What about Chinese cabbage aphids?

Cabbage is a vegetable that we often eat. It was reported in the news that the toxic content of cabbage exceeded the standard, resulting in a trough in sales of cabbage. Many people did not dare to buy cabbage during that period. The main reason was that the field management of cabbage was not handled properly during the growth period, and then a large number of pesticides were used to prevent pests and diseases, while aphids were the most harmful to cabbage throughout the growing period. So what we need to know today is how to treat aphids in cabbage. Let's take a look.

1. Seedling stage

There are also many aphids in the seedling stage of Chinese cabbage. At this time, aphids are mainly able to resemble the survival rate and growth of Chinese cabbage, because at this time, Chinese cabbage is still relatively small and fragile, while the sprout mainly gnaws on small pieces of cabbage leaves and Chinese cabbage heart, leaving only white stalks, even small stems. So at this stage, if we are planting in a small area, we can kill the aphids artificially, while in large areas, we can trap and kill the aphids and control them with drugs.

2. Rosette stage

The rosette period is the most exuberant time for cabbage growth, during which the growing leaves of cabbage determine the weight of cabbage, and the main pest at this time is aphids, and the number of its outbreak is more than that of seedling stage, so it is more harmful to cabbage. If it is not controlled in time, it will lead to other diseases, so the impact on cabbage is not only the harm of aphids. In severe cases, it may also cause the whole cabbage to rot or wither and die. We can reduce the occurrence of insect pests by removing weeds in the field, at the same time, we can enhance the resistance of Chinese cabbage by loosening the soil and fertilizing, and we can also kill pests by spreading lime in the field with Guoxing. Of course, you can also use non-toxic agents or soap to control cabbage.

3. Pericardial period

The heart stage of Chinese cabbage is also the most important period for the growth of Chinese cabbage, which determines the quality and yield of Chinese cabbage, and this period is also the period when aphids appear the most. At this time, aphids have a great impact on the quality of Chinese cabbage. At the same time, we can not eat pesticides for control at this stage, because it will have a great impact on the quality of Chinese cabbage, even with low-toxic or non-toxic agents. So how do we get rid of insects? First of all, we need to clean up the withered leaves of cabbage in the field in time, do not let them rot, otherwise they will attract other pests, secondly, we can use trapping method in time, and then we can use net yarn to control pests. If there are too many aphids, we can control them with smoking or with a small amount of phosphorus-free washing powder.

These are some simple methods that the editor would like to share with you today on how to control aphids of cabbage. Here, I would like to remind you that no matter in the seedling stage, rosette stage or heart stage, you can not spray any agents used to control diseases and insect pests within half a month before harvest, because in this way cabbage will also carry some toxins, which will lead to poisoning.
