is in the folk.
