What diseases does Hylocereus spp.

Hylocereus scab

The scabs mainly attack the nodes of the Ophiopogon japonicus, causing light brown to brown spots to appear on the nodes.

Scab disease is mainly caused by fungi. Fungal spores are spread by air currents, rain splashes, or the activities of small insects, and invade through stomata or epidermis to cause disease. Rainy weather is prone to disease.

When scab breaks out in the Oriole, individual spots can be dug out with a knife, or it can be sprayed with 50-100 times diluted 40% triadimefon carbendazim or 45% triadimefon thiram, 2-3 times, once every 7-15 days. If the disease is more serious, it can be propagated by cuttings.

Anthracnose

Anthracnose mainly harms fleshy stems, causing spots to appear on the stems.

When anthracnose occurs, the diseased part should be removed and 50-100 times diluted 30% copper oxychloride suspension, or 100 times diluted 70% thiophanate-methyl + 75% thiophanate-methyl, or 50 times diluted 25% carbendazim wettable powder should be applied to the diseased part 1-2 times or sprayed on the plant. Cuttings are also a method.

Other diseases of Hylocereus

The Oleander plant can suffer from soft rot. When the disease occurs, the plant becomes soft and the epidermis erodes, and the whole plant can die within two or three weeks.

The ocotillo also suffers from stem blight, which causes the plant to fade, develop mildew, and rot and dry up.

The basal rot of the Olympia cinerea mainly affects the roots and the base of the plant. When the disease is mild, the root system is normal and the plant can continue to grow.

The above-mentioned diseases are mainly caused by pathogens that parasitize in the soil or other plants. In a hot and humid environment, the proliferation of pathogens will endanger the health of the Ophiopogon japonicus.

To treat these diseases, you can disinfect the soil, disinfect the flower pots, or simply replace them with heart pots. The second thing is to detect the disease in time and treat it in time to prevent the disease from spreading further. The last point is to control watering, because if the pot is too moist, various diseases may easily break out, so ventilate frequently.
