The Weifang readers’ phone call with a mobile number of 152*****843 reflected: I heard that cucumber bagging can improve quality and sell at high prices. So she tried to put a bag of cucumbers some time ago. In order to see if it works, I only try to set about a hundred cucumbers. As a result, the cucumbers of these bags were invariably infected with the disease, light spots appeared watery spots, severe cases started to rotten melons, but the uncropped cucumbers did not find the disease. From a symptom point of view, bagging cucumbers is a bacterial disease. Where is the problem?
According to the above situation, experts believe that neglecting the damage caused by bagging on cucumber fruits and creating an environment conducive to disease occurrence in the bags both promote the occurrence of diseases. For this reason, special attention must be paid to these two aspects during the bagging process.
First, get the right bagging time. Bagging should be done after 10 o'clock in the morning or in the afternoon. Because the humidity of the cucumber surface is small during this time, the wound will heal quickly after bagging, which is not conducive to disease. When the humidity in the rainy weather is high, it is not suitable for bagging.
Second, pay attention to spraying and disease prevention before bagging. Before bagging the cucumbers, apply a protective fungicide such as chlorothalonil to spray them all over the plant. In particular, focus on spraying the body and then bagging. The bagging must wait for the liquid on the body to dry before it is carried out, which can prevent the humidity in the bag from causing the disease and prevent the liquid from dripping and prone to injury.
Again, avoid scratching the body when bagging. Should be careful operation, gentle action, so as not to cause a large wound on the body, open the door for the bacteria infection.
In addition, before cucumbers are bagged, they must pick up residual flowers to prevent them from being infected by pathogens and then infecting the fruits.
Experts also suggested that bagging cucumbers that have already been diseased should be removed as soon as possible and buried deep outside the shed. At the same time, a 1500-fold dilution of agricultural streptomycin with 500 times solution of copper phthalate (DT) should be sprayed through the entire shed.
