How to treat Clivia yellow spot disease

How to treat Clivia yellow spot disease

1. Causes

This is caused by reasons such as burns from the sun on the leaf surface, cold wind, the spread of bacteria in local bites by slugs, snails and other pests, or the enlargement of wounds after trauma. If the leaf tips turn yellow first, it is mainly because root rot interrupts the nutrient supply to the leaves. This phenomenon can be caused by using too much fertilizer or too little soil or using poor soil.

2. Prevention and control methods

First of all, we must prevent the plants from root rot so that the leaves can get enough nutrition. Secondly, we must prevent external injuries and prevent the spread of wounds. The amount of fertilizer applied must be controlled well, and excessive fertilizer should be avoided. In summer, do not water the pseudobulbs of mature flowers. In summer, we must pay attention to ventilation, cool down, strengthen management, and regularly spray carbendazim, thiophanate-methyl, methyl tolbutamide, agricultural streptomycin and other sterilization drugs for prevention and control, which can reduce and eliminate the occurrence of leaf spot and leaf yellowing.
