Nepenthes plant pests scale insects leaf spot blight

Pitcher plants are so powerful that they can still have pests. Don't pitcher plants specialize in eating insects? Can also be eaten by insects, shell insects are really the nemesis of pitcher plants, pitcher plants have what insect pests? How should we deal with it?

1. Fusarium wilt

The leaves and cages of pitcher plants that were bought soon withered, usually caused by not adapting to the environment. Most of the pitcher plants bought by basin friends just came out of the greenhouse, and they failed to adapt to the environment at home, so they withered.

Solution: cut off the severely withered ones, spray water around, keep the temperature constant, and the temperature difference is too big to control. Just cover it with a transparent plastic bag! This can create a constant temperature and high humidity environment.

2. Leaf spot

See the small dark brown spots on the leaves, basin friends are very worried, they will slowly expand, at first just a little bit of leaf spots, can not deal with the whole leaf!

Hot and stuffy (not ventilated, stagnant water) is easy to get black spots, of course, frostbite should also be avoided, the treatment is very simple, cut off the sick leaves, although it may have a lovely small cage! Cut it out, throw it away, or burn it.

If you want to spray treatment, you can start spraying at the initial stage of the disease to prevent the spread of the disease.

Generally, 25% carbendazim wettable powder solution, 50% topiramine 1000 times, 70% mancozeb 500 times, 80% mancozeb 400600 times, 50% carbendan 500 times, and so on.

Note: buy two more drugs and use them alternately when spraying to avoid drug resistance. This is suitable for all kinds of plants.

3. Scale insects

Shell bugs really hate it! Why does every kind of flower have this thing? They are easy to wither the branches and leaves, or even the whole plant to die, easy to cause coal fouling disease, the crime is extremely heinous. This kind of thing multiplies quickly, the disease resistance is strong, how to do?

Prevention and control methods: check the plants carefully every day, find diseases and insects in time, kill one or two directly at first, kill them with tweezers or brush them off with a soft brush.

If there is too much, cut off the insect branches, insect leaves and diseased leaves and destroy them.

If it is not long after the insects hatch and the medicine is used, it will be enough to spray it once every 10 days and 3 times in a row. 40% omethoate 1000 times, 50% malathion 1500 times, 255imidophos 1000 times, 2.5% deltamethrin 3000 times, etc., can be sprayed.

Note:

Its flowers are very bad, and they like a warm, humid and ventilated environment, so they can usually be kept on the balcony on the back, just see the sun for an hour or two a day, and the cages can be strong.

Whether it is the hanging basin or placed on the table, it should be used as some bracket, waiting for them to climb, of course, it is necessary to grow up! If you die after a while, you can only observe a moment of silence!

In the pitcher plant, we should still pay attention to these diseases, lest the pitcher plant die, the pitcher plant is still very expensive, if the death is too uneconomical, I will be sad for a long time.

Pitcher plant fengshui: the breeding method of pitcher plant

I believe that pitcher plants are no stranger to us. In many people's homes, pitcher plants are used to catch insects and kill mosquitoes, and planting them on the balcony and in the courtyard is also a kind of sensory enjoyment. So today let's take a look at how to raise this strange pitcher plant. This issue of plant fengshui will take you to learn about the breeding methods of pitcher plants.

The basic information of pitcher plant: pitcher plant (Latin name: Nepenthessp.), also known as pitcher plant, monkey water bottle, monkey courtyard, piggy cage, Leigong pot, etc., is the general name of all species of pitcher plant, belongs to tropical insectivorous plants, it has a unique nutrient-absorbing organ-insect cage, the insect cage is cylindrical, the lower half of the cage is slightly expanded, and the mouth of the cage has a lid, so it is named because it is shaped like a pig cage. There are about 170 wild species of the genus pitcher plants in the world, but there is only one species in Guangdong, China, and there are more than 1000 horticultural species. Now the excellent species of pitcher plants are mainly used in flower shows.

The cultivation method of pitcher plant soil: loose, fertile and breathable rotten leaf soil or peat soil is better. A mixed substrate of peat soil, water moss, charcoal and fir sawdust is often used in pots.

Watering: pitcher plants are sensitive to water. Pitcher plants can only grow and develop normally under high humidity conditions. During the growing period, pitcher plants need to spray water frequently, 4 or 5 times a day. If the temperature changes greatly and is too dry, it will affect the formation of leaf cages.

Sunshine: the pitcher plant is an epiphytic plant, which often grows under the forest or on the north side of the rock. The natural condition is semi-overcast. Under the strong light in summer, the leaves must be shaded, otherwise the leaves are easy to burn and directly affect the development of the leaf cage. However, under dark conditions for a long time, the leaf cage forms slowly and small, and the color of the cage surface is dim.

Temperature: the suitable temperature for the growth of pitcher plant is 2530 ℃, 2130 ℃ from March to September, and 1824 ℃ from September to March of the following year. The winter temperature was not lower than 16 ℃, the plants below 15 ℃ stopped growing, and the leaf edges suffered frost damage when the temperature was below 10 ℃.

Fertilization: pitcher plants do not need special fertilization, because pitcher plants can usually feed on insects to transform nutrients, if pitcher plants have insects to eat, there is no need to apply fertilizer.

Insect pests: pitcher plants are often harmed by leaf spot and shell insects. Leaf spot disease was sprayed with 1000 times of 50% Dysen zinc wettable powder. The shell worm was sprayed with 2000 times of 40% dimethoate EC.

Pruning: the cage of the pitcher plant is a kind of abnormal leaf, so it will age and die like the leaves of other plants. Generally speaking, each cage can survive for several months under suitable conditions. When it has withered, it can be cut off to make the whole plant look more beautiful, but this is purely for the sake of beauty and has nothing to do with the health of the plant.

Pitcher plant breeding precautions 1, pitcher plant flowers do not have any ornamental value, the flowers are small and flat, only a few varieties of flowers are more bright, in addition, pitcher plant flowers will also give off a bad smell, so try not to breed indoors, the courtyard balcony is the best choice.

2. The pitcher plant is a vine, and it must be attached in order to stand, so it is necessary to set up a support for the pitcher plant. In order to set up the support, it is necessary to use larger flowerpots, on the other hand, larger flowerpots can hold more cultivation value, make the flowerpots stable and heavy, and can support large pitcher plants without being blown down by the wind.
