You may not be familiar with the jasmine topics in the floral clinic, but the prevention and control of jasmine stem rot will definitely be helpful to you. Let's learn about it together!
The disease occurs at the base of the stem, with initial symptoms being brown spots that are watery in appearance. The lesions expand longitudinally to form streaks. The edges are dark brown, and the center is grayish-brown. In the later stage, the lesion tissue rots and splits longitudinally, and black granular substances appear.
The disease occurs throughout the year during greenhouse maintenance, especially severe in early spring. It can also occur outdoors from August to September. High temperature and humidity conditions are conducive to the occurrence of the disease.
Control methods:
① When potting flowers, a 0.2-0.4 degree lime sulfur solution can be sprayed;
② A 70% thiophanate-methyl solution diluted 600-1000 times can be applied to the lesions or stems, or a 500 times solution of carbendazim can also be effective.
