How to scientifically control moso bamboo diseases and pests? Is there any good way to do this?

You can give more insects to the bamboo, which is good, so that the insects have more reasons to die.

The best thing to do is to spray antiseptic and insecticidal drugs every 7 days or so, so that pests and diseases can be controlled.

To control bamboo borer, bamboo locust, bamboo spotted moth and bamboo shoot fly, trichlorfon can be sprayed to kill, or dichlorvos smoke fumigation. Spodoptera exigua and bamboo weevils should be dug up in time to kill the larvae. Loosening the soil and weeding in winter can eliminate pests hiding in the grass and soil.

The main diseases of moso bamboo are blight disease and water blight. ”

Anthracnose of palm bamboo disease.

Symptom. Anthrax is one of the important diseases of Moso bamboo, which mainly affects the leaves of Moso bamboo. At the onset of the disease, semicircular or amorphous spots will appear on the tips or edges of moso bamboo, which are yellow-brown or gray-brown. When the air is too humid, cinnabar needle-sized drops appear on the leaves.

Prevention and control methods. Combine pruning in winter and spring to remove fallen leaves and weeds from the surface of the potting soil. In the early stage of the disease, 600-800 times of Guoguang Yinji wettable powder, Guoguang carbendazim, chlorothalonil can be sprayed regularly for prevention and control, with an interval of 7-10 days, and 400-600 times of Guoguang Nagin wettable powder or 500-600 times of Guoguang Bixian EC can be sprayed for prevention and control, a total of 2-3 times.

Spotted leaf disease, a disease of palm bamboo.

Symptom. Leaf spot disease occurs in moso bamboo. Small yellowish-brown spots appear on the leaves at the beginning, which gradually expand into striped markings and merge into irregular necrotic spots.

The first parts affected are the tips and edges of the leaves. In severe tremors, the leaves shrank and the plants die.

Prevention and control methods. Strengthen management, do not apply nitrogen fertilizer, it is advisable to apply more potassium fertilizer, and improve plant disease resistance. At the beginning of the disease, 50% gramadan wettable powder 300 500 times, once a week, a total of 3 times.

Bud rot of palm bamboo disease.

Symptom. Bud rot mainly affects young shoots and young shoots. At the beginning of the disease, the leaves first wither, turn brown, and then droop.

The pathogen spreads from the young leaves to the rest of the plant, causing the plant to stop growing and slowly decay, giving off an unpleasant odor. The disease occurs mainly in the rainy season, with a temperature of 20 to 25 and a relative humidity of more than 90%. If the humidity stays for a long time, it is easy to get sick.

Prevention and control methods. It is necessary to strengthen ventilation and light transmission to prevent moisture from staying on the leaves for too long. In the early stages of the disease, only a small number of infected leaves are found.

Diseased leaves and stems should be removed in time, and carbendazim should be sprayed in time for sterilization and ventilation. When the disease is severe, spray 500 times of 80% mancozeb wettable powder or 11100 Bordeaux solution, and take turns to spray 1 time on the foliar surface every 10 days, and spray 3 or 4 times continuously.

1. Physical method: Impregnation: Immerse moso bamboo in clean water (running water or regularly replaced water) to dissolve part of the water-soluble nutrients, and fill the cells with free water to create an anoxic environment, so as to prevent and eliminate insect fungi.

Drying: Bamboo is dried or sun-dried. Through the drying process, on the one hand, it can kill the insects and bacteria due to heating, and on the other hand, it can cause the insects to be difficult to survive due to the reduction of moisture.

Electromagnetic wave radiation: Irradiation with far infrared rays and microwaves can cause the vibration and rotation of the molecules inside the bamboo. This energy absorption efficiency is very high, and it can be fatal in a short time (tens of minutes or ten minutes) to heat up the surface and interior of the bamboo at the same time to above the maximum tolerance temperature of the insect fungus.

In addition, ultraviolet light, X-rays, gamma rays, etc. can destroy the bioactive substances in the insect fungus, making the insect fungus lethal. Cooking: Heating and steaming to remove some soluble substances and kill insects and bacteria.

Most of the physical methods of one-time insecticide and sterilization are quite good, but they cannot prevent re-infection with insects and bacteria in the process of production, storage, transportation and use in the future. Therefore, a combination of physical and chemical methods is mostly used in production practice.

2. Chemical methods.

Impregnated or smeared with some pesticides or chemicals. There are many of these agents, and the easier ones are: sodium dichromate 56 parts, copper decasulfate, 33 parts, arsenic pentadecaoxide 11 parts, take the aqueous solution of the above mixture % and impregnate for 24 48 hours; Pentachlorophenol 1 3 parts + alcohol (30-40 degrees) 97 99 parts, macerated for 3 5 minutes or brushed.

Pest control of moso bamboo:1Moso bamboo blight disease:

The disease infects when the new bamboo shoots and spreads its leaves, and the disease occurs in July and September. After the new bamboo is infected, a string of brownish-purple lesions spread and expand at the branches of the bamboo poles, causing the branches to die and even the whole plant to die. Prevention and control methods.

In July and August, it was found that the branches and leaves of the new bamboo were yellow, and the diseased shoots were hooked in time and burned. Use 1000 times of 50% carbendazim wettable powder or 70% methyl tobuzine wettable powder, or 1 1 100 Bordeaux solution, spray once every 10 15 days during the leaf development period of Hsinchu, and spray 2 3 times in a row.

2.Prevention and control of bamboo seedling pests: among the pests at the seedling stage of moso bamboo, there are beetle larvae (grubs), ground tigers, mole crickets, crickets, needleworms, maggots, etc., and aphids, leafhoppers, red spiders, scale insects, bamboo borers, stinging moths, etc.

When selecting nurseries and afforestation sites, soil pest surveys should be carried out, and if the insect population density is high, pest control measures should be taken. The nursery can be evenly turned into the soil with trichlorfon powder, and then sown after half a month. After the emergence of seedlings, it is found that the underground pests are harmful to the roots of bamboo seedlings, and 500 times of trichlorfon or 800 times of marathon liquid can be used to dig a ditch between the seedling rows and irrigate it, or poison it in the seedbed hole.

Ground tigers can be hunted and killed in the soil near the killed bamboo seedlings in the early morning, or they can be lured in the seedbed with fresh grass in the evening and killed the next morning. For some sap-sucking pests such as aphids, scale insects, etc., dimethoate can be sprayed with 3000 times of liquid or 2000 times of dichlorvos, and for leaf-eating pests, it can be sprayed with trichlorfon or marathon 1000 times liquid or 8096 dichlorvos 1500 times liquid.

3.Bamboo shoot pests: The main common pests in the bamboo shoot stage are Spodoptera exigua, bamboo shoot spring flies, which eat bamboo shoots, causing bamboo shoots to retreat or bamboo pole deformity.

Spray the woodland with trichlorfon or marathon 800 times liquid, and spray once every 7 days after the bamboo shoots are unearthed, which is effective in controlling all kinds of bamboo shoot pests. In the bamboo forest where bamboo shoots occur in spring flies, dichlorvos tobacco can be applied at the adult stage.

4.Bamboo pests: The main leaf-eating pests and some sap-absorbing pests in the bamboo growth stage of moso bamboo, such as bamboo borer, bamboo locust, bamboo spotted moth, bamboo green insect and scale insects, aphids, bamboo mites, etc.

For locally occurring leaf-eating pests, trichlorfon or marathon 1000 times liquid or 80% dichlorvos 1500 times liquid can be sprayed to kill. Scale insects occur in bamboo forests, which can be sprayed with dichlorvos emulsion or marathon emulsion 1000 times at the larval stage. To control aphids and bamboo mites, you can use 50% dimethoate emulsion 1000 2000 times liquid, spray in the pest activity period, once every 10 days, 2 3 times in a row.

1. Poor ventilation is the biggest reason. The bamboo forest is too dense, and all pests like this environment, and they reproduce quickly. 2. The insect pest is not cleaned thoroughly, and the eggs are still there, which is easy to happen again.

This is closely related to the accumulation of dead leaves, and diseases and pests may hide and breed in garbage. In particular, some rotting fungi are more likely to multiply in dead leaves.
