Brontispa longissima prevention agent and using method thereof

Abstract

The invention relates to the technical field of plant protection, in particular to a brontispa longissima prevention agent and a using method thereof. The brontispa longissima prevention agent comprises, by weight, 20-25% of plant ash, 3-8% of tobacco shreds, 10-15% of sasanqua cake, 7-12% of coal ash, 10-15% of radix sophorae flavescentis, 12-15% of chaulmoogratree seeds, 8-10% of sophora alopecuroides, 8-10% of amur cork tree bark, 5-10% of Sichuanese pepper corn and the balance impurities. The method is economical, practical and easy to operate, prevention and treatment are performed simultaneously, and under the premise that the environment is not polluted, the purpose of effectively preventing harm of the brontispa longissima to palm plants is achieved.

Description

Technical field: [0001] The invention belongs to the field of plant protection, and discloses a plant pest control technology and a use method thereof, which are suitable for the control method of palm plant pests, in particular to a medicament for preventing and controlling the palm leaf beetle and a use method thereof. Background technique: [0002] Coconut leaf beetle is a major dangerous alien pest, which is a destructive pest. It ranked thirteenth in the list of 19 kinds of forestry quarantine pests released by the State Forestry Administration in 2005. Its damage part on the host is the youngest heart leaf, and the leaf will appear dead and damaged after being damaged, and the plant will die in severe cases. It has the characteristics of fast reproduction, strong destructiveness and difficult control. [0003] At present, pesticide spraying, drilling and bottle insertion, root burying, biological control, and hanging medicine bags are generally used in the market. ...

AI Technical Summary

Problems solved by technology

[0004] Pesticide spray mainly uses broad-spectrum and contact insecticides such as pyridaben and dimehypo, which can effectively kill the palm leaf beetle. A corner is likely to cause a dead angle of killing, so the killing is not complete; in addition, this kind of medicine is volatile, and the effect of continuous prevention and treatment is poor

In addition, in addition to emitting odors and polluting the air, the residual pesticides will also be washed into the surface runoff by rainwater, and then enter the water body and the soil with the surface runoff, causing serious environmental pollution.

[0005] The hanging bag method is to use Yejiaqing powder to be put into the medicine bag, and after being dissolved by rainwater, it will penetrate into the leaf core of the palm plant to kill the coconut heart beetle. Yejiaqing has dual effects of contact killing and systemic absorption, and the drug is released slowly. It has the characteristics of long period and simple operation, and also avoids the pollution caused by dust or mist droplets. However, the drug and spray pesticide method belong to chemical control. Although it has played a role in preventing and controlling the palm leaf beetle, the chemical agent itself has certain pollution to the environment.

[0006] Biological control is to continuously control the cocoa beetle by adopting the scutellaria and the gnats as natural enemies. This method is efficient, environmentally friendly and easy to operate. However, due to the strong evasiveness of the scorpion and the gnats, the cost cannot be controlled. , very risky

Contiguous large nursery stock bases can be used, but the control of palmetto plants on small green spaces is not very operable

[0007] Drilling and inserting bottles is to drill a hole at the base of the trunk, and the insect nematode cleared and watered liquid medicine flows into the tree along the hole and is conducted upwards to the top of the heart leaf. This method does not pollute the environment, because the material of palm plants is different from other plants, drilling If the hole fails to reach the woody center, the control effect is poor, and the new leaves of the plant still have symptoms of damage, and the drilled hole cannot grow and heal quickly like the phloem of other plants, and it is easy to cause multiple wounds that cannot be recovered, which will bring harm to other diseases and insect pests. way of intrusion

[0008] To bury the roots is to dig a circular ditch 50cm away from the tree head, sprinkle carbofuran in the ditch, cover the soil and pour water to dissolve the active ingredients of carbofuran into the soil and be absorbed by the plant root system, and transported to various parts of the plant through the vascular bundle. Death by poisoning is a good long-term method of killing insects; but because unhatched eggs do not eat, this method is not lethal to eggs, and larvae are escaped, so it is not an ideal method. method
