1. Pesticide irrigation and root control: In the early stage of disease, 70% of dexamethasone WP 800 to 1000 times can be used to irrigate the roots. Each root can irrigate 500 ml of diluted liquid, every 7 to 10 days before irrigation. Irrigation 2 to 3 times. When used, spray with 50% Daisen ammonium water 1000 times, do sprinkler irrigation, the effect is better.
2. Chemicals control pests.
Underground pests, such as breeding flies, cockroaches, cockroaches, ground tigers, etc., as well as ground pests, such as cabbage caterpillars, diamondback moth, vegetable cockroaches, big cocoon leaf beetles, yellow song strips, etc., should be promptly controlled with chemicals. It is very important to control pests, because pests not only directly harm cabbage, but also cause insect wounds, providing conditions for the invasion of soft rot pathogens.
It should be noted that due to the long infection period of soft rot pathogens, the effect of one or two control measures is not ideal, and various measures should be taken for comprehensive prevention and control, namely, agricultural control, biological control (such as seed dressing, soil disinfection, and irrigation , spray), a ring buckle in order to receive good results. In addition, when chemical pesticides are used for control, pesticides should be used with particular caution. For example, copper preparations are sensitive to cabbage. So, 50% DT, 14% ammonia,
77% can kill, 50% amafrost, Bordeaux and other pesticides as much as possible. Because experience tells us that using 50% DT wettable powder to spray 500 times on the cucumber to prevent bacterial keratoses, there is no phytotoxicity, but there is a phytotoxicity on the application of cabbage. Therefore, applying DT to cabbage can only reduce the concentration and increase the amount of water. Sprayed 1000 times, although no phytotoxic cabbage, but the effect is not ideal. Therefore, it is advisable to use copper as the pesticide for cabbage to avoid injury and damage.
