If we don't pay attention to the three highest diseases of domestic rubber trees in summer, we will only take precautions in advance.

The leaves of the rubber tree are thick and broad, the color is thick green, the surface looks like a layer of wax, and the top bud is bright red, and the large leaves are very similar to the red tassel drooping, quite a charm, is a famous potted foliage plant, many flower friends especially like to decorate the living room, study and so on.

Rubber tree is relatively easy to maintain a kind of flowers, but in summer, the highest incidence of these three diseases, again and again do not pay attention to only the pot, early prevention is very necessary.

1. Anthrax

Rubber trees are most likely to suffer from anthracnose, especially in summer, especially in the peak period of the disease. as long as the leaves are eroded, the main symptoms are as follows: round or oval gray spots appear on both sides of the leaf veins, and in severe cases, the disease spots extend to the whole leaf, and eventually affect the whole bead, resulting in death.

Prevention and control methods:

[1] in the hot and humid environment in summer, we should pay attention to ventilation and put it in a place with good ventilation. Combined with pruning, some diseased branches, old leaves and dead leaves should be pruned in time to reduce infection.

[2], the branches and leaves need to be disinfected once a month, 0.1% Bordeaux solution or 0.5% potassium permanganate can be sprayed on the branches and leaves evenly; in the event of the disease, carbendazim can be diluted 500 times.

2. Grey spot

Gray spot disease is mainly caused by infected wounds, the main symptoms of the leaves are dark brown, and there are black grains, and then slowly dry up.

Prevention and treatment: when pruning branches and leaves, it is best to apply lime powder or potassium permanganate to the wound, and then put it in a cool and ventilated place and wait for the wound to dry.

When gray spot disease occurs, you can directly use carbendazim dilution 1000 spray to treat the disease.

3. Root knot nematode disease

Root-knot nematode disease is mainly aimed at the root system, which will constantly erode the root system, resulting in many nodules of different sizes on the fibrous root, causing the root system to rot, and finally leading to the death of the whole rubber tree.

Prevention and control methods: White sugar water can be used for prevention and control. Watering one hundred white sugar water once a month can promote the reproduction and growth of beneficial bacteria in the soil, and then destroy the living environment of root-knot nematodes; it can also be applied 15% Tiemiake granules, about 1 g of 1kg soil, can effectively eliminate root-knot nematodes in basin soil.
