In the process of cucumber cultivation in greenhouses, it is often found that cucumber vines or grafted joints rot and flow. The main reason for this phenomenon is that due to infection by pathogens, diseases that invade the shoots and grafts of cucumbers mainly include blight, blight, wilt, and sclerotia. There are two main symptoms of damage:
One is water immersion. The stems were softened and contracted. In severe cases, the epidermis was intact, but the interior decayed. The vascular bundles did not change color and occurred mostly on the grafted interface. The main cause of the disease is epidemic disease, which can be used for spraying and spraying on the new high-fat membrane.
The second is the amber or white jelly that flows out of the interface or the excised wound. This situation is mainly caused by the infestation of blight and blight. The two diseases can be controlled alternately by irrigating roots, applying and spraying. Irrigation can be used with withered Dandan + Baba'an or Huang Weijiu + rooting solution; spray can be used to strengthen the Guate of Gutierin, strengthen the direction of nutrition delivery, need to spray every 5 to 6 days 1 time; Spirit + true bacteriocin or sat guayan + Tian Dan.
