In the greenhouse cucumber cultivation process, it is often found that the cucumber stems or the graft interface is rotted and glued. The main reason for this phenomenon is that due to the infection of pathogens, the diseases of the stems and grafts of the above-ground cucumbers are mainly diseases such as blight, blight, wilt and sclerotinia. There are two main symptoms of victimization:
Â
One is water-soaked. The stems are softened and contracted. In severe cases, the epidermis is intact, but the internal decays, and the vascular bundle does not change color, which occurs more than the graft interface. The main disease is due to the epidemic disease, and it can be applied by foliar application and mildewed high-fat film.
Â
The second is the amber or white gel on the interface or the wound after picking up the melon. This situation is mainly caused by the infection of blight and blight. These two diseases can be alternately controlled by three methods: irrigation, smearing and spraying. Tian Dan available IRRIGATING Fusarium wilt or yellow BaBaAn + + rooting insulating liquid; spray available strong breath the Guadi Guadi thickening, fortified targeted delivery amount required every 5 to 6 days, spray; applicator available Zuogua Ling + bacteriocin or sit Gua Ling + Tian Dan.
