The Latest Control Methods for Common Pests and Diseases of Mangosteen

Mangosteen is a fruit with high nutritional value and is widely popular, so relatively few people in our country grow mangosteen. The mangosteen tree itself has high resistance, and combined with the characteristics of mangosteen itself, the incidence of disease in mangosteen trees is actually very low, but there will still be cases of disease. Below, Qinnong Web will briefly introduce these diseases to everyone.

1. Aphids

Aphids are a pest that many fruit trees cannot escape; this pest generally appears on fruit trees, and the tender branches and leaves of mangosteen trees are especially favored by aphids. The onset period is mostly concentrated in the days when spring and summer alternate, and once they appear they spread very easily. They manifest as some leaves gradually tending to turn brown, and the leaves begin to curl up; when the leaves are opened, the insects can be seen. A relatively common treatment method is medication, and 50% pirimicarb wettable powder 1000-1500 times liquid is one of the pesticides with fairly good effect.

2. Thrips

This is a disease that harms even the fruit of mangosteen and can easily make mangosteen no longer edible. It mostly occurs in March-April, the days when this pest is frequent. Thrips parasitize the relatively tender leaves and absorb nutrients, then cause the bacteria they carry to seep into the branches and flow to the fruit. The appearance of infected fruit cannot show anything at first, and later it will gradually change color and develop spots, and the fruit will become softer and softer, finally releasing a pus-like substance when pressed by hand. It can be controlled by spraying 90% trichlorfon 800 times once a week for more than one month.

3. Mangosteen Yellowing Disease

This is the most common disease with the highest incidence in mangosteen trees, affecting the growth of the entire plant, and in severe cases it will lead to the death of the mangosteen tree. The disease manifests as an overall trend of yellowing and withering; next, the surface of the bark often appears moist, and some places begin to slowly crack and ooze a yellow thick liquid. Prevention of this disease is very important; the soil must be disinfected well. After the disease occurs, it can be treated with carbendazim, once a week continuously, and once there is some improvement it can almost be stopped.

The above is an introduction to some common pests and diseases of mangosteen and their control methods. Everyone must not neglect its pests and diseases just because the mangosteen tree has high resistance; once these diseases break out, treatment will also be very troublesome, and a moment of carelessness may also affect everyone's economic income. Therefore, everyone should still pay more attention to observation and prevention in daily life.
