How to prevent and control root rot in wampee (Huangpi) trees? A detailed look at the latest measures

Wampee trees often develop root rot during their growth, and it generally occurs concentrated in the rainy summer, which coincides with the wampee fruit ripening season. Once root rot occurs, the fruit cannot obtain nutrients, which affects its growth and ultimately affects yield and quality. So how should wampee root rot be prevented and controlled? Let's learn about it together.

I. Symptoms of wampee root rot

Root rot is a disease that occurs on the root system, so when it first begins, no abnormality can be seen on the plant. If the disease develops to a certain degree and obvious symptoms appear, the plant will show yellowing leaves, the yellowing spreading and the branches gradually drying up. If it is a seedling, a gentle pull will uproot it, and the root system will be left as bare roots with only the xylem remaining, because most of the root system has rotted and turned black underground.

II. Prevention and control measures for wampee root rot

1. Good terrain

Choose a plot with higher terrain or plant on raised ridges. It is best to choose loose soil rich in organic matter. Higher terrain can prevent rainwater soaking, while loose soil can promptly drain away accumulated water, make use of soil air circulation, and avoid root suffocation.

2. Drainage

If planted in a low-lying place that easily accumulates water, where rainwater flows through for a long time when it rains, you can dig drainage ditches of appropriate depth beside the fruit trees, ensuring the water level is more than 20 cm below the original ground surface. This can quickly drain rainwater away, keep the soil around the roots in an airy state, and at the same time pile the dug-out soil high around the base of the wampee tree to facilitate upward root growth in the future.

3. Chemical control

Once the leaves are found to be withering, it indicates that the underground roots have begun to rot. This condition is more obvious under sunlight, so the evaporation of water from the plant should be reduced. The best method is to prune away most of the leaves. Then irrigate the underground root system with a disinfecting solution, and pair it with a rooting agent to speed up the recovery of tree vigor. After treatment with the chemicals, keep the soil relatively dry and airy.
