What are the common pests of persimmon trees? The latest complete pest guide
Pests are one of the things growers dislike most, yet they have no choice but to deal with them. This is especially true for persimmon tree pests, and these pests are extremely prone to appearing on the fruit, causing reduced yields. Pests like scale insects are among the more common diseases of persimmon trees, so what symptoms do these pests have? And how should they be dealt with? Now let's learn about these common pests together with the editor.
1. Persimmon scale insect
As one of the main pests of persimmon trees, the persimmon scale insect is a major headache for persimmon growers. This pest is extremely prone to attaching itself to persimmons, then densely covering the entire persimmon and spreading. This pest mostly occurs in summer, and in more serious cases concentrates in September-October, feeding on persimmon sap. In the early stage it shows as some egg-like objects on the persimmons or branches and leaves, with relatively low density; in the later stage they are distributed more densely on the persimmons, and from a distance it looks like the persimmons are covered with a layer of white protruding material interwoven with purplish-red material. Immediately prune off the affected parts, and spray the persimmon tree with wax scale insecticide solution for control.
2. Persimmon fruit borer
The persimmon fruit borer is a pest that is not easy to spot, because its early-stage larvae bore in from the junction at the persimmon calyx and finally enter the fruit. The disease mostly occurs in August-September, mainly harming mature fruit. When you find that relatively nearby persimmons on the tree appear waxy yellow, or differ greatly from other normally growing persimmons, and the tree frequently drops fruit, with the calyx area of the fallen fruit turning black and showing traces of pests, then it is very likely to be the persimmon fruit borer. For this pest, early prevention must be done well, such as clearing away the thicker old bark areas, which are the most likely places for pest sources to remain. After the disease occurs, drugs such as fenitrothion can be used for treatment.
3. Persimmon leafhopper
The persimmon leafhopper is a pest that occurs relatively frequently, with the main occurrence period concentrated around May-June. It looks like a smaller version of a cicada, and its outer color is yellowish-white. This is one that is relatively easy to find, but because persimmon trees are fairly tall you still need to observe carefully. It generally attaches to the shaded parts of persimmon tree leaves, near the leaf veins. It is highly mobile and capable of flying, so it is not easy to catch. When it occurs, it is generally recommended to directly use chemicals to eliminate it; cypermethrin is a chemical that can be used to deal with it.
These three are basically the more common pests of persimmon trees, but they will also differ depending on the region. In terms of pests, the main protective measure for persimmon growers is to eliminate the pathogens in advance. Prevention after each year's harvest must be done thoroughly; for related information you can follow our website.
