The use of smoke agents can effectively prevent pests and diseases in greenhouses and greenhouse vegetables, and users are willing to accept them. The main reasons why the smoker prevention and control technology is popular are:
First, good transparency. The effective particles released by the smoke agent are very small, with good multi-directional penetration and deposition performance, which can effectively increase the coverage area, attach different orientations of plants, and evenly penetrate into the dense shelter of plants, increase pesticides and pests. Contact opportunities. There is no leakage in one operation, and stable control effects can be obtained.
Second, no water. The smoke agent uses smoke to disperse the solid particles of the pesticide in the space inside the booth. Its special significance is that no water is needed. This will not form a conventional spray (with water dispensing) to increase the humidity of the greenhouse, thereby reducing the difficulty of passive cooling in management.
Third, the provincial medical equipment. The smoke agent is a smoked product ignited by a dark fire. When applied
No sprayers, dusters and any other medical equipment are required.
Fourth, easy to operate. The application of the smoking agent is extremely convenient. Usually in the evening before closing the shed, according to the shed
The smoke dose is approved for the room area and then placed evenly. From the inside, the smoke is ignited by the dark fire, and the light is ignited one after another. Finally, the shed door is exited, and the door is closed and smoked overnight.
Fifth, work efficiency is fast. According to the operating procedures and precautions of the smoke agent, it is absolutely labor-saving.
According to the current shed area, the smoke agent can be processed in a few minutes at a time. The spraying (loading water, dispensing, spraying, and finally washing the medicine), the spraying of the powdering operation has to be busy for hours. Show the difference between the minutes and the time. And it is used in the evening without taking up the daytime work time.
Sixth, the solution to sorrow; shed greenhouse vegetables planted in many low temperature, high humidity and low light conditions, in the management of mistakes are prone to pests and diseases, always worried about prevention and control work. Especially in rainy days and when it is sick, it is difficult to keep warm and wet. In addition, it is difficult to penetrate the plant densely, which is also troublesome. The application of the smoke agent can relieve the problem of humidity and infiltration. Stabilize the vouchers to ease the psychological pressure of sorrow.
To use the smoke agent to be effective, you need to pay attention to the following good and good things:
First, understand the scope of prevention and control of smoke agents, and select the right products according to the actual situation of pests and diseases.
In particular, the subject of treatment should be carefully identified based on the active ingredients and labels of the smoke agent. At present, pesticide smoke agents are classified into insecticides and bactericidal smoke agents. The insecticide is a dichlorvos agent, which treats vegetable pests (aphids, whiteflies, etc.) and pests in the shed. The bactericidal smoke agent includes chlorothalonil, sclerotium net, Tecto and procymidone and its mixed smoke agent (hundred rot, multi-fudant, etc.). They are responsible for vegetable diseases. The chlorothalonil agent is effective against various diseases such as downy mildew, anthracnose and leaf blight. Sclerotium, Tecto and Pythium have specific effects on gray mold.
Second, understand the effective content of smoke agents, and approve the actual dosage according to the area of ​​prevention and control.
Usually, each type of smoke agent is marked with usage. When using 45% bacteria, please use 200-250 grams per 10 mu, 10% procymidone when using 250-300 grams per acre, 20% Tec multi-toner when using 300- per mu 500 g. Use 22% dichlorvos smoker 500g per acre. However, due to the different names of smoke agents, due to the different manufacturers and registered pesticides, there is a widespread difference in effective content, which brings great confusion to users. Taking chlorothalonil as an example, the effective content is divided into two types: 2.5%, 10%, 20%, 28%, 30%, and 45%. Therefore, when selecting a variety of smoke agents of a certain agent, it is necessary to repeatedly calculate the actual effective amount. Otherwise, use less time to reduce the effect, use a lot of time to harm.
Third, understand the precautions of the smoke agent, and operate accurately according to various regulations.
The application of the smoke agent is controlled by the pre-infection or the initial treatment of the disease, and cannot be treated late. The application period is 7-10 days for one application and 4-5 times for the whole life. The greenhouses and greenhouses to be applied should be tight, and there should be no leaking holes to prevent "smoke" and reduce the effectiveness of control. Keep the smoke agent away from flammable materials and prevent fire when stored and used. It is best to apply the smoke agent before the closed shed in the evening to avoid the application during the day when the heat is repellent, otherwise the smoke agent will not settle evenly and affect the disease prevention effect. To arrange the ignition path of the smoke agent, do not stay in the smoke for a long time or do other management activities to avoid inhalation of smoke poisoning. Safe storage, especially pay attention to some "bad" smoke agents, there is a danger of spontaneous combustion and self-explosion. Although the application of the smoke agent is very safe, the application amount cannot be "hate the disease and take the medicine", and it is free to exceed the prescribed range, otherwise the pharmacy damage of the whole shed will occur.
