Can you use worm parapedr? Pest control of bamboo

Hello, this one can be sprayed. But grassworm is an insecticide, and unless your bamboo has worms, there is no need to spray it.

Imidacloprid can be used if there is a pest in bamboo.

Imidacloprid is mainly used to control all kinds of aphids, leafhoppers, thrips, planthoppers, yellow-striped jumping beetles, eggplant 28 star ladybugs, rice weevils, rice borers, rice negative mud worms, grubs, ground tigers, mole crickets and other pests also have good control effects.

In addition to being used for spraying, imidacloprid can also be used in the following ways:

1) Seed dressing: Seed dressing with 60% imidacloprid suspension seed coating agent, evenly wrapping the seed coating agent on the seed surface, can effectively prevent the harm of grubs, aphids, thrips, planthoppers and other pests, and the effective period can reach 80 120 days.

2) Soil treatment: when sowing wheat, potatoes, sweet potatoes, corn and other crops, 1000 2000 grams of 4% imidacloprid granules can be used, mixed with 15 20 kg of organic fertilizer, evenly sprinkled on the soil surface, and then sown, which can effectively prevent the harm of underground and aboveground pests such as aphids, thrips, planthoppers, grubs, etc., and the effective period can reach more than 90 days.

3) Hole application: When planting, 500 1000 grams of 4% imidacloprid granules, mixed with 30 50 kg of organic fertilizer, and the surrounding soil is mixed to transplant seedlings, and then covered with soil, which can also effectively prevent the harm of a variety of pests.

4) Root irrigation treatment: when tomato, eggplant, pepper, watermelon, melon and other seedlings are planted, 60% imidacloprid can also be used to suspend 1500 times of seed coating agent, combined with watering, to irrigate roots, 200 300 ml per plant, which can also effectively prevent the harm of pests and prevent the occurrence of viral diseases.

The above methods of use are better than spraying, have a longer effective period, and can also greatly reduce the number of spraying, reduce labor input, and prevent the occurrence of viral diseases. For example, the use of water-soluble fertilizer with fertile leaf amino acids can improve the resistance of bamboos to diseases and pests.

Introduction: This is a very common pest, the world has reached more than 6,000 species, China has recorded a total of more than 650 species, of which 160 species belong to agricultural pests. It is more common in the spring.

Main hazards: They often live in groups on branches, leaves or fruits, sucking the sap of plants to maintain life. If they are in large numbers, they can cause all the leaves to wilt, the fruit to shrunk and, in severe cases, the death of the whole body.

Control method: First of all, you can use manual control methods, this method is not a lot of pests, and the damaged branches and leaves are not very many, you can directly brush off the pests with a soft brush, or cut off the branches of the pests. If the quantity is very large, we can spray the agent to prevent and control early, such as 40% of the dimethoate 1,000 times the agent, every week or so, a total of two to three times.

Introduction: It is also called "honey worm", and will live in groups on the leaves, stems, flower buds, terminal buds and other positions of the plant. It is also frequented in spring.

Damage: Like the previous pest, they will also suck the sap, causing the plant to shrink and deform, and if it is severe, it will also cause its branches and leaves to completely wither and the plant to die. In addition, the substance secreted by this insect can also induce other diseases.

Control methods: To deal with this pest, we generally take the way of spraying the solution, such as 1,500 to 2,000 times the solution of imidacloprid, and the effect is good.

Brief introduction of scale insects: this is a very common pest, there are more than 6,000 kinds of pests in the world, and there are more than 650 kinds of pests recorded in China, including 160 kinds of agricultural pests. It is more common in spring.

Its hazards: often live in groups on branches, buried leaves or fruits, etc., and absorb plant juice to maintain life. If the number is too large, it can cause the leaves to wilt completely, the fruit to shrunk, and even cause the death of the whole plant in severe cases.

Control method: First of all, the manual control method can be adopted, which can be directly brushed off with a soft brush or cut off the branches of the pest for the situation that there are not many pests and not many damaged branches and leaves. If the quantity is very large, we can spray the agent for prevention and control, such as 40% of the dimethoate 1,000 times the agent, once every week or so, a total of two to three times.

Aphids. Introduction: It is also called "honey worm" and can live in groups on leaves, stems, buds, terminal buds and other parts. Its perennial season is also in spring.

Damage: Like pests, they will also suck the sap, causing the plant to shrink, deform, and in severe cases, it will cause its branches and leaves to completely wither, leading to the death of the plant. In addition, the substance secreted by this insect can also cause other diseases.

Precautionary measures: For this kind of pests, we generally take the way of spraying, such as 1500-2000 times of imidacloprid, which has a good effect.

Bamboo long spider webs spray leaves or should choose different methods to control. For the case where the bamboo plant is covered with cobwebs, spider web medicine is an effective option. However, if there are only slight young leaves on the leaves, it is not enough to spray directly with a spider web drug, because the drug may cause harm to the plant, so other feasible methods need to be considered.

For the situation where the bamboo is covered with spider webs, spider web medicine is an effective control tool. Insecticides such as organophosphates, carbamate and pyrethroids in spider web medicine can effectively kill spiders on bamboos and their webs. The use of spider web medicine is more common on indoor bamboo, as fewer cobwebs form indoors.

However, for bamboos with only slightly young leaves, the use of cobwebs is not the best choice because the medicine may cause damage to the plant. In this case, the manual removal method can be used. Wipe off the young leaves, and if necessary, try adding detergent to the water to thoroughly clean the cobwebs from the young leaves.

In addition, a high-pressure water gun can be used to clean the cobwebs on the stems and petioles. This effectively controls the spread of spiders.

In short, for the cobwebs on bamboo plants, different control methods need to be selected according to the actual situation. Spider web medicine is a powerful way to control the overgrowth of spider webs in bamboo, but in the case of slight young leaves, manual removal is required to ensure the normal and healthy growth of the plant. The ultimate goal is to reduce the harm of spiders to bamboos as much as possible and protect the healthy growth of bamboo.

Aphids have strong reproduction and adaptability, and it is difficult to achieve the best results with various control methods. For aphid control, it is important to pay close attention to ** to avoid the occurrence of aphids in large numbers.

When it occurs sporadically on potted flowers, you can use a brush dipped in water to brush it off, but be careful not to hurt the young shoots and young leaves when brushing. The aphids under the brush should be cleaned up in time. In winter and spring, we should often eradicate weeds in the edge of the field, spray dimethoate to eliminate aphids on the overwintering host, and reduce the source of insects.

In daily life, you can use 50 grams of fresh chili pepper or dried red pepper, add 30 to 50 grams of water, boil for about half an hour, and sprinkle the affected plants with its filtrate to have special effects. Or use 3 to 4 grams of washing powder, add 100 grams of water, stir into a solution and spray 2 to 3 times continuously, the prevention and control effect is up to 100. Add 600 to 800 times the solution of water with "wind oil essence", and spray the pests carefully with a sprayer to make the insects stained with the potion.

The effect of killing aphids and scale insects and other pests is above 95, and there will be no pesticide damage to plants. You can also press 1:4 for laundry detergent, urea and water

The ratio of 100, stirred into a mixture, is used to spray the plants, which can receive the effect of insecticide and fertilization.

For the control of chemical agents, 50 aphid mist ultra-fine wettable powder 2000 times or 20 methocarb EC 1500 times, 50 aphid pine EC 1000 1500 times, 50 octathion EC 2000 times, 80 dichlorvos EC 1000 times.

Other biological control methods can also be combined with general biological control methods such as protection of ladybugs, lacewings and other natural enemies, the application of fungi, artificial trapping and killing and other biological control methods, the removal of dead branches and weeds and other pests and diseases, breeding and promotion of resistant varieties, the application of pesticides, etc., the best way is to adapt measures to local conditions, comprehensive control. Combined with cultivation measures, ventilation, water and fertilizer control, protection and breeding to release natural enemies, etc., the occurrence of aphids in a large area will be prevented to a certain extent.

Use a bag of imidacloprid or acetamiprid mixed with 15 kg of water, evenly spray the whole plant, and kill it all again in 3-5 days.

It is best to use pesticides, or pesticides made from eco-friendly plants.

Bamboo is rarely found with pests and diseases. The place may not be suitable, and it should be placed in a cool and ventilated place in summer.

In this case, the foliage can be rinsed with water. If the drug is not used properly, it may cause damage to bamboo.

Bamboos like warmth, tolerate semi-shade, and are not cold-tolerant. The key to cultivation is to master watering. Watering too much, easy to cause rotten roots, too dry, branches and leaves will turn yellow, potting soil requires to see dry and wet, and often use a watering can with fine water to spray water on the leaf surface.

In winter, water should be moderate, and the foliage can be sprayed every seven to ten days.

Since the beginning of summer, the Chinese bamboo has seen yellowing of needles, and many red insects have appeared. Small insects can form spiderweb-like objects on needles.
