What are the common pest and disease control methods for mangosteen?

Mangosteen is a widely popular fruit with high nutritional value, so relatively few people in our country grow mangosteen. The mangosteen tree itself has high resistance, and combined with the characteristics of the mangosteen itself, the incidence of disease in mangosteen trees is actually very low, but cases of disease still occur. Below, Qinnong Network briefly introduces 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. The symptoms are that some leaves gradually tend to turn brown, and the leaves begin to curl up; open the leaves and you can see the insects. The more common treatment is medication, and 50% pirimicarb wettable powder 1000-1500 times dilution is one of the pesticides with fairly good effect.

2. Thrips ⟧7⟧This is a disease that harms the mangosteen fruit and can easily make the mangosteen inedible. It mostly occurs in March-April, the days when this pest is frequent. Thrips parasitize the relatively tender leaves to absorb nutrients, and then cause the pathogens they carry to seep into the branches and flow to the fruit. The infected fruit shows nothing unusual on the outside at first, but later slowly changes color and develops spots, and the fruit becomes softer and softer, until finally pressing it with your hand causes a pus-like substance to flow out. You can spray 90% trichlorfon 800 times dilution once a week, continuing for more than one month for control.

This is a condition that harms mangosteen fruit and can easily make the fruit unfit to eat. It occurs mostly in March and April, when pest problems are frequent. Thrips parasitize the relatively tender leaves and feed on them, which then allows the bacteria they carry to penetrate the branches and flow to the fruit. In the early stage, nothing unusual can be seen on the surface of infected fruit, but later it gradually changes color and develops spots, and the fruit becomes softer and softer until, when pressed by hand, a pus-like substance oozes out. To control it, spray 90% trichlorfon at 800 times dilution once a week for more than one month.

3. Mangosteen yellowing disease ⟧9⟧This is the most common disease of mangosteen trees with the highest incidence rate. It affects the growth of the entire plant, and in severe cases it causes the mangosteen tree to die. The symptoms of the disease are an overall trend of yellowing and withering; secondly, the surface of the bark often appears moist, and some places begin to slowly crack open, oozing a yellow thick liquid. Prevention of this disease is very important; you must do a good job of disinfecting the soil. After the disease occurs, you can use carbendazim to treat it, continuing once a week, and once there is some improvement it is about time to stop.

This is the most common and most frequently occurring disease of mangosteen trees. It affects the growth of the entire plant, and in severe cases it can cause the mangosteen tree to die. The disease appears as an overall trend of the plant turning withered and yellow; in addition, the surface of the bark often appears moist, and some areas slowly begin to split and ooze a yellow thick liquid. Prevention of this disease is very important, and soil disinfection must be done well. After the disease occurs, it can be treated with carbendazim, once a week, and once there is some improvement, it is about time to stop.

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 is also very troublesome, and a careless mistake can affect everyone's economic income. Therefore, everyone must still pay more attention to observation and prevention in daily life.
