Cucumber target spot disease is not unresolvable
I often received telephone calls from farmers who planted cucumbers, reflecting the inability to cure the cucumber target spot. The author's analysis is mainly caused by two reasons. First, the plants are poorly tolerant. Recently, the occurrence of serious diseases has a direct relationship with the decline in the resistance of plants. With the rising of external temperature, the growth of plants is accelerating. Many vegetable growers continuously increase the number of pods in order to pursue high efficiency. The nutrient consumption for reproductive growth is too large, and thin leaves and poor growth are bound to cause the disease resistance of plants to decline. It is recommended that vegetable growers should reasonably keep their melons according to the growing trend of the plants. Blindly pursuing yields will easily lead to a decline in the disease resistance of the plants and premature aging of the plants. Second, blindly medication. As for the pesticides used for the target crops, many pesticides were found in the vegetable shed of a vegetable farmer. According to the vegetable farmer, these were used to prevent and cure target spot disease, but the effect was not obvious. . Blind medication is also one of the causes of the increasing severity of the disease. Therefore, when the disease occurs, it is necessary to judge the condition and use drugs rationally. Cucumber target spot disease can be used for foliar sprays, such as 500 times the number of Kashira No.1. At the same time, the environment of the greenhouse can be adjusted to reduce the humidity, and the development of the disease can be effectively suppressed.
